我知道Spring,但我是JMS中的新手,并开始阅读Spring JMS。从Spring JMS文档Spring doc,我阅读下列Spring中的JMS主题侦听器中的并发值
The number of concurrent sessions/consumers to start for each listener. Can either be a simple number indicating the maximum number (e.g. "5") or a range indicating the lower as well as the upper limit (e.g. "3-5").
Note that a specified minimum is just a hint and might be ignored at runtime. Default is 1; keep concurrency limited to 1 in case of a topic listener or if queue ordering is important; consider raising it for general queues.
只是想了解为什么要并发限于在主题听者的情况下?如果我增加它,说10而不是1,会发生什么?
