一、总体说明
本例运行演示了用 Jersey 构建 RESTful 服务中，如何集成 Spring3
二、环境
- 1.上文的项目RestDemo
- 2.Spring及其他相关的jar ,导入项目
三、配置
1.根目录下下创建 Spring 的配置文件applicationContext.xml； 配置如下： <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd"
> <!-- 激活那些已经在g容器里注册过的bean --> <context:annotation-config></context:annotation-config> <!-- 在容器中注入bean --> <bean id="UserServiceImpl" class="com.waylau.rest.service.impl.UserServiceImpl"/> <bean id="UserDaoImpl" class="com.waylau.rest.dao.impl.UserDaoImpl"/> </beans> 2.在com.waylau.rest.service和com.waylau.rest.service.impl下分别增加 UserService 和 UserServiceImpl。
UserService.java
package com.waylau.rest.service;
import java.util.List;
import com.waylau.rest.bean.User;
/**
* User Service 接口
* @author waylau.com
* 2014-7-25
*/ public interface UserService {
public User getUserById(String id);
public boolean deleteUserById(String id);
public boolean createUser(User user);
public boolean updateUser(User user);
public List<User> getAllUsers();
}
UserServiceImpl.java
package com.waylau.rest.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import com.waylau.rest.bean.User;
import com.waylau.rest.dao.impl.UserDaoImpl;
import com.waylau.rest.service.UserService;
/**
* User Service 接口实现
* @author waylau.com
* 2014-7-25
*/ public class UserServiceImpl implements UserService {
@Autowired private UserDaoImpl userDaoImpl;
public UserServiceImpl() {
// TODO Auto-generated constructor stub
}
@Override public User getUserById(String id) {
return userDaoImpl.getUserById(id);
}
@Override public boolean deleteUserById(String id) {
return userDaoImpl.deleteUserById(id);
}
@Override public boolean createUser(User user) {
return userDaoImpl.createUser(user);
}
@Override public boolean updateUser(User user) {
return userDaoImpl.updateUser(user);
}
@Override public List<User> getAllUsers() {
return userDaoImpl.getAllUsers();
}
}
3.修改 UserResource.java
package com.waylau.rest.resources;
import java.util.ArrayList;
import java.util.List;
import java.util.logging.Logger;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import org.springframework.beans.factory.annotation.Autowired;
import com.waylau.rest.bean.User;
import com.waylau.rest.service.impl.UserServiceImpl;
/**
* 用户资源
* @author waylau.com
* 2014-7-26
*/ @Path("/users")
public class UserResource {
private static final Logger LOGGER = Logger.getLogger(UserResource.class.getName());
@Autowired private UserServiceImpl userServiceImpl;
public UserResource() {
LOGGER.fine("UserResource()");
}
/**
* 增加
* @param user
*/ @POST @Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public void createUser(User user) {
userServiceImpl.createUser(user);
}
/**
* 删除
* @param id
*/ @DELETE @Path("{id}")
public void deleteUser(@PathParam("id")String id){
userServiceImpl.deleteUserById(id);
}
/**
* 修改
* @param user
*/ @PUT @Consumes(MediaType.APPLICATION_XML)
public void updateUser(User user){
userServiceImpl.updateUser(user);
}
/**
* 根据id查询
* @param id
* @return
*/ @GET @Path("{id}")
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public User getUserById(@PathParam("id") String id){
User u = userServiceImpl.getUserById(id);
return u;
}
/**
* 查询所有
* @return
*/ @GET @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public List<User> getAllUsers(){
List<User> users = new ArrayList<User>();
users = userServiceImpl.getAllUsers();
return users;
}
}
4.修改web.xml,插入
<module-name>RestDemo</module-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> 四、运行
1.先运行项目
2.运行UserClient.java测试，控制台输出如下
****增加用户addUser****
****查询所有getAllUsers****
[{"userId":"002","userName":"sdfs","age":"23"},{"userId":"003","userName":"sdfs","age":"23"},{"userId":"004","userName":"sdfs","age":"23"},{"userId":"005","userName":"sdfs","age":"23"},{"userId":"006","userName":"Susan","age":"21"},{"userId":"007","userName":"sdfs","age":"23"},{"userId":"ds","userName":"ds","age":"ds"}]
****修改用户updateUser****
****根据id查询用户****
006Susan33
****查询所有getAllUsers****
[{"userId":"002","userName":"sdfs","age":"23"},{"userId":"003","userName":"sdfs","age":"23"},{"userId":"004","userName":"sdfs","age":"23"},{"userId":"005","userName":"sdfs","age":"23"},{"userId":"006","userName":"Susan","age":"33"},{"userId":"007","userName":"sdfs","age":"23"},{"userId":"ds","userName":"ds","age":"ds"}]
****删除用户****
****查询所有getAllUsers****
[{"userId":"002","userName":"sdfs","age":"23"},{"userId":"003","userName":"sdfs","age":"23"},{"userId":"004","userName":"sdfs","age":"23"},{"userId":"005","userName":"sdfs","age":"23"},{"userId":"007","userName":"sdfs","age":"23"},{"userId":"ds","userName":"ds","age":"ds"}]
