使用Spring WebFlux，可以使用WebFilter修改入站请求，使其有效。Kotlin中的示例：

@Component
class InvalidQValuesFilter : WebFilter {
  override fun filter(exchange: ServerWebExchange, chain: WebFilterChain): Mono<Void> {
    val acceptHeader = exchange.request.headers[HttpHeaders.ACCEPT]
    if (acceptHeader?.any { it.contains("*/*;q=2") } == true) {
      exchange.request.mutate().headers { headers ->
        headers[HttpHeaders.ACCEPT] = acceptHeader.map {
          it.replace("*/*;q=2", "*/*;q=0.1")
        }
      }
    }
    return chain.filter(exchange)
  }
}
