Smart Framework

简介

1. 它是一款轻量级 Java Web 框架

2. 它使应用充分做到"前后端分离"

3. 它可提高应用程序的开发效率

入门

1. 创建一个 Maven Web 工程

smart-sample/
 ┗ src/
  ┗ main/
   ┗ java/
   ┗ resources/
   ┗ webapp/
 ┗ pom.xml

org/
 ┗ smart4j/
  ┗ sample/
   ┗ action/
   ┗ entity/
   ┗ service/

2. 配置 Maven 依赖

<dependency>
 <groupId>org.smart4j</groupId>
 <artifactId>smart-framework</artifactId>
 <version>[版本号]</version>
</dependency>

3. 编写 Smart 配置

smart.framework.app.base_package=org.smart4j.sample
smart.framework.app.home_page=/users
smart.framework.jdbc.driver=com.mysql.jdbc.Driver
smart.framework.jdbc.url=jdbc:mysql://localhost:3306/smart-sample
smart.framework.jdbc.username=root
smart.framework.jdbc.password=root

4. 编写 Entity 类

package org.smart4j.sample.entity;
import org.smart4j.framework.orm.annotation.Entity;
@Entity
public class User {
 private long id;
 private String username;
 private String password;
 // getter/setter
}

5. 编写 Service 接口及其实现

package org.smart4j.sample.service;
import java.util.List;
import java.util.Map;
import org.smart4j.sample.entity.User;
public interface UserService {
 List<User> findUserList();
 User findUser(long id);
 boolean saveUser(Map<String, Object> fieldMap);
 boolean updateUser(long id, Map<String, Object> fieldMap);
 boolean deleteUser(long id);
}

package org.smart4j.sample.service.impl;
import java.util.List;
import java.util.Map;
import org.smart4j.framework.orm.DataSet;
import org.smart4j.framework.tx.annotation.Service;
import org.smart4j.framework.tx.annotation.Transaction;
import org.smart4j.sample.entity.User;
import org.smart4j.sample.service.UserService;
@Service
public class UserServiceImpl implements UserService {
 @Override
 public List<User> findUserList() {
 return DataSet.selectList(User.class);
 }
 @Override
 public User findUser(long id) {
 return DataSet.select(User.class, "id = ?", id);
 }
 @Override
 @Transaction
 public boolean saveUser(Map<String, Object> fieldMap) {
 return DataSet.insert(User.class, fieldMap);
 }
 @Override
 @Transaction
 public boolean updateUser(long id, Map<String, Object> fieldMap) {
 return DataSet.update(User.class, fieldMap, "id = ?", id);
 }
 @Override
 @Transaction
 public boolean deleteUser(long id) {
 return DataSet.delete(User.class, "id = ?", id);
 }
}

5. 编写 Action 类

package org.smart4j.sample.action;
import java.util.List;
import java.util.Map;
import org.smart4j.framework.ioc.annotation.Inject;
import org.smart4j.framework.mvc.DataContext;
import org.smart4j.framework.mvc.annotation.Action;
import org.smart4j.framework.mvc.annotation.Request;
import org.smart4j.framework.mvc.bean.Params;
import org.smart4j.framework.mvc.bean.Result;
import org.smart4j.framework.mvc.bean.View;
import org.smart4j.sample.entity.User;
import org.smart4j.sample.service.UserService;
@Action
public class UserAction {
 @Inject
 private UserService userService;
 @Request.Get("/users")
 public View index() {
 List<User> userList = userService.findUserList();
 DataContext.Request.put("userList", userList);
 return new View("user.jsp");
 }
 @Request.Get("/user")
 public View create() {
 return new View("user_create.jsp");
 }
 @Request.Post("/user")
 public Result save(Params params) {
 Map<String, Object> fieldMap = params.getFieldMap();
 boolean result = userService.saveUser(fieldMap);
 return new Result(result);
 }
 @Request.Get("/user/{id}")
 public View edit(long id) {
 User user = userService.findUser(id);
 DataContext.Request.put("user", user);
 return new View("user_edit.jsp");
 }
 @Request.Put("/user/{id}")
 public Result update(long id, Params params) {
 Map<String, Object> fieldMap = params.getFieldMap();
 boolean result = userService.updateUser(id, fieldMap);
 return new Result(result);
 }
 @Request.Delete("/user/{id}")
 public Result delete(long id) {
 boolean result = userService.deleteUser(id);
 return new Result(result);
 }
}
