最后发现，Entity 当时自动导入的是 jakarta 包下的，而我用的是 javax 包的。首先，报错没有 TableGenerators 这个类，去 Jar 包看了一下还真没有。加 @Entity ，@EntityScan 这些全试过了，都没解决。真的哭死，全网所有报错都试过，都不是我的问题。

发现报错时在网上查找解决办法，但都是说：JPA无法识别某个实体类，认为它不是一个被管理的实体类型，让检查注解@Table、@Entity。，于是尝试把实体类的位置移动到同层级的entity文件夹，重启果然可以了。后面以为是xml的注解干扰了，于是去掉后重新启动还是同样的报错。代码如图：很明显是没有错的。最后又在网上查询，说是。
