ProGuard
下载地址:http://proguard.sourceforge.net/index.html#downloads.html
因为公司项目都是 SSH 或者 SSJ 框架,涉及到非常多的配置文件,所以
a. 必须保留实现Action类中的公有的,友好的,私有的属性和公有的方法。
b. 因为配置文件中的类名是一个完整的类名,如果经过处理后就有可能找不到这个类。
c. 类中的属性是jsp页面所需要的,如果经过处理jsp页面就无法得到action中的数据。
所以混淆器的配置需要根据 工程使用的技术、标准的编码规范以及pro配置编写人员对工程的深入理解,否则极易导致工程无法正常运行。
ProGuard混淆时运行proguard.jar,并读取配置文件 ***.pro
ProGuardUI 图形化界面不能完全满足需要,需要单独配置 pro文件,但通过图形界面配置可以很方便的查看配置内容。如图:
java -jar ProGuard4.8\lib\proguard.jar @path\TrueCMS.pro
使用 proguard进行混淆时,若项目比较大,经常会报 OutOfMemory错误,则需要增加混淆器的内存
java -Xms256m -Xmx512m -jar proguardgui.jarconfiguration.pro参数
-include {filename} 从给定的文件中读取配置参数 -basedirectory {directoryname} 指定基础目录为以后相对的档案名称 -injars {class_path} 指定要处理的应用程序jar,war,ear和目录 -outjars {class_path} 指定处理完后要输出的jar,war,ear和目录的名称 -libraryjars {classpath} 指定要处理的应用程序jar,war,ear和目录所需要的程序库文件 -dontskipnonpubliclibraryclasses 指定不去忽略非公共的库类。 -dontskipnonpubliclibraryclassmembers 指定不去忽略包可见的库类的成员。保留选项 :
-keep {Modifier} {class_specification} 保护指定的类文件和类的成员 -keepclassmembers {modifier} {class_specification} 保护指定类的成员,如果此类受到保护他们会保护的更好 -keepclasseswithmembers {class_specification} 保护指定的类和类的成员,但条件是所有指定的类和类成员是要存在。 -keepnames {class_specification} 保护指定的类和类的成员的名称(如果他们不会压缩步骤中删除) -keepclassmembernames {class_specification} 保护指定的类的成员的名称(如果他们不会压缩步骤中删除) -keepclasseswithmembernames {class_specification} 保护指定的类和类的成员的名称,如果所有指定的类成员出席(在压缩步骤之后) -printseeds {filename} 列出类和类的成员-keep选项的清单,标准输出到给定的文件压缩:
-dontshrink 不压缩输入的类文件 -printusage {filename} -whyareyoukeeping {class_specification}优化:
-dontoptimize 不优化输入的类文件 -assumenosideeffects {class_specification} 优化时假设指定的方法,没有任何副作用 -allowaccessmodification 优化时允许访问并修改有修饰符的类和类的成员混淆 :
-dontobfuscate 不混淆输入的类文件 -printmapping {filename} -applymapping {filename} 重用映射增加混淆 -obfuscationdictionary {filename} 使用给定文件中的关键字作为要混淆方法的名称 -overloadaggressively 混淆时应用侵入式重载 -useuniqueclassmembernames 确定统一的混淆类的成员名称来增加混淆 -flattenpackagehierarchy {package_name} 重新包装所有重命名的包并放在给定的单一包中 -repackageclass {package_name} 重新包装所有重命名的类文件中放在给定的单一包中 -dontusemixedcaseclassnames 混淆时不会产生形形色色的类名 -keepattributes {attribute_name,...} 保护给定的可选属性,例如LineNumberTable, LocalVariableTable, SourceFile, Deprecated, Synthetic, Signature, and InnerClasses -renamesourcefileattribute {string} 设置源文件中给定的字符串常量
A. 综述
这是一个不应该在开源社区出现的东西,但它的的确确是一个开源的项目,正像它的名字一样,Proguard,即Program Guard(程序卫士),它代表了开源的相对面--代码保护。
经过几天的摸索,终于对Proguard应用于实际项目有一些不成熟的见解。
上面提过,对于Web工程,公司都是用了SSH/SSJ框架,这类框架中所有action/service/dao/domain以及包结构都固定写死在对应的配置文件中,这使得Proguard发挥的空间仅限于 service/dao内的方法、各部分的通用工具方法及util工具类,Proguard灵活配置的优势便显现出来了。
B. 使用说明
1.在Eclipse中选中需要混淆的工程,右键Exprot->选择jar文件导出备用
2. 打开 proguard4.8\lib 目录下的proguardgui.jar,在input/output 选项中增加输入文件,找到刚才导出的jar文件并确定,然后增加输出文件。
3.在 中增加工程lib文件夹下所有的jar包,以及java jre
4.Shrinking(压缩)中不设置任何配置 如图
5.Obfuscation如下图配置
其中 jss.txt 是我们提供给proguard 进行混淆的字符串,若为空,ProGuard会按小写英文字母a,b,c,d….顺序混淆。
6.Optimization如图配置
7.Information 如图配置
Target中选择当前jdk版本
8.在Process选项中选择 , 将配置保存成 **.pro文件9.打开pro文件
在配置后加入
-keep class WebRoot.WEB-INFO.lib.* ---不混淆lib文件夹中所有jar包 -keep class * extends cn.com.trueway.platform.** { public <methods>; } #不混淆继承于platform的所有类其他配置请根据实际情况进行添加
即开始混淆,混淆完的文件会根据配置文件输出到指定位置。
也可以使用命令行完成上述动作,且执行效率会有质的飞跃。
命令为:
(java -Xms256m -Xmx512m –jar D:\proguard4.8\lib\proguard.jar@D:\ rm.pro)
