问题背景

使用mybatis时报错，不能找到statement的sql语句，说明xml文件没有映射成功，发现原来是没有配置mapper.xml的文件路径

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.yg.mybatisgenerator.dao.mysql.GeneratorRecordMapper.insert

解决方案

1 在application的配置中添加mapper.xml的文件路径，根据自己的路径进行填写即可

mybatis:
  mapper-locations: mapper/mysql/*Mapper.xml
