jersey+spring+mybatis+maven框架集成和实现简单的crud

由于近期在学习jsm框架实现webservice 网上也是找了许多例子整合了很久才成功 现在谈谈我的经验 希望对和我一样的初学者有用 可以少走一些弯路
开始：

entity层（pojo类）

package com.eda.entity;import Java.io.Serializable; import javax.xml.bind.annotation.XmlRootElement;@XmlRootElement public class User implements Serializable { private int id; private String username; private String sex; private int age; //由于字数限时get和set自己实现 public User(int id, String username, String sex, int age) { this.id = id; this.username = username; this.sex = sex; this.age = age; } public User() { } }

//注意要实现序列化和无参的构造方法

service层

package com.eda.service;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.eda.entity.User; import com.eda.mapper.UserMapper;@Service public class UserService { @Resource private UserMapper userMapper; public List querryUsers() { return userMapper.selectAllUser(); } public User querryUsersbyID(int id) { return userMapper.selectUserbyID(id); } public void deleteUserbyID(int id){ userMapper.deleteUserbyID(id); }}

//使用@Resource可以减少spring的耦合性

mapper层
//注意mapper层实际上是个接口 用来读取mabits的配置
package com.eda.mapper;

import java.util.List;

import com.eda.entity.User;

public interface UserMapper {
List selectAllUser();
User selectUserbyID(int id);
void deleteUserbyID(int id);
}

实现层 也就是resourpackage com.eda.resource;

import java.io.UnsupportedEncodingException;
import java.util.List;

import javax.annotation.Resource;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.springframework.stereotype.Component;

import com.eda.entity.User;
import com.eda.service.UserService;
@Component
@Path(“User”)
public class UserResource {
@Resource
private UserService userService;
@GET
@Path(“getUser”)
@Produces(“application/json”)
public List getUsers() throws UnsupportedEncodingException
{
return userService.querryUsers();
}
@GET
@Path(“getUserbyID/{id}”)
@Produces(“application/json”)
public User getUserbyID(@PathParam(“id”)int id) throws UnsupportedEncodingException
{
return userService.querryUsersbyID(id);
}
@DELETE
@Path(“deleteUser/{id}”)
@Produces(MediaType.APPLICATION_JSON)
public void deleteUser(@PathParam(“id”)int id)
{
userService.deleteUserbyID(id);
}
}是配置文件

需要新建一个source folder 名为config
然后新建一个package名为 MapperImpl
UserMapper.xml（在MapperImpl包里面)
