rabbitmq学习11:基于rabbitmq和spring-amqp的远程接口调用

 此远程接口调用是基于RPC的

 

   先来看看提供暴露接口方法的配置

 

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
     <bean id="connectionFactory"
         class="org.springframework.amqp.rabbit.connection.SingleConnectionFactory">
         <constructor-arg value="localhost" />
         <property name="username" value="guest" />
         <property name="password" value="guest" />
     </bean>
     <bean id="amqpAdmin"
         class="org.springframework.amqp.rabbit.core.RabbitAdmin">
         <constructor-arg ref="connectionFactory" />
     </bean>
     <bean id="rabbitTemplate"
         class="org.springframework.amqp.rabbit.core.RabbitTemplate">
         <constructor-arg ref="connectionFactory"></constructor-arg>
     </bean>
     <bean id="testService" class="com.abin.test.TestServiceImpl"></bean>

     <bean
         class="org.springframework.amqp.rabbit.remoting.RabbitInvokerServiceExporter">
         <property name="connectionFactory" ref="connectionFactory" />
         <property name="serviceInterface"
             value="com.abin.test.TestService" />
         <property name="service" ref="testService" />
         <property name="exchange" value="service_exhange" />
         <property name="exchangeTypes" value="topic" />
         <property name="routingKey" value="routing.example.service" />
         <property name="queueName" value="incoming_queue_name" />
         <property name="poolsize" value="5" />
     </bean>
 </beans>

 

    RabbitInvokerServiceExporter类用于把接口services放到一个类型为“direct”的queue或者exchange中,并处理远程接口调用的回调。

 

    远程调用配置如下：

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
     <!-- 创建connectionFactory -->
     <bean id="connectionFactory"
         class="org.springframework.amqp.rabbit.connection.SingleConnectionFactory">
         <constructor-arg value="localhost" />
         <property name="username" value="guest" />
         <property name="password" value="guest" />
     </bean>
     <!-- 创建rabbitAdmin 代理类 -->
     <bean id="rabbitAdmin"
         class="org.springframework.amqp.rabbit.core.RabbitAdmin">
         <constructor-arg ref="connectionFactory" />
     </bean>
     <!-- 创建rabbitTemplate 消息模板类 -->
     <bean id="rabbitTemplate"
         class="org.springframework.amqp.rabbit.core.RabbitTemplate">
         <constructor-arg ref="connectionFactory"></constructor-arg>
     </bean>

     <bean id="testService"
         class="org.springframework.amqp.rabbit.remoting.RabbitInvokerProxyFactoryBean">
         <property name="connectionFactory" ref="connectionFactory" />
         <property name="serviceInterface"
             value="com.abin.test.TestService">
         </property>
         <property name="exchange" value="service_exhange" />
         <property name="exchangeTypes" value="topic" />
         <property name="routingKey" value="routing.example.service" />
     </bean>

     <bean id="testAction" class="com.abin.action.TestAction">
         <property name="testService" ref="testService" />
     </bean>
 </beans>

 

 RabbitInvokerProxyFactoryBean类通过拦截器方法调用在rabbitmq中已提供的远程接口信息。
