重启自己 - 我可以从头开始重新初始化一切吗？ [英] Restart myself - can I reinitialize everything from scratch?

问题描述

我有这样的事情：

public static final String path;
static {
    path = loadProperties("config.conf").getProperty("path");
}

public static void main(String... args) {

    // ... do stuff (starting threads that reads the final path variable)

    // someone want's to update the path (in the config.conf file)
    restart(); // ???
}

我想重新初始化JVM再次调用静态初始值设定项，然后主（...）！

I want to reinitialize the JVM calling the static initializer again, and then main(...)!

能否完成？

推荐答案

您可以使用自定义类加载器启动应用程序，这将允许您加载和卸载静态变量。

You can start your application using a custom class loader, this will allow you to load and unload your static variables.

然而，基本上它是一个非常糟糕的设计需要去做这个。我喜欢让田野最终，但如果你想改变它们，你不应该让它们成为最终的。

However, basically its a very bad design to need to do this. I like making fields final, but you shouldn't make them final if you want to change them.
