Maven下log4j的使用

1.添加slf4j log4j相关的依赖包

 <dependency>  
         <groupId>org.slf4j</groupId>  
         <artifactId>slf4j-api</artifactId>  
         <version>1.6.6</version>  
       </dependency>  
       
       <dependency>  
        <groupId>org.slf4j</groupId>  
        <artifactId>slf4j-log4j12</artifactId>  
        <version>1.6.6</version>  
       </dependency>  

       <dependency>  
        <groupId>log4j</groupId>  
        <artifactId>log4j</artifactId>  
        <version>1.2.16</version>  
       </dependency>

2.在src下添加log4j属性配置文件 log4j.properties

  1     log4j.rootLogger=INFO, RegularAirDetail_24h_log,RegularAirDetail_30d_log,RegularAirDetail_AQIRank_log,RegularAirDetail30dsSlice_log,RegularAirQuality_log,RegularLifeIndex_log,RegularPolForTrendWrf_log,RegularSpider_log,RegularMainpageDTO_log,RegularRealtimepageDTO_log,RegularAirdetailpageDTO_log

3.在web.xml中对log4j进行配置

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

4.在pom.xml中对log4j.properties在war包中可见

<build>        
         <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>*.properties</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

5.使用

Logger chargeLogger = LoggerFactory.getLogger("RegularAirDetail_24h_log");  
chargeLogger.info("hello world");
