Jetty print all request log with Logback

一。准备Logback包放入$JETTY_HOME/lib/ext中

-rw-r--r-- 1 conversant conversant   93525 Apr  2  2014 logback-access-1.1.2.jar
-rw-r--r-- 1 conversant conversant  270747 Apr  2  2014 logback-classic-1.1.2.jar
-rw-r--r-- 1 conversant conversant  427729 Apr  2  2014 logback-core-1.1.2.jar

二。配置logback-access.xml并保存

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


  <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>${log.home}/requests/%d{yyyy-MM-dd}_request.log</fileNamePattern>
    </rollingPolicy>

    <encoder>
      <pattern>combined</pattern>
    </encoder>
  </appender>
 
  <appender name="all_requests" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <encoder>      
      <pattern> [%t] -%fullRequest - %fullResponse</pattern>
    </encoder>
     <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log.home}/requests/%d{yyyy-MM-dd}_all.log
            </fileNamePattern>
        </rollingPolicy>
  </appender>
        
  <appender-ref ref="all_requests"/>
   <appender-ref ref="FILE"/>
</configuration>

三。加载使用logback-access.xml

例如：jetty-requestlog-logback.xml,其具体内容如下：

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

<!-- =============================================================== -->
<!-- Configure the Jetty Request Log                                 -->
<!-- =============================================================== -->
<Configure id="Server" class="org.eclipse.jetty.server.Server">

  <!-- =========================================================== -->
  <!-- Configure Request Log -->
  <!-- =========================================================== -->
  <Ref refid="Handlers">
    <Call name="addHandler">
      <Arg>
        <New id="RequestLog" class="org.eclipse.jetty.server.handler.RequestLogHandler">
          <Set name="requestLog">
              <New id="requestLogImpl" class="ch.qos.logback.access.jetty.RequestLogImpl">
               <Set name="fileName">/opt/app/xxxx/server/conf/logback-access.xml</Set>
            </New>
          </Set>
        </New>
      </Arg>
    </Call>
  </Ref>

</Configure>

四。配置TeeFilter,打印 all_requests

路径：webapp/web.xml,增加如下代码

<filter>
        <filter-name>TeeFilter</filter-name>
        <filter-class>ch.qos.logback.access.servlet.TeeFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>TeeFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

五。设置启动脚本

修改JETTY_ARGS 参数加载jetty-requestlog-logback.xml文件

JETTY_ARGS="lib=$JETTY_HOME/lib $APP_HOME/conf/jetty/jetty.xml $APP_HOME/conf/jetty/jetty-requestlog-logback.xml OPTIONS=jsp"

六。重启并查看全部日志

cd ${log.home}/requests 查看 ${yyyy-MM-dd}_all.log 文件，即可看到输出的全部日志

总结

该配置对于需要回去http所有请求时合适。但是对于线上的生产环境由于效率以及存储空间问题，则需要关闭此配置
