+### Netty 笔记
+
+#### 1.Netty对三种I/O模式的支持
+
+image-20220124110420220
+
+
+
+##### Netty并不是只支持过NIO,但是不建议(depercate)阻塞I/O(BIO/OIO)
+
+- 连接数高的情况下:阻塞 -> 消耗源、效率低
+
+##### Netty也不建议(depercate)使用AIO
+
+- AIO在Windows 下比较成熟,但是很少用来做服务器
+- Linux 常用来做服务器,但是AIO实现不够成熟
+- Linux 的AIO相比NIO的性能没有显著的提升,反而会为开发者带来高额的维护成本
+
+##### Netty和JDK NIO在Linux下,都是基于epoll实现,为什么要用Netty?
+
+- Netty 暴露了更多的可用参数,如:
+ - JDK 的 NIO 默认实现是水平触发
+ - Netty 是边缘触发(默认)和水平触发可以切换
+- Netty 实现的垃圾回收更少、性能更好
+
+
+
+#### 2.Netty NIO 中的Reactor 开发模式
+
+Netty 三种开发模式版本
+
+BIO 下是 Thread-Per-Connection
+
+image-20220124112504631
+
+
+
+***Thread-Per-Connection:对应每个连接都有1个线程处理,1个线程同时处理:读取、解码、计算、编码、发送***
+
+
+
+NIO 下是 Reactor
+
+image-20220124112753682
+
+
+
+***Reactor 多线程模式,由多个线程负责:读取、发送,由线程池负责处理:解码、计算、编码***
+
+***Reactor 主从多线程模式,由单独mainReactor 单线程负责接收请求,subReactor和 Reactor 多线程模式一致***
+
+
+
+AIO 下是 Proactor
+
+Reactor 是一种开发模式,模式的核心流程:
+
+> 注册感兴趣的事件 -> 扫描是否有感兴趣的事件发生 -> 事件发生后做出相应的处理
+
+
+
+##### Netty下使用 NIO 示范例
+
+- Reactor 单线程模式
+
+```java
+//线程数1
+EventLoopGroup eventGroup = new NioEventLoopGroup(1);
+
+ServerBootStrap serverBootStrap = new ServerBootStrap();
+serverBootStrap.group(eventGroup);
+```
+
+- Reactor 多线程模式
+
+```java
+//多线程,不传具体的线程数时,Netty会根据CPU核心数分配
+EventLoopGroup eventGroup = new NioEventLoopGroup();
+
+ServerBootStrap serverBootStrap = new ServerBootStrap();
+serverBootStrap.group(serverBootStrap);
+```
+
+- Reactor 主从多线程模式
+
+```java
+// 主线程负责接收请求 acceptor,是单线程
+EventLoopGroup bossGroup = new NioEventLoopGroup();
+// 从线程负责:读取、解码、计算、编码、发送,是多线程
+EventLoopGroup workerGroup = new NioEventLoopGroup();
+
+SeverBootStrap serverBootStrap = new ServerBootStrap();
+serverBootStrap.group(bossGroup, workerGroup);
+```
+
+
+
+##### Netty 支持主从 Reactor 源码分析
+
+1.初始化 Main EventLoopGroup
+
+```java
+public abstract class AbstractBootstrap, C extends Channel> implements Cloneable {
+
+ // main Event Loop Group
+ volatile EventLoopGroup group;
+
+ ....
+
+ // 初始化 mian Event Loop Group 方法
+ public B group(EventLoopGroup group) {
+ ObjectUtil.checkNotNull(group, "group");
+ if (this.group != null) {
+ throw new IllegalStateException("group set already");
+ }
+ this.group = group;
+ return self();
+ }
+
+ ....
+}
+```
+
+2. 初始化 Worker EventLoopGroup
+
+```java
+public class ServerBootstrap extends AbstractBootstrap {
+
+ // woker Events Loop Group
+ private volatile EventLoopGroup childGroup;
+ .....
+
+ public ServerBootstrap group(EventLoopGroup parentGroup, EventLoopGroup childGroup) {
+ super.group(parentGroup);
+ ObjectUtil.checkNotNull(childGroup, "childGroup");
+ if (this.childGroup != null) {
+ throw new IllegalStateException("childGroup set already");
+ }
+ // 初始化 worker Event Loop Group 方法
+ this.childGroup = childGroup;
+ return this;
+ }
+
+ ....
