code 403 no authorization even after putting the correct jwt token

I'm creating an api for use in a pharmacy. When implementing the security, jwt token and filter for using security, an error occurs when validating requests and the token is simply not considered valid. It has an expiration time of 2 hours, the user is allowed to login, I do this via postman, I take the token that appears, I copy and paste it in the authorization validation, I make a protected request in postman and I simply take a forbidden403 . I'm using the post method to make this request, and the baerer Token to send it. In the code, as you can see, it has all the correct configuration for my filter to come before spring's filter and also has the configuration to demonstrate how far the code is running, with a sistem.out with the message("calling filter") What indicates that the code runs until the validation of the token and after the problem. Note: I'm using mysql, springboot 3.0 and java 17. The entire structure of the tables is already created and working, but I can't make any request besides the login after facing this validation error. Follow the code below:
User Entity: #Table(name = "users") #Entity(name = "User") #Getter #NoArgsConstructor #AllArgsConstructor
#EqualsAndHashCode(of ="id") public class User implements UserDetails{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)

throws ServletException, IOException {
var tokenJWT = recuperarToken(request);
System.out.println("Chamando Filter");
if(tokenJWT != null) {
var subject = tokenService.getSubject(tokenJWT);
var usuario = repository.findByLogin(subject);
var authentication = new UsernamePasswordAuthenticationToken(usuario, null, usuario.getAuthorities());
SecurityContextHolder.getContext().setAuthentication(authentication);
System.out.println("Logado na requisição");
}
filterChain.doFilter(request, response);
}
private String recuperarToken(HttpServletRequest request) {
var authorizationHeader = request.getHeader("Authorization");
if( authorizationHeader != null) {
return authorizationHeader.replace("Bearer", "");
}
return null;
}
I login via postman, get the token code and paste it in the authorization to then use that token in some other request that is also protected via spring security.
I hope the request is accepted and released after validating the token in the request header.

How to set up Spring boot 3 security config proper?

I'm trying to integrate the updated Spring Security in my project, instead of using the deprecated extending WebSecurityConfigurerAdapter. I've set up a good system in which the user gets authenticated (User implements UserDetails - I am using Hibernate) and a token gets generated. I get a 200 on this login and receive a token. This authetication part works fine.
Now the problem is that my users have roles (like ADMIN, USER, ...) These roles are added to the generated token. My controllers get the #PreAuthorize annotation. The request cannot pass these annotation and get a forbidden. When I don't use the #PreAuthorize, the requests get validated with the token.

#PreAuthorize("hasAnyRole('USER', 'ADMIN')")
I am making a configuration mistake somewhere, but I cannot seem to find it. Spring docs are very very hard to figure out, but I have been reading them relentlessly. There is also not a lot of clear information on these topics yet. I can find youtube videos tutorials and some related topics, but they only explain small parts, never a full setup.
I have added below my securityConfig, KeyGenerator, Jwks and tokengenerate service. I also just added the Userdetailsimpl and service. I build my userdetailsImpl out of a user with a static build method. It might seem a strange construction but it works, it is because I did the security last and didn't think of it before. Also I added an example of my #Preauthorize.
I am very close and this could be a good example for other users trying to implement this, because I seem not te able to find an example somewhere.Does anyone have experience with setting the Spring Boot 3 security up and can they tell me how I am misconfiguring? Why is my role not getting 'read' by the #PreAuthorize?

