This has the result of any user that makes a request with the "Authorisation" header being able to access all resources. And users without the Authorisation header cannot request a token to be used.
I've spent a lot of time trying to pull from other examples, and reading through the Docs from the HTTPSecurity class, and its related classes, but I cannot understand how this configuration can be achieved.
Any help would be greatly appreciated!
Due to the nature of the project, I've had to follow a protocol which involves a slightly reduced version of oauth2. Unfortunately that has meant implementing a lot of what is already supplied in Spring Security (i.e. I'm not able to use Spring-Security-oauth2 or Spring Security 5). to fit my specific needs. I'd really appreciate any advice you would have.
I found a solution from a tutorial that involved implementing my own version of the entire authorisation process. But it works!
My SecurityConfig.java class became:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private final AuthenticationSuccessHandler loginSuccessfulHandler;
private final AuthenticationFailureHandler loginFailureHandler;
private final AccessDeniedHandler customAccessDeniedHandler;
private final AuthenticationEntryPoint customAuthenticationEntryPoint;
@Autowired
public SecurityConfig(AuthenticationSuccessHandler loginSuccessfulHandler, AuthenticationFailureHandler loginFailureHandler, AccessDeniedHandler customAccessDeniedHandler, AuthenticationEntryPoint customAuthenticationEntryPoint) {
this.loginSuccessfulHandler = loginSuccessfulHandler;
this.loginFailureHandler = loginFailureHandler;
this.customAccessDeniedHandler = customAccessDeniedHandler;
this.customAuthenticationEntryPoint = customAuthenticationEntryPoint;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user").password("password").roles("USER")
.and()
.withUser("admin").password("password").roles("ADMIN");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable() // disable CSRF for this application
.formLogin() // Using form based login instead of Basic Authentication
.loginProcessingUrl("/oauth/token") // Endpoint which will process the authentication request. This is where we will post our credentials to authenticate
.successHandler(loginSuccessfulHandler)
.failureHandler(loginFailureHandler)
.and()
.authorizeRequests()
.antMatchers("/oauth/token").permitAll() // Enabling URL to be accessed by all users (even un-authenticated)
.antMatchers("/swagger-ui.html").permitAll()
//.antMatchers("/secure/admin").access("hasRole('ADMIN')") // Configures specified URL to be accessed with user having role as ADMIN
.anyRequest().authenticated() // Any resources not mentioned above needs to be authenticated
.and()
.exceptionHandling().accessDeniedHandler(customAccessDeniedHandler)
.authenticationEntryPoint(customAuthenticationEntryPoint)
.and()
.anonymous().disable(); // Disables anonymous authentication with anonymous role.
}
And so I had to implement my login(success/failure)handler etc, by impleneting the existing interface. Now I just need to implement my own AuthenticationMangager instead of the in-memory config currently being used.
@dur thanks for helping! :)
