Mybatis uses annotations to report reflection exceptions on the mapper interface

Annotation with Mybatis is to report reflection exception

Re-enter debugging, and then find that the two fields commentId and commentCount are not parsed and cannot be obtained from metaObject

Solution:

Add the param annotation to the parameters of the interface

If the interface is a parameter, it will not report an error. When there are multiple parameters, mybatis needs to specify the fill attribute corresponding to each parameter.
