springboot项目混淆方案
proguard简单来说是为了防止反编译，更准确的说，进行业务代码的混淆，是使得代码易读性变差。
引入proguard-maven-plugin
一：
<plugin>
<groupId>com.github.wvengen</groupId>
<artifactId>proguard-maven-plugin</artifactId>
<version>2.0.14</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>proguard</goal>
</goals>
</execution>
</executions>
<configuration>
<proguardVersion>6.0.3</proguardVersion>
<injar>${project.build.finalName}.jar</injar>
<outjar>${project.build.finalName}.jar</outjar>
<outjar>${project.build.finalName}.jar</outjar>
-->
<obfuscate>true</obfuscate>
<options>
<!--# JDK目标版本1.8-->
<option>-target 1.8</option>
<!-- 不做收缩（删除注释、未被引用代码）-->
<option>-dontshrink</option>
<!-- 不做优化（变更代码实现逻辑）-->
<option>-dontoptimize</option>
<!-- ##对于类成员的命名的混淆采取唯一策略-->
<option>-useuniqueclassmembernames</option>
<!--## 混淆类名之后，对使用Class.forName('className')之类的地方进行相应替代-->
<option>-adaptclassstrings</option>
<!--混淆时不生成大小写混合的类名，默认是可以大小写混合-->
<option>-dontusemixedcaseclassnames</option>
<!--忽略警告-->
<option>-ignorewarnings</option>
<!-- This option will replace all strings in reflections method invocations with new class names.
For example, invokes Class.forName('className')-->
<!-- <option>-adaptclassstrings</option> -->
<!-- This option will save all original annotations and etc. Otherwise all we be removed from files.-->
<!-- 不混淆所有特殊的类-->
<option>-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
</option>
<!-- This option will save all original names in interfaces (without obfuscate).-->
<!--
<option>-keepnames interface **</option>
-->
<!-- This option will save all original methods parameters in files defined in -keep sections,
otherwise all parameter names will be obfuscate.-->
<!--保留参数名字-->
<option>-keepparameternames</option>
<!--保留主进程入口-->
<!--
<option>-keep @org.springframework.boot.autoconfigure.SpringBootApplication class * {*;}</option>
-->
<!-- <option>-libraryjars **</option> -->
<!-- This option will save all original class files (without obfuscate) but obfuscate all in domain package.-->
<!--<option>-keep class !com.slm.proguard.example.spring.boot.domain.** { *; }</option>-->
<!--
<option>-keep class !com.bmsoft.graph.** { *; }</option>
-->
<option>-keep class com.bmsoft.graph.config.** { *; }</option>
<option>-keep class com.bmsoft.graph.LinkGraphApplication { *; }</option>
<option>-keep class com.bmsoft.graph.mapper.** { *; }</option>
<!--
<option>-keep class com.bmsoft.graph.auth.filter.** { *; }</option>
-->
<option>-keep class com.bmsoft.graph.aspect.** { *; }</option>
<option>-keep class com.bmsoft.graph.domain.** { *; }</option>
<option>-keep class com.bmsoft.graph.controller.** { *; }</option>
<!--
<option>-keep interface * extends * { *; }</option>
-->
<!--##保留枚举成员及方法-->
<option> -keepclassmembers enum * { *; }</option>
<option>-keepclassmembers class * {
<!-- @org.springframework.beans.factory.annotation.Autowired *; -->
@org.springframework.beans.factory.annotation.Autowired *;
@org.springframework.beans.factory.annotation.Value *;
}
</option>
</options>
<libs>
<!-- Include main JAVA library required.-->
<lib>${java.home}/lib/rt.jar</lib>
<lib>${java.home}/lib/jce.jar</lib>
<!-- <lib>${java.home}/lib/spring-boot-starter-web-1.4.1.RELEASE.jar</lib> -->
</libs>
</configuration>
<dependencies>
<dependency>
<groupId>net.sf.proguard</groupId>
<artifactId>proguard-base</artifactId>
<version>6.0.3</version>
</dependency>
</dependencies>
</plugin>
这里引用了com.github.wvengen的proguard-maven-plugin插件，使用的proguard-base版本是6.0.3
这里使用java8，因为libs那里照常配置rt.jar，jce.jar，如果是java9的话，则需要换成相应的模块。
另外指定proguard的阶段为package，springboot打包在repackage阶段
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<!-- <phase>none</phase> -->
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<mainClass>com.bmsoft.graph.LinkGraphApplication</mainClass>
</configuration>
</execution>
</executions>
</plugin>
bean命名重复异常
由于proguard混淆貌似不能指定混淆的类名在basePackages下面类名混淆后唯一，不同包名经常有a.class，b.class,c.class之类重复的类名，因此spring容器初始化bean的时候会报错。
异常信息如下:
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.example.demo.MvcDemoApplication]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'a' for bean class [com.example.demo.c.a] with existing, non-compatible bean definition of same name and class [com.example.demo.b.a]
at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:181) ~[spring-context-4.3.10.RELEASE.jar!/:4.3.10.RELEASE]
需要在更改bean 命名:
public class LinkGraphApplication {
public static class CustomGenerator implements BeanNameGenerator {
@Override
public String generateBeanName(BeanDefinition definition, BeanDefinitionRegistry registry) {
return definition.getBeanClassName();
}
}
public static void main(String[] args) {
new SpringApplicationBuilder(LinkGraphApplication.class)
.beanNameGenerator(new CustomGenerator())
.run(args);
}
}
运行jar包
nohup java -jar jar包名.jar -&
可能出现的问题
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'springfox.documentation.spring.web.scanners.ApiListingScanner' defined in URL
项目中引入了swagger 插件，需要在打包的时候，不进行bean的初始化配置@ConditionalOnProperty()
@Configuration
@ConditionalOnProperty(prefix = "swagger", value = {"enable"}, havingValue = "true")
@EnableSwagger2
public class SwaggerConfig {
}
注意
-keep class 类/包.** 表示保留类名
-keepclassmembers class 类/包.**{ *;} 表示保留类下边的所有变量，均不混淆

由于需要将源码打包做代码混淆，选择proguard，开始使用各种问题，各种jar包版本问题，但最终成功了，记录一下，也希望能够帮助大家
