具有审慎标志和文件位置的Logback RollingFileAppender的设置

问题描述

我怎样才能在Logback中创建一个RollingFileAppender来接受审慎的标志，并允许我指定日志文件的位置?

How can I craete a RollingFileAppender in Logback that accepts the prudent flag and also allows me to specifity the location of the log files?

我尝试了以下操作，但是据我了解，从文档登录中不支持file属性.还有另一种设置日志文件位置的方法吗?

I tried the following but as I understand from the documentation logback doesn't support the file property. Is there another way to set the log file location?

   <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${MY_LOG_LOCATION_PROP}/logs/mylogfile.log</file>
        <prudent>true</prudent>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily -->
            <fileNamePattern>mylogfile-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        </rollingPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

推荐答案

如果缺少file属性，将从fileNamePattern的值推断出当前活动的日志文件.因此，file属性不是必需的.同样重要的是，在审慎模式下，必须留空.

If the file property is missing, the currently active log file will be inferred from the value of fileNamePattern. Thus, the file property is not mandatory. Just as importantly, in prudent mode it must be left blank.

以下是 fileNamePattern
