我正在尝试将日志异步打印到日志文件。所以我使用 AsyncAppender 到 RollingFileAppender。但不知何故，Logback 抛出错误未找到附加的附加程序

Logback 版本 logback-classic 1.3.0- alpha5使用

我正在创建一个 RollingFileAppender 并将其添加到 AsyncAppender。

下面是我的 logback.xml

<appender name="FILE-ROLLING" 
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${logPath}/zapp-info.log</file>

    <rollingPolicy 
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
        <fileNamePattern>${logPath}/archived/zapp.%d{yyyy-MM- 
dd}.%i.log</fileNamePattern>
        <SizeBasedTriggeringPolicy 
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>10MB</maxFileSize>
        </SizeBasedTriggeringPolicy>
        <totalSizeCap>20GB</totalSizeCap>
        <maxHistory>10</maxHistory>
    </rollingPolicy>
    <encoder 
class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>%d %-5level %t %c{0} %msg%n</Pattern>
    </encoder>
</appender>

<appender name="ASYNC-INFO" 
class="ch.qos.logback.classic.AsyncAppender">
    <discardingThreshold>0</discardingThreshold>
    <queueSize>256</queueSize>
    <appender-ref ref="FILE-ROLLING"/>
</appender>

控制台日志显示以下错误消息