+}
+```
+
+3. MainEventLoopGroup 和 WorkerEventLoop 绑定# bind(),并实现新建和初始化 SocketChannel 绑定到 MainEventLoopGroup中
+
+```java
+// 绑定 地址:端口
+public ChannelFuture bind(SocketAddress localAddress) {
+ validate();
+ return doBind(ObjectUtil.checkNotNull(localAddress, "localAddress"));
+}
+
+// 绑定逻辑
+private ChannelFuture doBind(final SocketAddress localAddress) {
+ // 初始化 & 注册 MainEventLoopGroup
+ final ChannelFuture regFuture = initAndRegister();
+ final Channel channel = regFuture.channel();
+ ....
+}
+
+// 初始化 & 注册 MainEventLoopGroup
+final ChannelFuture initAndRegister() {
+ Channel channel = null;
+ try {
+ // 创建新的 ServerSocketChannel
+ channel = channelFactory.newChannel();
+ // 初始化 ServerSocketChannel 中的 Handler
+ init(channel);
+ } catch (Throwable t) {
+ if (channel != null) {
+ // channel can be null if newChannel crashed (eg SocketException("too many open files"))
+ channel.unsafe().closeForcibly();
+ // as the Channel is not registered yet we need to force the usage of the GlobalEventExecutor
+ return new DefaultChannelPromise(channel, GlobalEventExecutor.INSTANCE).setFailure(t);
+ }
+ // as the Channel is not registered yet we need to force the usage of the GlobalEventExecutor
+ return new DefaultChannelPromise(new FailedChannel(), GlobalEventExecutor.INSTANCE).setFailure(t);
+ }
+
+ // 将 ServerSocketChannel 注册到 MainEventLoop 中
+ // 因为端口和地址 只有1个,channel只能被注册一次,所以 MainEventLoopGroup 是单线程的
+ ChannelFuture regFuture = config().group().register(channel);
+ if (regFuture.cause() != null) {
+ if (channel.isRegistered()) {
+ channel.close();
+ } else {
+ channel.unsafe().closeForcibly();
+ }
+ }
+ ...
+}
+
+```
+
+4. WorkerEventLoopGroup 和 SocketChannel 绑定关系
+
+```java
+private static class ServerBootstrapAcceptor extends ChannelInboundHandlerAdapter {
+ @Override
+ @SuppressWarnings("unchecked")
+ public void channelRead(ChannelHandlerContext ctx, Object msg) {
+ // 每次读取都是一个 SocketChannel
+ final Channel child = (Channel) msg;
+
+ child.pipeline().addLast(childHandler);
+
+ setChannelOptions(child, childOptions, logger);
+
+ for (Entry, Object> e: childAttrs) {
+ child.attr((AttributeKey) e.getKey()).set(e.getValue());
+ }
+
+ try {
+ // 将 SocketChannel 注册到 workerEventLoopGroup中
+ childGroup.register(child).addListener(new ChannelFutureListener() {
+ @Override
+ public void operationComplete(ChannelFuture future) throws Exception {
+ if (!future.isSuccess()) {
+ forceClose(child, future.cause());
+ }
+ }
+ });
+ } catch (Throwable t) {
+ forceClose(child, t);
+ }
+ }
+}
+```
+
+
+
+
+
+#### 3.Netty 粘包/半包解决方案
+
+关于半包的主要原因:
+
+- 发送写入数据> 套接字缓冲区大小
+- 发送的数据大于协议 MTU(Maximum Transmission Unit,最大传输单元),必须拆包
+
+image-20220124144456949
+
+
+
+
+
+关于粘包的主要原因:
+
+- 发送方每次写入数据> 套接字缓冲区大小
+- 接收方读取套接字缓冲区不够及时
+
+
+
+换个角度看原因:
+
+- 收发时:一个发送可能多次接收,多个发送可能被一次接收
+- 传输时:一个发送可能占用多个传输包,多个发送可能公用一个传输包
+
+
+
+导致粘包/半包的根本原因:
+
+TCP 是流式协议,消息无边界
+
+> 提醒:UDP 像邮寄的包裹,虽然一次运输多个,但每个包裹都是 "界限",一个一个签收,所以无粘包、半包问题
+
+
+
+***解决粘包和半包的手段: 找出消息的边界***
+
+- 方式一:***短连接***(不推荐)
+ - 手段:TCP 连接改成短连接,一个请求一个短连接,建立连接到释放连接之间的信息即为传输信息
+ - 优点:简单
+ - 缺点:效率低下
+
+- 方式二:***固定长度***(不推荐)
+ - 手段:满足固定长度即可
+ - 优点:简单
+ - 缺点:浪费空间
+
+- 方式三:***分隔符***(推荐)
+ - 手段:用确定分隔符切割
+ - 优点:空间不浪费,也比较简单
