tomcat上的Logback配置

我在Tomcat（7.0.37）上使用Logback。我想配置logback，在其中它可以为我写网络可访问的日志文件，但我甚至可以配置它在控制台上写入。我无法在控制台上格式化日志消息。它总是以默认格式和异常返回给我。tomcat上的Logback配置

%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n

这里是我的logback-access.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<configuration debug="true"> 
    <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener" /> 

    <appender name="RootFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender"> 
     <file>testing</file> 
     <append>true</append> 

     <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> 
      <fileNamePattern>testing.%i</fileNamePattern> 
      <minIndex>1</minIndex> 
      <maxIndex>12</maxIndex> 
     </rollingPolicy> 

     <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> 
      <maxFileSize>1MB</maxFileSize> 
     </triggeringPolicy> 

     <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"> 
      <layout class="ch.qos.logback.classic.html.HTMLLayout"> 
       <pattern>%d{yyyy-MM-dd HH:mm:ss} %m%n</pattern> 
      </layout> 
     </encoder> 
    </appender> 

    <appender name="RootConsoleAppender" class="ch.qos.logback.core.ConsoleAppender"> 
     <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> 
      <pattern>%d{yyyy-MM-dd HH:mm:ss} %-6level- %logger{36}: %msg%n</pattern> 
     </encoder> 
    </appender> 

    <appender-ref ref="RootFileAppender"/> 
    <appender-ref ref="RootConsoleAppender"/> 
</configuration>

有了这个配置，我得到每当有一次例外HTTP请求到我的服务器如下：

18:08:19,951 |-ERROR in ch.qos.logback.core.ConsoleAppender[RootConsoleAppender] - Appender [RootConsoleAppender] failed to append. java.lang.ClassCastException: ch.qos.logback.access.spi.AccessEvent cannot be cast to ch.qos.logback.classic.spi.ILoggingEvent

Logback-Access用于访问日志。 Logback-access与logback-classic有不同的意图。因此，在logback-access配置文件中，您需要使用“ch.qos.logback。access”包中的PatternLayoutEncoder而不是“ch.qos.logback。classic .encoder”包。

例如，写：

<appender name="RootConsoleAppender" class="ch.qos.logback.core.ConsoleAppender"> 
    <encoder class="ch.qos.logback.access.PatternLayoutEncoder"> 
    <pattern>%clientHost %l %user %date "%r" %statusCode %bytesSent</pattern> 
    </encoder> 
</appender>

请同时参阅列出可用于logback-access PatternLayout转换字。

更好的是，不要设置'class'属性。它适用于''。 – 2015-08-19 13:26:26

我发现这个话题在寻找一个例外

ch.qos.logback.classic.AsyncAppender - Appender failed to append. java.lang.ClassCastException: ch.qos.logback.access.spi.AccessEvent cannot be cast to ch.qos.logback.classic.spi.ILoggingEvent

的解决方案，这似乎是长期已知的问题，这里报告：https://github.com/qos-ch/logback/pull/185

长话短说

AsyncAppender不适用于AccessEvent这是默认访问日志为tomcat。
