有没有办法限制log4j2的jsonlayout中消息值的字符？当前的配置是这样的

<Console name="CONSOLE_APPENDER" target="SYSTEM_OUT">
        <BurstFilter level="INFO" rate="2" maxBurst="10"/>
        <JsonLayout compact="false" eventEol="false" stacktraceAsString="true">
            <KeyValuePair key="timestamp" value="$${date:yyyy-MM-dd'T'HH:mm:ss.SSSZ}" />
            <KeyValuePair key="BuildNumber" value="$${ctx:BuildNumber:-}"/>
        </JsonLayout>
    </Console>
