应客户的需要，公司的整套业务项目要做一个私有化部署，所以涉及到要给客户提供源代码（并非真正的）。最后呢也就是给对方提供一个War包，因为版权和商业机密的问题，最后只能我们这边对代码做一下安全处理。

这里已经做出一些解释就暂且不再阐述关于Java反编译的深入研究

基于maven使用ProGuard进行混淆，大致分为三个步骤：

项目pom文件引入ProGuard依赖以及配置

<!-- ProGuard混淆插件-->
			<plugin>
                <groupId>com.github.wvengen</groupId>
                <artifactId>proguard-maven-plugin</artifactId>
                <version>2.0.11</version>
                <executions>
                    <execution>
                        <!-- 混淆时刻，这里是打包的时候混淆-->
                        <phase>package</phase>
                        <goals>
                            <!-- 使用插件的什么功能，当然是混淆-->
                            <goal>proguard</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <!-- 是否将生成的PG文件安装部署-->
                    <attach>true</attach>
                    <!-- 是否混淆-->
                    <obfuscate>true</obfuscate>
                    <!-- 指定生成文件分类 -->
                    <attachArtifactClassifier>pg</attachArtifactClassifier>
                    <proguardInclude>${basedir}/proguard.conf</proguardInclude>
                    <libs>
                        <lib>${java.home}/lib/rt.jar</lib>
                        <lib>${java.home}/lib/jce.jar</lib>
                    </libs>
                    <!-- 对什么东西进行加载，这里仅有classes成功，不可能对配置文件及JSP混淆吧-->
                    <injar>classes</injar>
                    <outjar>${project.build.finalName}-pg.jar</outjar>
                    <!-- 输出目录-->
                    <outputDirectory>${project.build.directory}</outputDirectory>
                </configuration>
            </plugin>

pom同级目录下添加proguard.conf文件

# 忽略所有警告，否则有警告的时候混淆会停止
-ignorewarnings

# JDK目标版本1.7
-target 1.7

# 不做收缩（删除注释、未被引用代码）
-dontshrink

# 不做优化（变更代码实现逻辑）
-dontoptimize

# 不路过非公用类文件及成员
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers

# 优化时允许访问并修改有修饰符的类和类的成员
-allowaccessmodification

# 确定统一的混淆类的成员名称来增加混淆
-useuniqueclassmembernames

# 不混淆所有包名，本人测试混淆后WEB项目问题实在太多，毕竟Spring配置中有大量固定写法的包名
-keeppackagenames

# 不混淆局部变量名
-keepparameternames

# 不混淆所有特殊的类 LocalVariable*Table,
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,Synthetic,EnclosingMethod

# 不混淆包下的所有类名
-keep class weg.base.** { <methods>; }
-keep class weg.service.** { <methods>; }
-keep class weg.dao.** { <methods>; }
-keep class weg.util.** { <methods>; }

# 不混淆quartz包下的所有类名，且类中的方法也不混淆
-keep class weg.quartz.** { <methods>; }

# 不混淆model包中的所有类以及类的属性及方法，实体包，混淆了会导致ORM框架及前端无法识别
-keep class weg.model.** {*;}

# 不混淆所有的set/get方法，毕竟项目中使用的部分第三方框架（例如Shiro）会用到大量的set/get映射
-keepclassmembers public class * {void set*(***);*** get*();}

# 保持类protected不被混淆
-keep public class * { public protected <fields>;public protected <methods>; }

2.maven package过程

maven打包过程是一个很崩溃的环节，尤其项目初期代码没有考虑优化项目臃肿的话，就是一个漫长的过程
