Maven项目使用mybatis报错 org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

maven项目使用mybatis时,找不到mapper文件(.xml) 错误信息提示: 项目可以正常运行,但是在有请求到达服务器时(有访问数据库的请求),会出现报错!! 错误原因: mybatis没有找到对应的请求调用持久层的方法 查错方法: 首先检查target-->classes文件夹被dao层文件夹内是否有对应mapper.xml文件,如果有xml文件,则一般是配置文件出现的错误,如果没有xml类型的文件,则是没有拷贝资源文件的原因.下面是对应的解决方法. 1.名称不一致问题 排查步骤:
