SpringBoot + proguard+maven多模块实现代码混淆的方法

作者:小酒仙028

这篇文章主要介绍了SpringBoot + proguard+maven多模块实现代码混淆的方法,多模块跟单模块一样,在需要混淆模块的pom文件中加入proguard依赖及配置,本文给大家讲解的非常详细,感兴趣的朋友一起看看吧

上文介绍了单个springboot的maven工程实现代码混淆,本文将会介绍多maven工程实现代码混淆。

多模块跟单模块一样,在需要混淆模块的pom文件中加入proguard依赖及配置。

 演练版本

springboot:2.5.8

jdk:1.8

proguard: 7.1.0

 新建springboot多Maven工程

新建springboot多maven工程,结构如下图,proguard-root 是顶级父工程,proguard-modu01、proguard-mudu02是两个业务模块,proguard-server是springboot启动服务类模块。

接下来会对proguard-modu01、proguard-mudu02两个模块实现proguard代码混淆。

下面以proguard-modu01工程为例介绍。

proguard-modu01 工程结构

proguard-modu01 的pom.xml配置代码混淆

 本次我将proguard配置项放入 <options> </options>内,也可以单独配置在proguard.cfg文件内。

特别注意避坑:多maven工程代码混淆一定要配置:<option>-keepdirectories</option>,否则在以后访问代码混淆子模块的controller时会提示404错误。

<!-- 配置代码混淆 结束-->
</project>

此时,已完成proguard-modu01模块的代码混淆配置,proguard-modu02模块同上配置即可。

proguard-server 启动服务模块的启动类配置

由于代码混淆,会存在大量的类名重名问题,因此需要在springboot启动类中修改 BeanName 生成策略。

方式一:

package com.proguard;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.BeanNameGenerator;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
@SpringBootApplication
public class ProguardServerApplication {
	public static class CustomGenerator implements BeanNameGenerator {
        public String generateBeanName(BeanDefinition definition, BeanDefinitionRegistry registry) {
            return definition.getBeanClassName();
        }
    }
	public static void main(String[] args) {
		 new SpringApplicationBuilder(ProguardServerApplication.class)
         .beanNameGenerator(new CustomGenerator())
         .run(args);
	}
}

方式二:若是maven工程师引用了springfox-boot-starter组件、springfox-*.jar相关组件,会产生异常,重写springboot启动类,如下:

@SpringBootApplication
public class ProguardServerApplication {	
    public static void main(String[] args) {
	   new SpringApplicationBuilder(ProguardServerApplication .class)
        .beanNameGenerator(new ProGuardBeanNameGenerator()).run();
	}
	/**
	 * 代码混淆后,包名、类名会存在重复,重写buildDefaultBeanName方法,获取全限定的类名
	 */
     static class ProGuardBeanNameGenerator extends AnnotationBeanNameGenerator {
	     @Override
	     protected String buildDefaultBeanName(BeanDefinition definition) {
	         return definition.getBeanClassName();
	     }
	  }
}

启动,验证

通过Java反编译工具 查看源代码结果如下图,包名、类名已经重新命名,代表代码混淆已生效。

 proguard-modu01:

proguard-modu02:

启动访问

访问proguard-modu01中接口:

 访问proguard-modu02中接口:

 踩过坑

1. proguard-modu01、proguard-modu02配置混淆后,访问接口提示404。去掉代码混淆恢复正常访问。

解决:在proguard-modu01、proguard-modu02的pom.xml文件中配置保持目录结构:<option>-keepdirectories</option> 

 2. 若是maven工程师引用了springfox-boot-starter组件、springfox-*.jar相关组件,会产生异常。
