在Nifi登录中创建自定义日志文件时出错

如何解决在Nifi登录中创建自定义日志文件时出错

我正在尝试为我在Nifi中的流程创建自定义日志文件；实现我想使用回退过滤器。

在我的logback.conf中，添加了一个名为LLAB_FILE的新附加程序，该附加程序按其内容过滤了日志消息：

<appender name="LLAB_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${org.apache.nifi.bootstrap.config.log.dir}/llab-transform.log</file>
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">      
      <evaluator>
        <expression>return message.contains("LLAB_TRANSFORM");</expression>
      </evaluator>
      <OnMismatch>DENY</OnMismatch>
      <OnMatch>ACCEPT</OnMatch>
    </filter>
    <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
        <fileNamePattern>${org.apache.nifi.bootstrap.config.log.dir}/llab-transform_%d.%i.log</fileNamePattern>
        <maxFileSize>100MB</maxFileSize>
        <maxHistory>30</maxHistory>
    </rollingPolicy>
    <immediateFlush>true</immediateFlush>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <pattern>%date~%level~%msg%n</pattern>
    </encoder>
</appender>

<root level="INFO">
    <appender-ref ref="LLAB_FILE"/>
</root>

但是，当Nifi启动时，此配置会出现以下错误：

我该如何解决？我不想处理日志引发nifi的流。

谢谢，温度

解决方法

http://logback.qos.ch/manual/filters.html#JaninoEventEvaluator

JaninoEventEvaluator需要Janino library。

请参阅设置文档的corresponding section。

实际上，任何评估者都需要附加库
