How to apply spring security filter only on secured endpoints?

Question

I have the following Spring Security configuration:

httpSecurity         .csrf().disable()         .exceptionHandling()             .authenticationEntryPoint(unauthorizedHandler)             .and()         .sessionManagement()             .sessionCreationPolicy(SessionCreationPolicy.STATELESS)             .and()         .authorizeRequests()             .antMatchers("/api/**").fullyAuthenticated()             .and()         .addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class); 

The authenticationTokenFilterBean() is applied even on endpoints that do not match /api/** expression. I also tried adding the following configuration code:

@Override public void configure(WebSecurity webSecurity) {     webSecurity.ignoring().antMatchers("/some_endpoint"); } 

but this still did not solve my problem. How can I tell Spring Security to apply filters only on endpoints that match the secured URI expression?

Answer 1

I have an application with the same requirement and to solve it I basically restricted Spring Security to a given ant match patter (using antMatcher) as follows:

http     .antMatcher("/api/**")     .authorizeRequests() //         .anyRequest().authenticated() //         .and()     .addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class); 

You can read it as follows: for http only invoke these configurations on requests matching the ant pattern /api/** authorizing any request to authenticated users and add filter authenticationTokenFilterBean() before UsernamePasswordAuthenticationFilter. For all others requests this configuration has no effect.
