如何在Logback日志配置里获取服务器Ip和端口

1、新建一个类继承ClassicConverter,在方法中获取服务器ip

package com.xxx.xxx.xxx.common;

import ch.qos.logback.classic.pattern.ClassicConverter;
import ch.qos.logback.classic.spi.ILoggingEvent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.net.InetAddress;
import java.net.UnknownHostException;

/**

public class LogIpConfig extends ClassicConverter {
 private static final Logger logger = LoggerFactory.getLogger(LogIpConfig .class);
    private static String webIP;
    static {
        try {
            webIP = InetAddress.getLocalHost().getHostAddress();
        } catch (UnknownHostException e) {
            logger.error("获取日志Ip异常", e);
            webIP = null;
        }
    }

    @Override
    public String convert(ILoggingEvent event) {
        return webIP;
    }
}

2、在配置文件logback.xml增加如下配置:

<conversionRule conversionWord="ip" converterClass="com.xxx.xxx.xxx.common.LogIpConfig" />

3、在需要用到ip的位置这样写: %ip

"host": "%ip" 这样写,本地日志输入的时候内容是: "host": "127.0.0.1"

4、获取端口号,同理:

package com.xxx.xxx.xxx.common;

import ch.qos.logback.classic.pattern.ClassicConverter;
import ch.qos.logback.classic.spi.ILoggingEvent;
import org.apache.commons.lang3.ObjectUtils;
import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.management.MBeanServer;
import javax.management.MBeanServerFactory;
import javax.management.ObjectName;
import java.util.HashSet;
import java.util.Iterator;
import java.util.List;
import java.util.Set;

/**

public class LogPortConfig extends ClassicConverter {
    private static final Logger logger = LoggerFactory.getLogger(LogPortConfig.class);
    private static String webPort;

    static {
        try {
            List<MBeanServer> serverList = MBeanServerFactory.findMBeanServer(null);
            for (MBeanServer server : serverList) {
                Set<ObjectName> names = new HashSet<ObjectName>();
                names.addAll(server.queryNames(new ObjectName("Catalina:type=Connector,*"), null));
                Iterator<ObjectName> it = names.iterator();
                while (it.hasNext()) {
                    ObjectName oName = (ObjectName) it.next();
                    String pValue = (String) server.getAttribute(oName, "protocol");
                    if (StringUtils.equals("HTTP/1.1", pValue)) {
                        webPort = ObjectUtils.toString(server.getAttribute(oName, "port"));
                    }
                }
            }
        } catch (Exception e) {
            logger.error("获取port失败,影响logback的文件拼接", e);
            webPort = null;
        }
    }

    @Override
    public String convert(ILoggingEvent event) {
        return webPort;
    }
}
<conversionRule conversionWord="port" converterClass="com.xxx.xxx.xxx.common.LogPortConfig" />
%ip:%port
