1、docker安装zookeeper
sudo docker pull zookeeper:3.4.11
sudo docker run --name zoopker01 -p 2181:2181 --restart always -d zookeeper:3.4.11
sudo docker ps -a
2、新建一个空项目,再分别新建两个module,一个是provider-ticket,一个是consumer-user
建好之后建立如下目录及文件:
(1) 首先分别将相关依赖导入到provider-ticket和consumer-user的pom.xml中
<!--引入dubbo--> <dependency> <groupId>com.alibaba.boot</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>0.1.0</version> </dependency> <!--引入zookeeper--> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency>
(2)配置相关信息
在provider-ticker中application.properties
#提供者名称 dubbo.application.name=provider-ticket #注册中心地址 dubbo.registry.address=zookeeper://192.168.124.22:2181 #将哪个包的服务发送出去 dubbo.scan.base-packages=com.gong.com.gong.providerticket.service
在consumer-user中application.properties
dubbo.application.name=consumer-user
dubbo.registry.address=zookeeper://192.168.124.22:2181
(3)在provider-ticker中的com.gong.providerticjet下的service.TicketService
package com.gong.providerticket.service; public interface TicketService { public String getTicket(); }
service.TicketServiceImpl
package com.gong.providerticket.service; import com.alibaba.dubbo.config.annotation.Service; import org.springframework.stereotype.Component; @Component @Service public class TicketServieImpl implements TicketService { @Override public String getTicket() { return "囧妈"; } }
这里的@Service注解注意是dubbo包里面的。
在provider-ticket主入口加上EnableDubbo注解。
然后我们将com.gong.providerticket.service.TicketService拷贝一份到consumer-user下,注意包名要对应。
接着就可以进行测试了:
UserService.java
package com.gong.consumeruser.service; import com.alibaba.dubbo.config.annotation.Reference; import com.gong.providerticket.service.TicketService; import org.springframework.stereotype.Service; @Service public class UserService { @Reference TicketService ticketService; public void hello(){ String ticket = ticketService.getTicket(); System.out.println("买到票了:"+ticket); } }
这里的@Service是springboot中的。
最后是在ConsumerUserApplicationTests.java
package com.gong.consumeruser; import com.gong.consumeruser.service.UserService; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; @RunWith(SpringRunner.class) @SpringBootTest public class ConsumerUserApplicationTests { @Autowired UserService userService; @Test public void contextLoads() { userService.hello(); } }
3、进行测试
首先运行provider-ticket项目。然后再运行ConsumerUserApplicationTests.java中的contextLoads方法:
在consumer-user中成功调用了provider-ticket中的TicketServiceImpl.java中的方法。