+ - 缺点:内容本身出现分隔符时需要转义,所以需要扫描内容
+
+- 方式四:***固定长度字段存个内容的长度信息***(推荐+)
+ - 手段:先解析固定长度的字段获取长度,然后读取后续的内容
+ - 优点:精确定位用户数据,内容也不用转义
+ - 缺点:长度理论上是有限制,需要提前预知可能的最大长度从而定义长度占用字节数
+
+- 方式五:***序列化方式***(根据场景衡量)
+ - 手段:每种都不同,例如JSON 可以看{} 是否应己成对
+ - 优缺点:衡量实际场景,很多是对现有协议的支持
+
+
+
+##### Netty 粘包/半包 解决方案
+
+- 固定长度
+ - 解码:FixedLengthFrameDecoder
+- 分隔符
+ - 解码:DelimiterBasedFrameDecoder
+- 固定长度存个内容长度字段
+ - 解码:LengthFieldBasedFrameDecoder
+ - 编码:LengthFieldPerpender

+ /**
+ * 通过 @Configuration注解 注入一个Bean
+ */
+ @Bean("dog")
+ public Animal getDog() {

+ }
+
+}
+```
+
+

+ * such as the context's ClassLoader and post-processors.
+ * @param beanFactory the BeanFactory to configure
+ * 配置工厂的标准上下文特征,比如上下文的ClassLoader和post-processors

+
+ // 注册上下文enviroment配置的引用
+ // 用于做属性转换
+ beanFactory.addPropertyEditorRegistrar(new ResourceEditorRegistrar(this, getEnvironment()));
+
+ // Configure the bean factory with context callbacks.
+ // 使用上下文回调配置 Bean 工厂
+ // 在工厂的 beanPostProcessor 属性中添加Bean的后置处理器,beanPostProcessor是一个ArrayList
+ beanFactory.addBeanPostProcessor(new ApplicationContextAwareProcessor(this));
+ // 在工厂的忽略依赖接口ignoreDependencyInterface列表中添加Aware系列的接口
+ // 以下Aware接口由 ApplicationContextAwareProcessor 后置处理器处理
+ beanFactory.ignoreDependencyInterface(EnvironmentAware.class);
+ beanFactory.ignoreDependencyInterface(EmbeddedValueResolverAware.class);
+ beanFactory.ignoreDependencyInterface(ResourceLoaderAware.class);
+ beanFactory.ignoreDependencyInterface(ApplicationEventPublisherAware.class);
+ beanFactory.ignoreDependencyInterface(MessageSourceAware.class);
+ beanFactory.ignoreDependencyInterface(ApplicationContextAware.class);
+
+ // BeanFactory interface not registered as resolvable type in a plain factory.
+ // MessageSource registered (and found for autowiring) as a bean.
+ // 在普通的工厂中,BeanFactory接口并没有按照resolvable类型进行注册
+ // MessageSource被注册成一个Bean(并被自动注入)
+
+ //BeanFactory.class为key,beanFactory为value放入到了beanFactory的resolvableDependencies属性中
+ //resolvableDependencies是一个ConcurrentHashMap,映射依赖类型和对应的被注入的value
+ //这样的话BeanFactory/ApplicationContext虽然没有以bean的方式被定义在工厂中,
+ //但是也能够支持自动注入,因为他处于resolvableDependencies属性中
+
+ // 向BeanFacotry添加一些依赖,需要解析依赖的时候指向自身
+ beanFactory.registerResolvableDependency(BeanFactory.class, beanFactory);
+ // 再将上下文的一些接口与上下文本身做映射,一一放入到resolvableDependencies中
+ beanFactory.registerResolvableDependency(ResourceLoader.class, this);

+ }
+ }
+```
+
+
+
+#### 2.重写BeanFactory,在BeanFactory创建后进一步设置:postProcessBeanFactory()
+
+- 作用是
+ - 留给开发者的扩展点,通过子类重写,在BeanFactory完成创建后做进一步设置
+ - 如添加WebApplicationContextServletContextAwareProcessor后置处理器,给Web环境下的Servlet作用域进行设置:Request、Session
+
+- postProcessBeanFacotory()方法
+
+```java
+ protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
+ // 调用父类的GenericWebApplicationContext#postProcessBeanFacotory方法
+ super.postProcessBeanFactory(beanFactory);
+ if (!ObjectUtils.isEmpty(this.basePackages)) {
+ this.scanner.scan(this.basePackages);
+ }
+
+ if (!this.annotatedClasses.isEmpty()) {
+ this.reader.register(ClassUtils.toClassArray(this.annotatedClasses));
+ }
+
+ }
+```
+
+- 在Web环境下注册WebApplicationContextServletContextAwareProcessor后置处理器
+
+```java
+ /**
+ * Register ServletContextAwareProcessor.
