//  访问当前服务接口对应的路径

}

启动测试类：

public class Server {
    public static void main(String[] args) {
        // 创建发布服务的工厂
        JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();

        // 设置服务地址
        factory.setAddress("http://localhost:8001/ws/");

        // 设置服务类
        factory.setServiceBean(new UserServiceImpl());

        // 添加日志输入输出拦截器
        factory.getInInterceptors().add(new LoggingInInterceptor());
        factory.getOutInterceptors().add(new LoggingOutInterceptor());

        // 发布服务
        factory.create();

        System.out.println("发布服务成功，端口8001");
    }
}

和服务端一样，这里就不贴出来了。

测试类：

@Test
    public void testSave(){
        User user = new User();
        user.setId(100);
        user.setUsername("Jerry");
        user.setCity("gz");
        // 通过WebClient对象远程调用服务端
        WebClient
                    .create("http://localhost:8001/ws/userService/user")
                    .type(MediaType.APPLICATION_JSON)  // 指定请求的数据格式为json
                    .post(user);
    }

@Test
    public void testGet(){
        // 查询一个
        User user =
            WebClient
                    .create("http://localhost:8001/ws/userService/user/1")
                   .accept(MediaType.APPLICATION_JSON)
                    .get(User.class);
        System.out.println(user);
    }

@Test
    public void testUpdate(){
        User user = new User();
        user.setId(100);
        user.setUsername("Jerry");
        user.setCity("gz");
        WebClient
                .create("http://localhost:8001/ws/userService/user")
                .accept(MediaType.APPLICATION_XML)
                .put(user);
        System.out.println(user);
    }
