exchange的direct消费者

DirectMessageReceiver.java

package com.gm.consumer;

import java.io.UnsupportedEncodingException;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.Message;

import org.springframework.amqp.core.MessageListener;

public class DirectMessageReceiver implements MessageListener {

	private Logger logger = LoggerFactory.getLogger(DirectMessageReceiver.class);

	public void onMessage(Message message) {

		logger.info("consumer receive message------->:{}", message);

		String body;

		try {

			body = new String(message.getBody(), "UTF-8");

			System.out.println("consumer receive message------->"+body);

		} catch (UnsupportedEncodingException e) {

			e.printStackTrace();

		}

	}

}

exchange的topic消费者

TopicMessageReceiver.java

package com.gm.consumer;

import java.io.UnsupportedEncodingException;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.Message;

import org.springframework.amqp.core.MessageListener;

import org.springframework.stereotype.Component;

@Component

public class TopicMessageReceiver implements MessageListener {

	private Logger logger = LoggerFactory.getLogger(TopicMessageReceiver.class);

	public void onMessage(Message message) {

		logger.info("consumer receive message------->:{}", message);

		String body;

		try {

			body = new String(message.getBody(), "UTF-8");

			System.out.println("consumer receive message------->" + body);

		} catch (UnsupportedEncodingException e) {

			e.printStackTrace();

		}

	}

}

简单队列消费者

DefaultMessageReceiver.java

package com.gm.consumer;

import java.io.UnsupportedEncodingException;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.Message;

import org.springframework.amqp.core.MessageListener;

public class DefaultMessageReceiver implements MessageListener {

	private Logger logger = LoggerFactory.getLogger(DefaultMessageReceiver.class);

	public void onMessage(Message message) {

		logger.info("consumer receive message------->:{}", message);

		String body;

		try {

			body = new String(message.getBody(), "UTF-8");

			System.out.println("consumer receive message------->"+body);

		} catch (UnsupportedEncodingException e) {

			e.printStackTrace();

		}

	}

}

exchange的direct生产者

DirectMessageProducer.java

package com.gm.producer;

import java.io.IOException;

import javax.annotation.Resource;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.AmqpTemplate;

import org.springframework.amqp.rabbit.core.RabbitTemplate;

import org.springframework.stereotype.Service;

@Service

public class DirectMessageProducer {

	private Logger logger = LoggerFactory.getLogger(DirectMessageProducer.class);

	@Resource(name = "directAmqpTemplate")

	private AmqpTemplate directAmqpTemplate;

	public void sendMessage(Object message) throws IOException {

		logger.info("to send message:{}", message);

		directAmqpTemplate.convertAndSend("direct_queue_key", message);

	}

}

exchange的topic生产者

TopicMessageProducer.java

package com.gm.producer;

import java.io.IOException;

import javax.annotation.Resource;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.AmqpTemplate;

import org.springframework.amqp.rabbit.core.RabbitTemplate;

import org.springframework.stereotype.Service;

@Service

public class TopicMessageProducer {

	private Logger logger = LoggerFactory.getLogger(TopicMessageProducer.class);

	@Resource(name = "topicAmqpTemplate")

	private AmqpTemplate topicAmqpTemplate;

	public void sendMessage(Object message) throws IOException {

		logger.info("to send message:{}", message);

		topicAmqpTemplate.convertAndSend("log.info", message);

	}

}

简单队列生产者

DefaultMessageProducer.java

package com.gm.producer;

import java.io.IOException;

import javax.annotation.Resource;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.AmqpTemplate;

import org.springframework.amqp.rabbit.core.RabbitTemplate;

import org.springframework.stereotype.Service;

@Service

public class DefaultMessageProducer {

	private Logger logger = LoggerFactory.getLogger(DefaultMessageProducer.class);

	@Resource(name = "rabbitTemplate")

	RabbitTemplate rabbitTemplate;

	public void sendMessage(Object message) throws IOException {

		logger.info("to send message:{}", message);

		rabbitTemplate.convertAndSend("default_queue", message);

	}

}

单元测试

ProducerMain.java

package com.gm.producer;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class) // 使用junit4进行测试

@ContextConfiguration(locations = { "classpath:application.xml" }) // 加载配置文件

public class ProducerMain {

	private Logger logger = LoggerFactory.getLogger(ProducerMain.class);

	@Autowired

	DirectMessageProducer directMessageProducer;

	@Autowired

	TopicMessageProducer topicMessageProducer;

	@Autowired

	DefaultMessageProducer defaultMessageProducer;

	@Test

	public void send_messages() throws Exception {

		directMessageProducer.sendMessage("我是directMessageProducer发出的消息");

		topicMessageProducer.sendMessage("我是topicMessageProducer发出的消息");

		defaultMessageProducer.sendMessage("我是defaultMessageProducer发出的消息");

		while(true) {

		}

	}

}

结果
