我可以使用Java JMS通过Websphere MQ队列发送批处理消息吗？

Question

I'm working in a project that requires to send multiple messages to another application via asynchronous Websphere MQ messages. Actually I'm opening and closing sessions for every message I send. I appreciate your answers. By the way this is my first post here.

Answer 1

I figure something like this should work:

Session session = connection.createSession(false, SESSION.AUTO_ACKNOWLEDGE);
// Create first message
Message msgOne = session.createTextMessage("Message One");
// Set reply-to queue to REPLY1QUEUE
msgOne.setJMSReplyTo(session.createQueue("REPLY1QUEUE"));
// Create another message.
Message msgTwo = session.createTextMessage("Message Two");
msgTwo.setJMSReplyTo(session.createQueue("REPLY2QUEUE"));

// Initialize destination queue and message producer.
MessageProducer producer = session.createProducer(session.createQueue("DESTQUEUE"));

// Connect, send and close.
connection.start();
producer.send(msgOne);
producer.send(msgTwo);
connection.close();

// Close the session.
session.close();

If I'm not mistaken, the reply-to queue is optional.

In your question header, you mentioned the word batched which made me think you might want to send all the grouped messages in a single transaction so that all messages in the group are delivered or none at all. (An atomic send). If this is an important piece, I would slightly modify Friek's (clean and concise) code as follows:

Session session = connection.createSession(true, SESSION_TRANSACTED);
....
producer.send(msgOne);
producer.send(msgTwo);
session.commit();
....
