java - 调试java混淆代码

Question

我们将混淆我们的项目，但不想失去远程调试和热交换的能力。

可能吗？哪些工具可以处理这个问题？我会对简单的混淆感到满意——只需重命名类/方法/变量。

[已编辑] 我们正在使用 Intellij IDEA，但找不到此任务的任何插件。

Answer 1

We have the same kind of needs (simple obfuscation, need to debug later) and we use ProGuard. It's a Java app, which can be integrated in an Ant task.

It can do a lot of things, but it's also fully tuneable. So you can keep your obfuscation simple. One of the options is to generate a "Symbol Correspondance Table", which allows you to retrive the non-obfucated code from the obfuscated one. (it keeps track that the variable xyz in the class qksdnqd is in fact myCuteVarName in the class MeaningfulClassName)

Edit: Obfuscation can be tricky. Some examples:

• You can't change the name of your main method.
• Do you use a classloader? Can it still retrieve the class after the obfuscation?
• What about your ORM Mapping? Your Spring Context? (if any)

Edit2: You can also see:

• Do you obfuscate your commercial Java code?

Answer 2

请参阅SD Java 混淆器。它去除注释和空格，并重命名所有不公开的成员/方法/类名称。

它还为您提供了代码如何混淆的映射，例如，对于每个符号 FOO 混淆为 XYZ，映射 FOO->XYZ。这意味着如果您得到提及 XYZ 的回溯，您可以轻松确定原始符号 FOO。当然，由于只有您（进行混淆处理的人）拥有此地图，因此只有您可以这样做。
