java - ActiveMq Producer 需要更长的时间才能将 JMS 消息发送到目标队列

Question

我们面临一个问题，从camel java DSL 路由向特定队列发送 JMS 消息，花费了近 20 秒，这对我们来说是非常糟糕的响应。这里仅以单线程运行，没有多线程。

能否请您指点一下，延迟的原因可能是什么？这是生产者挂起的场景吗，因为在 ActiveMq 代理配置中启用了生产者流控制。如果是，该如何处理？

Answer 1

听起来您错误地通过 JMS 进行请求/重新部署，并且 bt 默认使用 20 秒超时来等待回复消息。如果您只想以即发即忘的方式向队列发送消息，请确保将消息交换模式设置为 InOnly。
