Question

我是Apache ActiveMQ的新手。来自制片人我发送以下内容：

{"senderPhNumber":"9986085716","sendingTime":"2015-07-20T22:11:24","spCode":"000001","customerName":"Vinod"}

制作人代码

String text = messageStr;
TextMessage message = session.createTextMessage(text);

// Tell the producer to send the message
System.out.println("Sent message: " + text );
producer.send(message);

来自消费者，消息的类型为ActiveMqMessage。消费者实施MessageListener和onMessage()内部我有以下代码：

public void onMessage(Message msg) {
    if (msg instanceof ActiveMQMessage){
        System.out.println("Inside If");
        try {
            ActiveMQMessage aMsg =  (ActiveMQMessage)msg;

            System.out.println( " Inside Listener ..." + aMsg);

            ProducerInfo prod = (ProducerInfo) aMsg.getDataStructure();
            consumer.close();
            session.close();
            connection.close();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

如果我打印消息，则打印如下

收到：ActiveMQMessage {commandId = 0，responseRequired = false， messageId = ID：AtulGupta-PC-50395-1437403689355-1：1：0：0：13， originalDestination = null，originalTransactionId = null，producerId = ID：AtulGupta-PC-50395-1437403689355-1：1：0：0，destination = 话题：//ActiveMQ.Advisory.MessageDelivered.Topic.atul，transactionId = null，expiration = 0，timestamp = 0，arrival = 0，brokerInTime = 1437403796470，brokerOutTime = 1437403796470，correlationId = null， replyTo = null，persistent = false，type = Advisory，priority = 0， groupID = null，groupSequence = 0，targetConsumerId = null，压缩 = false，userID = null，content = null，marshalledProperties = org.apache.activemq.util.ByteSequence@46347456,dataStructure = ActiveMQTextMessage {commandId = 5，responseRequired = false， messageId = ID：AtulGupta-PC-50417-1437403787762-3：1：1：1：1， originalDestination = null，originalTransactionId = null，producerId = ID：AtulGupta-PC-50417-1437403787762-3：1：1：1，destination = topic：// atul，transactionId = null，expiration = 0，timestamp = 1437403796468，到达= 0，brokerInTime = 1437403796470， brokerOutTime = 0，correlationId = null，replyTo = null，persistent = false，type = null，priority = 4，groupID = null，groupSequence = 0， targetConsumerId = null，compressed = false，userID = null，content = null，marshalledProperties = null，dataStructure = null， redeliveryCounter = 0，size = 0，properties = null，readOnlyProperties = false，readOnlyBody = false，droppable = false，jmsXGroupFirstForConsumer = false，text = null}，redeliveryCounter = 0，size = 0，properties = {originBrokerId = ID：AtulGupta-PC-50395-1437403689355-0：1， orignalDestination = ID：AtulGupta-PC-50417-1437403787762-3：1：1：1：1， originBrokerName =本地主机， orignalMessageId = ID：AtulGupta-PC-50417-1437403787762-3：1：1：1：1， originBrokerURL = tcp：// AtulGupta-PC：61616}，readOnlyProperties = true， readOnlyBody = true，droppable = false，jmsXGroupFirstForConsumer = 假}

如何检索实际的邮件内容？

Answer 1

我知道这已经过时了，但这就是我的所作所为（基本上）。重点是转换为ActiveMQTextMessage - 而不是ActiveMQMessage。

@Override
public void onMessage(Message message) {
    if (message instanceof ActiveMQTextMessage) {
        ActiveMQTextMessage textMessage = (ActiveMQTextMessage) message;
        try {
            handleMessage(textMessage);
        } catch (Exception e) {
            LOG.error("ActiveMQTextMessage handling failed", e);
        }
    } else {
        LOG.error("Message is not a text message " + message.toString());
    }
}

public static void handleMessage(ActiveMQTextMessage message) throws JMSException {
    try {
        String json = message.getText();
        DoSomethingWithJSON(json);
    } catch (Exception e) {
        System.out.println("Could not extract data to log from TextMessage");
        throw e;
    }

    mongoClient.close();
}

您是否尝试将消息转换为TextMessage，然后使用getText（）API获取消息。
