RabbitMQ学习之基于spring-rabbitmq的RPC远程调用

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

package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;

/**
* RPC服务接口
* @author ztw-pc
*
*/
public interface TestService {
String say(String msg);
}

2.测试服务接口实现TestServiceImpl.java

package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;

public class TestServiceImpl implements TestService {

public String say(String msg) {
return "hello "+msg;
}
}

3..资源配置application.properties

#============== rabbitmq config ====================
rabbit.hosts=192.168.36.102
rabbit.username=admin
rabbit.password=admin
rabbit.virtualHost=/
rabbit.exchange=spring-queue-async
rabbit.queue=spring-queue-async
rabbit.routingKey=spring-queue-async

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

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">

<context:property-placeholder location="classpath:application.properties"/>

<bean id="rabbitConnectionFactory" class="com.rabbitmq.spring.connection.RabbitConnectionFactory">
<property name="connectionFactory">
<bean class="com.rabbitmq.client.ConnectionFactory">
<property name="username" value="${rabbit.username}"/>
<property name="password" value="${rabbit.password}"/>
<property name="virtualHost" value="${rabbit.virtualHost}"/>
</bean>
</property>
<property name="hosts" value="${rabbit.hosts}"/>
</bean>
<bean id="rabbitChannelFactory" class="com.rabbitmq.spring.channel.RabbitChannelFactory">
<property name="connectionFactory" ref="rabbitConnectionFactory"/>
</bean>

<bean id="testServiceImpl" class="cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc.TestServiceImpl"/>

<bean id="testServiceExport" class="com.rabbitmq.spring.remoting.RabbitInvokerServiceExporter">
<property name="channelFactory" ref="rabbitChannelFactory"/>
<property name="serviceInterface" value="cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc.TestService"/>
<property name="service" ref="testServiceImpl"/>
<property name="exchange" value="${rabbit.exchange}"/>
<!-- 必须大写  -->
<property name="exchangeType" value="TOPIC"/>
<property name="routingKey" value="${rabbit.routingKey}"/>
<property name="queueName" value="${rabbit.queue}"/>
<property name="poolsize" value="5"/>
</bean>

</beans>

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

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">

<context:property-placeholder location="classpath:application.properties"/>

<bean id="rabbitConnectionFactory" class="com.rabbitmq.spring.connection.RabbitConnectionFactory">
<property name="connectionFactory">
<bean class="com.rabbitmq.client.ConnectionFactory">
<property name="username" value="${rabbit.username}"/>
<property name="password" value="${rabbit.password}"/>
<property name="virtualHost" value="${rabbit.virtualHost}"/>
</bean>
</property>
<property name="hosts" value="${rabbit.hosts}"/>
</bean>
<bean id="rabbitChannelFactory" class="com.rabbitmq.spring.channel.RabbitChannelFactory">
<property name="connectionFactory" ref="rabbitConnectionFactory"/>
</bean>

<bean id="testService" class="com.rabbitmq.spring.remoting.RabbitInvokerProxyFactoryBean">
<property name="channelFactory" ref="rabbitChannelFactory"/>
<property name="serviceInterface" value="cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc.TestService"/>
<property name="exchange" value="${rabbit.exchange}"/>
<!-- 必须大写  -->
<property name="exchangeType" value="TOPIC"/>
<property name="routingKey" value="${rabbit.routingKey}"/>
<!--optional-->
<property name="mandatory" value="true"/>
<property name="immediate" value="false"/>
<property name="timeoutMs" value="3000"/>
<property name="poolSize" value="10"/>
</bean>

</beans>

6.启动服务端代码Server.java

package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Server {

public static void main(String[] args) {
new ClassPathXmlApplicationContext("applicationContext-rabbitmq-rpc-server.xml");
}
}

7.客户端调用代码Client.java

package cn.slimsmart.rabbitmq.spring.rabbitmq.demo.rpc;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Client {

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-rpc-client.xml");
TestService testService = (TestService) context.getBean("testService");
System.out.println(testService.say(" Tom"));
}
}

先启动服务端，再运行客户端调用。

运行结果：hello Tom
