推荐答案

另一个选项，在您的情况下可能相关或不相关，是在虚拟机内运行JVM（任何JVM）。大多数虚拟机都提供了存储和恢复状态的选项，因此应能够重新启动PC，在VM恢复时启动VM并让Java进程从原来的位置开始。

Another option, which may or may not be relevant in your case, is to run the JVM (any JVM) inside a virtual machine. Most virtual machines offer the option to store and resume state, so you should be able to restart your PC, fire up the VM when it comes back up and have the Java process pick up from where it was.

我在工作时使用VMWare Player进行IE测试，当我关闭并稍后重新打开它时，这就像上面说的那样工作。我通常不会在应用程序在VM中执行任何操作时执行此操作，但只要它们不访问任何外部资源（例如网络套接字），我希望它能够像VM永远不会关闭一样工作。

I use VMWare Player for testing on IE at work, and this works as noted above when I close and later reopen it. I don't generally do this when apps are doing anything of note in the VM, but as long as they aren't accessing any external resources (e.g. network sockets), I would expect it to work as if the VM was never shut down.
