    Hi Ramesh, Kundan Here
    I followed your tutorial for Spring Security Hibernate Database Authentication - UserDetailsService.I followed the exactly same step that you followed in your you tube channels and java guides blogs. I faced one exception which is "org.springframework.security.authentication.InternalAuthenticationServiceException: query did not return a unique result: 3; nested exception is javax.persistence.NonUniqueResultException: query did not return a unique result: 3". I am providing the right user name & password in jsp login page but the login page is fetching the error message "invalid user name & password".Please ramesh help me.looking for your reply.
