Spring Security login with customized form

Question

My Spring security configurations:

@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter{

        @Autowired
        private ClientDetailsService clientDetailsService;

        @Autowired
        public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
            auth.inMemoryAuthentication()
              .withUser("username").password("password")
              .authorities("USER");
        }

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and().csrf().disable();
        }

       ....
}

My Spring boot controllers:

@Controller
@RequestMapping("/")
public class IndexController extends BaseController {

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String login() {
        return "login";
    } 
....
}

Hi, I am attempting to using Spring security with customized login form. My problem is:

1. When I enter the localhost:8080/login The browser doesn't direct to my login.jsp, it just pops out a default form with text boxes to enter username and password.

2. After I enter "username" as username, "password" as password, it returns an authentication failed.

The traceback:

Looks like the anonymous user has not access to /login

http
    .authorizeRequests()
        .antMatchers("/login").anonymous()
        .anyRequest().authenticated()
        .and()
    .formLogin()
        .loginPage("/login")
        .permitAll()
        .and().csrf().disable();

Overmore, looks like you are doing request against your server with the Authorization header for the Basic Authentication.

DEBUG - Basic Authentication Authorization header found for user 'username'