+ * @see ServletContextAwareProcessor
+ */
+ @Override
+ protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
+ // 添加WebApplicationContextServletContextAwareProcessor后置处理器
+ beanFactory.addBeanPostProcessor(new WebApplicationContextServletContextAwareProcessor(this));
+ // 忽略ServletContextAware
+ beanFactory.ignoreDependencyInterface(ServletContextAware.class);
+ // 定义Web环境下的Servlet作用域,比如:Request、Session
+ registerWebApplicationScopes();
+ }
+
+```
+
+
+
+
+
+#### 3.调用所有注册的BeanFactoryPostProcessor的Bean
+
+- 作用
+
+ - 框架自身的BeanFactoryPostProcessor或BeanDefinitionRegistoryPostProcessor初始化Bean的定义或属性
+
+ - 调用BeanDefinitionRegistryPostProcessor实现向容器内添加Bean的定义
+
+ - ```java
+ // 调用时机:在BeanFactory标准初始化之后调用,这时所有的Bean定义已经保存加载到BeanFactory,但是Bean的实例还未创建
+ // 作用:来定制和修改BeanFactory内容,如添加一个Bean
+ @Component
+ public class MyBeanDefinitionRegistry implements BeanDefinitionRegistryPostProcessor {
+
+ /**
+ * 通过BeanDefinitionRegistryPostProcessor
+ */
+ @Override
+ public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry beanDefinitionRegistry) throws BeansException {
+ RootBeanDefinition rootBeanDefinition = new RootBeanDefinition();
+ rootBeanDefinition.setBeanClass(Monkey.class);
+ beanDefinitionRegistry.registerBeanDefinition("monkey", rootBeanDefinition);
+ }

+## 框架初始化器实战
+
+### 思路
+
+添加一个框架初始化器,在Springboot初始化阶段中添加一个自定义的环境属性配置
+
+- 添加一个自定义的框架初始化类,实现 ApplicationContextInitializer 接口
+ - 重写 initialize(ConfigurableApplicationContext configurableApplicationContext) 方法
+ - 获取系统属性 ConfigurableEnvirnoment env = configurableApplicationContext.getEnvironment();
+ - 添加系统属性 env.getPropertySource().addLast(XXX);
+- 加载这个自定义框架初始化类
+ - 方式一
+ - 在 /META/spring.factories 中配置 org.springframe.context.ApplicationContextInitializer = 自定义框架初始化器
+ - 方式二
+ - 在springApplication.run()前,通过springApplicaiton.addInitializers()方法,自定义框架初始化器
+ - 方式三
+ - 在application.properties 中配置 context.initializer.classes = 自定义框架初始化器
+
+
+
+### 方式一代码
+
+#### 添加自定义初始化器
+
+```java
+@Order(1) // 设置执行顺序
+public class FirstInitializer implements ApplicationContextInitializer {
+
+ private static final Logger logger = LoggerFactory.getLogger(FirstInitializer.class);
+
+ @Override
+ public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
+ // 获取系统属性
+ ConfigurableEnvironment environment =
+ configurableApplicationContext.getEnvironment();
+
+ // 设置自定义属性
+ Map attributeMap = new HashMap();
+ attributeMap.put("firstKey", "firstValue");
+
+ // 添加自定义属性
+ MapPropertySource mapPropertySource = new MapPropertySource("firstInitializer", attributeMap);
+ environment.getPropertySources().addLast(mapPropertySource);
+ logger.info("设置框架初始化器【ApplicationContextInitializer】成功 : run firstInitializer");
+ }
+}
+```
+
+
+
+#### 在 /META/spring.factories 中配置 自定义初始化器类的Reference
+
+```java
+# 通过系统初始化器,设置自定义环境属性
+org.springframework.context.ApplicationContextInitializer=\
+ com.example.springboot.source.code.analysis.initializer.FirstInitializer
+```
+
+
+
+### 方式二代码
+
+#### 添加自定义初始化器
+
+```java
+@Order(2) // 设置执行顺序
+public class SecondInitializer implements ApplicationContextInitializer {
+
+ private static final Logger logger = LoggerFactory.getLogger(SecondInitializer.class);
+
+ @Override
+ public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
+ // 获取系统属性
+ ConfigurableEnvironment environment =
