从Java程序获取局部变量的名称和类型 [英] Getting name and type of local variables from a Java program

问题描述

这是我正在尝试的代码：

This is the code which I am trying out:

JavaCompiler compilerA = ToolProvider.getSystemJavaCompiler();
int resultA = compilerA.run(null,null,null,"/Users/a/Documents/Java/a.java");
System.out.println("Compile result code = " + resultA);
File fileA = new File("/Users/a/Documents/Java/a.class");

JavaCompiler compilerB = ToolProvider.getSystemJavaCompiler();
int resultB = compilerB.run(null,null,null,"/Users/a/Documents/Java/b.java");
System.out.println("Compile result code = " + resultB);
File fileB = new File("/Users/a/Documents/Java/b.class");

这里我正在编译Java类，然后使用反射来获取所有函数名称，参数并返回类型。但是，我不知道如何获取函数的局部变量的名称和返回类型。我尝试查找字节码大纲，但说它不适用于netbeans。请帮帮我。

Here I am compiling a Java class and then using reflection to get all the function names, parameters and return types. However, I have no clue how to get the names and return types of the local variables of the functions. I tried looking up bytecode outline but it says it isn't available for netbeans. Please help me out.

推荐答案

查看 javac编译器选项。尤其是-g：vars。

Look at the javac compiler options. Especially -g:vars.

这将为调试器填充局部变量表。

This fills the local variable table for debuggers.
