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
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
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）
pom.xml
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

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
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
application.properties（dubbo配置文件）
spring.application.name=blog-web
server.port=8081

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 =============");
}
}
