1. 添加依赖
   
   

    1             <properties>

2. 在src/main/rescources目录下创建log4j.xml文件
   
   

    1 <?xml version="1.0" encoding="UTF-8"?>    
    2 <!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
    3 <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
    4 
    5     <!-- [控制台STDOUT] -->
    6     <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
    7         <param name="encoding" value="UTF-8" />
    8         <param name="target" value="System.out" />
    9         <layout class="org.apache.log4j.PatternLayout">
   10             <param name="ConversionPattern" value="%-5p %c{2} - %m%n" />
   11         </layout>
   12     </appender>
   13     <!-- [公共Appender] -->
   14     <appender name="DEFAULT-APPENDER" class="org.apache.log4j.DailyRollingFileAppender">
   15         <param name="File" value="${webapp.root}/logs/common-default.log" />
   16         <param name="Append" value="true" />
   17         <param name="encoding" value="UTF-8" />
   18         <param name="DatePattern" value="‘.‘yyyy-MM-dd‘.log‘" />
   19         <layout class="org.apache.log4j.PatternLayout">
   20             <param name="ConversionPattern" value="%d %-5p %c{2} - %m%n" />
   21         </layout>
   22     </appender>
   23     <!-- [错误日志APPENDER] -->
   24     <appender name="ERROR-APPENDER" class="org.apache.log4j.DailyRollingFileAppender">
   25         <param name="File" value="${webapp.root}/logs/common-error.log" />
   26         <param name="Append" value="true" />
   27         <param name="encoding" value="UTF-8" />
   28         <param name="threshold" value="error" />
   29         <param name="DatePattern" value="‘.‘yyyy-MM-dd‘.log‘" />
   30         <layout class="org.apache.log4j.PatternLayout">
   31             <param name="ConversionPattern" value="%d %-5p %c{2} - %m%n" />
   32         </layout>
   33     </appender>
   34         <!-- 由于用了springmvc框架，日志配置好后，会输出很多spring日志，在log4j.xml中，增加一段配置，修改spring包的日志输出级别 -->
   35     <!-- 通过<category></category>的定义可以将各个包中的类日志输出到不同的日志文件中 -->
   36     <category name="org.springframework">
   37         <priority value="error" />
   38         <appender-ref ref="CONSOLE" />
   39     </category>
   40     <!-- Root Logger -->
   41     <root>
   42         <level value="${rootLevel}"></level>
   43         <appender-ref ref="CONSOLE" />
   44         <appender-ref ref="DEFAULT-APPENDER" />
   45         <appender-ref ref="ERROR-APPENDER" />
   46     </root>
   47 
   48 </log4j:configuration>

3. 修改web.xml文件，添加log4j配置
   
   

    1     <!-- 配置加载log4j.xml文件路径 -->
    2     <context-param>
    3         <param-name>log4jConfigLocation</param-name>
    4         <param-value>classpath:log4j.xml</param-value>
    5     </context-param>
    6 
    7     <!-- 配置log4j.xml变量 -->
    8     <context-param>
    9         <param-name>rootLevel</param-name>
   10         <param-value>DEBUG</param-value>
   11     </context-param>
   12 
   13     <context-param>
   14         <param-name>loggingLevel</param-name>
   15         <param-value>INFO</param-value>
   16     </context-param>
   17 
   18     <listener>
   19         <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
   20     </listener>

   View Code
4. 另外在log4j.xml中添加新元素时最好按照下列顺序，
   
   

   1 <renderer></renderer>
   2 <appender></appender>
   3 <plugin></plugin>
   4 <logger></logger>
   5 <category></category>
   6 <root></root>
   7 <loggerfactory></loggerfactory>>
   8 <categoryfactory></categoryfactory>

   View Code

   我添加<category>的时候放在了<root>标签后，配置文件报错
   

5. OK , 继续撸码..............
