关于nested exception is org.apache.ibatis.reflection.ReflectionException报错问题

       在实现项目的添加功能时,调试过程中报500错误,错误内容如下:

20:13:43.154 ERROR 34144 --- [nio-8088-exec-4] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'bridge_name' in 'class com.muh.entity.BridgeEntity'] with root cause

       根据错误提示,我首先想到是不是因为实体类与DAO层属性不一致造成的,去Dao层一看,果然是这个原因,实体类是横线间隔的形式,在Mapper.xml文件中的sql语句中写成了驼峰表达式,它当然无法在实体类中匹配了,改过来后正常运行!以后还是要细心一些,注意一些小细节。
