springboot下dubbo、zookeeper 结合使用

近期在研究dubbo框架

相信看到这篇博客的，dubbo的基础应该都有了

zookeeper的搭建走了点弯路，配置起来各种麻烦，妈的搞的好烦。

正好一直想用一下docker，但对docker只是有个简单的概念。

用了一晚上去研究docker，之后发现真的好用

搭建个zookeeper就跟玩似的。

这里记录一下遇到的一些坑！

1、springboot引入dubbo的配置文件

网上搜索了一下，大概的两种方式

1、这种方式是通过 ClassPathXmlApplicationContext 加载xml来获取上下文Context启动

 1 @SpringBootApplication
 2 3 public class WreserveApplication {
 4 
 5 public static void main(String[] args) throws IOException, InterruptedException {
 6 ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"dubbo-provider.xml"});
 7 context.start();
 8 System.in.read(); // press any key to exit
 9 }
10 
11 }

2、通过 @ImportResource({ "classpath:dubbo-provider.xml" }) 加载。

 1 @SpringBootApplication
 2 @ImportResource({ "classpath:dubbo-provider.xml" })
 3 public class WreserveApplication {
 4 @Bean
 5 public CountDownLatch closeLatch() {
 6 return new CountDownLatch(1);
 7 }
 8 
 9 public static void main(String[] args) throws IOException, InterruptedException {
10 ConfigurableApplicationContext context = SpringApplication.run(WreserveApplication.class, args);
11 CountDownLatch closeLatch = context.getBean(CountDownLatch.class);
12 closeLatch.await();
13 
14 }
15 
16 }

2、dubbo-provider.xml和dubbo-consumer.xml中需要注意的一些问题

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-2.5.xsd
 http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
 
 <dubbo:application name="demo-provider"/>
 <!-- use multicast registry center to export service -->
 <dubbo:registry address="zookeeper://192.168.99.100:2181"/>
 <!-- use dubbo protocol to export service on port 20880 -->
 <dubbo:protocol name="dubbo" port="20880"/>
 <!-- service implementation, as same as regular local bean -->
 <bean id="helloService" class="com.zhyonk.service.Impl.HelloServiceImpl"/>
 <!-- declare the service interface to be exported -->
 <dubbo:service interface="com.zhyonk.service.HelloService" ref="helloService"/>
 
</beans>

dubbo-consumer.xml

1、消费者要访问提供者，

<dubbo:reference id="helloService"
 interface="com.zhyonk.wreserve.service.HelloService" protocol="dubbo"
 <!-- service implementation, as same as regular local bean -->
 <bean id="helloService" class="com.zhyonk.service.Impl.HelloServiceImpl"/>
 <!-- declare the service interface to be exported -->
 <dubbo:service interface="com.zhyonk.service.HelloService" ref="helloService"/>

其中的interface必须要求同一个路径之下，不然对应不上，会出现下面的情况

正常情况下dubbo-admin中会显示

springboot下dubbo、zookeeper 结合使用

2、如果嫌自己搭建麻烦的话可以直接用用网站自动生成 http://start.dubbo.io/
