Failed to introspect Class [xxx.xxx] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]

错误提示

Error creating bean with name ‘xxx.xxx’: Lookup method resolution failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [xxx.xxx] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]

查找过程

1、点击蓝色路径，可以跟到类里
2、切换到其他没引入这个包的分支，可以启动。确定是包的问题
3、利用Maven Helper解决jar包冲突，未能解决
4、进入类中发现RedisTools类可以跟进去，AuthorityAggregateRootApi跟不进去。确定是缺少AuthorityAggregateRootApi所依赖的包导致

5、剩下方法很多了，问问同事这个包在哪里。如果不是自定义类可以搜索所属的包。我是打开其他可以启动项目的AuthorityTools类跟进去查找所属包的位置

结论

缺少引入必要的包
