I am struggling to do this simple thing in Spring: Redirecting to the Login page when the access token expires.
I have:
- a Edge Server (Zuul) for routing.
- a OAuth2 authorization / authentication server.
- a Resource Server that serves static files.
For specific security reasons I do not want any refresh token, when my TOKEN expires I want the user to login again.
In my understanding the Resource Server should be the one handling this mechanism (correct me if I am wrong).
I have been trying different unsuccessful approaches:
- Adding a filter After OAuth2AuthenticationProcessingFilter and check for Token validity and sendRedirect
- Adding a custom OAuth2AuthenticationEntryPoint to my application (extending ResourceServerConfigurerAdapter)
- Adding .exceptionHandling() with a custom handler / entry point.
Below my security configurations.
Auth Server Security Config:
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerOAuthConfig extends AuthorizationServerConfigurerAdapter {
....
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints
.authenticationManager(this.authenticationManager)
.accessTokenConverter(accessTokenConverter())
.approvalStore(approvalStore())
.authorizationCodeServices(authorizationCodeServices())
.tokenStore(tokenStore());
}
/**
* Configure the /check_token endpoint.
* This end point will be accessible for the resource servers to verify the token validity
* @param securityConfigurer
* @throws Exception
*/
@Override
public void configure(AuthorizationServerSecurityConfigurer securityConfigurer) throws Exception {
securityConfigurer
.tokenKeyAccess("permitAll()")
.checkTokenAccess("hasAuthority('ROLE_TRUSTED_CLIENT')");
}
}
@Configuration
@Order(-20)
public class AuthorizationServerSecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger log = LoggerFactory.getLogger(AuthorizationServerSecurityConfig.class);
@Autowired
private DataSource oauthDataSource;
@Autowired
private AuthenticationFailureHandler eventAuthenticationFailureHandler;
@Autowired
private UserDetailsService userDetailsService;
@Autowired
public void globalUserDetails(AuthenticationManagerBuilder auth) throws UserDetailsException {
try {
log.debug("Updating AuthenticationManagerBuilder to use userDetailService with a BCryptPasswordEncoder");
auth.userDetailsService(userDetailsService()).passwordEncoder(new BCryptPasswordEncoder());
} catch (Exception e) {
throw new UserDetailsException(e);
}
}
@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
public UserDetailsService userDetailsService() {
return this.userDetailsService;
}
@Override
protected void configure(final HttpSecurity http) throws Exception {
log.debug("Updating HttpSecurity configuration");
