jms - Who manages a JMS session on the consumer side

Question

If I have a JMS queue and I wish to put a message on the queue from a publishing client, I need to first open a session, get the queue from its jndi name and then send the message to the queue.

But on the consumer side, how come I do not manually need to open a session and receive the message. Does the container always keep one open session per MDB (considering one MDB listening on one queue)

Answer 1

如果您使用的是 MDB，它们是容器管理的对象，则连接、会话、队列/主题和实际使用者都由容器管理。

您只需为 编写代码onMessage(Message m)，就是这样。
