I am getting white label error with 404 (not found) while I am loging in - spring-mvc

Question

Here is my code for security configuration, I am getting white label error with 404 (not found) when I mention roles in hasAnyAuthority method, but when I mention only one role in hasAuthority it is working fine. Here I need to know do we need any authentication manager bean or authentication manager builder bean?
#EnableWebSecurity
#Configuration
public class WebSecurityConfig {
#Bean
public UserDetailsService userDetailsService() {
return new UserDetailsServiceImpl();
}
#Bean
AuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
authProvider.setUserDetailsService(userDetailsService());
authProvider.setPasswordEncoder(passwordEncoder());
return authProvider;
}
#Bean
public BCryptPasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
#Bean
SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
http
.cors()
.and()
.csrf().disable()
.authorizeHttpRequests()
.antMatchers("/register").permitAll()
.and()
.authorizeHttpRequests()
.antMatchers("/signin").hasAnyAuthority("ROLE_ADMIN", "ROLE_USER")
.and()
.formLogin()
.permitAll()
.and()
.authenticationProvider(authenticationProvider());
return http.build();
}
}
Below is my controller class, I have not created any HTML pages. I am simply displaying message to check weather it is working or not, but it is not working. While I am mentioning the two roles which is user and admin in hasAnyAuthority and when I hit the /signin URL it is not working.
#RestController
public class UserRegistrationController {
#Autowired
private UserServices userService;
#Autowired
private PasswordEncoder passwordEncoder;
#PostMapping("/register")
public ResponseEntity<User> createUser(#Valid #RequestBody User user) throws Throwable {
String tempEmailID = user.getEmailId();
String encryptedPassword = passwordEncoder.encode(user.getPassword());
user.setPassword(encryptedPassword);
if (tempEmailID != null && !"".equals(tempEmailID)) {
User userObject = userService.fetchUserByEmailId(tempEmailID);
if (userObject != null) {
throw new ResourceNotFoundException("User with " + tempEmailID + " is already exist ");
}
userService.save(user);
}
return new ResponseEntity<User>(user, HttpStatus.CREATED);
}
#GetMapping("/signin")
public String loginPage() {
return "login sucess";
}
}
