Spring Boot 集成Dubbo

更多干货

 

使用Spring Boot 与Dubbo集成.这里使用的是XML而不是注解

代码地址：https://github.com/csy512889371/learndemo/tree/master/ctoedu-springboot-dubbo

  • ctoedu-springboot-dubbo-consumer 消费端
  • ctoedu-springboot-dubbo-provider 提供端

更多干货

 

一、提供端

1、pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>

</project>

2、Application.java

package cn.ctoedu;

import org.apache.log4j.Logger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ImportResource;

import java.util.concurrent.CountDownLatch;

@SpringBootApplication
@ImportResource({"classpath:dubbo-provider.xml"})
public class Application {

	private static final Logger logger = Logger.getLogger(Application.class);

	@Bean
	public CountDownLatch closeLatch() {
		return new CountDownLatch(1);
	}

	public static void main(String[] args) throws InterruptedException {
		ApplicationContext ctx = SpringApplication.run(Application.class, args);
//		logger.info("项目启动!");
//		CountDownLatch closeLatch = ctx.getBean(CountDownLatch.class);
//		closeLatch.await();
	}

}

3、ComputeService.java

package cn.ctoedu.service.impl;

import cn.ctoedu.service.ComputeService;


public class ComputeServiceImpl implements ComputeService {

    public Integer add(int a, int b) {
        return a + b;
    }

}

4、application.yml

server:
  port: 8010
#ZooKeeper
dubbo:
  registry:
    address: localhost:2181
logging:
  level:
    root: INFO

5、dubbo-provider.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="compute-service"  />

    <!-- 注册中心服务地址 -->
    <dubbo:registry id="zookeeper" protocol="zookeeper" address="${dubbo.registry.address}" />

    <!-- 用dubbo协议在30001 -->
    <dubbo:protocol name="dubbo" port="30001" />

    <!-- 声明需要暴露的服务接口 -->
    <dubbo:service interface="cn.ctoedu.service.ComputeService" ref="computeService"
                   version="1.0" registry="zookeeper"/>

    <!-- 具体服务接口的实现 -->
    <bean id="computeService" class="cn.ctoedu.service.impl.ComputeServiceImpl" />

</beans>

二、消费端

1、application.java

package cn.ctoedu;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ImportResource({"classpath:dubbo-consumer.xml"})
public class Application {

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

}

    <dubbo:reference id="computeService" interface="cn.ctoedu.service.ComputeService"
                     check="false" version="1.0" url="" registry="zookeeper" protocol="dubbo" timeout="15000"/>

</beans>

4、ApplicationTests 测试类

package cn.ctoedu;

import cn.ctoedu.service.ComputeService;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;


@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
public class ApplicationTests {

	@Autowired
	ComputeService computeService;

	@Test
	public void testAdd() throws Exception {
		System.out.println("cn.ctoedu: Dubbo消费结果为：。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。"+computeService.add(100, 200));
		Assert.assertEquals("compute-service:add", new Integer(3), computeService.add(1, 2));
		//Assert.assertEquals("compute-service:add", new Integer(5), computeService.add(1, 2));
	}
