springboot集成dubbo

摘要  springboot国外用的比较多，而dubbo国外又很少用，所有集成例子比较少。

spring  springboot  dubbo

1. dubbo XML文件引用：@ImportResource("classpath:dubbo-consum.xml")

2. 有的springboot版本会出现，dubbo注册服务的xml文件中引用的service报错不能注入，需要加入<dubbo:annotation package="com.dubbo.*" />

3. dubbo XSD文件需要手动导入到开发工具中

4. 最头疼的一个，就是版本冲突，首先是dubbo与spring的冲突，然后是zk与sf4j的冲突。

6. 上面的maven引入springboot用的版本是 1.3 . 0 的

7. <?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:jee= "http://www.springframework.org/schema/jee"
       xmlns:tx= "http://www.springframework.org/schema/tx"
       xmlns:dubbo= "http://code.alibabatech.com/schema/dubbo"
       xmlns:context= "http://www.springframework.org/schema/context"
       xsi:schemaLocation="http: //www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
       http: //www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
       http: //www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd
       http: //code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
       http: //www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"
       default -lazy-init= "false"  >
      <!-- 提供方应用名称信息，这个相当于起一个名字，我们dubbo管理页面比较清晰是哪个应用暴露出来的 -->
      <dubbo:application name= "dubbo-provider-dsp" ></dubbo:application>
      <dubbo:annotation  package = "pring.boot.*"  />
      <!-- 使用zookeeper注册中心暴露服务地址 -->
      <dubbo:registry address= "zookeeper://192.168.2.164:2181"  check= "false"  subscribe= "false"  register= "" ></dubbo:registry>
     <!-- 要暴露的服务接口 -->
     <dubbo:service  interface = "pring.boot.service.dubbo.DubboService"  ref= "dubboService"  />
   </beans>

8. 上面是生产者dubbo xml文件，文件放在resources中

9. @SpringBootApplication
   @ImportResource ( "classpath:dubbo-consum.xml" )
   public  class  Application {
   
       public  static  void  main(String[] args)  throws  Exception {
           SpringApplication.run(Application. class , args);
       }
   
   }

10. 这是引用dubbo文件，生产者和消费者都是一样引入。

<?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">
    <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
    <dubbo:application name= "dubbo-custom-dsp" />
    <dubbo:registry address= "zookeeper://192.168.2.164:2181"  />
    <!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
    <dubbo:reference id= "dubboService"  interface = "pring.boot.service.dubbo.DubboService"  />
</beans>
这是消费者dubbo xml文件 文件位置跟生产者一样
