log 4 j日単位でスクロール設定

中には日スクロールのファイル名の配置が含まれていて、テストされていないので、暇があれば再測定します!
 
For example,

log4j.appender.fileout=org.apache.log4j.DailyRollingFileAppender
log4j.appender.fileout.File=./logs/programdolt.log
#log4j.appender.fileout.DatePattern='.'yyyy-MM-dd
log4j.appender.fileout.DatePattern='.'yyyy-MM-dd-HH-mm

public class DailyRollingFileAppender
extends FileAppender

 
DailyRollingFileAppender extends  FileAppender   so that the underlying file is rolled over at a user chosen frequency.
The rolling schedule is specified by the DatePattern option. This pattern should follow the  SimpleDateFormat  conventions. In particular, you must escape literal text within a pair of single quotes. A formatted version of the date pattern is used as the suffix for the rolled file name.
For example, if the File option is set to  /foo/bar.log  and the DatePattern set to  '.'yyyy-MM-dd  , on 2001-02-16 at midnight, the logging file  /foo/bar.log  will be copied to  /foo/bar.log.2001-02-16  and logging for 2001-02-17 will continue in  /foo/bar.log  until it rolls over the next day.
Is  is possible to  specify monthly, weekly, half-daily, daily, hourly, or minutely rollover schedules.
DatePattern
Rollover schedule
Example '.'yyyy-MM
Rollover at the beginning of each month
At midnight of May 31st, 2002  /foo/bar.log  will be copied to  /foo/bar.log.2002-05  . Logging for the month of June will be output to  /foo/bar.log  until it is also rolled over the next month. '.'yyyy-ww
Rollover at the first day of each week. The first day of the week depends on the locale.
Assuming the first day of the week is Sunday, on Saturday midnight, June 9th 2002, the file /foo/bar.log will be copied to /foo/bar.log.2002-23 . Logging for the 24th week of 2002 will be output to  /foo/bar.log  until it is rolled over the next week. '.'yyyy-MM-dd
Rollover at midnight each day.
At midnight, on March 8th, 2002,  /foo/bar.log  will be copied to  /foo/bar.log.2002-03-08  . Logging for the 9th day of March will be output to  /foo/bar.log  until it is rolled over the next day. '.'yyyy-MM-dd-a
Rollover at midnight and midday of each day.
At noon, on March 9th, 2002,  /foo/bar.log  will be copied to  /foo/bar.log.2002-03-09-AM  . Logging for the afternoon of the 9th will be output to  /foo/bar.log  until it is rolled over at midnight. '.'yyyy-MM-dd-HH
Rollover at the top of every hour.
At approximately 11:00.000 o'clock on March 9th, 2002,  /foo/bar.log  will be copied to /foo/bar.log.2002-03-09-10  . Logging for the 11th hour of the 9th of March will be output to /foo/bar.log  until it is rolled over at the beginning of the next hour. '.'yyyy-MM-dd-HH-mm
Rollover at the beginning of every minute.
At approximately 11:23,000, on March 9th, 2001,  /foo/bar.log  will be copied to  /foo/bar.log.2001-03-09-10-22  . Logging for the minute of 11:23 (9th of March) will be output to  /foo/bar.log  until it is rolled over the next minute.
Do not use the colon ":"character in anywhere in the DatePattern option. The text before the colon is interpeted as the protocol specificaion of a URL which is probably not what you want.