Okay so here's the thing, since you're implementing resource server, the class
org.springframework.security.oauth2.server.resource.authentication.JwtGrantedAuthoritiesConverter
is the one responsible for converting your scopes inside jwt token to granted authorities.
Now, this class prepends all the authorities with SCOPE_ prefix.
Since you're using
hasAnyRole('ADMIN', 'USER',...)
this method internally invokes
hasAnyAuthorityName(defaultRolePrefix, roleName)
method with the defaultRolePrefix as ROLE_ and the roleName as your passed value(s).
Internal Implementation:
#Override
public final boolean hasAnyRole(String... roles) {
return hasAnyAuthorityName(this.defaultRolePrefix, roles);
}
#Override
public final boolean hasAnyAuthority(String... authorities) {
return hasAnyAuthorityName(null, authorities);
}
On the other hand, the hasAnyAuthority method makes a call to the same method but with null passed as defaultRolePrefix.
Now since you're using
.oauth2ResourceServer(OAuth2ResourceServerConfigurer::jwt)
in security config, it is using the default AuthenticationConverter for your jwt token which is
org.springframework.security.oauth2.server.resource.authentication.JwtAuthenticationConverter
which further invokes
org.springframework.security.oauth2.server.resource.authentication.JwtGrantedAuthoritiesConverter
As per the implementation in JwtGrantedAuthoritiesConverter, all the scopes in your jwt token are prefixed by SCOPE_ as I mentioned earlier.
Now assuming your granted authorities return ADMIN as one of the roles. Once you add it to your scope in jwt, the default converter will return SCOPE_ADMIN as an Authority and similarly if you return ROLE_ADMIN in the scope, it will be converted to SCOPE_ROLE_ADMIN by default.
The JwtAuthenticationConverter class returns an instance of
org.springframework.security.oauth2.server.resource.authentication.JwtAuthenticationToken
So, it can be fixed in following ways:
Either, use hasAnyAuthority to check the authorities by appending SCOPE_ to the role names you have set in scope.
If your role name is ADMIN or ROLE_ADMIN you should use
#PreAuthorize("hasAnyAuthority('SCOPE_ADMIN')")
#PreAuthorize("hasAnyAuthority('SCOPE_ROLE_ADMIN')")
and so on.
If you want to use hasAnyRole check then you must use
#PreAuthorize("hasAnyAuthority('ROLE_SCOPE_ADMIN')")
#PreAuthorize("hasAnyAuthority('ROLE_SCOPE_ROLE_ADMIN')")
for ADMIN and ROLE_ADMIN values respectively.
Or, Implement a custom Authority Converter and pass it to the oauth2ResourceServer in security config as follows,
Example Custom Converter
import org.springframework.core.convert.converter.Converter;
import org.springframework.security.oauth2.jwt.Jwt;
import org.springframework.stereotype.Component;
import java.util.Collections;
#Component
public class JwtCustomAuthoritiesConverter implements Converter<Jwt, Collection<GrantedAuthority>> {
#Override
public Collection<GrantedAuthority> convert(Jwt jwt) {
Collection<GrantedAuthority> grantedAuthorities = new ArrayList<>();
Collection<String> splitScopes = Arrays.asList(jwt.getClaim("scope").split(" "));
for (String authority : splitScopes) {
grantedAuthorities.add(new SimpleGrantedAuthority(authority));
}
return grantedAuthorities;
}
}
Then update your spring security config as:
#Bean
JwtCustomAuthoritiesConverter jwtCustomAuthoritiesConverter;
#Bean
JwtAuthenticationConverter jwtAuthenticationConverter(){
JwtAuthenticationConverter jwtAuthenticationConverter = new JwtAuthenticationConverter();
jwtAuthenticationConverter.setJwtGrantedAuthoritiesConverter(jwtCustomAuthoritiesConverter);
return jwtAuthenticationConverter;
}
...
http.oauth2ResourceServer((oauth2) ->
oauth2.jwt((jwt) -> jwt.jwtAuthenticationConverter(jwtAuthenticationConverter()))
...
With the second option you can use your role names the way you want to in jwt token and the
hasAnyRole('ADMIN')
check should get ROLE_ADMIN for ADMIN scope instead of ROLE_SCOPE_ADMIN which is the case now.

Built in Spring-Boot BCrypt matches method doesn't work

I have a UserController that receives a UserDTO and creates/updates the user in the DB. The problem I'm getting is that I also have a login, and when I insert the username and password on the login form, I always get the 'Wrong Password.' exception, despite the credentials being correctly inserted.
One thing I suspect is that BCrypt is to blame, since due to the fact that it generates random salt while encoding, maybe, just maybe, the cipher text ends up being different and stuff, which is weird, since I assume that it should work. I want to know how can I fix this problem of the hashing being different & not being able to validate the userCredentials
I have tried for example encoding the received password and using the matches method via my autowired passwordEncoder, and I'm using my own authProvider.
Here's the code, let me know if you need anything else.
CustomAuthProvider.java
#Service
public class CustomAuthProvider implements AuthenticationProvider {
private final UserServiceImpl userServiceImpl;
private final BCryptPasswordEncoder passwordEncoder;
#Autowired
public CustomAuthProvider(UserServiceImpl userServiceImpl, BCryptPasswordEncoder passwordEncoder) {
this.userServiceImpl = userServiceImpl;
this.passwordEncoder = passwordEncoder;
}
#Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
String username = authentication.getName();
String password = authentication.getCredentials().toString();
UserDetails userDetails = userServiceImpl.loadUserByUsername(username);
if (!passwordEncoder.matches(password, userDetails.getPassword())) { //The problem is here evidently.
throw new BadCredentialsException("Wrong password.");
}
return new UsernamePasswordAuthenticationToken(userDetails, password, userDetails.getAuthorities());
}
#Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
Also, here's the loadUserByUsername method:
UserServiceImpl.java
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
UserDTO user = this.getUserByUsername(username);
User anUser = convertToUser(user);
ModelMapper modelMapper = new ModelMapper();
return modelMapper.map(anUser,UserPrincipal.class);
}
}
And here is the save method I use to save and update users, as well as the LoginController;
#Override
public void save(UserDTO user) {
User aUser = this.convertToUser(user);
aUser.setPassword(passwordEncoder.encode(aUser.getPassword()));
this.userRepository.save(aUser); }
LoginController.java:
#RestController
public class LoginController{
private final CustomAuthProvider providerManager;
#Autowired
public LoginController(CustomAuthProvider providerManager) {
this.providerManager = providerManager;
}
#GetMapping("/login")
public String login() {
return "login";
}
#PostMapping("/login")
public String login(#RequestParam("username") #NotBlank String username,
#RequestParam("password") #NotBlank String password, Model model) {
if(username == null || password == null) { //This is probably not necessary
model.addAttribute("error", "Invalid credentials");
return "login";
}
try {
Authentication auth = providerManager.authenticate(
new UsernamePasswordAuthenticationToken(username, password)
);
SecurityContextHolder.getContext().setAuthentication(auth);
return "redirect:/notes";
} catch (AuthenticationException e) {
model.addAttribute("error", "Invalid credentials");
return "login";
}
}
}
UserPrincipal.java
#Data
public class UserPrincipal implements Serializable , UserDetails {
int id;
private String username;
private String password;
private Date accountCreationDate = new Date();
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return null;
}
#Override
public boolean isAccountNonExpired() {
return false;
}
#Override
public boolean isAccountNonLocked() {
return false;
}
#Override
public boolean isCredentialsNonExpired() {
return false;
}
#Override
public boolean isEnabled() {
return false;
}
}
UserDTO.java
#Data
public class UserDTO implements Serializable {
int id;
private String username;
private String password;
private List<Note> notes = new ArrayList<>();
}
I read several issues related to this topic, like
Spring Boot PasswordEncoder.matches always false
Spring Security - BcryptPasswordEncoder
Inconsistent hash with Spring Boot BCryptPasswordEncoder matches() method
How can bcrypt have built-in salts?
Decode the Bcrypt encoded password in Spring Security to deactivate user account
but none of those helped me solve my issue and there was no real solution to the problem since most of them don't even have an accepted answer.
EDIT: Found out that the 'matches' method only works if I insert the hashed password, not the raw password.

