使用JNA或类似方法在Linux和Mac中关闭并重新启动计算机 [英] Using JNA or similar to shutdown and restart computer in linux and mac

问题描述

我正在尝试用Java编写一个函数，该函数将关闭，强制关闭，重新启动计算机并强制重新启动计算机，并且该软件应该可以在Windows，Linux和Mac上运行.

I am trying to write a function in java that will shutdown, force shutdown, restart and force restart the computer and it should work on Windows, Linux and Mac.

Windows没问题，但是由于sudo特权，我无法在Linux上运行命令以关闭计算机.因此，我当时正在考虑使用JNA关闭计算机(我知道您可以在Windows上使用JNA来执行此操作)，但是我找不到在线针对Linux或Mac的示例.

Windows is not a problem, but I am unable to run commands to shutdown on Linux due to the sudo privileges. I was therefore thinking of using JNA to shut down the computer (i know you can use JNA to do this on windows), but I can't find any examples online for linux or mac.

有人可以帮我吗?将不胜感激！

Can anyone help me out? It will be much appreciated!

即使不是通过JNA，只要我能找到实现此目标的方法，它也会对我有很大帮助.

Even if it's not through JNA, it would help me a lot as long as I can find some way to accomplish this.

推荐答案

如果仅使用Java就可以简单地覆盖系统保护，那将是一个很大的安全漏洞！我很惊讶您可以在Windows上执行此操作.

If you could simply override system protections just by using Java, that would be a big security flaw! I'm surprised you can do this on Windows.

无论如何，仅当您具有对计算机的管理访问权限以将程序设置在有权关闭/重新启动的特定组中时，才能完成此操作.否则，您将无法做到这一点.

Anyway, it can only be done if you have administrative access to your machine to set the program in a certain group which has the rights to shutdown/restart. Otherwise, you can't just do that.

我认为您可以直接将这些权限授予您的JVM，但是如果其他Java程序尝试执行关机操作，那将很危险.

I think you could give directly these rights to your JVM, but that could be dangerous if other java programs try to do shutdown.
