我可以在下面的行中使用host-name标签将<file>附加到文件名
<file>${HOME}/SpringAop-Info-${HOSTNAME}-${bySecond}.log</file>
但是当我尝试为host-name标签值附加<fileNamePattern>时，出现异常
<fileNamePattern>${DEV_HOME}/SpringAop-Info-${HOSTNAME}-%d{yyyyMMdd}.%i.log</fileNamePattern>
例外：

我也尝试了以下语句，但是仍然出现相同的错误
试验1：
<property name="host" value="${HOSTNAME}">
......
......
<fileNamePattern>${DEV_HOME}/SpringAop-Info-${host}-%d{yyyyMMdd}.%i.log</fileNamePattern>
试验2：
<property name="host" value="${HOSTNAME}">
......
......
<fileNamePattern>${DEV_HOME}/SpringAop-Info-%{host}-%d{yyyyMMdd}.%i.log</fileNamePattern>
试验3：
<contextName>${HOSTNAME}</contextName>
......
......
<fileNamePattern>${DEV_HOME}/SpringAop-Info-%{contextName}-%d{yyyyMMdd}.%i.log</fileNamePattern>
