springmvc log4j配置

1. 添加依賴
   

    1             <properties>
    2             <spring.version>4.1.0.RELEASE</spring.version>
    3             <slf4j.version>1.7.13</slf4j.version>
    4             </properties>
    5                 <!-- log4j -->
    6         <dependency>
    7             <groupId>org.springframework</groupId>

   12                     <groupId>commons-logging</groupId>
   13                     <artifactId>commons-logging</artifactId>
   14                 </exclusion>
   15             </exclusions>

2. 在src/main/rescources目錄下建立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     <!-- [控制檯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="${webapp.root}/logs/common-default.log" />
   16         <param name="Append" value="true" />
   17         <param name="encoding" value="UTF-8" />
   18         <param name="DatePattern" value="'.'yyyy-MM-dd'.log'" />
   19         <layout class="org.apache.log4j.PatternLayout">
   20             <param name="ConversionPattern" value="%d %-5p %c{2} - %m%n" />
   21         </layout>
   22     </appender>
   23     <!-- [錯誤日誌APPENDER] -->
   24     <appender name="ERROR-APPENDER" class="org.apache.log4j.DailyRollingFileAppender">
   25         <param name="File" value="${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         <!-- 因爲用了springmvc框架，日誌配置好後，會輸出不少spring日誌，在log4j.xml中，增長一段配置，修改spring包的日誌輸出級別 -->
   35     <!-- 經過<category></category>的定義能夠將各個包中的類日誌輸出到不一樣的日誌文件中 -->
   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     <!-- 配置加載log4j.xml文件路徑 -->
    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變量 -->
    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中添加新元素時最好按照下列順序，
   

   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>的時候放在了<root>標籤後，配置文件報錯
   

5. OK , 繼續擼碼..............
