![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzY0OTk5Nw_size_16_color_FFFFFF_t_70]ps：这是一个可能是个小众问题的解决方案。  
我是用了spring security框架进行登录安全验证。  
现象：登录失败或者登陆成功但之后访问所有资源都有403 Forbidden。

*  首先检查sql语句是否有问题，我在plsql中试了，没问题。
 *  然后检查错误日志信息，没有映射：*发现类名写错*了：I\_Permission ——I\_PermissionDao,改过来就完事了。

Caused by: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for cn.neu.ssm.dao.I_Permission.findByRoleId

*  细心一点：路径类名方法名不要写错了