+ configurableApplicationContext.getEnvironment();
+
+ // 设置自定义属性
+ Map attributeMap = new HashMap();
+ attributeMap.put("secondKey", "secondValue");
+
+ // 添加自定义属性
+ MapPropertySource mapPropertySource = new MapPropertySource("secondInitializer", attributeMap);
+ environment.getPropertySources().addLast(mapPropertySource);
+ logger.info("设置框架初始化器【ApplicationContextInitializer】成功 : run secondInitializer");
+ }
+}
+```
+
+
+
+#### 在 springApplication#run方法执行前,加载自定义初始化器
+
+```java
+@SpringBootApplication
+public class SpringbootSourceCodeAnalysisApplication {
+
+ public static void main(String[] args) {
+ // SpringApplication.run(SpringbootSourceCodeAnalysisApplication.class, args);
+ SpringApplication springApplication = new SpringApplication(SpringbootSourceCodeAnalysisApplication.class);
+
+ // 手动添加一个框架的初始化器
+ springApplication.addInitializers(new SecondInitializer());
+
+ springApplication.run();
+
+ }
+}
+```
+
+
+
+### 方式三代码
+
+#### 添加自定义初始化器
+
+```java
+@Order(3) // 设置执行顺序
+public class ThirdInitializer implements ApplicationContextInitializer {
+
+ private static final Logger logger = LoggerFactory.getLogger(ThirdInitializer.class);
+
+ @Override
+ public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
+ // 获取系统属性
+ ConfigurableEnvironment environment =
+ configurableApplicationContext.getEnvironment();
+
+ // 设置自定义属性
+ Map attributeMap = new HashMap();
+ attributeMap.put("thirdKey", "thirdValue");
+
+ // 添加自定义属性
+ MapPropertySource mapPropertySource = new MapPropertySource("thirdInitializer", attributeMap);
+ environment.getPropertySources().addLast(mapPropertySource);
+ logger.info("设置框架初始化器【ApplicationContextInitializer】成功 : run thirdInitializer");
+ }
+}
+```
+
+
+
+#### 在 application.property 配置文件中 添加自定义初始器
+
+```java
+# 通过系统初始化器,设置环境属性
+context.initializer.classes=\
+ com.example.springboot.source.code.analysis.initializer.ThirdInitializer
+```

+### SpringFactoriesLoader 介绍
+
+> org.springframework.core.io.support.SpringFactoriesLoader
+
+```java
+/**
+ * General purpose factory loading mechanism for internal use within the framework.
+ *
+ *
{@code SpringFactoriesLoader} {@linkplain #loadFactories loads} and instantiates
+ * factories of a given type from {@value #FACTORIES_RESOURCE_LOCATION} files which
+ * may be present in multiple JAR files in the classpath. The {@code spring.factories}
+ * file must be in {@link Properties} format, where the key is the fully qualified
+ * name of the interface or abstract class, and the value is a comma-separated list of
+ * implementation class names. For example:
+ *
+ *
Typically used within web applications that require some programmatic initialization
+ * of the application context. For example, registering property sources or activating
+ * profiles against the {@linkplain ConfigurableApplicationContext#getEnvironment()
+ * context's environment}. See {@code ContextLoader} and {@code FrameworkServlet} support
+ * for declaring a "contextInitializerClasses" context-param and init-param, respectively.
+ *
+ *
As of Spring 3.0, an ApplicationListener can generically declare the event type
+ * that it is interested in. When registered with a Spring ApplicationContext, events
+ * will be filtered accordingly, with the listener getting invoked for matching event
+ * objects only.
