Logback 按类名过滤

Question

我正在尝试在 Logback 中创建一个类名过滤器，希望从某些包名中排除日志行。

这是我的 logback-spring.xml。在这个例子中，我试图从可能来自 Undertow 的 stacktrack 中排除每一行。

<configuration scan="true" scanPeriod="30 seconds" debug="true">

  <property name="DEFAULT_PATTERN"
    value="[%thread][%-5level][%d{yyyy-MM-dd HH:mm:ss.SSS}][%logger{40}] - %msg%n"/>

  <appender name="ConsoleAppender" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
      <evaluators>
        <evaluator>
          <expression>logger.equals("io.undertow")</expression>
        </evaluator>
        <OnMismatch>NEUTRAL</OnMismatch>
        <OnMatch>DENY</OnMatch>
      </evaluators>
    </filter>
    <layout class="ch.qos.logback.classic.PatternLayout">
      <Pattern>${DEFAULT_PATTERN}</Pattern>
    </layout>
  </appender>
  <root level="INFO">
    <appender-ref ref="ConsoleAppender"/>
  </root>

</configuration>

但是，当我启动 Spring Boot 应用程序时，它会自行停止。

将标志 debug=true 放入 XML 中，我收到以下消息：

16:44:37,859 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - Setting ReconfigureOnChangeTask scanning period to 30 seconds
16:44:37,867 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender]
16:44:37,867 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [ConsoleAppender]

我在那里做错了什么？如果我禁用过滤器，应用程序将正常启动。

正如错误所说，不要使用标签“评估者”

    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
            <evaluator>
              <expression>logger.equals("io.undertow")</expression>
            </evaluator>
            <OnMismatch>NEUTRAL</OnMismatch>
            <OnMatch>DENY</OnMatch>
    </filter>
