Then you need a time based appender e.g

  <appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender">
      <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
      <param name="File" value="${jboss.server.log.dir}/server.log"/>
      <param name="Append" value="true"/>
      <!-- In AS 5.0.x the server log threshold was set by a system
           property. In 5.1 and later we are instead using the system
           property to set the priority on the root logger (see <root/> below)
      <param name="Threshold" value="${jboss.server.log.threshold}"/>
      -->
      
      <!-- Rollover at midnight each day -->
      <param name="DatePattern" value="'.'yyyy-MM-dd"/>

      <!-- Rollover at the top of each hour
      <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
      -->

      <layout class="org.apache.log4j.PatternLayout">
         <!-- The default pattern: Date Priority [Category] (Thread) Message\n -->
         <param name="ConversionPattern" value="%d %-5p [%c] (%t) %m%n"/>

         <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
         <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
          -->
      </layout>
   </appender>

Read the log4j documentation for details.

#formater
log4j.appender.DFA=org.apache.log4j.DailyRollingFi leAppender
log4j.appender.DFA.File=./sample23.log
log4j.appender.DFA.DatePattern = '.'yyyy-MM-dd-HH-mm-SS
log4j.appender.DFA.layout=org.apache.log4j.Pattern Layout
#log4j.appender.DFA.layout.ConversionPattern= %d%-4r [%t] %-5p %c %x - %m%n
log4j.appender.DFA.layout.ConversionPattern= %d %-5p [%c] (%t) %m%n
