到目前为止列出的JAD链接似乎都是坏的，所以我找到了这个网站。工作得很好(至少对于Linux)!在Ubuntu 11.10上，不知什么原因，我不得不下载静态版本。

大多数Java反编译器都是基于JAD的。这是一个很棒的工具，但不幸的是，它已经有一段时间没有更新了，并且不能很好地处理Java 1.5+类。我还没有看到任何能够正确处理1.5+类的工具。

我尝试了几种，Procyon似乎最适合我。它正在积极开发中，支持最新版本Java的许多特性。

以下是我尝试过的其他方法:

CFR Promising, but often failed method decompilation. I'll be keeping my eye on this one. Also actively developed with support for the latest Java features. Krakatau Takes a different approach in that it tries to output equivalent Java code instead of trying to reconstruct the original source, which has the potential of making it better for obfuscated code. From my testing it was roughly on par with Procyon, but still nice to have something different. I did have to use the -skip command-line flag so it wouldn't stop on errors. Actively developed, and interestingly enough it's written in Python. JD-GUI Worked, but Procyon's output was much better. Here's a page comparing Procyon output to the original and JD-GUI. JD-GUI is also available as an Eclipse plugin, which didn't work for me at all. Doesn't seem to be open source and development seems sporadic. JAD Worked, but only supports Java 1.4 and below. Also available as an Eclipse plugin. No longer under development.

在IntelliJ IDEA平台上，可以使用Java反编译器IntelliJ Plugin。它允许您在调试过程中显示所有Java源代码，即使您没有全部Java源代码。它基于著名的工具JD-GUI。

这里有一些反编译器…快速搜索会得到:

Procyon:开源(Apache 2)，积极开发 Krakatau:开源(GPLv3)，并积极开发 CFR:开源(MIT)并积极开发 联合应用开发 DJ Java反编译器 摩卡

还有更多。

它们生成Java代码。Java自带一些功能，可以让您看到JVM字节代码(javap)。

JD-GUI真的很好。您只需打开一个JAR文件，然后浏览代码 你正在开发一个IDE。好东西。
