Spring Integrated log4j Log Management

Original address: http://blog.csdn.net/naruto1021/article/details/7969535

When using the spring framework, we can easily configure the log4j for log management.

Before configuring, you must first download the jar package (Log4j-1.2.11.jar)

The configuration is as follows:

1. At the top of Web. XML, add the following configuration code:

[HTML] View Plain copy print? <!--log4j configuration file load-->      <context-param>               <param-name>log4jConfigLocation</param-name>               <param-value>/web-inf/ log4j.properties</param-value>          </context-param >      <!--Start a watchdog thread scan every 1800 seconds for changes in log4j configuration files-->       <context-param>              < param-name>log4jrefreshinterval</param-name>               <param-value>1800000</param-value>          </context-param>       <!--spring log4j listener-->& NBsp;     <listener>               <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>           </listener>  

<!--log4j configuration file Load--
    <context-param>    
        <param-name>log4jconfiglocation</param-name >    
        <param-value>/WEB-INF/log4j.properties</param-value>    
    </context-param>
    <! --Start a watchdog thread scan every 1800 seconds log4j configuration file Changes-
    <context-param>    
        <param-name> log4jrefreshinterval</param-name>    
        <param-value>1800000</param-value>    
    </ Context-param> 
    <!--spring log4j listener--
    <listener>    
        <listener-class> Org.springframework.web.util.log4jconfiglistener</listener-class>    
    </listener>

2. Place the log4j.properties configuration file in the specified directory configured above

Log4j.properties configuration file:

[Plain] View Plain copy print? ######################################   #          LOG4J Configuration related Instructions    ######################################      #%p  output priority, i.e. debug, info,warn,error,fatal    #%r  Output The number of milliseconds that the log information is consumed from the application to output     the class that the #%c  output belongs to, Usually the full name of the class     #%t  output the thread name that generated the log event    the information specified in the #%m  output code     #%n  Output a carriage return line break, the Windows platform is "\ r \ n", the UNIX platform is "\ n"     #%d  the date or time of the output log point, the default format is ISO8601, you can specify the format later, such as:%d{ YYYY&NBSP;MM&NBSP;DD&NBSP;HH:MM:SS,SSS}, output similar:  2002 October 18  22:10:28,921    #%l  The location where the output log event occurs, including the class name, the thread that occurred, and the number of rows in the code.
