Access_log 输出内容自定义解决方案

背景：最近项目组对网关服务依赖的框架由zuul调整到Gateway.由于升级之后的网关服务没办法打成war包部署到tomcat。导致前期依赖tomcat的生成的access_log方案要调整。通过查询Gateway官网提供的生成access_log与我们之前相比缺了不少内容。能否实现Gateway生成的access_log内容定制化成了解决问题的关键。 解决方案：这里就不卖关子了。不过大家在阅读文章时候，建议去官网了解下。

import org.springframework.boot.web.embedded.netty.NettyServerCustomizer; import org.springframework.stereotype.Component; import reactor.netty.http.server.HttpServer; import reactor.netty.http.server.logging.AccessLog; import reactor.netty.http.server.logging.AccessLogFactory; import reactor.util.annotation.Nullable;

import java.net.InetSocketAddress; import java.net.SocketAddress; import java.time.format.DateTimeFormatter;

@Component public class AccessLogNettyServerCustomizer implements NettyServerCustomizer { static final String DEFAULT_LOG_FORMAT = ""{}" {} {} [{}] "{} {} {}" {} {} "{}" "{}" "{}" {} {} "{}" "{}" "{}" "{}" "; static final String MISSING = "-";

static final DateTimeFormatter DATE_TIME_FORMATTER =
        DateTimeFormatter.ofPattern("dd/MMM/yyyy:HH:mm:ss Z");

@Override
public HttpServer apply(HttpServer httpServer) {
    httpServer = httpServer.accessLog(true, AccessLogFactory.createFilter(
            accessLogArgProvider -> true, accessLogArgProvider -> AccessLog.create(DEFAULT_LOG_FORMAT, applyAddress(accessLogArgProvider.remoteAddress()),MISSING, accessLogArgProvider.user()
                    ,accessLogArgProvider.accessDateTime().format(DATE_TIME_FORMATTER), accessLogArgProvider.method(), accessLogArgProvider.uri(), accessLogArgProvider.protocol()
                    ,accessLogArgProvider.status(),accessLogArgProvider.contentLength() > -1 ? accessLogArgProvider.contentLength() : MISSING
                    ,accessLogArgProvider.responseHeader("Referer") == null ? MISSING : accessLogArgProvider.responseHeader("Referer")
                    ,accessLogArgProvider.responseHeader("trackingID") == null ? MISSING : accessLogArgProvider.responseHeader("trackingID")
                    ,accessLogArgProvider.requestHeader("User-Agent") == null ? MISSING : accessLogArgProvider.requestHeader("User-Agent")
                    ,accessLogArgProvider.requestHeader("Host") == null ? MISSING : accessLogArgProvider.requestHeader("Host")))
    );
    return httpServer;
}

static String applyAddress(@Nullable SocketAddress socketAddress) {
    return socketAddress instanceof InetSocketAddress ? ((InetSocketAddress) socketAddress).getHostString() : MISSING;
}

}

代码里的LOG_FORMAT请结合实际情况调整。 参考文章：www.helloworld.net/special/xtm…
