在 Java 中生成一个在 JVM 关闭后仍然存在的进程 [英] Spawn a process in Java that survives a JVM shutdown

问题描述

我需要在 Java 中生成一个进程(仅在 Linux 下)，该进程将在 JVM 退出后继续运行.我怎样才能做到这一点?

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?

基本上，Java 应用程序应该生成一个更新程序，用于停止 Java 应用程序、更新文件然后再次启动它.

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

我对 hack & 感兴趣斜线方法来让它工作，如果你有一个更好的设计方案:)

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

推荐答案

如果您使用 java.lang.Process 它应该正常工作" - 我不相信生成的进程会在 JVM 退出时死亡.您可能会发现 Ant 库使您可以更轻松地控制生成.

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.
