Log4j配置指南

1、在工程中引入log4j-1.2.12.jar和commons-logging.jar.
commons-logging.jar的版本为1.0.3,低版本的配置稍有不同

2、在WEB-INF\classes目录下新建commons-logging.properties文件,文件内容如下:

org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger

此行将log实现指定为Log4j
3、在WEB-INF\classes目录下新建log4j.properties文件,简单的配置文件示例如下:

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


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


注意一:在上述实现类中也可以选用Log4JCategoryLog,但是会出现一些异常:FAIL -
Encountered exception
java.lang.NoSuchMethodError:org.apache.log4j.Category.log(****)


原因:commons-logger.jar和你的log4j.jar版本不兼容。前者是对后者的一个封装,而hibernate中主要是使用前者。前者的功能就是:它封装了一些通常的日志类,比如log4j,java.util.logging.Logger
等,使用的log4j,但是由于版本不对,commons-logger中用了log4j中的那个类,在当前的log4j版本中已经不存在了,所以报错


解决方法:将class目录下commons-logging.properties
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JCategoryLog
更改为
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger



注意二:在配置过程中我log4j.properties放于WEB-INF目录下,并修改相应的log4jConfigLocation,结果没有成功,不过用上述的配置没有问题



注意三:在配置输出路径时由于粗心写成如下:


log4j.appender.file.File=D:\log.log


没有看到任何结果,后来发现路径写错拉,这点要注意啊,呵呵


log4j.appender.file.File=D:/log.log


网友例一:功能比较多

LOG4J的配置之简单使它遍及于越来越多的应用中了:Log4J配置文件实现了输出到控制台、文件、回滚文件、发送日志邮件、输出到数据库日志表、自定义标签等全套功能。择其一二使用就够用了,

web.xml中的修改:


这样配置文件以及日志文件可以在spring的帮助下,放到开发环境中的任意位置


在这里定位配置文件,需要的是从root开始的绝对路径

,或者设置个


 

<context-param>

<param-name>log4jConfigLocation</param-name>

<param-value>classpath:log4j.properties</param-value>

</context-param>


<!--Spring默认刷新Log4j配置文件的间隔,单位为millisecond-->

<context-param>

<param-name>log4jRefreshInterval</param-name>

<param-value>60000</param-value>

</context-param>


<!--Springlog4jConfigloader-->

<listener>

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

</listener>

设置监听器

 

<context-param>

<param-name>log4jConfigLocation</param-name>

<param-value>classpath:log4j.properties</param-value>

</context-param>

<servlet>

<servlet-name>log4j</servlet-name>

<servlet-class>

org.springframework.web.util.Log4jConfigServlet
</servlet-class>

<load-on-startup>0</load-on-startup>

</servlet>


==================================


什么都做完了,那该测试了,


在action中增加



staticLogger_log=Logger.getLogger(this.getClass().getName);
//log4j(1)然后就可以在需要的地方进行日志记载
_log.debug("做下测试.debug");
_log.info(
"做下测试.info");
_log.warn(
"做下测试.warn");
_log.error(
"做下测试.error");
_log.fatal(
"做下测试.fatal");


 



补充:


有时候log日志的位置总觉的绝对路径不爽,那你可以用参数啊,比如${webapp.root}/WEB-INF/log/就是你的项目路径里的了,具体在哪里你自己看了
