我知道 Spring,但我是 JMS 的新手,并开始阅读 Spring JMS。从 Spring JMS doc Spring doc中,我阅读了以下内容
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.
只是想了解为什么在主题侦听器的情况下并发限制为1 ?如果我增加它,说 10 而不是 1,会发生什么?
