RabbitMQ学习之基于spring-rabbitmq的RPC远程调用

http://blog.csdn.net/zhu_tianwei/article/details/40920985

spring-rabbitmq中实现远程接口调用，主要在com.rabbitmq.spring.remoting下几个类：
发布服务端(Server)：RabbitInvokerServiceExporter.java
接口调用客户端(Client)：RabbitInvokerProxyFactoryBean.java，RabbitInvokerClientInterceptor.java，
RabbitRpcClient.java（对RpcClient的简单封装，添加了发送消息时的选项：

mandatory--是否强制发送，immediate--是否立即发送，timeoutMs--超时时间）

实例如下创建自动删除非持久队列）：

1.测试服务接口TestService.Java

1. package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;
2. /**
3. * RPC服务接口
4. * @author ztw-pc
5. *
6. */
7. public interface TestService {
8. String say(String msg);
9. }

2.测试服务接口实现TestServiceImpl.java

1. package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;
2. public class TestServiceImpl implements TestService {
3. public String say(String msg) {
4. return "hello "+msg;
5. }
6. }

3..资源配置application.properties

1. #============== rabbitmq config ====================
2. rabbit.hosts=192.168.36.102
3. rabbit.username=admin
4. rabbit.password=admin
5. rabbit.virtualHost=/
6. rabbit.exchange=spring-queue-async
7. rabbit.queue=spring-queue-async
8. rabbit.routingKey=spring-queue-async

4.服务端配置applicationContext-rabbitmq-rpc-server.xml

1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:context="http://www.springframework.org/schema/context"
4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5. xsi:schemaLocation="
6. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
7. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
8. <context:property-placeholder location="classpath:application.properties"/>
9. <bean id="rabbitConnectionFactory" class="com.rabbitmq.spring.connection.RabbitConnectionFactory">
10. <property name="connectionFactory">
11. <bean class="com.rabbitmq.client.ConnectionFactory">
12. <property name="username" value="${rabbit.username}"/>
13. <property name="password" value="${rabbit.password}"/>
14. <property name="virtualHost" value="${rabbit.virtualHost}"/>
15. </bean>
16. </property>
17. <property name="hosts" value="${rabbit.hosts}"/>
18. </bean>
19. <bean id="rabbitChannelFactory" class="com.rabbitmq.spring.channel.RabbitChannelFactory">
20. <property name="connectionFactory" ref="rabbitConnectionFactory"/>
21. </bean>
22. <bean id="testServiceImpl" class="cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc.TestServiceImpl"/>
23. <bean id="testServiceExport" class="com.rabbitmq.spring.remoting.RabbitInvokerServiceExporter">
24. <property name="channelFactory" ref="rabbitChannelFactory"/>
25. <property name="serviceInterface" value="cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc.TestService"/>
26. <property name="service" ref="testServiceImpl"/>
27. <property name="exchange" value="${rabbit.exchange}"/>
28. <!-- 必须大写  -->
29. <property name="exchangeType" value="TOPIC"/>
30. <property name="routingKey" value="${rabbit.routingKey}"/>
31. <property name="queueName" value="${rabbit.queue}"/>
32. <property name="poolsize" value="5"/>
33. </bean>
34. </beans>

5.客服端配置applicationContext-rabbitmq-rpc-client.xml

1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:context="http://www.springframework.org/schema/context"
4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5. xsi:schemaLocation="
6. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
7. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
8. <context:property-placeholder location="classpath:application.properties"/>
9. <bean id="rabbitConnectionFactory" class="com.rabbitmq.spring.connection.RabbitConnectionFactory">
10. <property name="connectionFactory">
11. <bean class="com.rabbitmq.client.ConnectionFactory">
12. <property name="username" value="${rabbit.username}"/>
13. <property name="password" value="${rabbit.password}"/>
14. <property name="virtualHost" value="${rabbit.virtualHost}"/>
15. </bean>
16. </property>
17. <property name="hosts" value="${rabbit.hosts}"/>
18. </bean>
19. <bean id="rabbitChannelFactory" class="com.rabbitmq.spring.channel.RabbitChannelFactory">
20. <property name="connectionFactory" ref="rabbitConnectionFactory"/>
21. </bean>
22. <bean id="testService" class="com.rabbitmq.spring.remoting.RabbitInvokerProxyFactoryBean">
23. <property name="channelFactory" ref="rabbitChannelFactory"/>
24. <property name="serviceInterface" value="cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc.TestService"/>
25. <property name="exchange" value="${rabbit.exchange}"/>
26. <!-- 必须大写  -->
27. <property name="exchangeType" value="TOPIC"/>
28. <property name="routingKey" value="${rabbit.routingKey}"/>
29. <!--optional-->
30. <property name="mandatory" value="true"/>
31. <property name="immediate" value="false"/>
32. <property name="timeoutMs" value="3000"/>
33. <property name="poolSize" value="10"/>
34. </bean>
35. </beans>

6.启动服务端代码Server.java

1. package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;
2. import org.springframework.context.support.ClassPathXmlApplicationContext;
3. public class Server {
4. public static void main(String[] args) {
5. new ClassPathXmlApplicationContext("applicationContext-rabbitmq-rpc-server.xml");
6. }
7. }

7.客户端调用代码Client.java

1. package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;
2. import org.springframework.context.ApplicationContext;
3. import org.springframework.context.support.ClassPathXmlApplicationContext;
4. public class Client {
5. public static void main(String[] args) {
6. ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-rpc-client.xml");
7. TestService testService = (TestService) context.getBean("testService");
8. System.out.println(testService.say(" Tom"));
9. }
10. }

先启动服务端，再运行客户端调用。

运行结果：hello  Tom
