如图，出现下面错误代码！
记住一定不要从上面开始找错误，先从出错提示信息的下面去找：

提示的大概意思是：Result Maps collection already contains value for org.gwj.ssm.dao.CompanyMapper.BaseResultMap
Result Maps中已经包含了一个BaseResultMap，产生的原因是因为使用Mybatis generator逆向工程在生成代码的时候，如果原先的Company.xml文件没有删除，生成的文件不会覆盖，而是追加在该文件中，所以出现重复。
【Result Maps collection already contains value for org.gwj.ssm.dao.CompanyMapper.BaseResultMap】解决方法：删掉重复部分即可。
