例外情况是，未定义编码器。尝试类似
<appender name="ROLLIN" > <file>logFile.log</file> <rollingPolicy > <!-- daily rollover --> <fileNamePattern>logFile.%d{yyyy-MM-dd}.log</fileNamePattern> <!-- keep 30 days' worth of history capped at 3GB total size --> <maxHistory>30</maxHistory> <totalSizeCap>3GB</totalSizeCap> </rollingPolicy> <enprer> <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> </enprer> </appender>有关更多详细信息，请参见官方文档
