jersey+spring+mybatis+maven框架集成和實現簡單的crud

由於近期在學習jsm框架實現webservice 網上也是找了許多例子整合了很久才成功現在談談我的經驗希望對和我一樣的初學者有用可以少走一些彎路
開始：

entity層（pojo類）

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; 
//由於字數限時get和set自己實現 
public User(int id, String username, String sex, int age) { 
this.id = id; 
this.username = username; 
this.sex = sex; 
this.age = age; 
} 
public User() { 
} 
}

//注意要實現序列化和無參的構造方法

service層

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可以減少spring的耦合性

mapper層
//注意mapper層實際上是個接口用來讀取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);
}

實現層也就是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

需要新建一個source folder 名爲config
然後新建一個package名爲 MapperImpl
UserMapper.xml（在MapperImpl包裏面)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.eda.mapper.UserMapper">
    <!-- 作爲UserMapper接口的映射 -->
    <!-- 查詢 -->
    <select id="selectAllUser" parameterType="com.eda.entity.User"
        resultType="com.eda.entity.User">
        select id,username,sex,age
        from z_user
    </select>
    <!-- 根據ID查詢 -->
    <select id="selectUserbyID" parameterType="com.eda.entity.User"
        resultType="com.eda.entity.User">
        select id,username,sex,age
        from z_user
        where id = #{id}
    </select>
    <!-- 刪除 -->
    <delete id="deleteUserbyID" parameterType="com.eda.entity.User">
        delete
        from z_user
        where id = #{id}
    </delete>

</mapper>
