I have the same problem. Are there any solution without spring security? Same version 2.9.2

I solved this by Spring security (this code is in kotlin but doesnt matter). Perhaps it might help you

Eventually I solved this by spring security, as @UsamaAmjad proposed. 

    open class SecurityInitializer : AbstractSecurityWebApplicationInitializer()

    @Configuration
    @EnableWebSecurity
    open class SecurityConfig : WebSecurityConfigurerAdapter() {
    
    
        @Throws(Exception::class)
        override fun configure(http: HttpSecurity) {
            http.antMatcher("/docs/swagger/v2/api-docs").addFilter(myFilter())
        }
    
        open fun myFilter() = object : FilterSecurityInterceptor() {
            override fun doFilter(request: ServletRequest?, response: ServletResponse?, chain: FilterChain?) {
                
                if (do your stuff here) {
                    chain!!.doFilter(request,response) // continue with other filters
                } else {
                    super.doFilter(request, response, chain) // filter this request
                }
            }
        }
    }
