aop:config 中,你的execution 配置的事impl.UserDao,但是下面 ref 引用的事 proUserDao ,把execution  中的impl.UserDao 改成impl.ProUserDao

首先非常感谢您的热心解答,但是我试了试,还是会报同样的错误,我的修改如下:

我觉得的确是aop:config的问题,因为我把config注释掉就不会报错了。
报错如下:

@知新小家: 现在配置文件没有错误;是你的aspectj 错了。没有构造函数;你百度一下怎么写aspectj

悟行 | 园豆:12328 (专家六级) | 2020-05-13 09:09

@知新小家: aspectj  这个class也要在 bean配置文件中配置,加上这个就可以了

悟行 | 园豆:12328 (专家六级) | 2020-05-13 09:13

@悟行: ![]

请问大佬我这个是不是没有引入jar包 我点开发现好多报错的,请问有这个的问题吗?

知新小家 | 园豆:199 (初学一级) | 2020-05-13 10:04

@知新小家: 应该是版本不对
