监听新思路

1.不必去破坏生产者消费者的关系,去创建死信队列的对应消费者,如果不同队列去创建对应的死信队列监听,没什么意义,复用刚开始的思路进行更改。mq配置更改指定监听死信队列,死信队列的名称是可以配置指定的

@Bean    public ActiveMQConnectionFactory connectionFactory() throws JMSException {        ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(brokerurl);        factory.setTrustAllPackages(true);//信任所有包下的序列化对象,解决无法发送对象消息        javax.jms.Connection connection = factory.createConnection();        connection.start();        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);        Queue queue = session.createQueue("ActiveMQ.DLQ");        MessageConsumer messageConsumer = session.createConsumer(queue);        messageConsumer.setMessageListener(new QueueListener());        factory.setUserName(userName);        factory.setPassword(password);        return factory;    }

新建监听类

/** * @author zhaokkstart * @create 2020-09-11 11:18 */public class QueueListener implements MessageListener {    @Override    public void onMessage(Message message) {        System.out.println("****消费者的消息:"+message);    }}

看下能从message获取到什么东西

public interface Message {
   static final int DEFAULT_DELIVERY_MODE = DeliveryMode.PERSISTENT;
   static final int DEFAULT_PRIORITY = 4;
   static final long DEFAULT_TIME_TO_LIVE = 0;
   String getJMSMessageID() throws JMSException;
   void setJMSMessageID(String id) throws JMSException;
   long getJMSTimestamp() throws JMSException;
   void setJMSTimestamp(long timestamp) throws JMSException;
   byte[] getJMSCorrelationIDAsBytes() throws JMSException;
   void setJMSCorrelationIDAsBytes(byte[] correlationID) throws JMSException;
   void setJMSCorrelationID(String correlationID) throws JMSException;
   String getJMSCorrelationID() throws JMSException;
   Destination getJMSReplyTo() throws JMSException;
   void setJMSReplyTo(Destination replyTo) throws JMSException;
   Destination getJMSDestination() throws JMSException;
   void setJMSDestination(Destination destination) throws JMSException;
   int getJMSDeliveryMode() throws JMSException;
   void setJMSDeliveryMode(int deliveryMode) throws JMSException;
   boolean getJMSRedelivered() throws JMSException;
   void setJMSRedelivered(boolean redelivered) throws JMSException;
   String getJMSType() throws JMSException;
   void setJMSType(String type) throws JMSException;
   long getJMSExpiration() throws JMSException;
   void setJMSExpiration(long expiration) throws JMSException;
   int getJMSPriority() throws JMSException;
   void setJMSPriority(int priority) throws JMSException;
   void clearProperties() throws JMSException;
   boolean propertyExists(String name) throws JMSException;
   boolean getBooleanProperty(String name) throws JMSException;
   byte getByteProperty(String name) throws JMSException;
   short getShortProperty(String name) throws JMSException;
   int getIntProperty(String name) throws JMSException;
   long getLongProperty(String name) throws JMSException;
   float getFloatProperty(String name) throws JMSException;
   double getDoubleProperty(String name) throws JMSException;
   String getStringProperty(String name) throws JMSException;
   Object getObjectProperty(String name) throws JMSException;
   Enumeration getPropertyNames() throws JMSException;
   void setBooleanProperty(String name, boolean value) throws JMSException;
   void setByteProperty(String name, byte value) throws JMSException;
   void setShortProperty(String name, short value) throws JMSException;
   void setIntProperty(String name, int value) throws JMSException;
   void setLongProperty(String name, long value) throws JMSException;
   void setFloatProperty(String name, float value) throws JMSException;
   void setDoubleProperty(String name, double value) throws JMSException;
   void setStringProperty(String name, String value) throws JMSException;
   void setObjectProperty(String name, Object value) throws JMSException;
   void acknowledge() throws JMSException;
   void clearBody() throws JMSException;}

还是对象里的那点东西,到有个新思路

  commandId = 5,    responseRequired = true,    messageId = ID: kk - 59648 - 1599635155556 - 1: 239: 1: 1: 1,     originalDestination = null, originalTransactionId = null,     producerId = ID: kk - 59648 - 1599635155556 - 1: 239: 1: 1,     destination = queue: //add_xxxxxx,     transactionId = null, expiration = 0, timestamp = 1599636301936, arrival = 0,     brokerInTime = 1599636301937, brokerOutTime = 1599636302110,     correlationId = null, replyTo = null, persistent = true, type = null,     priority = 4, groupID = null, groupSequence = 0,    targetConsumerId = null, compressed = false, userID = null,     content = org.apache.activemq.util.ByteSequence@54eae153,     marshalledProperties = org.apache.activemq.util.ByteSequence@1318dd4d,    dataStructure = null, redeliveryCounter = 0, size = 0, properties = {timestamp=1599636300958},    readOnlyProperties = true, readOnlyBody = true, droppable = false,    jmsXGroupFirstForConsumer = false}

不必去指定type维护队列的信息关系,获取

destination = queue: //add_xxxxxx,

即获取originalDestination属性,判断此消息的入队队列是哪个,然后获取该队列的消费者入队消息进行转换

这个方法是肯定能监听到死信队列的,亲测有效。

activemq死信队列怎么配置

(1) 死信队列的配置(一般采用默认)

1. sharedDeadLetterStrategy

不管是queue还是topic,失败的消息都放到这个队列中。下面修改activemq.xml的配置,可以达到修改队列的名字。

2. individualDeadLetterStrategy

可以为queue和topic单独指定两个死信队列。还可以为某个话题,单独指定一个死信队列。
