Solution: I just modified the mapper, and some places are wrong, so check it carefully.
The mapper in the error message is not necessarily the mapper with the actual error.
An error will be reported at startup, and the mapper may have problems with parameterType, resultType, etc. For example, the resultMap is written as resultType; or the class referenced in the mapper is inconsistent with the java file; or the execution id of the mapper is inconsistent with the java class of the mapper, etc.