+ *
+ * @author Rod Johnson
+ * @author Juergen Hoeller
+ * @param the specific ApplicationEvent subclass to listen to
+ * @see org.springframework.context.event.ApplicationEventMulticaster

+
+- SpringBoot中可以通过实现ApplicationListener接口类,来完成系统事件的监听
+- 这个监听器是机遇java.util.EventListener标准来实现的,是一个ObServer观察者模式

+ */
+ public interface ApplicationEventMulticaster {
+ ```
+
+- 用来管理ApplicationListener事件监听器,比如事件监听器的添加、删除等
+- 用来遍历所有的ApplicationListener事件监听器,触发ApplicationEvent事件

+### 自定义监听器实战
+
+#### 实现方式一
+
+- 实现ApplicationListener接口,ApplicationListener声明感兴趣的事件
+
+```java
+@Order(1)
+public class FirstListener implements ApplicationListener {
+
+ private final static Logger logger = LoggerFactory.getLogger(FirstListener.class);
+
+ @Override
+ public void onApplicationEvent(ApplicationStartedEvent event) {
+ logger.info("设置框架事件监听器【ApplicationListener】成功 : run firstListener");
+
+ }
+}
+
+```
+
+- 在spring.factories 配置文件中配置FirstListener事件监听器,key值为org.springframework.context.ApplicationListener
+
+```java
+# 通过系统事件监听器,设置自定义事件监听器
+org.springframework.context.ApplicationListener=\
+ com.example.springboot.source.code.analysis.listener.FirstListener
+```
+
+
+
+#### 实现方式三
+
+- 实现ApplicationListener接口,声明感兴趣的事件ApplicationListener
+
+```java
+@Order(3)
+public class ThirdListener implements ApplicationListener {
+
+ private final static Logger logger = LoggerFactory.getLogger(ThirdListener.class);
+
+ @Override
+ public void onApplicationEvent(ApplicationStartedEvent event) {
+ logger.info("设置框架事件监听器【ApplicationListener】成功 : run thirdListener");
+ }
+}
+```
+
+- 在application.properties 内配置事件监听器,key值为context.listener.classes
+
+```java
+# 通过系统事件监听器,监听事件
+context.listener.classes=\
+ com.example.springboot.source.code.analysis.listener.ThirdListener,\
+```
+
+> application.properties 内配置的 conext.listener.classes 事件监听器执行优先级最高
+>
+> ```java
+> // context.listener.classes 是通过 DelegatingApplicationListener 委派给 ApplicationListener
+> public class DelegatingApplicationListener implements ApplicationListener, Ordered {
+> private static final String PROPERTY_NAME = "context.listener.classes";
+> // 在委派过程中,DelegatingApplicationListener 会将 order 优先级设置为最高
+> private int order = 0;
+> private SimpleApplicationEventMulticaster multicaster;
+>
+> ```
+
+
+
+#### 实现方式四
+
+- 实现SmartApplicationListener接口
+
+```java
+@Order(4)
+public class FourthListener implements SmartApplicationListener {
+
+ private final static Logger logger = LoggerFactory.getLogger(FourthListener.class);
+
+ // 通过重写 supportEventType()方法 判断该监听器对哪些事件感兴趣
+ @Override
+ public boolean supportsEventType(Class eventType) {
+ return ApplicationStartedEvent.class.isAssignableFrom(eventType)
+ || ApplicationPreparedEvent.class.isAssignableFrom(eventType);
+ }
+
+ // 编写事件触发逻辑
+ @Override
+ public void onApplicationEvent(ApplicationEvent event) {
+ logger.info("设置框架事件监听器【SmartApplicationListener】成功 : run fourthListener");
+ }
+}
+
+```
+
+- 可以通过spring.factories 或 application.properties 或 new SpringApplication().addListeners() 三种方式注入该事件
+
+
+
+#### 通过 ContextRefershedEvent 获取 Spirng 上下文
+
+- 实现ApplicationListener接口,关注ContextRefershedEvent事件
+
+```java
+@Component
+@Order(1)
+public class ApplicationContextContainer implements ApplicationListener {
+
+ private ApplicationContext applicationContext;
+
+ private static ApplicationContextContainer applicationContextContainer;
+
+ // 当容器上下文刷新完成后,会触发此方法
+ @Override
+ public void onApplicationEvent(@Nullable ContextRefreshedEvent event) {
+ // 双重检测锁,获取当前容器上下文
+ if (event != null && applicationContext == null) {
+ synchronized (ApplicationContextContainer.class) {
+ if (applicationContext == null) {
+ applicationContext = event.getApplicationContext();
+ }
+ }
