在项目中遇到一个错误，当尝试创建名为'xxx.xxx'的Bean时，出现了 Lookupmethod resolution failed 错误，原因是缺少 AuthorityAggregateRootApi 类所依赖的包。通过检查代码、切换分支、使用MavenHelper排除jar包冲突等步骤，确定问题源于未引入必要的包。尽管RedisTools类可用，但AuthorityAggregateRootApi类无法正常加载，进一步证实了这一结论。解决方案是查找并引入缺失的依赖包。

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]
在这里插入图片描述

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
