spring-web 集成 rabbitmq

 

引入java包：

本项目中仅引入了四个java包：amqp-client-5.7.3.jar，spring-rabbit-2.2.2.RELEASE.jar，spring-retry-1.2.4.RELEASE.jar，spring-amqp-2.2.2.RELEASE.jar

    <!-- 定义direct exchange，绑定queueTest -->
    <rabbit:direct-exchange name="exchangeTest" durable="true" auto-delete="false">

    </rabbit:listener-container>

</beans>

 spring中需要引入这个xml,  主要在总spring.xml。或者web.xml中需要引入下。

 

RabbitMqMessageConsumer

package club.codeapes.web.core.rabbitmq;

import club.codeapes.common.date.DateUtil;
import com.alibaba.fastjson.JSON;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

public class RabbitMqMessageConsumer implements MessageListener {

    @Override
    public void onMessage(Message message) {
        System.out.println("消费信息," + DateUtil.getNow("yyyy-MM-dd HH:mm:ss") + "---->" + message);
    }

}

 

RabbitMqMessageProducer：

package club.codeapes.web.core.rabbitmq;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;


@Repository
public class RabbitMqMessageProducer{

    @Autowired
    private AmqpTemplate amqpTemplate;

    public void sendMessage(Object message) {
        System.out.println("to send message:" + message);
        amqpTemplate.convertAndSend("queueTestKey", message);
    }

}
