我正在尝试将 tanuki 服务包装器上的 Camel（基于 Spring）项目作为 Windows 服务运行。我尝试了集成方法 #1 和 #2：WrapperSimpleApp、WrapperStartStopApp 并且都导致了以下行为：

骆驼开始正常，包装器立即将其关闭！

起初我怀疑这与 Camel 非守护线程有关，但在使用了集成方法和 org.tanukisoftware.wrapper.WrapperStartStopApp.systemThreadCount 系统属性之后，我意识到 wrapper 关闭 JVM 肯定还有另一个原因。

有人会知道为什么吗？

这是包装器和骆驼日志 - 注意第 2 行和第 3 行：

好吧，由于骆驼的启动方式，问题确实是非守护线程湖。

Camel 是使用 oeg.apache.camel.spring.Main.start() 而不是 run() 启动的。

start() 只是在主线程上启动 Camel 以某种方式继续运行。这适用于在应用程序中运行时。另一方面，run() 会阻塞主线程，直到 Camel 或 JVM 退出。

调用 enableHangupSupport() 来注册一个关闭钩子以允许 Camel 在 JVM 退出时正常关闭也很有用。

我必须在应得的地方给予赞扬 :-) 感谢 tanuki java service wrapper 的超级专业团队为我解决了这个问题。
