如何防止在每个日志开始时logback输出其自身的状态? [英] How to prevent logback from outputting its own status at the start of every log?

问题描述

这似乎是一个粗心大意的错误，但我似乎找不到原因.使用logback/slf4j(最新版本slf4j-api-1.6.1，logback核心/经典0.9.24)进行记录.用于测试的最简单的日志配置是:

This seems like a carelessness error, but I can't seem to find the cause. Logging with logback/slf4j (most recent version slf4j-api-1.6.1, logback core/classic 0.9.24). Simplest log configuration for testing is:

<configuration>
 <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
  <layout class="ch.qos.logback.classic.PatternLayout">
   <!-- DONT USE THIS FORMATTER FOR LIVE LOGGING THE %L LINE NUMBER OUTPUTTER IS SLOW -->
   <pattern>%le %-1r [%c{1}:%L] %m%n</pattern>
  </layout>
 </appender>
 <root level="DEBUG">
  <appender-ref ref="stdout" />
 </root>
</configuration>

每个日志设置都以logback的内部状态行开始:

Every log setup starts with logback's internal status lines:

11:21:27,825 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]
11:21:27,826 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback-test.xml] at [file:.../logback-test.xml]
11:21:28,116 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set
11:21:28,124 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender]
11:21:28,129 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [stdout]
11:21:28,180 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component [layout] on top of the object stack.
11:21:28,206 |-WARN in ch.qos.logback.core.ConsoleAppender[stdout] - This appender no longer admits a layout as a sub-component, set an encoder instead.
11:21:28,206 |-WARN in ch.qos.logback.core.ConsoleAppender[stdout] - To ensure compatibility, wrapping your layout in LayoutWrappingEncoder.
11:21:28,206 |-WARN in ch.qos.logback.core.ConsoleAppender[stdout] - See also http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for details
11:21:28,207 |-INFO in ch.qos.logback.classic.joran.action.RootLoggerAction - Setting level of ROOT logger to DEBUG
11:21:28,207 |-INFO in ch.qos.logback.core.joran.action.AppenderRefAction - Attaching appender named [stdout] to Logger[ROOT]

，根据文档，logback的格式默认使用.然后，它完成读取配置文件(将其设置为输出其他格式)，并继续进行正确格式化的输出.有一个配置参数<configuration debug="false">，它不影响此设置.

which is, according to the docs, the format logback uses for default. It then finishes reading the config (which is set up to output a different format) and continues with the properly formatted output. There's a config parameter <configuration debug="false"> which does not affect this.

有人知道如何关闭此功能吗?

Anyone know how to shut this off?

推荐答案

如果将configuration元素的debug属性设置为true，则会将所有状态信息发送到控制台.如果这是您的问题，只需将其设置为false或将其删除.

If you set the debug attribute of the configuration element to true, you will get all status information to the console. If this is your problem, just set it to false or remove it.

如果您遇到任何级别为WARN或更高的配置问题，您还将获得所有状态信息记录到控制台(包括级别为INFO的消息).解决此问题的最佳方法是解决此问题(在您的情况下，将<layout>元素替换为<encoder>元素).

If you have any configuration problems of level WARN or above, you will also get all status information logged to the console (including messages of level INFO). The best solution to this problem is to fix the problem (in your case replace the <layout> element with an <encoder> element).

如果由于某种原因无法解决问题，但是想要从控制台中删除状态信息，则可以配置备用StatusListener.使用NopStatusListener完全删除状态信息:

If you for some reason cannot fix the problem, but want to remove the status-information from the console, you can instead configure an alternative StatusListener. Use the NopStatusListener to completely remove the status-information:

<configuration>
  <statusListener class="ch.qos.logback.core.status.NopStatusListener" />
  <!-- etc -->
</configuration>
