可以获取在Java中调用方法的类的文件路径吗？ [英] Possible to get the file-path of the class that called a method in Java?

问题描述

比方说我有这个场景

C：\ Users \ Name \ Document \ Workspace \ Project \ Src\Com\Name\Foo.java

C:\Users\Name\Documents\Workspace\Project\Src\Com\Name\Foo.java

Public class Foo {

    public Foo() {
        Bar b = new Bar();
        b.method();
    }
}

然后我们可以说课程栏位于.JAR中正在用作库的文件，是否可以确定调用method（）的类来自何处？ （在这种情况下，Foo类）

Then lets say that class Bar is in a .JAR file that's being used as a library, is it possible to figure out where the class that called method() was from? (in this case, the Foo class)

我做了一点环顾谷歌并找不到任何东西，这段代码肯定会简化我的库位。

I've done a little looking around Google and can't find anything, and this code would definately simplify my library quite a bit.

推荐答案

如果你需要从方法Bar＃方法中获取调用者类文件的路径，那么你可以使用这样的东西：

If you need to get path of the caller class file from inside the method Bar#method then you can use something like this:

StackTraceElement[] stackTrace = new Throwable().getStackTrace();
String callerFilePath = getClass().getClassLoader().getResource(stackTrace[1].getClassName().replace('.', '/') + ".class"));
