+### 系统初始化器解析
+
+#### 1、ApplicationContextInitializer作用
+
+```java
+/**
+ * Callback interface for initializing a Spring {@link ConfigurableApplicationContext}
+ * prior to being {@linkplain ConfigurableApplicationContext#refresh() refreshed}.
+ *
+ * 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.
+ *
+ *
{@code ApplicationContextInitializer} processors are encouraged to detect
+ * whether Spring's {@link org.springframework.core.Ordered Ordered} interface has been
+ * implemented or if the @{@link org.springframework.core.annotation.Order Order}
+ * annotation is present and to sort instances accordingly if so prior to invocation.
+ *
+ * @author Chris Beams
+ * @since 3.1
+ * @param the application context type
+ * @see org.springframework.web.context.ContextLoader#customizeContext
+ * @see org.springframework.web.context.ContextLoader#CONTEXT_INITIALIZER_CLASSES_PARAM
+ * @see org.springframework.web.servlet.FrameworkServlet#setContextInitializerClasses
+ * @see org.springframework.web.servlet.FrameworkServlet#applyInitializers
+ */
+public interface ApplicationContextInitializer {
+
+ /**
+ * Initialize the given application context.
+ * @param applicationContext the application to configure
+ */
+ void initialize(C applicationContext);
+}
+
+```
+
+- 上下文刷新即refersh方法前调用;
+- 用来编码设置一些属性变量,通常用在web环境中;
+- 可以通过order接口进行排序;
+
+
+
+#### 2、ApplicationContextInitializer调用点,通过SpringFactoriesLoder中的this.initializers进行初始化
+
+image-20210802174243992
+
+- 步骤一:在刷新上下文前,调用prepareContext#()准备上下文的方法
+
+```java
+public ConfigurableApplicationContext run(String... args) {
+ StopWatch stopWatch = new StopWatch();
+ stopWatch.start();
+ ConfigurableApplicationContext context = null;
+ Collection exceptionReporters = new ArrayList();
+ configureHeadlessProperty();
+ SpringApplicationRunListeners listeners = getRunListeners(args);
+ listeners.starting();
+ try {
+ ApplicationArguments applicationArguments = new DefaultApplicationArguments(args);
+ ConfigurableEnvironment environment = prepareEnvironment(listeners, applicationArguments);
+ configureIgnoreBeanInfo(environment);
+ Banner printedBanner = printBanner(environment);
+ context = createApplicationContext();
+ exceptionReporters = getSpringFactoriesInstances(SpringBootExceptionReporter.class,
+ new Class[] { ConfigurableApplicationContext.class }, context);
+ // 准备上下文
+ prepareContext(context, environment, listeners, applicationArguments, printedBanner);
+ // 刷新上下文
+ refreshContext(context);
+ afterRefresh(context, applicationArguments);
+ stopWatch.stop();
+ if (this.logStartupInfo) {
+ new StartupInfoLogger(this.mainApplicationClass).logStarted(getApplicationLog(), stopWatch);
+ }
+ listeners.started(context);
+ callRunners(context, applicationArguments);
+ }
+ catch (Throwable ex) {
+ handleRunFailure(context, ex, exceptionReporters, listeners);
+ throw new IllegalStateException(ex);
+ }
+
+ try {
+ listeners.running(context);
+ }
+ catch (Throwable ex) {
+ handleRunFailure(context, ex, exceptionReporters, null);
+ throw new IllegalStateException(ex);
+ }
+ return context;
+ }
+```
+
+- 步骤二:调用初始化器 applyInitializers(context) 方法
+
+```java
+ private void prepareContext(ConfigurableApplicationContext context, ConfigurableEnvironment environment,
