在Java中生成一个在JVM关闭后幸存的进程 [英] Spawn a process in Java that survives a JVM shutdown

问题描述

我需要在Java（在Linux下专门）生成一个在JVM退出后继续运行的进程。我怎样才能做到这一点？

基本上Java应用程序应该生成一个更新程序，它会停止Java应用程序，更新文件然后再次启动它。

<我对hack&如果你有一个斜杠方法让它工作以及更好的设计方案：）

解决方案

如果你正在产卵使用 java.lang进行的过程。进程 它应该正常工作 - 我不相信当JVM退出时，生成的进程将会死亡。您可能会发现Ant库使您可以更轻松地控制产卵。

I need to spawn a process in Java (under Linux exclusively) that will continue to run after the JVM has exited. How can I do this?

Basically the Java app should spawn an updater which stops the Java app, updates files and then starts it again.

I'm interested in a hack & slash method to just get it working as well as a better design proposal if you have one :)

解决方案

If you're spawning the process using java.lang.Process it should "just work" - I don't believe the spawned process will die when the JVM exits. You might find that the Ant libraries make it easier for you to control the spawning though.
