'Exiting' (ctrl+c) a process from console - Eclipse vs Intellij
提问by pdeva
It seems that in Eclipse, if you want to send ctrl+c to a process you cant. The terminate button on the console just kills the running process without running the shutdown hooks. I know that java itself doesnt allow sending a signal to another process.
似乎在 Eclipse 中，如果您想将 ctrl+c 发送到您不能的进程。控制台上的终止按钮只是终止正在运行的进程而不运行关闭挂钩。我知道 java 本身不允许向另一个进程发送信号。
However it seems that intellij idea does have a 'exit' button next to its 'stop' button which does allow shutdown hooks to run.
然而，intellij idea 的“停止”按钮旁边似乎确实有一个“退出”按钮，它允许关闭挂钩运行。
Can somebody tell me how intellij does this?
有人能告诉我intellij是如何做到的吗？
I need to send ctrl+c from my program to another java process too.
我也需要将 ctrl+c 从我的程序发送到另一个 java 进程。

Intellij use a native library to send a signal on Windows and the command kill on Unix.
Here is a source code
Intellij 使用本机库在 Windows 上发送信号，在 Unix 上使用 kill 命令。
这是一个源代码
Has you said you can't send a signal in Java. So you need to execute native code.
Look at the question here
你有没有说过你不能用Java发送信号。所以你需要执行本机代码。

It is my understanding that this happens only on Windows with Eclipse. Also see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=38016
据我了解，这仅在带有 Eclipse 的 Windows 上发生。另见：https: //bugs.eclipse.org/bugs/show_bug.cgi?id=38016
As far as just testing your hooks you can do it by calling System.exit() and then I suppose your users will not run the application using Eclipse so it's ok to count on it working for them.
至于只是测试你的钩子，你可以通过调用 System.exit() 来完成，然后我想你的用户不会使用 Eclipse 运行应用程序，所以可以指望它为他们工作。
