二、原因分析

从异常信息no applicable action for [charset]可以看出，是因为charset标签不可用导致，可能是logback版本的原因。

我的配置是这样的，存在charset标签：

    <!-- ALL -->
    <appender name="FILE-ALL" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--日志文件的路径及文件名-->
        <!--被写入的文件名，可以是相对目录，也可以是绝对目录，如果上级目录不存在会自动创建，没有默认值-->
        <file>${logback.path}/${application.name}-all.log</file>
        <!-- 如果 true，事件被追加到现存文件尾部。如果 false，清空现存文件.默认为 true -->
        <append>true</append>
        <!--临界值过滤器，过滤掉低于指定临界值的日志。当日志级别等于或高于临界值时，过滤器返回NEUTRAL；当日志级别低于临界值时，日志会被拒绝-->
        <!-- 此日志文件只记录INFO级别的 -->
        <!--<filter class="ch.qos.logback.classic.filter.ThresholdFilter">-->
            <!--<level>INFO</level>-->
        <!--</filter>-->
        <!--当发生滚动时，决定 RollingFileAppender 的行为-->
        <!--日志记录器的滚动策略，按日期，按大小记录,涉及文件移动和重命名-->
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <!-- 归档的日志文件的路径，例如今天是2018--21日志，当前写的日志文件路径为file节点指定，可以将此文件与file指定文件路径设置为不同路径，从而将当前日志文件或归档日志文件置不同的目录。
            而2018--21的归档日志文件在由fileNamePattern指定。%d{yyyy-MM-dd}指定日期格式，%i指定索引 -->
            <!--即file和fileNamePattern同时制定，当天日志名由file决定，前一天的文件名将自动改为fileNamePattern的值-->
            <!-- 若要加一层时间目录 <fileNamePattern>${logback.path}/%d{yyyy-MM-dd,aux}/${logback.info.filename}.%i.log</fileNamePattern>-->
            <!--<fileNamePattern>${logback.path}/${application.name}-info.%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>-->
            <fileNamePattern>${logback.path}/${application.name}-all.%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
            <!--控制被保留的归档文件的最大数量，超出数量就删除旧文件-->
            <!--日志文件保留天数 -->
            <maxHistory>${logback.max-history}</maxHistory>
            <!--指定文件的大小-->
            <maxFileSize>${logback.max-file-size}</maxFileSize>
        </rollingPolicy>
        <!--负责两件事，一是把日志信息转换成字节数组，二是把字节数组写入到输出流-->
        <!-- 日志文件的格式 -->
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
            <pattern>${logback.file-pattern}</pattern>
            <!--日志字符编码格式-->
            <charset>${logback.charset}</charset>
        </encoder>
    </appender>

三、解决方案

将logback配置中，charset标签去掉就可以了
