1、获取服务器名称/ip/pid/端口方法详见：//www.greatytc.com/p/346f9f50ac88
2、创建一个类继承自ch.qos.logback.classic.pattern.ClassicConverter，重写方法：
@Override
public String convert(ILoggingEvent event) {}
3、在logback-spring.xml文件里加入配置获取ip类
<conversionRule conversionWord="ip" converterClass="com.xxx.xxx.xxx.common.LogIpConfig" />
4、具体使用：
"host": "%ip" 这样写，本地日志输入的时候内容是： "host": "127.0.0.1"
