对本地变量名称的Java访问(Java Access to Local Variable Names)

对本地变量名称的Java访问(Java Access to Local Variable Names)

我正在编写一个程序，我希望在程序执行期间访问局部变量的变量名，并将它们从外部传递出去。 我知道Java在编译期间会转储局部变量名称，除非在调试模式下编译。

看过一些后，看来JDI / JPDA是这种工作的方式。 假设ref引用一个ThreadReference ，以下是我到目前为止：

ref.suspend(); StackFrame currentFrame = ref.frame(0); List<LocalVariable> vars = currentFrame.visibleVariables(); ref.resume();

两个问题：

我在正确的轨道上，还是有更好的方法来做到这一点？ 我如何获得设置为ref的ThreadReference ？ LocatableEvent似乎是我需要的，但任何人都可以提供如何使用它的例子吗？

提前谢谢了！

I'm currently writing a program in which I would like to access the variable names of local variables during execution of a program and pass them off externally. I'm aware that Java will dump local variable names during compilation unless compiled in debug mode.

After looking around some, it seems that JDI/JPDA is the way to go for this kind of work. Assuming ref refers to a ThreadReference, the following is what I have thus far:

ref.suspend(); StackFrame currentFrame = ref.frame(0); List<LocalVariable> vars = currentFrame.visibleVariables(); ref.resume();

Two questions:

Am I on the right track, or is there a better way to do this? How do I acquire the ThreadReference to set to ref? LocatableEvent seems to be what I need, but can anyone provide an example on how to use it?

Many thanks in advance!

Not a lot of people have experience with this stuff.

Look elsewhere for an answer. I had links to code but they are no longer. Cannot delete this answer because it was accepted answer.
