Spring Boot Login 401 unauthorized Postman - spring-boot

Question

In my spring boot application I have one endpoint for login and one for signup. When signing up everything is fine, the new user is created correctly.
Then if I try to login with the just-created credentials, Postman returns a 401 Unauthorized error. These are my controller methods (first login then signup):
#PostMapping(PathConstants.LOGIN_ACTION)
#ApiOperation("Login into Helios administrational console.")
#Override
public ResponseEntity<?> autenticate(#Valid #RequestBody LoginRequest request) {
System.out.println("Login");
System.out.println("Us psw " + request.getUsername() + " " + request.getPassword());
Authentication auth = authManager
.authenticate(new UsernamePasswordAuthenticationToken(request.getUsername(), request.getPassword()));
System.out.println("Auth " + auth.toString());
SecurityContextHolder.getContext().setAuthentication(auth);
String token = jwtProvider.generateToken(auth);
System.out.println("TOken " + token);
return ResponseEntity.ok(new JwtAuthResponse(token));
}
#PostMapping(PathConstants.SIGNUP_ACTION)
#ApiOperation("Signup to Helios administrational console.")
#Override
public ResponseEntity<?> register(#Valid #RequestBody SignUpRequest request) {
sysdataUserService.createNewSysdataUser(request);
return ResponseEntity.ok().body(new DashboardResponse(true, "New sysdata user registered successfully."));
}
I get on console "login" and "Us psw" with the correct data, but after
Authentication auth = authManager
.authenticate(...)
nothing is printed. I'm thinking is a problem with the authenticate method, but what problem could be? And how can I solve it? These are my security configurations:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable().authorizeRequests()
.antMatchers(HttpMethod.POST, PathConstants.USER_AUTH +"/**", PathConstants.HELIOS+"/dashboard/**").permitAll()
.antMatchers(HttpMethod.GET, "/"+PathConstants.PROCESS_DEFINITION+"/**").permitAll()
.antMatchers(HttpMethod.POST, "/"+PathConstants.PROCESS_DEFINITION+"/**").permitAll()
.antMatchers(HttpMethod.GET, "/"+PathConstants.PROCESS_INSTANCE+"/**").permitAll()
.antMatchers(HttpMethod.POST, PathConstants.LOGIN_ACTION).permitAll()
//.anyRequest().authenticated()
.anyRequest().permitAll()
.and()
.exceptionHandling().authenticationEntryPoint(jwtAuthEntryPoint).and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
// custom jwt filter.
http.addFilterBefore(jwtAuthFilter(), UsernamePasswordAuthenticationFilter.class);
}
I've added .antMatchers(HttpMethod.POST, PathConstants.LOGIN_ACTION).permitAll() to try if this way it works, but still I had 401. Then I have these WebMvcConfigurations for Cors policy:
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/api/**")
.allowedOrigins("*")
.allowedMethods("HEAD", "OPTIONS", "GET", "POST", "PUT", "PATCH", "DELETE")
.allowedHeaders("Content-Type", "X-Requested-With", "accept", "Origin", "Access-Control-Request-Method",
"Access-Control-Request-Headers")
.exposedHeaders("Access-Control-Allow-Origin", "Access-Control-Allow-Credentials").maxAge(MAX_AGE);
//.allowCredentials(true).maxAge(MAX_AGE);
}
What is wrong?
All the other endpoints work correctly, but not login.