Found out my mistake:
The setPassword method in the User class was re-hashing the hashed password which was already being hashed on the save method, thus the modelMapper.map() method used that setPassword method, therefore the passwords never matched and the password I got from the user class never matched the actual password I could see on my database.

DELETE and PUT endpoints don't work after implementing Spring Security

I'm currently developing a fullstack web application with a React Frontend and Spring Boot backend. I've implemented Spring security and JWT for authentication, but I can't access my API endpoints (see Controller) ever since. I've managed to access the GET request endpoints, but none of the PUT or DELETE requests seem to work despite logging in on the backend before starting a request.
I've seen that disabling csrf solved the problem in another post, but I've never enabled it anyway, so that wouldn't do the trick for me.
WebSecurityConfig file:
#Configuration

#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override

http
.csrf().disable()
.authorizeRequests()
.antMatchers("/api/v*/registration/**")
.permitAll()
.anyRequest()
.authenticated().and()
.formLogin();
}
Controller (REST API)
#RestController
#RequestMapping(path = "/question")
#CrossOrigin("*")
public class QuestionController {
private final QuestionService questionService;
#Autowired
public QuestionController(QuestionService questionService) {
this.questionService = questionService;
}
#CrossOrigin("*")
#GetMapping("/all")
public ResponseEntity<List<Question>> getAllQuestions() {
List<Question> questions = questionService.findAllQuestions();
return new ResponseEntity<>(questions, HttpStatus.OK);
}
#CrossOrigin("*")
#GetMapping("/find/{id}")
public ResponseEntity<Question> getQuestionById(#PathVariable("id") Long id) {
Question question = questionService.findQuestionById(id);
return new ResponseEntity<>(question, HttpStatus.OK);
}

So apart from requests coming to /api/v*/registration/** others are secured. What does that mean?, it means until you have authorized users having authorized roles cannot access any other endpoint. So you need to do some things like:
implement UserDetails of package org.springframework.security.core.userdetails and implement the method:
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return roles == null?null:roles.stream().map(m->new SimpleGrantedAuthority(m.getAuthority())).collect(Collectors.toSet());
}
Add roles to your entity class:
#OneToMany(fetch = FetchType.EAGER,cascade = CascadeType.PERSIST)
#JoinTable(
name = "user_role",
joinColumns = #JoinColumn(
name = "user_id",
referencedColumnName = "id"
),
inverseJoinColumns = #JoinColumn(
name = "role_id",
referencedColumnName = "id"
))
private List<Role> roles;
Use those roles in your endpoint:
#PreAuthorize(hasRole('ROLE_role_name'))
#GetMapping(path = EndPoint.PATIENT_HOME, consumes = "application/json", produces = "application/json")
public ResponseEntity<YourDTO> Home(Principal principal) {
return new ResponseEntity<YourDTO>(yourDTO, HttpStatus.OK);
}

Postman Request
{"studentRequest":[{"user":"admin","duration":19336}]}

your request body should be like this:
{"user":"admin","duration":19336}
because you are getting StudentRequest as RequestBody and it means you should send StudentRequest internal properties not containing StudentRequest it self in request ,
second problem is that your RequestBody contains singular object not array .

According to what you've given us your request should actually be
{
"user": "admin",
"duration": 19336
}
If you want to provide multiple student requests at once (within an array), then you're StudenRequest class should look somewhat like this:
public class StudentRequest {
List<StudentR>;
// Getter and Setter or not in case you use lombok
class StudenR {
String user;
Long duration ;
}
}
