Maven WEB 项目使用ProGuard进行混淆，最佳解决方案&详解
本文中介绍的项目使用了SSM框架。
项目包结构：
该项目是典型的Maven WEB项目
主要混淆对象 对类的名称、属性、方法名都进行混淆
次要混淆对象 对类的名称不混淆，类的属性、方法名选择性混淆
非混淆对象 不进行混淆，混淆后可能出现异常
Maven 配置(pom.xml)
使用Maven集成的ProGuard插件，混淆配置不用单独建立文件

在项目location执行命令
mvn clean package -DskipTests -X
执行命令后，会在target下生成以下文件：
- classes-pg.jar 混淆后的classes文件，里面包含完整的项目结构
- proguard_map.txt 混淆内容的映射
- proguard_seed.txt 参与混淆的类
混淆完成后，将classes-pg.jar解压到应用服务器覆盖原有的classes文件，通常目录为
E:\tomcat7\webapps\项目名\WEB-INF\classes
运行服务，项目运行成功
查看目录下面文件（下面是包括包名的混淆）
通过反编译工具查看混淆代码
可以看出，混淆成功了！
下面是测试中遇到的部分问题及相关的解决方式：
解析：-target 1.7 jdk目标版本的问题
解析：-dontskipnonpubliclibraryclasses 不路过非公用类文件及成员
解析：-dontskipnonpubliclibraryclasses -dontskipnonpubliclibraryclassmembers 不路过非公用类文件及成员造成的bug
解析：-dontoptimize 变更代码逻辑引起的bug
还有一些其他的关于项目不能混淆的bug，这个需要根据项目而定。
