Is there a java classfile / bytecode editor to edit instructions?
提问by MRalwasser
Is there a utility (or eclipse plugin) for editing java class files? I'd like to manipulate the bytecode of a java class file without recompiling it nor having a complete buildpath.
是否有用于编辑 java 类文件的实用程序（或 eclipse 插件）？我想在不重新编译它也没有完整的构建路径的情况下操作 java 类文件的字节码。
E.g. to rename methods, add/delete instructions, change constants etc.
例如重命名方法、添加/删除指令、更改常量等。
The only utilities I found are:
我发现的唯一实用程序是：
classeditorbut it's very limited in functionality (e.g. renaming of things and manipulating instructions isn't possible).
jbedoesn't save changes (maybe because class verifying fails - before I made any changes, although the class runs perfectly)
(jbe initially had a classpath issue, adding the class path to the jbe.bat file helped)
classeditor但它的功能非常有限（例如，不可能重命名事物和操纵指令）。
jbe不保存更改（可能是因为类验证失败 - 在我进行任何更改之前，尽管类运行完美）
（jbe 最初有一个类路径问题，将类路径添加到 jbe.bat 文件有帮助）

I have not seen any byte code -> byte code frontends, but plenty backends.
我还没有看到任何字节码 -> 字节码前端，但有很多后端。
I would suggest that you have a look at the many byte code manipulation libraries like javassistwhich allow loading byte code, manipulate it, and save it back to disk, and then write a small main that does exactly that.
我建议您查看许多字节码操作库，例如javassist它们允许加载字节码，对其进行操作，然后将其保存回磁盘，然后编写一个执行此操作的小型 main。

I wrote an open source Java assembler and dissasembleryou may find useful.
我编写了一个开源 Java 汇编器和反汇编器，您可能会发现它很有用。
It lets you disassemble a classfile into human readable assembly, edit it, and then reassemble it into a class. It was originally designed for writing obfuscated crackmes, so there are a lot of obscure features it supports that many other tools don't. If you need any features it doesn't currently support, feel free to contact me and I'll see what I can do.
它允许您将类文件分解为人类可读的程序集，对其进行编辑，然后将其重新组装为一个类。它最初是为编写混淆的破解程序而设计的，因此它支持许多其他工具不支持的模糊功能。如果您需要它目前不支持的任何功能，请随时与我联系，我会看看我能做些什么。
