spring cloud gateway 413Request Entity Too Large

spring cloud gateway

413Request Entity Too Large

Get請求，參數很長，但是直接請求服務正常，從gateway請求就會報錯

排除nginx的原因

解決方案：

@Component
public class NettyConfiguration implements WebServerFactoryCustomizer<NettyReactiveWebServerFactory> {

    @Value("${server.max-initial-line-length:10485760}")
    private int maxInitialLingLength;

    @Override
    public void customize(NettyReactiveWebServerFactory container) {
        container.addServerCustomizers(
                httpServer -> httpServer.httpRequestDecoder(
                        httpRequestDecoderSpec -> httpRequestDecoderSpec.maxInitialLineLength(maxInitialLingLength)
                )
        );
    }

}
