springboot项目使用proguard配置代码混淆

springboot项目使用proguard配置代码混淆

代码混淆是一些软件开发过程中必不可少的步骤。常用的代码混淆技术有proguard maven plugin ,yguard maven plugin,procyon maven plugin,dex maven plugin .这些代码混淆技术大同小异，都是对maven打包生成class时进行干预，来完成对java字节码的代码混淆。本文以springboot项目使用proguard为例，讲一下如何使用proguard完成代码混淆。

物料准备:
1.pom引入proguard-maven-plugin插件
2.在proguard.cfg配置文件里设置具体的代码混淆配置
3.maven package 打包测试

pom.xml配置proguard插件

配置proguard.cfg文件

需要注意这个文件要配置到maven项目的根目录下

#jdk版本1.8#-target 1.8#不做收缩(不删除注释以及未被引用的代码)-dontshrink#不做优化(不变更代码实现逻辑)-dontoptimize#-dontobfuscate#-microedition#不使用大小写混合,混淆后的类名为小写-dontusemixedcaseclassnames#使用唯一的类名来混淆-useuniqueclassmembernames#允许访问并修改有修饰符的类和类的成员-allowaccessmodification#保持 包名不变-keeppackagenames#需要保持的属性：异常，内部类，注解等-keepattributes Exceptions,InnerClass,Signature,Deprecated,SourceFile,LineNumberTable,LocalVariable*Table,*Annotation*,Synthetic,EnclosingMethod#spring 相关的注解，不要混淆-keepclassmembers class * {  @org.springframework.** *;  @org.springframework.beans.factory.annotation.Autowired >;  @org.springframework.beans.factory.annotation.Autowired >;  @javax.annotation.PostConstruct *;  @javax.annotation.PreDestroy *;  @javax.annotation.Resource *;  @org.springframework.scheduling.annotation.Async >;}#不混淆所有的get/set方法-keepclassmembers public class *{  void set*(***); *** get*();}-keepnames interface ** {*;}-keep interface * extends * {*;}-keepparameternames-keepclassmembers enum * {*;}# 保持启动类不变-keep public class cn.thinkpet.springbootappscaffold.SpringbootAppScaffoldApplication {*;}#不混淆被Component等注解标记的类-keep @org.springframework.stereotype.Component class * {*;}-keep @org.springframework.stereotype.Service class * {*;}-keep @org.springframework.web.bind.annotation.RestController class * {*;}-keep @org.springframework.context.annotation.Configuration class * {*;}#-keep @org.aspectj.lang.annotation.Aspect class * {*;}-adaptclassstrings#跳过非公共库的类-skipnonpubliclibraryclasses#忽略警告-ignorewarnings-dontnote# 打印配置内容-printconfiguration# 配置不混淆某些类-keep class org.slf4j.** {*;}

打包测试

执行命令

mvn clean package -DskipTests

观察控制台，等待打包完成后，看下target目录如下

图中的
springboot-app-springbootappscaffold-0.0.1-SNAPSHOT.jar 即为代码混淆后的jar包

proguard_map.txt里记录了jar里哪些代码被混淆了，
如Apple.class 被混淆成 a.class 这种详细的内容 ，它是依据proguard.cfg里配置的项目来进行代码混淆的。
