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

RabbitMQ学习笔记;spring-amqp;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代码  

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <beans xmlns="http://www.springframework.org/schema/beans"  
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
4.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
5.     <bean id="connectionFactory"  
6.         class="org.springframework.amqp.rabbit.connection.SingleConnectionFactory">  
7.         <constructor-arg value="localhost" />  
8.         <property name="username" value="guest" />  
9.         <property name="password" value="guest" />  
10.     </bean>  
11.     <bean id="amqpAdmin"  
12.         class="org.springframework.amqp.rabbit.core.RabbitAdmin">  
13.         <constructor-arg ref="connectionFactory" />  
14.     </bean>  
15.     <bean id="rabbitTemplate"  
16.         class="org.springframework.amqp.rabbit.core.RabbitTemplate">  
17.         <constructor-arg ref="connectionFactory"></constructor-arg>  
18.     </bean>  
19.     <bean id="testService" class="com.abin.test.TestServiceImpl"></bean>  
20.   
21.     <bean  
22.         class="org.springframework.amqp.rabbit.remoting.RabbitInvokerServiceExporter">  
23.         <property name="connectionFactory" ref="connectionFactory" />  
24.         <property name="serviceInterface"  
25.             value="com.abin.test.TestService" />  
26.         <property name="service" ref="testService" />  
27.         <property name="exchange" value="service_exhange" />  
28.         <property name="exchangeTypes" value="topic" />  
29.         <property name="routingKey" value="routing.example.service" />  
30.         <property name="queueName" value="incoming_queue_name" />  
31.         <property name="poolsize" value="5" />  
32.     </bean>  
33. </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代码  

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <beans xmlns="http://www.springframework.org/schema/beans"  
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
4.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
5.     <!-- 创建connectionFactory -->  
6.     <bean id="connectionFactory"  
7.         class="org.springframework.amqp.rabbit.connection.SingleConnectionFactory">  
8.         <constructor-arg value="localhost" />  
9.         <property name="username" value="guest" />  
10.         <property name="password" value="guest" />  
11.     </bean>  
12.     <!-- 创建rabbitAdmin 代理类 -->  
13.     <bean id="rabbitAdmin"  
14.         class="org.springframework.amqp.rabbit.core.RabbitAdmin">  
15.         <constructor-arg ref="connectionFactory" />  
16.     </bean>  
17.     <!-- 创建rabbitTemplate 消息模板类 -->  
18.     <bean id="rabbitTemplate"  
19.         class="org.springframework.amqp.rabbit.core.RabbitTemplate">  
20.         <constructor-arg ref="connectionFactory"></constructor-arg>  
21.     </bean>  
22.   
23.     <bean id="testService"  
24.         class="org.springframework.amqp.rabbit.remoting.RabbitInvokerProxyFactoryBean">  
25.         <property name="connectionFactory" ref="connectionFactory" />  
26.         <property name="serviceInterface"  
27.             value="com.abin.test.TestService">  
28.         </property>  
29.         <property name="exchange" value="service_exhange" />  
30.         <property name="exchangeTypes" value="topic" />  
31.         <property name="routingKey" value="routing.example.service" />  
32.     </bean>  
33.   
34.     <bean id="testAction" class="com.abin.action.TestAction">  
35.         <property name="testService" ref="testService" />  
36.     </bean>  
37. </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。
