------------------------------------
Hi jiatao Tao:
I meet this exception too, so what operation will make
`!userService.loadUserByUsername(username).equals(user)` then update user
during query through JDBC?
And ManagerUser compare every field in it to judge equality, it's necessary?
If you find any mistake or misunderstanding, please feel free to correct me.
Best regards
