配置tomcat，启动服务

2、客户端的实现

1、工程目录

3、类

package com.cr.entity;

import javax.xml.bind.annotation.XmlRootElement;

//基于restful风格的webservice
//客户端与服务的之间通讯可以传到xml、json

//该注解指定对象序列化为xml或者json数据时根节点的名称
//xml：  <User><id></id></User>
//json:效率更高   {"User":"",pwd:""}

@XmlRootElement(name = "User")
public class User {
    private  String name;
    private  String  pwd;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

    public User() {
    }

    public User(String name, String pwd) {
        this.name = name;
        this.pwd = pwd;
    }
}

测试：

   @Test
    public void save(){
        //远程调用服务端
        WebClient.
                create("http://localhost:8082/cr/userService/userService/user").
                type("application/json").
                post(new User("qq",""));
    }

查询：

    //查询
    @Test
    public void find(){
        WebClient.create("http://localhost:8082/cr/userService/userService/user").get();

    }
