SpringBoot整合dubbo,使用zookeeper作为注册中心

SpringBoot整合dubbo,使用zookeeper作为注册中心

---

1. 安装zookeeper,从官网下载并配置zoo.cfg配置文件，然后启动

2. 创建工程dubboServer用于注册服务

   pom.xml

   
           
               org.springframework.boot
               spring-boot-starter
           
   ​
           
               org.springframework.boot
               spring-boot-starter-test
               test
           
   ​
           
               com.alibaba.boot
               dubbo-spring-boot-starter
               0.1.1
           
       

   application.properties

   # Spring boot application
   spring.application.name = dubbo-provider-demo
   server.port = 9090
   management.port = 9091
   ​
   # Service version
   demo.service.version = 1.0.0
   ​
   # Base packages to scan Dubbo Components (e.g @Service , @Reference)
   dubbo.scan.basePackages  = com.cc
   ​
   # Dubbo Config properties
   ## ApplicationConfig Bean
   dubbo.application.id = dubbo-provider-demo
   dubbo.application.name = dubbo-provider-demo
   ​
   ## ProtocolConfig Bean
   dubbo.protocol.id = dubbo
   dubbo.protocol.name = dubbo
   dubbo.protocol.port = 12345
   ​
   ## RegistryConfig Bean
   dubbo.registry.id = zdubbo
   dubbo.registry.address = zookeeper://127.0.0.1:2181

   创建接口，用于注册

   package com.cc.dubboServer.dubboServer;
   ​
   public interface IDubboServer {
   ​
       String helloWord(String str);
   }

   实现接口

   package com.cc.dubboServer.dubboServer;
   ​
   import com.alibaba.dubbo.config.annotation.Service;
   import org.springframework.stereotype.Component;
   ​
   @Service(version = "${demo.service.version}")
   @Component
   public class DubboServerimpl implements IDubboServer {
       @Override
       public String helloWord(String str) {
           return str + "调用了服务";
       }
   }

   1. 创建dubboClient工程调用服务

      application.properties

      # Spring boot application
      spring.application.name = dubbo-provider-demo
      server.port = 9090
      management.port = 9091
      ​
      # Service version
      demo.service.version = 1.0.0
      ​
      # Base packages to scan Dubbo Components (e.g @Service , @Reference)
      dubbo.scan.basePackages  = com.cc
      ​
      # Dubbo Config properties
      ## ApplicationConfig Bean
      dubbo.application.id = dubbo-consume-demo
      dubbo.application.name = dubbo-consume-demo
      ​
      ​
      ## RegistryConfig Bean
      dubbo.registry.id = zdubbo
      dubbo.registry.address = zookeeper://127.0.0.1:2181

      创建与服务提供方相同的接口

      package com.cc.dubboServer.dubboServer;
      ​
      public interface IDubboServer {
      ​
          String helloWord(String str);
      }

      单元测试，调用

      package com.cc.dubboClient;
      ​
      import com.alibaba.dubbo.config.annotation.Reference;
      import com.cc.dubboServer.dubboServer.IDubboServer;
      import org.junit.Test;
      import org.junit.runner.RunWith;
      import org.springframework.boot.test.context.SpringBootTest;
      import org.springframework.test.context.junit4.SpringRunner;
      ​
      @RunWith(SpringRunner.class)
      @SpringBootTest
      public class DubboClientApplicationTests {
      ​
          @Reference(version = "${demo.service.version}")
          private IDubboServer dubboServer;
      ​
          @Test
          public void contextLoads() {
              System.out.println(dubboServer.helloWord("二傻子"));
          }
      ​
      }
