Spring对log4j的增强

Spring对log4j的增强
原文出处及讨论: http://www.blogjava.net/calvin/archive/2005/12/31/26150.html

Spring最擅长的，就是在别家的蛋糕上再加些cream，让你J2EE without Spring的时候心痒痒。

log4j，可以有如下的cream：
1. 动态的改变记录级别和策略，不需要重启Web应用，如《Effective Enterprise Java》所说。
2. 把log文件定在 /WEB-INF/logs/ 而不需要写绝对路径。
3. 可以把log4j.properties和其他properties一起放在/WEB-INF/ ，而不是Class-Path。

在web.xml 添加

    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>WEB-INF/log4j.properties</param-value>
    </context-param>

    <context-param>
        <param-name>log4jRefreshInterval</param-name>
        <param-value>60000</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

在上文的配置里,
Log4jConfigListener会去WEB-INF/log4j.propeties 读取配置文件;
开一条watchdog线程每60秒扫描一下配置文件的变化;
并把web目录的路径压入一个叫webapp.root的系统变量。
然后，在log4j.properties 里就可以这样定义logfile位置

log4j.appender.logfile.File=${webapp.root}/WEB-INF/logs/myfuse.log

如果有多个web应用，怕webapp.root变量重复，可以在context-param里定义webAppRootKey。
