GET method is not supported, shows after success log in, how to solve this? - spring

Question

I am working on an administration system, I have HomeController.java:
#Controller
public class HomeController {
#Autowired
private UserRepository userRepository;
#Autowired
private UserService userService;
#GetMapping("/")
public String root() {
return "/home";
}
#GetMapping("/home")
public String home() {
return "/home";
}
#RequestMapping("/login")
public String login() {
return "/login";
}
#RequestMapping("/user")
public String userIndex() {
return "/index";
}
#GetMapping("/profile")
public String currentUser(#ModelAttribute("user") #Valid UserDto userDto, BindingResult result, Model model) {
Authentication loggedInUser = SecurityContextHolder.getContext().getAuthentication();
String email = loggedInUser.getName();
User user = userRepository.findByEmail(email);
String firstName = user.getFirstName();
model.addAttribute("firstName", firstName);
model.addAttribute("email", email);
return "profile";
}
when i try to log in with bad credentials everything works fine and it gives invalid pass or username.
The problem is when i enter the correct Credentials, i get this page:
Here is SecurityConfig.java:
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserService userService;
#Autowired
private UserRepository userRepository;
#Override
protected void configure(final HttpSecurity http) throws Exception {
// #formatter:off
http

.key("uniqueAndSecret")
.userDetailsService(userService);
}
//Beans
#Bean
public PasswordEncoder encoder() {
return new BCryptPasswordEncoder(11);
}
#Bean
public DaoAuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider auth = new DaoAuthenticationProvider();
auth.setUserDetailsService(userService);
auth.setPasswordEncoder(encoder());
return auth;
}
#Bean
public AuthenticationManager customAuthenticationManager() throws Exception {
return authenticationManager();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authenticationProvider());
}
}

Here:
#RequestMapping("/user")
public String userIndex() {
return "/index";
}
you do redirect to index (without '.html' extension), but there is no mapping for index url.
So you can change it to:
return "/index.html";
if you have index.html file in static directory.
