Description

Mapper interfaces cannot have the same name as the XML mapped to them.

For example, an XML file mapper/PersonMapper.xml cannot be linked to a class named mapper.PersonMapper.

Doing so leads to an exception :
org.apache.ibatis.exceptions.IbatisException:

1. 1. 1. Error building SqlSession.
      2. The error may exist in mapper/PersonMapper.xml
      3. Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.lang.RuntimeException: Error parsing Mapper XML. Cause: java.lang.IllegalArgumentException: Mapped Statements collection already contains value for mapper.PersonMapper.get
