Starting this is due to a low-level error, which has the following configuration in Applicationcontext.xml:

1 <Beanclass= "Org.mybatis.spring.mapper.MapperScannerConfigurer">2          < Propertyname= "Basepackage"value= "Com.xxx.xxx.dao.**.*" />3          < Propertyname= "Sqlsessionfactorybeanname"value= "Sqlsessionfactory" />4 </Bean>

The value of Basepackage should be the name of the specified package and the file name I specified.

Change to the following configuration, compile normal pass:

1 <Beanclass= "Org.mybatis.spring.mapper.MapperScannerConfigurer">2          < Propertyname= "Basepackage"value= "Com.xxx.xxx.dao" />3          < Propertyname= "Sqlsessionfactorybeanname"value= "Sqlsessionfactory" />4 </Bean>
