You can do it by executing a shell command, if you java app has enough rights to do so. The command is...

如果您的 Java 应用程序有足够的权限，您可以通过执行 shell 命令来实现。命令是...

Runtime.getRuntime().exec("Rundll32.exe powrprof.dll,SetSuspendState Sleep");

That and other commands are shown here.

此处显示了该命令和其他命令。

Anyone suggesting rundll32 should be shot, very few functions are designed to be called by rundll32 and SetSuspendState is notone of them. You will get random behavior (Hibernate vs Standby and Forced vs not forced etc) See this blog entry for more details.

任何建议rundll32的人都应该被枪杀，很少有函数被设计为由rundll32调用，SetSuspendState不是其中之一。您将获得随机行为（休眠与待机和强制与非强制等）有关更多详细信息，请参阅此博客条目。

I currently solved this using https://github.com/twall/jna. Information about the call from http://www.pinvoke.net/default.aspx/powrprof.SetSuspendState

我目前使用https://github.com/twall/jna解决了这个问题。有关来自http://www.pinvoke.net/default.aspx/powrprof.SetSuspendState的调用的信息

import com.sun.jna.Native;
import com.sun.jna.Platform;
public class WindowsSuspend {
  public static native boolean SetSuspendState(boolean hibernate, boolean forceCritical, boolean disableWakeEvent);

  static {
    if (Platform.isWindows())
      Native.register("powrprof");
  }
}

Call it than with WindowsSuspend.SetSuspendState(false, false, false).

调用它比WindowsSuspend.SetSuspendState(false, false, false)。

No. You'd need to execute a separate binary via Runtime.exec().

不，您需要通过Runtime.exec().

You may want to look at the OnNow/ACPI Support here.

您可能想在此处查看 OnNow/ACPI 支持。

There is also an old SO post that talks about it here.Probably the reverse of what you want. Might give you some clues though.

还有一个旧的 SO 帖子在这里讨论了它。可能与您想要的相反。不过可能会给你一些线索。
