我是Apache ActiveMQ的新手。從生產者我發送以下內容:如何從ActiveMqMessage獲取消息文本
{"senderPhNumber":"9986085716","sendingTime":"2015-07-20T22:11:24","spCode":"000001","customerName":"Vinod"}
代碼從生產者
String text = messageStr;
TextMessage message = session.createTextMessage(text);
// Tell the producer to send the message
System.out.println("Sent message: " + text);
producer.send(message);
從消費,該消息是ActiveMqMessage
類型。消費者實現MessageListener
和內部onMessage()
我有以下代碼:
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,它被打印爲如下

如何檢索實際消息內容?
我試過了,但是當我嘗試(消息instanceof TextMessage)返回false。 –
您可以發佈您在消費方如何接收消息的代碼片段。它應該按照你所說的去做。 –
