My code was working fine until using #EnableJpaRepository. Before that I used it till UserController's #GetMapping, and it was taking me to user.jsp. But from the moment I am using JPA, its not working, I searched the solution but everywhere , it was to use spring-tx, and I did that, its even in my lib, but still can't figure it out. So please if anyone can help me.
