如何使用Ant&YGuard混淆我的Web应用程序project.war?

使用ANT构建脚本的war文件.现在,我的公司希望我对.classes文件进行模糊处理

在发动战争之前将其分发给客户.当我用Google搜索时,我来了

跨 an example using YGuard库完成此任务.该链接非常有用,但是我只获得了部分成功,因为它混淆了所有java类,留下了未混淆的hibernate映射(* .hbm.xml)文件,这些文件引用了已经混淆的这些类.

例如:在混淆之后,对MenuGlobalBean.class的引用将转向类似A.B.H.I.N(其中A,B ……包名称和N是类名).

但是我的MenuGlobal.hbm.xml仍然将其称为

<class name="com.mycompany.myproduct.bean.MenuGlobalBean" table="MENU_GLOBAL">

而不是

<class name="A.B.H.I.N" table="MENU_GLOBAL">

现在我的问题是如何以这样的方式混淆我的war文件

模糊的类引用反映在我的* .hbm.xml&其他配置/属性文件(如果有).

下面是我使用YGuard库进行混淆的完整ANT构建脚本

使用我用来加密web.xml中引用的相同技巧 – 暂时将Hibernate .xml文件放入jar中. (请参阅“创建一个web.xml的jar(yguard所需)进行混淆”一节注释的部分.)
