Proguard使用最新,最全教程,亲自试验

最近公司有一个项目,是外包项目,由于对方也有技术人员,出于技术上的保密,需要对class文件进行二次处理,于是网上找了好久,只发现Proguard是用的最广泛而且网上资料最多的。由于不是纯JAVA项目,而是WEB项目,涉及到大量的配置文件,所以用这个工具稍显吃力,于是开始研究这玩意,花了好长一段时间,重复试验了N次,终于整出来了,下面总结一下我的经验。。

首先我介绍下我要混淆的项目框架是jeecg+easyui+spring(包含xml配置文件,导致部分class文件不能直接混淆)。下面开始说详细的操作步奏:

1)将web项目的src目录的java文件打包,只需要选择java文件即可,其他配置文件什么的都不用选择,如图

2)http://proguard.sourceforge.net/下载proguard,目前我下载并使用的是proguard5.1(注:本人下载频道也有proguard5.1)。3)解压proguard5.1,执行 bin目录下的proguardgui.bat

然后会弹出如下图所示窗口

4)点击左边“input/output”菜单,然后点击右边的“Add input”按钮,添加需要混淆的jar包,我这里是test.jar,然后点击“add output”,选择输出的路径和包名。

5)下面开始添加支持库,这个地方很重要,很多同学刚开始使用这个工具的时候就是这里老是出问题。
   点击右边的“add”。

说明一下,这里最好把你的eclipse里java project里的libraries所有Library的jar包,包含web项目lib下面的包,jdk中jre下面的包和servlet.jar包等copy到一个目录,然后在这里加入这些jar包。系统默认会带上rt.jar,这里我们可以先remove掉,然后到jre下面copy所有的包。

6)点击“shrinking”,设置成如图所示。

10) 点击“process”,再点击“save configuration”,在弹出的对话框中,输入要保存的配置文件名称(这里我的是1111111.pro),最后点击“保存”.

11) 设置基本完成,关掉proguard窗口,找到刚刚保存的配置文件,开始手动修改部分配置。

以下是我的配置文件,经测试通过,手动修改的部分为红色字体

12)手动设置完成后保存,然后重新打开progrard,执行 bin目录下的proguardgui.bat。

   点击第一个选项“Proguard”,再点击“Load configuration”,选择我们刚才保存的“1111111.pro”进行加载。

13)然后点击Process,然后点击View configuration查看是否是已经修改过后的配置文件。

14) 确认是最新修改过的配置文件,然后点击process!开始混淆。。

如下图,表示混淆成功。。

15)我们可以用jd-gui反编译工具看看混淆后的效果。可以看到,之前设置不混淆的类都没有更换类名,而混淆的类都自动更换为a,b,c等类名了。到此,整个java项目混淆就成功了,然后把混淆成功的class文件拷贝到自己的web项目中,替换原先的class文件,然后用tomcat跑项目,发现和正常的class文件运行效果一样,项目正常运行。
