How Spring security is set to avoid blocking static resources

Issue: Inherit Filtersecurityinterceptor Custom Spring Security Interceptor, but how do I set up a static resource such as CSS each time it is blocked?

@Overrideprotected void Configure (Httpsecurity http) throws exception{    http              . authorizerequests ()              . Anyrequest (). authenticated (). and              ()              //login address, successful jump address, Login failed address              . Formlogin (). LoginPage ("/login")              . Defaultsuccessurl ("/", True)              . Failureurl ("/login?error")              //grant access to all users above addresses              . Permitall ();     Settings can be IFRAME access to    http.headers (). Frameoptions (). Sameorigin ();    }
