喵星之旅-狂奔的兔子-rabbitmq和spring整合

狂奔的兔子

一、创建maven项目

这里使用的是社区版idea和jdk8。

二、导入依赖

包含spring、rabbitmq等

        </dependency>
    </dependencies>

</project>

三、编写监听者（消费者）

创建类，实现接口MessageListener

这里创建了两个消费者类，其中message包含数据的全部内容，使用new String(message.getBody())可以获得传输的具体内容。

package club.kittybunny.consumer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

/**
 * @Author: bunny
 * @Description: 我是兔子我会喵，我叫喵星兔
 */
public class ConsumerOne implements MessageListener {
    private Logger logger = LoggerFactory.getLogger(ConsumerOne.class);
    public void onMessage(Message message) {
        logger.info("第一个消费者收到的信息 : " + message);
        logger.info("第一个消费者收到的信息 : " + new String(message.getBody()));
    }
}

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

/**
 * @Author: bunny
 * @Description: 我是兔子我会喵，我叫喵星兔
 */
public class ConsumerTwo implements MessageListener {
    private Logger logger = LoggerFactory.getLogger(ConsumerTwo.class);
    public void onMessage(Message message) {
        logger.info("第二个消费者收到的信息 : " + message);
        logger.info("第二个消费者收到的信息 : " + new String(message.getBody()));
    }
}

四、编写生产者类

这个类没有类型要求，@Service注册为bean，需要注入AmqpTemplate实现和交换机的连接，并使amqpTemplate.convertAndSend发送信息。

对于convertAndSend方法：

如果3个参数，第一个参数是交换机名字，第二个是路由key，第三个是发送的信息。

如果两个参数，就是省略了第一个参数，当没有默认交换机时会数据直接丢失。

package club.kittybunny.producer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;

/**
 * @Author: bunny
 * @Description: 我是兔子我会喵，我叫喵星兔
 */
@Service
public class Producer {
    private Logger logger = LoggerFactory.getLogger(Producer.class);

    @Autowired
    @Qualifier("amqpTemplate")
    private AmqpTemplate amqpTemplate;

    public void sendMessage(Object message) {
        logger.info("Send message:" + message);
        amqpTemplate.convertAndSend("MY_DIRECT_EXCHANGE", "FirstKey", "1" + message);
        amqpTemplate.convertAndSend("MY_DIRECT_EXCHANGE", "SecondKey", "2" + message);
        amqpTemplate.convertAndSend("SecondKey", "3" + message);//数据直接丢失
    }
}

五、编写配置文件

首先是log4j.properties 其中linux的路径改成相应系统对应格式

log4j.rootLogger=INFO,consoleAppender,fileAppender
log4j.category.ETTAppLogger=DEBUG, ettAppLogFile
log4j.appender.consoleAppender=org.apache.log4j.ConsoleAppender
log4j.appender.consoleAppender.Threshold=TRACE
log4j.appender.consoleAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.consoleAppender.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss SSS} ->[%t]--[%-5p]--[%c{1}]--%m%n
log4j.appender.fileAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.fileAppender.File=/home/bunny/logsforlog4j/debug1.log
log4j.appender.fileAppender.DatePattern='_'yyyy-MM-dd'.log'
log4j.appender.fileAppender.Threshold=TRACE
log4j.appender.fileAppender.Encoding=BIG5
log4j.appender.fileAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.fileAppender.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss SSS}-->[%t]--[%-5p]--[%c{1}]--%m%n
log4j.appender.ettAppLogFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ettAppLogFile.File=/home/bunny/logsforlog4j/ettdebug.log
log4j.appender.ettAppLogFile.DatePattern='_'yyyy-MM-dd'.log'
log4j.appender.ettAppLogFile.Threshold=DEBUG
log4j.appender.ettAppLogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.ettAppLogFile.layout.ConversionPattern=%-d{yyyy-MM-dd HH\:mm\:ss SSS}-->[%t]--[%-5p]--[%c{1}]--%m%n

然后是applicationContext.xml 将rabbit的配置单独放在一个文件中

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
    <!--将rabbit的配置单独放在一个文件中-->
    <import resource="classpath*:rabbitMQ.xml" />

    <!-- 扫描指定package下所有带有如 @Controller,@Service,@Resource 并把所注释的注册为Spring Beans -->
    <context:component-scan base-package="club.kittybunny.*" />

    <!-- 激活annotation功能 -->
    <context:annotation-config />

    <!-- 激活annotation功能 -->
    <context:spring-configured />
</beans>

最后是最主要的rabbitMQ.xml ，需要配置的内容略了交换机的绑定。这部分单独配置的。

    <!--通过指定下面的admin信息，当前producer中的exchange和queue会在rabbitmq服务器上自动生成
    RabbitAdmin主要用于在Java代码中对理队和队列进行管理，用于创建、绑定、删除队列与交换机，发送消息等。-->
    <rabbit:admin id="connectAdmin" connection-factory="connectionFactory" />

    <!--定义rabbit template用于数据的接收和发送 可使用exchange="MY_DIRECT_EXCHANGE" 指定默认交换机-->
 <rabbit:template id="amqpTemplate" connection-factory="connectionFactory"/>

 <!--消息接收者 --> 

<bean id="messageReceiver" class="club.kittybunny.consumer.ConsumerOne"></bean> 

<!--定义queue -->

<rabbit:listener-container connection-factory="connectionFactory">

</rabbit:listener-container> 

<!-- 消息接收者 -->

<!--定义queue --> 

<rabbit:queue name="MY_SECOND_QUEUE" durable="true" auto-delete="false" exclusive="false" declared-by="connectAdmin" /> 

<!-- queue litener 观察 监听模式 当有消息到达时会通知监听在对应的队列上的监听对象 --> 

<rabbit:listener-container connection-factory="connectionFactory"> 

<rabbit:listener queues="MY_SECOND_QUEUE" ref="receiverSecond" /> 

</rabbit:listener-container> 

</beans>

六、测试类

public class RabbitTest {

    private ApplicationContext context = null;

    @Test
    public void sendMessage() {
        context = new ClassPathXmlApplicationContext("applicationContext.xml");
        Producer messageProducer = (Producer) context.getBean("producer");
        int k = 100;
        while (k > 0) {
            messageProducer.sendMessage("第" + k + "次发送的消息");
            k--;
            try {
                Thread.sleep(1000);
                //Thread.sleep(Long.MAX_VALUE);
            } catch (Exception e) {
                e.printStackTrace();
            }
            //return;
        }
    }

}

至此结束。
