//创建工程名 cnse-customer-user

导入jar包

//工程结构

//spring 文件配置

//service接口

package com.cnse.provider.user.service;import java.util.List;import com.cnse.provider.user.service.po.User;/** * @author Administrator *  */public interface UserService {//检测用户登录的接口public String checkLoginUser(String username,String password);//获取用户列表的接口public List<User>getUsers();}

//service空实现以为服务端不会告诉你具体的实现但自己要做一个空实现

package com.cnse.provider.user.service.impl;import java.util.List;import com.cnse.provider.user.service.UserService;import com.cnse.provider.user.service.po.User;/** * @author Administrator * 服务端是不会给客户端具体的实现方法的 * 所有要做一个空实现 调用的时候都是调用的服务端的 */public class UserServiceImpl implements UserService {@Overridepublic String checkLoginUser(String username, String password) {return null;}@Overridepublic List<User> getUsers() {return null;}}

//dubbo调用xml配置文件

//log日志文件

//webxml

//调用服务接口的测试类

package com.cnse.customer.user.test;import java.util.List;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.cnse.provider.user.service.UserService;import com.cnse.provider.user.service.po.User;/** * @author Administrator * */public class UserConsumer {public static void main(String[] args) throws Exception {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "spring-context-customer.xml" });context.start();UserService userService = (UserService) context.getBean("userService");String respStr = userService.checkLoginUser("admin","123456");System.out.println("调用登录服务的接口__respStr__:"+respStr);List<User>list = userService.getUsers();if (list != null && list.size() > 0) {for (int i = 0; i < list.size(); i++) {System.out.println("调用用户列表服务的接口__respStr__:"+list.get(i));}}System.in.read();}}
