JAVA代码混淆方案

所属分类：[JAVA] | 创建时间：2014-11-11 | 文章属性：原创 | 文章来源：http://windfly.cn | 作者：windfly

##目的
>可快速、方便地对已经完成的jar或web项目进行代码混淆

##选用技术
>Allatori-5.1-Demo版，商用软件的演示版。在代码中会有System.out的打印      DEMO VERSION! NOT FOR COMMERCIAL USE!语句，在混淆的代码名中也会使用ALLATORI_DEMO关键字，但对项目运行没有明显影响。

##依赖两个jar包和一个配置文件
>allatori.jar  
>allatori-annotations.jar  
>config.xml

##运行方式 
>java -Xms128m -Xmx512m -jar allatori.jar config.xml

##配置文件常用内容

##针对桌面程序
```
<config>
    <jars>
        <jar in="test.jar" out="obf-test.jar"/>
        <jar in="mousegestures-1.2.jar" out="obf-mousegestures-1.2.jar"/>
    </jars>

<keep-names>
        <class template="class *.TestFrame"/>
    </keep-names>

<property name="log-file" value="log.xml"/>
</config>
```
##针对web程序，即war包，以某springMVC项目为例
```
<config>
    <jars>
        <jar in="${basedir}/war/vmp-product.war" out="${basedir}/war/obf-vmp-product.war"/>
    </jars>
    <classpath>
        <jar name="${basedir}/WebContent/WEB-INF/lib/*.jar"/>
        <jar name="${basedir}/devLib/*.jar"/>
    </classpath>
    <keep-names>
        
       
         
        
        <class template="public class *.interceptor.*">
            <method template="public get*(*)"/>
            <method template="public set*(*)"/>
        </class>
        <class template="public class *.listener.*">
            <method template="public get*(*)"/>
            <method template="public set*(*)"/>
        </class>
        <class template="public class *.filter.*">
            <method template="public get*(*)"/>
            <method template="public set*(*)"/>
        </class>
        <class template="class com.ausc.vmp.core.controller.MultView">
            <method template="public get*(*)"/>
            <method template="public set*(*)"/>
        </class>
        
        
        <class template="public class *Controller" ignore="true">
            
            <method access="public" parameters="keep"/>
        </class>
        
        
        <class template="public class com.ausc.vmp.core.beans.*">
            <field access="private+"/>
            <method template="public get*(*)"/>
            <method template="public set*(*)"/>
            <method template="public is*(*)"/>
            <method template="public has*(*)"/>
        </class>
        <class template="class com.ausc.vmp.plug.wh.bean.*">
            <field access="private+"/>
            <method template="public get*(*)"/>
            <method template="public set*(*)"/>
            <method template="public is*(*)"/>
            <method template="public has*(*)"/>
        </class>
        
        
        <class template="public class com.ausc.vmp.common.*">
            <field template="public static *"/>
            <method access="public"/>
        </class>
    </keep-names>

<expiry date="2014/12/12" string="EXPIRED!"/>
</config>
```

##与ant集成
```
<target name="obfuscate" depends="jar">
        <taskdef name="allatori" classname="com.allatori.ant.ObfuscatorTask" classpath="allatori.jar"/>
        <allatori config="config.xml"/>
</target>
```