+ SpringApplicationRunListeners listeners, ApplicationArguments applicationArguments, Banner printedBanner) {
+ context.setEnvironment(environment);
+ postProcessApplicationContext(context);
+ // 调用初始化器方法
+ applyInitializers(context);
+ listeners.contextPrepared(context);
+ if (this.logStartupInfo) {
+ logStartupInfo(context.getParent() == null);
+ logStartupProfileInfo(context);
+ }
+ // Add boot specific singleton beans
+ ConfigurableListableBeanFactory beanFactory = context.getBeanFactory();
+ beanFactory.registerSingleton("springApplicationArguments", applicationArguments);
+ if (printedBanner != null) {
+ beanFactory.registerSingleton("springBootBanner", printedBanner);
+ }
+ if (beanFactory instanceof DefaultListableBeanFactory) {
+ ((DefaultListableBeanFactory) beanFactory)
+ .setAllowBeanDefinitionOverriding(this.allowBeanDefinitionOverriding);
+ }
+ // Load the sources
+ Set sources = getAllSources();
+ Assert.notEmpty(sources, "Sources must not be empty");
+ load(context, sources.toArray(new Object[0]));
+ listeners.contextLoaded(context);
+ }
+```
+
+- 步骤三:系统初始化器的具体实现,调用 ApplicationContextInitializer.initialize() 方法
+
+```java
+ @SuppressWarnings({ "rawtypes", "unchecked" })
+ protected void applyInitializers(ConfigurableApplicationContext context) {
+ // getInitializers() 方法,从this.initializers 成员中,获取初始化器的实现
+ for (ApplicationContextInitializer initializer : getInitializers()) {
+ // 判断初始化器的实现类,是否实现了ApplicationContextInitializer接口类
+ Class requiredType = GenericTypeResolver.resolveTypeArgument(initializer.getClass(),
+ ApplicationContextInitializer.class);
+ Assert.isInstanceOf(requiredType, context, "Unable to call initializer.");
+ // 调用初始化器实现类中的 initialize#() 方法,进行初始化
+ initializer.initialize(context);
+ }
+ }
+```
+
+
+
+#### 3、添加系统初始化器 this.initializers 成员的两种方式
+
+- 第一种:定义在spring.factories文件中,通过SpringFactoriesLoader发现与注册
+
+ ```java
+ SpringBoot框架中从类路径jar包中读取特定的文件(META-INF/spring.factories)实现扩展类的载入
+ 最终调用SpringApplication.addInitializers#()方法添加到this.initializers成员中
+ ```
+
+
+
+- 第二种:通过SpringApplication.addInitializers#() 方法手动添加到系统初始化器中
+
+ ```java
+ 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();
+ }
+ ```
+
+
+
+- 第三种:在application.properties 配置文件中定义环境变量,通过DelegatingApplicationContextInitializer 发现与注册
+
+ - 步骤一:DelegatingApplicationContextInitializer 在Spring框架中,会被SpringFactoriesLoader 自动加载,且优先级最高 order = 0
+
+ ```java
+ # 在spring.factories配置文件中
+ # Application Context Initializers
+ org.springframework.boot.context.config.DelegatingApplicationContextInitializer,\
+ ```
+
+ - 步骤二:通过DelegatingApplicationContextInitializer 中的 initialize#() 方法,获取ApplicationContextInitializer.class的实现
+
+ ```java
+ private static final String PROPERTY_NAME = "context.initializer.classes";
+
+ private int order = 0;
+
+ @Override
+ public void initialize(ConfigurableApplicationContext context) {
+ // 获取application.properties配置中的 context.initializer.classes 属性
+ ConfigurableEnvironment environment = context.getEnvironment();
+ // 获取所有 ApplicationContextInitializer.class 接口的实现类
+ List> initializerClasses = getInitializerClasses(environment);
+ if (!initializerClasses.isEmpty()) {
+ // 初始化系统初始化器
+ applyInitializerClasses(context, initializerClasses);
+ }
+ }
+ ```
+
+

+## 监听器
+
+### 1、监听器模式介绍
