My CORS config looks like: @Bean @Order(Ordered.HIGHEST_PRECEDENCE) public CorsWebFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

问题 We have some endpoints, that are secured and before to access them we're verifying that the jws is correctly. In order to do that, we've defined a SecurityContext that actually persist the Auth pojo and to manipulate it downstream into the controller.
