ActiveMq Producer 将 JMS 消息发送到目标队列需要更长的时间

Question

我们面临一个问题，从骆驼 java DSL 路由向特定队列发送 JMS 消息，需要将近 20 秒，这对我们来说是非常糟糕的响应。这里只运行单线程，没有多线程。

请您指点一下，延迟的原因可能是什么。由于在 ActiveMq 代理配置中启用了生产者流控制，是生产者挂起的场景吗？如果是，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 fire and forget 样式向队列发送消息，请确保将消息交换模式设置为 InOnly。
