log4j根据需要输出到不同的文件

首先要定义不同的Appender

<appender name="ACTION" class="org.apache.log4j.DailyRollingFileAppender"> 
        <param name="File" value="D:\\DmsProject\\log\\ACTION\\action.log" />  
        <param name="Threshold" value="DEBUG" />  
        <param name="Append" value="true" />
        <param name="DatePattern" value="'.'yyyy-MM-dd'.log'" />  
        <layout class="org.apache.log4j.PatternLayout">  
            <param name="ConversionPattern" value="%d{HH:mm:ss,SSS} [%t] %5p [%C{1}:%L] - %m%n" />  
        </layout>  
    </appender>

<appender name="INTERFACE" class="org.apache.log4j.DailyRollingFileAppender">  
    	<param name="File" value="D:\\DmsProject\\log\\ACTION\\interface.log" />  
        <param name="Threshold" value="DEBUG" />  
        <param name="Append" value="true" />  
        <param name="DatePattern" value="'.'yyyy-MM-dd'.log'" />  
        <layout class="org.apache.log4j.PatternLayout">  
            <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss,SSS} [%t] %5p [%C{1}:%L] - %m%n" />  
        </layout>  
    </appender>

定义了com.infodms.ws包下的类log输出到interface.log文件中。

<logger name="com.infodms.ws" additivity="false">  
        <level value="info"/>  
        <appender-ref ref="INTERFACE" />  
    </logger>
