EnableResourceServer breaks oAuth2 authorization server - spring-boot

Question

I implemented oAuth2 authorization server using Spring Boot version 1.5.2.RELEASE. The authorization server supports implicit flow. With the WebSecurityConfig below the login form (http://localhost:8200/login) works well.
#Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private JpaUserDetailsService userDetailsService;
#Bean
#Override
public UserDetailsService userDetailsServiceBean() throws Exception {
return userDetailsService;
}
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
#Bean
public AuthenticationProvider authenticationProvider() throws Exception {
DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
provider.setUserDetailsService(userDetailsServiceBean());
provider.setPasswordEncoder(passwordEncoder());
return provider;
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return new ProviderManager(singletonList(authenticationProvider()));
}
#Override
public void configure(WebSecurity web) {
web.ignoring()
.antMatchers("/")
.antMatchers("/docs/**")
.antMatchers("/swagger/**")
.antMatchers("/token/**")
.antMatchers("/v2/*")
.antMatchers(HttpMethod.OPTIONS, "/**");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests().antMatchers("/login**").permitAll().anyRequest().authenticated().and()
.formLogin().loginPage("/login").permitAll().and()
.logout().permitAll();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
}
I want resource server be a part of the same application. The purpose is I need a /me endpoint that will provide me details of logged in user and endpoints for managing users. But as soon as I add ResourceServerConfig annotated with EnableResourceServer below I start getting an error "Full authentication is required to access this resource" when I request http://localhost:8200/login.
#Configuration
#EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
public static final String RESOURCE_ID = "proclaim-auth";
#Autowired
private ResourceServerTokenServices tokenServices;
#Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
resources
.resourceId(RESOURCE_ID)
.tokenServices(tokenServices);
}
#Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/api/ **").authenticated();
}
}
I suspect that resource server security chain precedes authorization server security chain. I tried to annotate WebSecurityConfig with annotation Order but it did not fix my problem:
#Configuration
#Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
...
}
What am I doing wrong? Please advise.
Thanks in advance!
EDIT 1
I added method configure(HttpSecurity http) into ResourceServerConfig and changed value of Order annotation to -1 on WebSecurityConfig. Now the security filted defined in WebSecurityConfig is applied and the one defined in ResourceServerConfig is ignored. So when I call /me endpoint with valid token I'm redirected to login page.

Answer 1

The cause of the problem was wrong configuration of http security in the ResourceServerConfig class. The correct configuration is as follows:
#Override
public void configure(HttpSecurity http) throws Exception {
http
.requestMatchers().antMatchers("/api/**").and()
.authorizeRequests().anyRequest().authenticated();
}
The requestMatchers will ensure that only requests on paths starting with "/api/" will be processed by this security chain. All other requests will be passed to the security chain defined in the WebSecurityConfig class. I was missing this in my config so all requests were processed by the ResourceServerConfig security chain and none request reached the WebSecurityConfig security chain.
