demo 采用的是spring boot 项目

---

• mven 依赖

<!-- Spring Boot Dubbo 依赖 --><dependency>    <groupId>io.dubbo.springboot</groupId>    <artifactId>spring-boot-starter-dubbo</artifactId>    <version>1.0.0</version></dependency>

• 服务提供者配置

## Dubbo 服务提供者配置spring.dubbo.application.name=providerspring.dubbo.registry.address=zookeeper://127.0.0.1:2181spring.dubbo.protocol.name=dubbospring.dubbo.protocol.port=20880spring.dubbo.scan=com.ldh.dubbo.service

服务提供者使用@Service注解（dubbo包下的），标记要注册的方法

@Servicepublic class UserServiceImpl implements UserService {    @Override    public String login() {        return "登录成功" + new Date();    }}

服务消费者方

配置文件

## 避免和 server 工程端口冲突server.port=8081## Dubbo 服务消费者配置spring.dubbo.application.name=consumerspring.dubbo.registry.address=zookeeper://127.0.0.1:2181spring.dubbo.scan=com.ldh.dubbo.service

服务消费者使用@Reference注解

@Componentpublic class MovieServiceImp implements MovieService {    @Reference    private UserService userService;    public void show(){        String res = userService.login();        System.out.println(res);    }}
