推荐答案

你不能转换它。这不是Java的工作原理。



本质上，JAR是一组压缩的Java类文件。 Java类代码与Windows上使用的PE（可移植可执行代码）代码无关。 Java编译代码是字节码，它仅在JVM上运行，而EXE基于CPU指令集。 （在Microsoft Systems上，PE文件也可以针对CLR系统，它也基于类似于Java字节码，CIL代码的东西，但CIL也与JVM无关，它在CLR上运行，所以你可以忘记这个事实。 ）JVM有自己的API，在本机运行时系统中没有大量资源。



参见：

总的来说，你对转换JAR的整个想法完全没用。如果你解释你的最终目标，也许你会得到更多帮助。

You cannot "convert" it. This is not how Java works.

Essentially, JAR is a zipped set of Java class files. And Java class code has nothing to do with PE (Portable Executable) code used on Windows. Java compiled code is bytecode which operates only on JVM, while EXE is based on CPU instruction set. (On Microsoft Systems, PE files can also target CLR system, which is also based on something similar to Java bytecode, CIL code, but CIL also has nothing to do with JVM, it operates on CLR, so you can just forget this fact.) JVM has its own API with big set of resources unavailable in the native runtime system.

Overall, your whole idea of "converting" JAR is totally useless. Perhaps you can get more help if you explain your ultimate goals.
