    <rollingpolicy name="myrollingpolicy" type="sizewin" maxsize="104857600" maxnum="10" />    

        <!--sizewin 表示达到最大值后新建日志文件  值由maxsize设定

            maxnum  最大文件数目 

         -->

 
    <appender name="myrollingfileappender" type="rollingfile" logdir="./" prefix="mylogfile" layout="dated" rollingpolicy="myrollingpolicy" />

       <!--logdir 日志输出路径

           prefix  文件名

           layout 输出格式 （与下方layout对应）

              例如dated为:

                  20110727 09:21:10.167 WARN     log4ctest- [    main.c][  57][      main()]: shit!-99947
                  20110727 09:21:10.167 WARN     log4ctest- [    main.c][  57][      main()]: shit!-99948
                  20110727 09:21:10.167 WARN     log4ctest- [    main.c][  57][      main()]: shit!-99949

              basic为:

                  WARN     log4ctest - [    main.c][  57][      main()]: shit!-99982
                  WARN     log4ctest - [    main.c][  57][      main()]: shit!-99983
                  WARN     log4ctest - [    main.c][  57][      main()]: shit!-99984
                  WARN     log4ctest - [    main.c][  57][      main()]: shit!-99985
