Result Maps Collection already contains value for COM.JKW100.MYBATIS.MAPPER.PATIENTMAPPER.BASERESULTMAP See this because the name of the Mapper.xml file in the ID is baseresultmap duplicate remove duplicate resolve issue

When using MyBatis reverse engineering to automatically generate Mapper.xml, if you accidentally run more than once, then the code in the Mapper.xml file will have one more copy, which will cause the same ID to be two or more and the same file will not be generated more.
