服务端

1. maven依赖
   服务端和消费端依赖相同

   <!-- dubbo -->
   <dependency>
       <groupId>com.alibaba.boot</groupId>
       <artifactId>dubbo-spring-boot-starter</artifactId>
       <version>0.2.0</version>
   </dependency>
   
   <!-- 基础依赖 -->
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   
   <!-- junit -->
   <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
   </dependency>
   

2. 服务端配置文件

   # base
   server.port=8002
   spring.application.name=sentinel-dubbo-user-provider
   
   # dubbo
   ## dubbo.application.name：注册到dubbo的服务名称
   ## dubbo.registry.address：dubbo注册地址
   ## dubbo.registry.protocol：dubbo注册协议
   ## dubbo.scan.base-packages：实现扫包范围
   ## dubbo.protocol.port：暴露到dubbo的端口
   dubbo.application.name=sentinel-dubbo-user-provider
   dubbo.registry.address=127.0.0.1:7001
   dubbo.registry.protocol=zookeeper
   dubbo.scan.base-packages=com.demo
   dubbo.protocol.port=28002
   

3. @Service注解为dubbo注解
   import com.alibaba.dubbo.config.annotation.Service;
4. 启动类注解

   @SpringBootApplication(scanBasePackages = "com.demo.*")
   @EnableDubbo
   

消费端

1. maven依赖
   服务端和消费端依赖相同

   <!-- dubbo -->
   <dependency>
       <groupId>com.alibaba.boot</groupId>
       <artifactId>dubbo-spring-boot-starter</artifactId>
       <version>0.2.0</version>
   </dependency>
   
   <!-- 基础依赖 -->
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   
   <!-- junit -->
   <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
   </dependency>
   

2. 配置文件
   服务端和消费端配置不同

   # base
   server.port=8003
   spring.application.name=sentinel-client
   
   # dubbo
   ## dubbo.application.name：注册到dubbo的服务名称
   ## dubbo.registry.address：dubbo注册地址
   ## dubbo.registry.protocol：dubbo注册协议
   ## dubbo.scan.base-packages：实现扫包范围
   ## dubbo.protocol.port：暴露到dubbo的端口
   dubbo.application.name=sentinel-client
   dubbo.registry.address=127.0.0.1:7001
   dubbo.registry.protocol=zookeeper
   dubbo.consumer.timeout=5000
   
   

3. 调用服务端

   @Reference
   private UserServiceApi userServiceApi;
   

4. 启动类注解

   @SpringBootApplication
   @EnableDubbo
   

以上，就是全部配置。