+ }
+ applicationContextContainer = this;
+ }
+
+ // 返回当前自定义容器类的实例
+ public static ApplicationContextContainer getInstance() {
+ return applicationContextContainer;
+ }
+
+ // 从 Spring 容器中获取 Bean
+ public T getBean(Class clazz) {
+ return applicationContext.getBean(clazz);
+ }
+}
+```
+
+- 测试,通过普通方法获取Spring容器中的Bean
+
+```java
+@SpringBootTest(classes = SpringbootSourceCodeAnalysisApplication.class)
+@RunWith(SpringJUnit4ClassRunner.class)
+public class SpringbootSourceCodeAnalysisApplicationTests {
+
+ // 测试ContextRefreshEvent事件
+ @Test
+ public void testContextRefreshEvent() {
+ WeatherRunListener weatherRunListener = ApplicationContextContainer.getInstance().getBean(WeatherRunListener.class);
+ weatherRunListener.snow();
+ weatherRunListener.rain();
+ }
+```

+### IoC思想
+
+
+
+image-20210921195432177
+
+
+
+- 松耦合
+ - 降低强耦合关系,对象与对象之间的依赖不用new,而是通过Spring容器@Autowired注入完成
+- 灵活性
+ - 不需要初始化使用类的构造方法,而是通过Spring容器完成初始化工作
+- 可维护
+ - 通过Spring xml或注解 的方式,可以清晰的了解类与类之间的依赖关系,提升可读性

+### SpringBoot集成Swagger用例
+
+
+
+#### 什么是 Swagger 2
+
+**Swagger 2** 是一个开源软件框架,可以帮助开发人员设计、构建、记录和使用 **RESTful Web** 服务,它将代码和文档融为一体,可以完美解决文档编写繁琐、维护不方便等问题。使得开发人员可以将大部分精力集中到业务中,而不是繁杂琐碎的文档中。
+
+
+
+ #### 在Maven工程中引入Swagger和Swagger UI
+
+```java
+
+ io.springfox
+ springfox-swagger2
+ 2.9.2
+
+
+
+ io.springfox
+ springfox-swagger-ui
+ 2.9.2
+
+```
+
+
+
+#### 配置Swagger Bean
+
+```java
+@Configuration
+@EnableSwagger2
+public class SwaggerConfig {
+
+ /**
+ * 注入SwaggerDocketBean
+ */
+ @Bean
+ public Docket docket() {
+ return new Docket(DocumentationType.SWAGGER_2)
+ .apiInfo(apiInfo())
+ .select()
+ .apis(RequestHandlerSelectors.basePackage("com.ipman.swagger.sample.controller"))
+ .paths(PathSelectors.any())
+ .build();
+ }
+
+ /**
+ * 配置Swagger文档说明
+ */
+ private ApiInfo apiInfo() {
+ return new ApiInfoBuilder()
+ .title("API测试文档")
+ .description("DEMO项目的接口测试文档")
+ .termsOfServiceUrl("http://www.hangge.com")
+ .version("1.0")
+ .contact(new Contact("ipman",
+ "http://www.ipman.com",
+ "ipipman@163.com"))
+ .build();
+ }
+}
+```
+
+
+
+#### 编写Controller,配置Swagger接口文档说明
+
+```java
+@RestController
+@Api(tags = "用户数据接口") // @Api 注解标注在类上用来描述整个 Controller 信息。
+public class UserController {
+
+ /**
+ * @ApiOperation 注解标注在方法上,用来描述一个方法的基本信息。
+ */
+ @ApiOperation(value = "修改用户", notes = "传入用户信息进行更新修改")
+ @PutMapping("/user")
+ public String updateUser(@RequestBody User user){
+ return user.toString();
+ }
+
+ /**
+ * @ApiImplicitParam 注解标注在方法上,用来描述方法的参数。其中 paramType 是指方法参数的类型,有如下可选值:
+ * path:参数获取方式为 @PathVariable
+ * query:参数获取方式为 @RequestParam
+ * header:参数获取方式为 @RequestHeader
+ * body
+ * form
+ */
+ @ApiOperation(value ="查询用户", notes = "根据 id 查询用户")
+ @ApiImplicitParam(paramType = "path", name = "id", value = "用户 id", required = true)
+ @GetMapping("/user/{id}")
+ public String getUserById(@PathVariable Integer id){
+ return "查找的用户id是:" + id;
+ }
+
+ /**
+ * 如果有多个参数,可以将多个参数的 @ApiImplicitParam 注解放到 @ApiImplicitParams 中
+ */
+ @ApiOperation(value = "新增用户", notes = "根据传入的用户名和密码添加一个新用户")
+ @ApiImplicitParams({
+ @ApiImplicitParam(paramType = "query", name = "username",
+ value = "用户名", required = true, defaultValue = "test"),
+ @ApiImplicitParam(paramType = "query", name = "password",
+ value = "密码", required = true, defaultValue = "123")
+ })
+ @PostMapping("/user")
+ public String addUser(@RequestParam String username, @RequestParam String password) {
+ return "新增用户:" + username + " " + password;
+ }
+
+ /**
+ * @ApiResponse 是对响应结果的描述。code 表示响应码,message 为相应的描述信息。如果有多个 @ApiResponse,则放在一个 @ApiResponses 中
+ */
+ @ApiOperation(value = "删除用户", notes = "根据 id 删除用户")
+ @ApiResponses({
+ @ApiResponse(code = 200, message = "删除成功!"),
+ @ApiResponse(code = 500, message = "删除失败!")
