Spring Security区分大小写

Question

MySql数据库区分大小写，在休眠状态下一切正常，数据库中的表名与我的类相同。 但是在Spring Security上，默认身份验证不能很好地工作，使用表名的首字母小写而不是大写来构建SQL。 有什么方法可以使Spring安全性像休眠状态一样理解大写吗？ 还是只需要将表名更改为大写字母就需要构建自定义身份验证？

我想您使用JdbcDaoImpl （通过jdbc-user-service元素）。 如果是这样，则可以为默认查询提供自己的SQL。

<jdbc-user-service 
    users-by-username-query="select username, password, enabled from Users where username = ?" 
    authorities-by-username-query="select username, authority from Authorities where username = ?" 
/>
