按照readme对我的jar包进行加密，发现加密后在反编译还是能看到源码，运行时还会报错 #60

按照官方教程，一步步进行了加密。 结果成功后在反编译加密后的jar，还是能看到源码，不知道什么原因？ 试着用xjar java -jar ***-encrypted.jar 运行后报错，为什么我这里会出现这种问题？是我的环境有问题吗？

也遇到这个InvocationTargetException问题，这里我用到了反射

默认情况下，即没有提供过滤器的时候，对于Spring Boot JAR包只加密本项目即 BOOT-INF/classes/ 下的资源， 而对于普通JAR则除了META-INF/MANIFEST.MF 之外的所有资源。

源码没有被加密可能是这个原因。报错我没遇到。

应该就是因为springboot的jar包内部包含了第三方依赖jar包，才引起的错误
