title: Spring security always returns HTTP 403
body: <p>I have configured a custom <code>Filter</code> that grants a spring authority for every URL other than <code>/login</code> :</p>
  
  <pre><code>public class TokenFilter implements Filter {
       @Override
       public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
            GrantedAuthority authority = new SimpleGrantedAuthority("myAuthority");
            UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken(user, token, Arrays.asList(authority));
            SecurityContextHolder.getContext().setAuthentication(auth);
        }
  }
  </code></pre>
  
  <p>and a spring configuration that protects all requests (but /<code>login</code>) with that authority :</p>
  
  <pre><code>@Configuration
  @EnableWebSecurity
  public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
      @Override
      protected void configure(HttpSecurity http) throws Exception {
          http
                  .csrf().disable()
                  .authorizeRequests()
                  .antMatchers("/login").permitAll()
                  .anyRequest().hasAuthority("myAuthority");
      }
  
  }
  </code></pre>
  
  <p>But every request except <code>/login</code> gets a HTTP <code>403</code> Forbidden.</p>
  
  <p>I have debugged and made sure the code from the filter is really triggered.</p>
  
  <p>What could be the problem?</p>
  
  <p>EDIT - when putting spring security logs in debug I get the following stack trace :</p>
