如何在Logback中过滤堆栈跟踪帧

Question

假设我有两个Java类:foo.ClassA和bar.ClassB.要打印(根)异常堆栈跟踪,我需要只打印foo包的帧.我的问题是我是如何配置Logback来做到这一点的.
我知道该功能已在Logback中实现,我需要使用evaluator.但我无法理解.我尝试了这里描述的例子没有成功(毫不奇怪).

任何人都可以提供过滤堆栈跟踪帧的确切配置吗？

<configuration>
  <evaluator name="FILTER">
    <expression>¿what should I put here?</expression>
  </evaluator>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
    <encoder>
      <pattern>[%thread] %-5level - %msg%n%rEx{full, FILTER}</pattern>
    </encoder>
  </appender>

  <root level="DEBUG"> 
    <appender-ref ref="STDOUT" /> 
  </root>
</configuration>

我联系了Tomasz Nurkiewicz(问题中链接的博客的作者),他很友好地回答了我的问题.我发布了答案,以防万一:
在打印堆栈跟踪时,要从bar包中过滤行,请使用以下命令:

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
    <encoder>
      <pattern>[%thread] %-5level - %msg%n%rEx{full, bar}</pattern>
    </encoder>
  </appender>
  ...
</configuration>

我想在我的Web应用程序(Tomcat + Spring + Hibernate +等)中使用它.所以我配置的logback与以下不从打印任何堆栈跟踪线org.something包(例如org.apache,org.springframework,org.hibernate等):

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
    <encoder>
      <pattern>[%thread] %-5level - %msg%n%rEx{full, org}</pattern>
    </encoder>
  </appender>
  ...
</configuration>

谢谢Tomasz!

这可能会帮助像我这样正在编写 springboot 应用程序的人

我目前正在使用

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true" packagingData="true">
<springProperty scope="context" name="APP_NAME" source="spring.application.name"/>
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<springProfile name="!cloud">

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${APP_NAME} %green(%d{dd-MM-yyyy HH:mm:ss.SSS}) %magenta([%thread]) %highlight(%-5level) %red(%logger.%M:%L) - %magenta(%msg) %rEx{full,java.lang.reflect.Method,

                ByCGLIB
                }%n
            </pattern>
        </encoder>
    </appender>
</springProfile>
<springProfile name="cloud">
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <!-- send cloud event in one line so kibana can log it as one event -->
            <pattern>%d{dd-MM-yyyy HH:mm:ss.SSS} [%thread] %-5level %logger.%M:%L - %msg %replace(%rEx){'[\r\n]+', '\\n'}%nopex %n</pattern>
