springboot集成dubbo-spring-boot-starter 实现dubbo RPC远程调用

dubbo-spring-boot-starter Git源码地址： https://github.com/alibaba/dubbo-spring-boot-starter.git

创建一个SpringBoot Maven 项目(blog),且包含多个子项目（blog-api,blog-service,blog-web），在pom 文件中进行相关依赖：

blog父项目pom.xml

创建一个子项目blog-api:注意用于提供接口。（pom.xml 和相关代码如下）

接口定义如下：

package com.springboot.blog.api;

public interface RpcService {
public String rpc(String parame);
}

创建一个子项目blog-service：服务提供者。（注意涉及：dubbo和springboot的集成配置）

服务实现类和项目入口

package com.springboot.blog.support;

import com.alibaba.dubbo.config.annotation.Service;
import com.springboot.blog.api.RpcService;

@Service(version = "1.0.0", application = "${dubbo.application.id}", protocol = "${dubbo.protocol.id}", registry = "${dubbo.registry.id}")
public class RpcServiceImpl implements RpcService {

   @Override
   public String rpc(String parame) {
       // TODO Auto-generated method stub
       return "this params is :" + parame;
   }

}

package com.springboot.blog;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootService {

   public static void main(String[] args) {
       // TODO Auto-generated method stub
       SpringApplication.run(SpringBootService.class, args);
System.out.println("============= SpringBoot Service Start Success =============");
   }

}

创建一个子项目blog-web：服务消费者。（注意涉及：dubbo和springboot的集成配置）

pom.xml

       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-actuator</artifactId>

       </dependency>
   </dependencies>
</project>

application.properties（dubbo配置文件）

spring.application.name=blog-web
server.port=8081
#dubbo\u914D\u7F6E
dubbo.application.id=blog-web
dubbo.application.name=blog-web

dubbo.registry.id=my-registry
dubbo.registry.address=zookeeper://localhost:2181
management.port=8082

远程服务消费者和SpringBoot入口

package com.springboot.blog.web;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.dubbo.config.annotation.Reference;
import com.springboot.blog.api.RpcService;

@RestController
@RequestMapping("/dubbo")
public class RpcController {
   @Reference(version = "1.0.0")
   private RpcService service;

   @RequestMapping("/rpc")
public void rpc() {
       System.out.println(service.rpc("rpc 远程调用"));
}
}

package com.springboot.blog.web;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootWeb {

   public static void main(String[] args) {
       // TODO Auto-generated method stub
       SpringApplication.run(SpringBootWeb.class, args);
System.out.println("============= SpringBoot Web Start Success =============");
   }

}
