springboot+mybatis逆向工程啓動報錯

mybatis逆向工程生成pojo，dao，想啓動測試一下，發現啓動報錯，

ERROR 9112 — [ restartedMain] o.m.spring.mapper.MapperFactoryBean

Error while adding the mapper ‘interface
cn.marblog.bwcar.dao.ActivityCarMapper’ to configuration.
org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is ‘cn/marblog/bwcar/dao/ActivityCarMapper.xml’. Cause: java.lang.IllegalArgumentException: Result Maps collection already contains value for cn.marblog.bwcar.dao.ActivityCarMapper.BaseResultMap

起初以爲是沒加註解，但是加上註解也不行，把逆向工程生成的文件刪掉項目可以跑起來，所以應該是生成文件的問題，查了半天發現是有的表重複了，Result Maps collection already contains value for cn.marblog.bwcar.dao.ActivityCarMapper.BaseResultMap

所以在配置文件的 jdbcConnection標籤中加入
<property name="nullCatalogMeansCurrent" value="true"/>
刪除原來的文件， 重新生成一下文件即可。
