springboot-dubbo整合

一、创建springboot-dubbo-provider maven springboot工程 引入一下pom依赖

    
		org.springframework.boot
		spring-boot-starter-parent
		1.5.8.RELEASE
	
    
		UTF-8
		UTF-8
		1.8
	
	
		
			com.alibaba.boot
			dubbo-spring-boot-starter
			0.1.0
		
		
		
			com.101tec
			zkclient
			0.2
		
		
			org.springframework.boot
			spring-boot-starter-web
		
		
			org.springframework.boot
			spring-boot-starter-test
			test
		

二、编写application.properties/.yml文件

dubbo.application.name=springboot-dubbo-provider
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.scan.base-packages=com.xxx.service
server.port=8888

三、编写启动文件Application.java

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

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

四、编写provider service接口及其实现类

public interface ProvideService {
    public String sayHello(String name);
}

import com.alibaba.dubbo.config.annotation.Service;
import com.camelot.service.ProvideService;

import org.springframework.stereotype.Component;

@Component
@Service//该注解为dubbo的@service注解
public class ProvideServiceImpl implements ProvideService {

    public String sayHello(String name) {
        return "-------hello" + name;
    }

}

五、启动zookeeper和dubbo-admin-2.8.4，发现提供者可以运行了

六、创建dubbo的消费者maven springboot工程（依赖和dubbo提供者相同）

编写application.properties/.yml文件

dubbo.application.name=springboot-dubbo-consumer
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.scan.base-packages=com.xxx.service
server.port=8888

七、编写consumer service接口及其实现类

public interface ConsumerService {
    public String sayHello(String name);
}

import com.alibaba.dubbo.config.annotation.Reference;
import com.camelot.service.ProvideService;

import org.springframework.stereotype.Service;

@Service//该注解为spring的@service注解

public class ConsumerServiceImpl {

@Reference//dubbo注解 private ProvideService provideService; public String sayHello(String name) { return provideService.sayHello(name); }

此外，还需要引入提供者的service（要求包名相同）

@Service
public interface ProvideService {
    public String sayHello(String name);
}

八、编写consumer的测试类

import com.alibaba.dubbo.config.annotation.Reference;
import com.camelot.service.ProvideService;

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 ApplicationTest {
    @Reference
    private ProvideService provideService;

    @Test
    public void getMessage() {
        String sayHello = provideService.sayHello(" John-------");
        System.out.println(sayHello);
    }
}

九、运行consumer工程，发现提供者消费者都在dubbo-admin上显示了
