【问题描述】:
我正在使用 Websphere MQ 系统的发送/接收机制。
我以文本格式发送的 xml 应该会收到回复,但是我没有收到回复。
我知道 xml 正在“发送”正常,因为目标系统中的“事情正在发生” - 只是我没有收到回复。回复对我来说很重要,因为如果某些事情失败了,它可能会包含一条错误消息。
所以,我没有收到回复的原因 - 我不确定我的代码或 Websphere MQ 配置是否有问题。
非常感谢任何关于我的代码的指针或我应该要求 Websphere MQ 管理员查看的内容!
展示接收未发生的小型自包含示例如下所示:
public class CustomQueueConnection {
private MQQueueConnectionFactory connectionFactory;
private MQQueueConnection connection;
private void runTest() throws JMSException {
connect();
MQQueueSession session = (MQQueueSession) connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
MQQueue queue = (MQQueue) session.createQueue("queue:///REQ_SNAPSHOT.HT");
MQQueueSender sender = (MQQueueSender) session.createSender(queue);
TemporaryQueue temporaryQueue = session.createTemporaryQueue();
MQQueueReceiver receiver = (MQQueueReceiver) session.createReceiver(temporaryQueue);
TextMessage message = session.createTextMessage(
"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>\n" +
// my well constructed xml goes here...
);
message.setJMSReplyTo(temporaryQueue);
sender.send(message);
System.out.println("Sent: " + message);
JMSMessage receivedMessage = (JMSMessage) receiver.receive(10000);
System.out.println("Received: " + receivedMessage);
}
public boolean connect() {
boolean connected = false;
try {
connectionFactory = new MQQueueConnectionFactory();
connectionFactory.setCCSID(819);
connectionFactory.setPort(1417);
connectionFactory.setHostName("1.2.3.4");
connectionFactory.setQueueManager("GATE1");
connectionFactory.setChannel("CLIENTS.CHANNEL");
connectionFactory.setTemporaryModel("GATEWAY_MODEL_QUEUE");
connectionFactory.setTempQPrefix("MACHINE.USER_NAME.*");
connectionFactory.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP);
connection = (MQQueueConnection) connectionFactory.createQueueConnection();
connected = true;
} catch (JMSException e) {
connected = false;
}
return connected;
}
public static void main(String[] args) throws JMSException {
new CustomQueueConnection().runTest();
}
}
这是输出:
