在logback的fileNamePattern配置%i 带来的异常

我在logback的配置文件中企图这样配置：

        <rollingPolicy
            class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--log file pathname -->
            <FileNamePattern>${LOG_HOME}/MmSpringWebApplication.%d{yyyy-MM-dd}%i.log
            </FileNamePattern>
            <!--days log files will be kept -->
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>

但是出现了以下异常：

Exception in thread "main" java.lang.IllegalStateException: Logback configuration error detected:
ERROR in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Filename pattern [d:/logs/MmSpringWebApplication.%d{yyyy-MM-dd}%i.log] contains an integer token converter, i.e. %i, INCOMPATIBLE with this configuration. Remove it.

    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1215)
    at MmSpringWebApplication.main(MmSpringWebApplication.java:16)

要修正也简单，不是仅仅添加%i就好了，需要整体替换：

        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/logbackCfg3.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <maxFileSize>1000MB</maxFileSize>
            <MaxHistory>60</MaxHistory>
        </rollingPolicy>

这样就%i就不会报有异常的，log也能正确书写：
