我找到了方法，希望对您有所帮助：
@Beanpublic WebFilter httpsRedirectFilter() { return new WebFilter() { @Override public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) { URI originalUri = exchange.getRequest().getURI(); //here set your condition to http->https redirect List<String> forwardedValues = exchange.getRequest().getHeaders().get("x-forwarded-proto"); if (forwardedValues != null && forwardedValues.contains("http")) { try { URI mutatedUri = new URI("https", originalUri.getUserInfo(), originalUri.getHost(), originalUri.getPort(), originalUri.getPath(), originalUri.getQuery(), originalUri.getFragment()); ServerHttpResponse response = exchange.getResponse(); response.setStatusCode(HttpStatus.MOVED_PERMANENTLY); response.getHeaders().setLocation(mutatedUri); return Mono.empty(); } catch (URISyntaxException e) { throw new IllegalStateException(e.getMessage(), e); } } return chain.filter(exchange); } };}
