以编程方式检查.class文件是否扩展了特定类 [英] Checking programmatically if a .class file extends particular class

问题描述

我有一个问题，我一直在试图解决相当多个小时。在Eclipse插件中，我有一个ArrayList，它包含一些java .class文件的完整路径（作为字符串）。我想做的是检查列表中包含的类是否扩展一个特定的类。我想到解析文件，寻找扩展之后是什么，但是我们在谈论.class文件而不是.java文件。任何其他想法？

I have a problem I've been trying to solve for quite some hours. In an Eclipse plugin, I have an ArrayList that contains the full paths (as strings) of some java .class files. What I'd like to do is check if the classes that are included in the list extend a particular class. I thought about parsing the file, looking for what is after "extends," however we are talking about a .class file and not of a .java file. Any other ideas?

谢谢！

推荐答案

使用URLClassLoader加载文件（问题：你需要知道正确的父文件夹和Package + ClassName），并使用正常的java.lang.Class方法检查。

Use an URLClassLoader to load the file (Problem: You would need to know the right parent folder and Package + ClassName) and use the normal java.lang.Class methods to check.
