Spring security oauth2 always returning 403 - spring-boot

Question

I have a Spring boot app serving Rest endpoints which I'm securing using Spring security and Oauth2.
I want to secure all my endpoints except the endpoints used to authenticate, to create an account or some info stuff.
The security configuration is like this :
#Configuration
#EnableAuthorizationServer
public class OAuth2Config extends AuthorizationServerConfigurerAdapter {
#Autowired
private AuthenticationManager authenticationManager;
#Autowired
private MongoTokenStore tokenStore;
#Override
public void configure(final AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
oauthServer.tokenKeyAccess("permitAll()").checkTokenAccess("isAuthenticated()");
}
#Override
public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {
//clients.withClientDetails(clientDetailsService);
clients.inMemory().withClient("app").secret("password")
.accessTokenValiditySeconds(30000).authorizedGrantTypes("password", "refresh_token")
.refreshTokenValiditySeconds(300000000)
.scopes("read");
}
#Override
public void configure(final AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.tokenStore(tokenStore()).authenticationManager(authenticationManager)
.pathMapping("/oauth/confirm_access", "/access_confirmation");
}
#Bean
public TokenStore tokenStore() {
return this.tokenStore;
}
}
#Configuration
#EnableResourceServer
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserRepository userRepository;
#Autowired
private SecurityContextService securityContextService;
#Autowired
private MongoTemplate mongoTemplate;
#Bean
public MongoUserDetailsManager mongoUserDetailsManager() throws Exception {
return new MongoUserDetailsManager(userRepository, securityContextService, authenticationManagerBean(), mongoTemplate);
}
#Override
protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.parentAuthenticationManager(authenticationManagerBean())
.userDetailsService(mongoUserDetailsManager());
}
#Override
#Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Override
protected void configure(final HttpSecurity http) throws Exception {
http.
authorizeRequests()
.antMatchers("/login", "/oauth/authorize", "/oauth/token", "/server/version", "/clients/register").permitAll()
.and().csrf().disable()
.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.formLogin()
.disable();
}
}
I can access to token endpoint to get my access_token, but I want to access to other secured endpoints using this access_token (by adding the Authorization:Bearer {access_toke} to the header), I always get HTTP 403.
Did I miss something? I'm not supposed as authorized if I add the Authorization header?
My Controllers are only annotated with these #RestController, #CrossOrigin
and #RequestMapping("/url")

There are 2 types of security configurations in case of OAuth security(as far as urls security is concerned) in Spring.
1. Basic Security Configuration
This class should implement WebSecurityConfigurerAdapter. It will handle all those requests coming without "Bearer" token type(urls that shouldn't be oauth protected).
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserRepository userRepository;
#Autowired
private SecurityContextService securityContextService;
#Autowired
private MongoTemplate mongoTemplate;
#Bean
public MongoUserDetailsManager mongoUserDetailsManager() throws Exception {
return new MongoUserDetailsManager(userRepository, securityContextService, authenticationManagerBean(), mongoTemplate);
}
#Override
protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.parentAuthenticationManager(authenticationManagerBean())
.userDetailsService(mongoUserDetailsManager());
}
#Override
#Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Override
protected void configure(final HttpSecurity http) throws Exception {
http.
authorizeRequests()
.antMatchers("/login", "/oauth/authorize", "/oauth/token", "/server/version", "/clients/register").permitAll()
.and().csrf().disable()
.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.formLogin()
.disable();
}
}
2. Resource Server Configuration(OAuth Specific)
This class is responsible for handling all those requests coming with authorization header of type Bearer. It should be extended from ResourceServerConfigurerAdapter class. Here you should mention all those urls with security configurations that you like to be oauth protected.
#Configuration
#EnableResourceServer
public class OAuthResourceServerConfig extends ResourceServerConfigurerAdapter {
#Override
public void configure(HttpSecurity http) throws Exception {
http.requestMatchers().antMatchers("/resources-to-be-protected/**").and().authorizeRequests()
.antMatchers("/resources-to-be-protected/**").access("#oauth2.isClient()");
}
}
