推荐答案

我使用此自定义过滤器取得了成功：

I had success with this custom filter:

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; @Configuration public 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); }; } }

和 org.springframework.boot：spring-boot-starter-web 不应包含在依赖项中 - 过滤器不能用于它。

and org.springframework.boot:spring-boot-starter-web should not be included as dependency - filter does not work with it.
