在Spring 5 Webflux中启用CORS？

我使用此自定义过滤器成功：

import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.http.HttpHeaders;import org.springframework.http.HttpMethod;import org.springframework.http.HttpStatus;import org.springframework.http.server.reactive.ServerHttpRequest;import org.springframework.http.server.reactive.ServerHttpResponse;import org.springframework.web.cors.reactive.CorsUtils;import org.springframework.web.server.ServerWebExchange;import org.springframework.web.server.WebFilter;import org.springframework.web.server.WebFilterChain;import reactor.core.publisher.Mono;@Configurationpublic class CorsConfiguration {  private static final String ALLOWED_HEADERS = "x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN";  private static final String ALLOWED_METHODS = "GET, PUT, POST, DELETE, OPTIONS";  private static final String ALLOWED_ORIGIN = "*";  private static final String MAX_AGE = "3600";  @Bean  public WebFilter corsFilter() {    return (ServerWebExchange ctx, WebFilterChain chain) -> {      ServerHttpRequest request = ctx.getRequest();      if (CorsUtils.isCorsRequest(request)) {        ServerHttpResponse response = ctx.getResponse();        HttpHeaders headers = response.getHeaders();        headers.add("Access-Control-Allow-Origin", ALLOWED_ORIGIN);        headers.add("Access-Control-Allow-Methods", ALLOWED_METHODS);        headers.add("Access-Control-Max-Age", MAX_AGE);        headers.add("Access-Control-Allow-Headers",ALLOWED_HEADERS);        if (request.getMethod() == HttpMethod.OPTIONS) {          response.setStatusCode(HttpStatus.OK);          return Mono.empty();        }      }      return chain.filter(ctx);    };  }}