+
+image-20210803144505140
+
+
+
+- 系统消息由广播器(Multicaster)发布出去,发布的内容统称为事件(Event),对关键事件产生订阅的是监听器(Listener);
+
+
+
+### 2、自定义事件-创建事件
+
+- 创建天气事件抽象类
+
+ ```java
+ // 天气事件抽象类
+ public abstract class WeatherEvent {
+ // 获取当前天气的事件
+ public abstract String getWeather();
+ }
+ ```
+
+- 创建下雨事件实现类
+
+ ```java
+ // 下雨事件
+ public class RainEvent extends WeatherEvent {
+ @Override
+ public String getWeather() {
+ return "rain";
+ }
+ }
+ ```
+
+- 创建下雪事件实现类
+
+ ```java
+ // 下雪事件
+ public class SnowEvent extends WeatherEvent {
+ @Override
+ public String getWeather() {
+ return "snow";
+ }
+ }
+ ```
+
+
+
+#### 3、自定义事件监听器-创建监听器
+
+- 创建天气事件监听器接口类
+
+ ```java
+ // 天气监听器
+ public interface WeatherListener {
+ // 监听天气事件
+ void onWeatherEvent(WeatherEvent event);
+ }
+ ```
+
+- 创建下雨事件监听器实现类
+
+ ```java
+ // 下雨监听器
+ public class RainListener implements WeatherListener {
+ @Override
+ public void onWeatherEvent(WeatherEvent event) {
+ if (event instanceof RainEvent) {
+ System.out.println("rain event ..." + event.getWeather());
+ }
+ }
+ }
+ ```
+
+- 创建下雪事件监听器实现类
+
+ ```java
+ // 下雪监听器
+ public class SnowListener implements WeatherListener {
+ @Override
+ public void onWeatherEvent(WeatherEvent event) {
+ if (event instanceof SnowEvent) {
+ System.out.println("snow event.." + event.getWeather());
+ }
+ }
+ }
+ ```
+
+
+
+#### 4、自定义事件广播器-创建事件广播器
+
+- 创建事件广播器接口
+
+ ```java
+ // 事件广播器
+ public interface EventMulticaster {
+ // 广播事件
+ void multicastEvent(WeatherEvent event);
+ // 添加监听器
+ void addListener(WeatherListener listener);
+ // 删除监听器
+ void removeListener(WeatherListener listener);
+ }
+
+- 创建事件广播器的抽象类
+
+ ```java
+
+ // 抽象的事件广播器
+ public abstract class AbstractEventMulticaster implements EventMulticaster {
+ // 事件监听器列表
+ private List listenerList = new CopyOnWriteArrayList();
+
+ @Override
+ public void multicastEvent(WeatherEvent event) {
+ // 广播所有事件监听器
+ listenerList.forEach(listener -> {
+ // 触发前-模版方法
+ doStart();
+ // 触发机制
+ listener.onWeatherEvent(event);
+ // 触发后-模版方法
+ doEnd();
+ });
+ }
+
+ // 添加事件监听器
+ @Override
+ public void addListener(WeatherListener listener) {
+ listenerList.add(listener);
+ }
+
+ // 删除事件监听器
+ @Override
+ public void removeListener(WeatherListener listener) {
+ listenerList.remove(listener);
+ }
+
+ // 模版方法
+ abstract void doStart();
+ abstract void doEnd();
+ }
+ ```
+
+- 创建事件广播器的实现类
+
+ ```java
+ // 天气事件广播器
+ public class WeatherEventMulticaster extends AbstractEventMulticaster {
+ @Override
+ public void doStart() {
+ System.out.println("multicaster event begin ...");
+ }
+ @Override
+ public void doEnd() {
+ System.out.println("multicaster evnet end ....");
+ }
+ }
+ ```
+
+
+
+#### 5、测试
+
+```java
+public class Test {
+
+ public static void main(String[] args) {
+ // 创建事件广播器
+ WeatherEventMulticaster multicaster = new WeatherEventMulticaster();
+
+ // 添加事件监听器
+ WeatherListener listener1 = new SnowListener();
+ WeatherListener listener2 = new RainListener();
+ multicaster.addListener(listener1);
+ multicaster.addListener(listener2);
+
+ // 广播事件
+ WeatherEvent event1 = new RainEvent();
+ WeatherEvent event2 = new SnowEvent();
+ multicaster.multicastEvent(event1);
+ multicaster.multicastEvent(event2);
+ }
+}

+### 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
