log4j中報錯詳解

warn: Posix file attribute permissions defined but it is not supported by this files system.

log4j2.xml有下面配置

<RollingFile name="RollingFileInfo" filePermissions="rw-r--r--"
                     fileName="/var/log/springboot/spring-boot-start0.log"
                     filePattern="/var/log/springboot/spring-boot-start0-%d{yyyy-MM-dd}-%i.log">
            <Filters>
                <ThresholdFilter level="INFO" />
            </Filters>
            <PatternLayout charset="UTF-8" pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n" />
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="100M"/>
            </Policies>
        </RollingFile>

這是由於win系統不支持“filePermissions”所致，但最終會跑在linux上，顧上面的warning可以忽略。
