SpringMVC集成Rocketmq

软件环境：
windows7
Rocketmq 4.2
（上）：安装配置RocketMq
一：配置环境变量
NAMESRV_ADDR=127.0.0.1:9876和rocketMQ的安装目录ROCKETMQ_HOME=
D:\rocketmq-4.2.0
二：启动nameserver
在bin目录下，使用mqnamesrv.cmd
启动成功输出：The Name Server boot success.
三：启动broker
使用命令mqbroker.cmd
启动broker时报错：
错误: 找不到或无法加载主类 Files\Java\jdk1.8.0_101\lib;C:\Program
解决办法：
runbroker.cmd里修改
set "JAVA_OPT=%JAVA_OPT% -cp %CLASSPATH%"这行为：set “JAVA_OPT=%JAVA_OPT% -cp “%CLASSPATH%””
（下）springMVC集成rocketMQ
引入依赖：

com.alibaba.rocketmq
rocketmq-client
3.2.6


com.alibaba.rocketmq
rocketmq-all

pom

生产者
MyProducer.java

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.alibaba.rocketmq.client.exception.MQClientException;
import com.alibaba.rocketmq.client.producer.DefaultMQProducer;

public class MyProducer {
	private final Logger logger = LoggerFactory.getLogger(MyProducer.class);
	private DefaultMQProducer defaultMQProducer;
	private String producerGroup;
	private String namesrvAddr;

	/**
	 * Spring bean init-method
	 */
	public void init() throws MQClientException {
		// 参数信息
		logger.info("DefaultMQProducer initialize!");
		logger.info(producerGroup);
		logger.info(namesrvAddr);
		// 初始化
		defaultMQProducer = new DefaultMQProducer(producerGroup);
		defaultMQProducer.setNamesrvAddr(namesrvAddr);
		defaultMQProducer.setInstanceName(String.valueOf(System
				.currentTimeMillis()));

		defaultMQProducer.start();
		System.out.println("DefaultMQProudcer start success!");
	}

	/**
	 * Spring bean destroy-method
	 */
	public void destroy() {
		defaultMQProducer.shutdown();
	}

	public DefaultMQProducer getDefaultMQProducer() {
		return defaultMQProducer;
	}

	// ---------------setter -----------------

	public void setProducerGroup(String producerGroup) {
		this.producerGroup = producerGroup;
	}

	public void setNamesrvAddr(String namesrvAddr) {
		this.namesrvAddr = namesrvAddr;
	}
}

消费者
MyConsumer .java

import java.util.List;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.alibaba.rocketmq.client.consumer.DefaultMQPushConsumer;
import com.alibaba.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext;
import com.alibaba.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus;
import com.alibaba.rocketmq.client.consumer.listener.MessageListenerConcurrently;
import com.alibaba.rocketmq.client.exception.MQClientException;
import com.alibaba.rocketmq.common.consumer.ConsumeFromWhere;
import com.alibaba.rocketmq.common.message.MessageExt;
import com.alibaba.rocketmq.common.protocol.heartbeat.MessageModel;
public class MyConsumer {
	 private final Logger logger = LoggerFactory.getLogger(MyConsumer.class);

	    private DefaultMQPushConsumer defaultMQPushConsumer;
	    private String namesrvAddr;
	    private String consumerGroup;

	    /**
	     * Spring bean init-method
	     */
	    public void init() throws InterruptedException, MQClientException {

	        // 参数信息
	        logger.debug("DefaultMQPushConsumer initialize!");
	        logger.debug(consumerGroup);
	        logger.debug(namesrvAddr);

	        // 一个应用创建一个Consumer，由应用来维护此对象，可以设置为全局对象或者单例

	        // 注意：ConsumerGroupName需要由应用来保证唯一
	        defaultMQPushConsumer = new DefaultMQPushConsumer(consumerGroup);
	        defaultMQPushConsumer.setNamesrvAddr(namesrvAddr);
	        defaultMQPushConsumer.setInstanceName(String.valueOf(System.currentTimeMillis()));

	        // 订阅指定MyTopic下tags等于MyTag

	        defaultMQPushConsumer.subscribe("MyTopic", "MyTag");

	        // 设置Consumer第一次启动是从队列头部开始消费还是队列尾部开始消费

	        // 如果非第一次启动，那么按照上次消费的位置继续消费
	        defaultMQPushConsumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

	        // 设置为集群消费(区别于广播消费)
	        defaultMQPushConsumer.setMessageModel(MessageModel.CLUSTERING);

	        defaultMQPushConsumer.registerMessageListener(new MessageListenerConcurrently() {

	            // 默认msgs里只有一条消息，可以通过设置consumeMessageBatchMaxSize参数来批量接收消息
	            @Override
	            public ConsumeConcurrentlyStatus consumeMessage(List msgs, ConsumeConcurrentlyContext context) {

	                MessageExt msg = msgs.get(0);
	                if (msg.getTopic().equals("MyTopic")) {
	                    // TODO 执行Topic的消费逻辑
	                	System.out.println("接收到了消息啊=========="+msg.toString());
	                    if (msg.getTags() != null && msg.getTags().equals("MyTag")) {
	                        // TODO 执行Tag的消费
	                    }
	                }
	                // 如果没有return success ，consumer会重新消费该消息，直到return success
	                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
	            }
	        });

	        // Consumer对象在使用之前必须要调用start初始化，初始化一次即可

	        defaultMQPushConsumer.start();

	        logger.debug("DefaultMQPushConsumer start success!");
	    }

	    /**
	     * Spring bean destroy-method
	     */
	    public void destroy() {
	        defaultMQPushConsumer.shutdown();
	    }

	    // ----------------- setter --------------------

	    public void setNamesrvAddr(String namesrvAddr) {
	        this.namesrvAddr = namesrvAddr;
	    }

	    public void setConsumerGroup(String consumerGroup) {
	        this.consumerGroup = consumerGroup;
	    }
}

生产者配置文件producer.xml

消费者配置文件：consumer.xml

然后将这两个xml导入到spring的配置文件里

到此就可以使用了。
