1.  添加ActiveMQ配置信息

import javax.jms.Queue;
     
    import org.apache.activemq.ActiveMQConnectionFactory;
    import org.apache.activemq.RedeliveryPolicy;
    import org.apache.activemq.command.ActiveMQQueue;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.jms.annotation.EnableJms;
    import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
    import org.springframework.jms.core.JmsTemplate;
     
    @EnableJms  
    @Configuration  
    public class ActiveMQ4Config {  
     
    	@Bean
    	public Queue queue(){
    		return new ActiveMQQueue("queue1");
    	}
     
    	@Bean
    	public RedeliveryPolicy redeliveryPolicy(){
    	        RedeliveryPolicy  redeliveryPolicy=   new RedeliveryPolicy();
    	        //是否在每次尝试重新发送失败后,增长这个等待时间
    	        redeliveryPolicy.setUseExponentialBackOff(true);
    	        //重发次数,默认为6次   这里设置为10次
    	        redeliveryPolicy.setMaximumRedeliveries(10);
    	        //重发时间间隔,默认为1秒
    	        redeliveryPolicy.setInitialRedeliveryDelay(1);
    	        //第一次失败后重新发送之前等待500毫秒,第二次失败再等待500 * 2毫秒,这里的2就是value
    	        redeliveryPolicy.setBackOffMultiplier(2);
    	        //是否避免消息碰撞
    	        redeliveryPolicy.setUseCollisionAvoidance(false);
    	        //设置重发最大拖延时间-1 表示没有拖延只有UseExponentialBackOff(true)为true时生效
    	        redeliveryPolicy.setMaximumRedeliveryDelay(-1);
    	        return redeliveryPolicy;
    	}
        @Bean
        public ActiveMQConnectionFactory activeMQConnectionFactory (@Value("${activemq.url}")String url,RedeliveryPolicy redeliveryPolicy){  
            ActiveMQConnectionFactory activeMQConnectionFactory =  
                    new ActiveMQConnectionFactory(
                           "admin",
                            "admin",
                            url);
            activeMQConnectionFactory.setRedeliveryPolicy(redeliveryPolicy);
            return activeMQConnectionFactory;
        }
        
        @Bean
        public JmsTemplate jmsTemplate(ActiveMQConnectionFactory activeMQConnectionFactory,Queue queue){
        	JmsTemplate jmsTemplate=new JmsTemplate();
        	jmsTemplate.setDeliveryMode(2);//进行持久化配置 1表示非持久化，2表示持久化
        	jmsTemplate.setConnectionFactory(activeMQConnectionFactory);
        	jmsTemplate.setDefaultDestination(queue); //此处可不设置默认，在发送消息时也可设置队列
        	jmsTemplate.setSessionAcknowledgeMode(4);//客户端签收模式
        	return jmsTemplate;
        }
        
        //定义一个消息监听器连接工厂，这里定义的是点对点模式的监听器连接工厂
        @Bean(name = "jmsQueueListener")
        public DefaultJmsListenerContainerFactory jmsQueueListenerContainerFactory(ActiveMQConnectionFactory activeMQConnectionFactory) {
            DefaultJmsListenerContainerFactory factory =
                    new DefaultJmsListenerContainerFactory();
            factory.setConnectionFactory(activeMQConnectionFactory);
            //设置连接数
            factory.setConcurrency("1-10");
            //重连间隔时间
            factory.setRecoveryInterval(1000L);
            factory.setSessionAcknowledgeMode(4);
            return factory;
        }
     
    }

1.  消费者如下：使用异步监听（使用监听器形式）

import javax.jms.JMSException;
    import javax.jms.Session;
    import javax.jms.TextMessage;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.stereotype.Component;
     
    @Component
    public class Consumer {
     
    	private final static Logger logger = LoggerFactory
    			.getLogger(Consumer.class);
    	
    	@JmsListener(destination = "queue1", containerFactory = "jmsQueueListener")
    	public void receiveQueue(final TextMessage text, Session session)
    			throws JMSException {
    		try {
    			logger.debug("Consumer收到的报文为:" + text.getText());
    			text.acknowledge();// 使用手动签收模式，需要手动的调用，如果不在catch中调用session.recover()消息只会在重启服务后重发
    		} catch (Exception e) {	
    			session.recover();// 此不可省略 重发信息使用
    		}
    	}
    }

1.  生产者如下

import javax.jms.Destination;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.jms.core.JmsTemplate;
    import org.springframework.stereotype.Component;
     
    @Component
    public class Producer {
    	
    	@Autowired
    	private JmsTemplate jmsTemplate;
    	/**
    	 * 发送消息，estination是发送到的队列，message是待发送的消息
    	 * @param destination
    	 * @param message
    	 */
    	public void sendMessage(Destination destination, final String message) {
    		System.out.println(jmsTemplate.getDeliveryMode());
    		jmsTemplate.convertAndSend(destination, message);
    	}
    	/**
    	 * 发送消息，message是待发送的消息
    	 * @param message
    	 */
    	public void sendMessage(final String message) {
    		System.out.println(jmsTemplate.getDeliveryMode());
    			jmsTemplate.convertAndSend("queue1",message);
    	}
     
    }
