Spring OAuth2 "Full authentication is required to access this resource"

Question

I'm trying to use Spring OAuth2 for my rest app. But looks like I made a mistake and I can find where I did it. The flow should be: 1. get token from /oauth/token with username and password 2. make request to /security with provided token

MethodSecurityConfig:

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {

    @Autowired
    private SecurityConfiguration securityConfig;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }
}

OAuth2ServerConfig:

@Configuration
public class OAuth2ServerConfig {

    private static final String RESOURCE_ID = "nessnity";

    @Configuration
    @Order(10)
    protected static class UiResourceConfiguration extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                    .requestMatchers().antMatchers("/security")
                    .and()
                    .authorizeRequests()
                    .antMatchers("/security").access("hasRole('USER')");
        }
    }

    @Configuration
    @EnableResourceServer
    protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

        @Override
        public void configure(ResourceServerSecurityConfigurer resources) {
            resources.resourceId(RESOURCE_ID);
        }

        @Override
        public void configure(HttpSecurity http) throws Exception {
            http
                    .requestMatchers().antMatchers("/security/")
                    .and()
                    .authorizeRequests()
                    .antMatchers("/security").access("#oauth2.hasScope('read')");
      }

    }

    @Configuration
    @EnableAuthorizationServer
    protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

        @Autowired
        private TokenStore tokenStore;

        @Autowired
        private UserApprovalHandler userApprovalHandler;

        @Autowired
        private AuthenticationManager authenticationManager;

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            clients.inMemory()
                    .withClient("my-client")
                    .resourceIds(RESOURCE_ID)
                    .authorizedGrantTypes("client_credentials")
                    .authorities("ROLE_CLIENT")
                    .scopes("read")
                    .secret("password")
                    .accessTokenValiditySeconds(60);
        }

        @Bean
        public TokenStore tokenStore() {
            return new InMemoryTokenStore();
        }

        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            endpoints
                    .tokenStore(tokenStore)
                    .userApprovalHandler(userApprovalHandler)
                    .authenticationManager(authenticationManager);
        }

        @Override
        public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
            oauthServer.realm("sparklr2/client");
        }

    }

    protected static class Stuff {

        @Autowired
        private ClientDetailsService clientDetailsService;

        @Autowired
        private TokenStore tokenStore;

        @Bean
        public ApprovalStore approvalStore() throws Exception {
            TokenApprovalStore store = new TokenApprovalStore();
            store.setTokenStore(tokenStore);
            return store;
        }

        @Bean
        @Lazy
        @Scope(proxyMode=ScopedProxyMode.TARGET_CLASS)
        public SparklrUserApprovalHandler userApprovalHandler() throws Exception {
            SparklrUserApprovalHandler handler = new SparklrUserApprovalHandler();
            handler.setApprovalStore(approvalStore());
            handler.setRequestFactory(new DefaultOAuth2RequestFactory(clientDetailsService));
            handler.setClientDetailsService(clientDetailsService);
            handler.setUseApprovalStore(true);
            return handler;
        }
    }

}

SecurityConfiguration:

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("root")
                .password("password")
                .roles("USER");
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/oauth/uncache_approvals", "/oauth/cache_approvals");
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .anyRequest().hasRole("USER");
    }
}

Problem: when I tried to get token

curl --user root:password --data "grant_type=client_credentials" http://localhost:8080/oauth/token

I got message:

{"error":"invalid_client","error_description":"Bad client credentials"}

The second question is how to pass username/password in the url params like /oauth/token?username=root&password=password ?

Thanks.

UPDATE

I decided to start from scratch and use xml configuration.

The following configuration works perfect:

Answer 1

I have faced similar for me it worked after doing the following change

In your AuthorizationServerConfiguration class replace

        @Override
        public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
            oauthServer.realm("sparklr2/client");
        }

with the below code

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        //oauthServer.realm("sparklr2/client");
        oauthServer.allowFormAuthenticationForClients();
    }

and request should like

/oauth/token?grant_type=password&scope=read+write&client_id=yourclientId&client_secret=secret&username=userName&password=pwd