+ })
+ @DeleteMapping("/user/{id}")
+ public Integer deleteUserById(@PathVariable Integer id) {
+ return id;
+ }
+
+ /**
+ * @ApiIgnore 注解表示不对某个接口生成文档。
+ */
+ @ApiIgnore
+ @GetMapping("/user/test")
+ public String test() {
+ return "这是一个测试接口,不需要在api文档中显示。";
+ }
+}
+```
+
+
+
+#### 启动项目,访问Swagger-UI:http://127.0.0.1:8080/swagger-ui.html#/%E7%94%A8%E6%88%B7%E6%95%B0%E6%8D%AE%E6%8E%A5%E5%8F%A3

+# Spring的事务7种传播机制和隔离级别
+
+### Propagation(事务传播属性)
+Propagation 属性确定代理应该对那些方法增加事务行为,这样属性最重要的部分是传播行为:
+> - **PROPAGATION_REQUIRED** ----> 支持当前事务,如果当前没有事务,则新建一个事务,这是最常见的选择,也是 Spring 默认的一个事务传播行为;
+> - **PROPAGATION_SUPPORTS** ----> 支持当前事务,如果当前没有事务,则以非事务的方式执行;
+> - **PROPAGATION_MANDATORY** ----> 支持当前事务,如果当前没有事务,则抛出异常;
+> - **PROPAGATION_REQUIRES_NEW** ----> 新建事务,如果当前存在事务,把当前事务挂起;
+> - **PROPAGATION_NOT_SUPPORTED** ----> 以非事务的方式执行操作,如果当前存在事务,就把当前事务挂起;
+> - **PROPAGATION_NEVER** ----> 以非事务方式执行,如果当前存在事务,则抛出异常;
+> - **PROPAGATION_NESTED** ----> Nested的事务和它的父事务是相依的,它的提交是等它的父事务一块提交的;
+
+
+#### (一)PROPAGATION_REQUIRED
+注解用法比如:@Transactional(propagation = Propagation.REQUIRED)
+默认的 spring 事务传播级别,使用该级别的特点是:如果上下文中已经存在事务,那么就加入到事务中执行,如果当前上下文不存在事务,则新建事务执行
+在大多数业务场景下通常都能满足
+
+#### (二)PROPAGATION_SUPPORTS
+该传播级别的特点是:如果上下文存在事务,则支持事务加入事务,如果没有事务,则使用非事务的方式执行。所以说,并非所有的包在transactionTemplate.execute中的代码都会有事务支持。这个通常是用来处理那些非原子性的非核心业务逻辑操作。
+应用场景较少
+
+#### (三)PROPAGATION_MANDATORY
+该级别的事务要求上下文中必须要存在事务,否则就会抛出异常
+配置改方法的传播级别是有效的控制上下文调用代码遗漏添加事务控制的保证手段
+比如一段代码不能单独被调用执行,但是一旦被调用,就必须有事务包含的情况,就可以使用这个传播级别
+
+#### (四)PROPAGATION_REQUIRES_NEW
+该传播级别的特点是,每次都会新建一个事务,并且同时将上下文中的事务挂起,执行当前新建事务完成以后,上下文事务恢复再执行
+
+#### (五)PROPAGATION_NOT_SUPPORTED
+该传播属性不支持事务,该级别的特点就上下文中存在事务,则挂起事务,执行当前逻辑,结束后恢复上下文的事务
+好处:可以帮助我们把事务缩小范围。因为一个事务越大,它存在的风险也就越多。所以在处理事务过程中,要保证尽可能的缩小范围
+
+#### (六)PROPAGATION_NEVER
+不能在事务中运行,该事务传播级别要求中不能存在事务,一旦有事务,就抛出runtime异常,强制停止执行
+
+#### (七)PROPAGATION_NESTED
+理解Nested的关键是savepoint
+它与PROPAGATION_REQUIRES_NEW的区别是,PROPAGATION_REQUIRES_NEW另起一个事务,将会与它的父事务相互独立
+而Nested的事务和它的父事务是相依的,它的提交是要等和它的父事务一块提交的。也就是说,如果父事务最后回滚,它也要回滚的
