SpringBoot 配合Dubbo 详细实现代码

使用Spring Boot 与Dubbo集成.这里使用的是XML而不是注解

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

一、提供端

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"

<!-- 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);
}

}
2、pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

3、dubbo-consumer.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"

http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

<!-- 消费方应用名 -->
<dubbo:application name="consumer" />

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

<!-- 引用ComputeService服务-->
<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));
}
