Class PreFlightRequestWebFilter

java.lang.Object

org.springframework.web.cors.reactive.PreFlightRequestWebFilter

All Implemented Interfaces:

WebFilter

public class PreFlightRequestWebFilter
extends Object
implements WebFilter

WebFilter that handles pre-flight requests through a PreFlightRequestHandler and bypasses the rest of the chain.

A WebFlux application can simply inject PreFlightRequestHandler and use it to create an instance of this WebFilter since @EnableWebFlux declares DispatcherHandler as a bean and that is a PreFlightRequestHandler.

Since:

5.3.7
