Dubbo消费者配置(spring文件方式配置)

消费者user-service-consumer

(1)导入Dubbo依赖与操作Zookeeper的客户端(curator)

<!-- 引入dubbo -->
<!-- https://mvnrepository.com/artifact/com.alibaba/dubbo -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.6.2</version>
</dependency>
<!-- 注册中心使用的是zookeeper，引入操作zookeeper的客户端端 -->
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-framework</artifactId>
<version>2.12.0</version>
</dependency>

　　

(2)配置配置服务消费者（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"
       xmlns:dubbo="http://dubbo.apache.org/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-4.3.xsd        http://dubbo.apache.org/schema/dubbo        http://dubbo.apache.org/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

       <context:component-scan base-package="com.atguigu.gmall.service.impl" />

       <dubbo:application name="order-service-consumer"  />
       <dubbo:registry address="zookeeper://127.0.0.1:2181" />
        
       <!--声明需要调用的远程服务的接口，生成远程服务代理-->
       <dubbo:reference interface="com.atguigu.gmall.service.UserService" id="userService" />

       <!--监控中心配置-->
      <dubbo:monitor protocol="registry" />
      <!--或者使用这个直连<dubbo:monitor address="127.0.0.1:7070"></dubbo:monitor>-->

</beans>

　　

main方法中：

public static void main( String[] args ) throws IOException {
    ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("consumer.xml");
    OrderService orderService = applicationContext.getBean(OrderService.class);
    orderService.initOrder("1");
    System.in.read();
}

这里注意一点消费者接收的服务id要与提供者所提供的id一致
