根据appCode存储日志

我的是根据不同的appCode，打印不同的文件夹中，如果没有拿到appCode，就打印到default中

在拦截器中，网mdc中put对应的appCode，在xml中使用${appCode}获取即可

时区动态设置

application.yml

yaml 复制代码

timezone:
  defaultTimeZone: 时区

定义属性关键代码：

xml 复制代码

<springProperty scop="context" name="timeZone" source="timezone.defaultTimeZone" defaultValue=""/>

使用取值：

xml 复制代码

${log.path}/${spring.application.name}/${appCode}/${spring.application.name}-${container.id}.%d{yyyy-MM-dd,${timeZone}}.%i.log
