我有一个Spring Cloud Gateway应用程序，它充当我的数据服务的网关。我的应用程序使用SSE在UI中推送通知。当我看到网关的日志时，我的日志充满了异常，例如：

 2019-01-25 07:39:13,807 ERROR [reactor-http-nio-3] org.springframework.web.server.adapter.HttpWebHandlerAdapter : Unhandled failure: Connection reset by peer, response

我有一个错误处理程序类：

import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebExceptionHandler;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;

import java.io.IOException;

@Component
public class GlobalExceptionHandler implements WebExceptionHandler {

    @Override
    public Mono<Void> handle(ServerWebExchange exchange, Throwable exception) {
        if (exchange.getResponse().isCommitted()) {
            //for SSE connections, privents from filling up logs when connection is closed.
            if(exception instanceof IOException && (exception.getMessage().contains("An established connection was aborted") || exception.getMessage().contains("Connection closed prematurely"))){
                return exchange.getResponse().writeWith(Flux.just());
            }
        }
        return Mono.error(exception);
    }
}

，但它仍在记录错误。如何使我的网关不写日志。

在处理阶段不会发生此错误，而是在响应的实际流处理期间发生。这是一个很低的级别，WebExceptionHandler合同未涵盖。

您似乎正在使用Spring Framework 5.0.x，在此版本中，此异常记录在WARN级别as of 5.0.6 and #21229上。在Spring Framework 5.1.x，significant changes have been made to the logging experience中，这些日志现在处于TRACE级别，因此您不再应该默认看到这些日志。

同时，您可以调整ReactorHttpHandlerAdapter类的日志记录级别，并且仅考虑ERROR级别的日志。
