问题描述

给定一个 java.lang.reflect.Method 对象，是否有一种简单的方法来获取它覆盖的方法的层次结构.例如:

Given a java.lang.reflect.Method object, is there an easy way to obtain a hierachry of the methods it overrides. For example:

class A {
    public void someMethod() { ... }
}

interface B {
    public void someMethod();
}

class C extends A {
    public void someMethod() { ... }
}

class D extends C implements B {
    public void someMethod() { ... }
}

给定 D#someMethod 的 java.lang.reflect.Method 对象，我是否可以轻松获取树:

Given the java.lang.reflect.Method object for D#someMethod, can I easily get the tree:

D#someMethod
 |
 +- C#someMethod
 |   |
 |   +- A#someMethod
 |
 +- B#someMethod

我猜一定有一种简单的方法可以做到这一点，也许是现有的图书馆?

Am guessing there must be a simple way of doing this, perhaps an existing library?

推荐答案

最终没有找到有用的库，所以按照 assylias 的注释干脆用反射来遍历继承并构建树(包括超类和接口).我没有构建方法树，而是构建了随后可以遍历"的类树.

Ultimately did not find a useful library, so as per assylias comment simply used reflection to traverse the inheritance and build a tree (including superclasses and interfaces). I didn't build a method tree but rather a class tree which can subsequently be 'walked'.
