the connection with database is good, i can list users as well Thanks for reading all this and sorry for bad english and mistakes, have a good day!

CodePudding user response：

You have doubly declared userDetailsService with the same name,

First:

   @Bean
    @Override
    public UserDetailsService userDetailsService() {
        return super.userDetailsService();
    }

Second:

@Service("userDetailsService")
public class UserServiceImpl implements UserService, UserDetailsService  {

It may cause the problem. You should have only one instance of userDetailService.

CodePudding user response：

In your SecurityConfig Can you try removing

    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    @Override
    public UserDetailsService userDetailsService() {
        return super.userDetailsService();
    }

And changing the implementation for

 @Override
    @Autowired
    public void configure(AuthenticationManagerBuilder auth) throws Exception{
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

to

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception{
        auth.userDetailsService(new UserServiceImpl()).passwordEncoder(passwordEncoder());
    }
