UserService

package com.cr.service;

import com.cr.entity.User;

import javax.ws.rs.*;
import java.util.List; //访问当前服务接口对应的路径
@Path("/userService")
@Produces("*/*")//支持任意类型
public interface UserService { @POST

User

//基于restful风格的webservice

public class User {

配置tomcat,启动服务

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(); }
