Dubbo+Zookeeper的RPC远程调用框架demo _Dubbo

Dubbo是阿里巴巴公司开源的一个高性能优秀的服务框架，使得应用可通过高性能的 RPC 实现服务的输出和输入功能，可以和Spring框架无缝集成。
Dubbo是一款高性能、轻量级的开源JAVA RPC框架，它提供了三大核心能力：面向接口的远程方法调用，智能容错和负载均衡，以及服务自动注册和发现。

provider：暴露服务的服务提供方
consumer：调用远程服务的服务消费方
registry：服务注册于发现的注册中心
monitor：统计服务调用次数和调用时间的监控中心
container：服务运行容器

1、UserInfo
为什么要实现Serializable接口？当我们需要把对象的状态信息通过网络进行传输，或者需要将对象的状态信息持久化，以便将来使用时都需要把对象进行序列化。
@Datapublic class UserInfo implements Serializable { private String account; private String password;}2、UserService
public interface UserService { // 定义用户登录的api UserInfo login(UserInfo user);}3、UserServiceImpl
@Component@Service(interfaceClass = UserService.class)public class UserServiceImpl implements UserService { public UserInfo login(UserInfo user) { UserInfo reUser = new UserInfo(); reUser.setAccount("登录的账号为:"+user.getAccount()); reUser.setPassword("登录的密码为:"+user.getPassword()); return reUser; }}4、DubboProviderApplication
@SpringBootApplication@EnableDubboConfiguration // 启用dubbo自动配置public class DubboProviderApplication { public static void main(String[] args) { SpringApplication.run(DubboProviderApplication.class, args); }}5、pom.xml
