<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
