          書接上回,
          上回說到,武松武二郎斗殺西門慶,為大哥報(bào)了仇……? !!!-_- 啊,說串了,嘿嘿 不好意思
          (刪掉上面一行)
          上回說到,我們的設(shè)置頁面已經(jīng)做好了,接下來就是將時(shí)間轉(zhuǎn)換為Unix Cron Expression。

          2) 將時(shí)間轉(zhuǎn)換為Unix Cron Expression

          需要ActionForm將頁面表單數(shù)據(jù)映射到Action中,然后在Action中轉(zhuǎn)換為cron expression:

          ?1 SchedulerForm?schedulerForm? = ?(SchedulerForm)?form;
          ?2 ????????String?jobName? = ?schedulerForm.getJobName();
          ?3 ????????String?cronExpression? = ? "" ;
          ?4 ????????String[]?commonNeeds? = ? {schedulerForm.getSecond(),?schedulerForm.getMinute(),?schedulerForm.getHour()} ;
          ?5 ????????String[]?monthlyNeeds? = ? {schedulerForm.getWeek(),?schedulerForm.getDayOfMonth()} ;
          ?6 ????????String?weeklyNeeds? = ?schedulerForm.getDayOfWeek();
          ?7 ????????String?userDefinedNeeds? = ?schedulerForm.getDate();
          ?8 ????????String?everyWhat? = ?schedulerForm.getEveryWhat();
          ?9 ???????? // 得到時(shí)間規(guī)則
          10 ????????cronExpression? = ?CronExpConversion.getCronExpression(everyWhat,?commonNeeds,
          11 ????????????????monthlyNeeds,?weeklyNeeds,?userDefinedNeeds);
          12

          我定義了一個(gè) 規(guī)則類來處理轉(zhuǎn)換規(guī)則(寫得不是很好 能用就行 嘿嘿)
          ?1
          ?2 /**

          ?6 public ? class ?CronExpConversion? {
          ?7 ????
          ?8 ???? /**

          17 ???? public ? static ?String?convertDateToCronExp(String?everyWhat,
          18 ????????????String[]?commonNeeds,?String[]?monthlyNeeds,?String?weeklyNeeds,

          ? else ? if ?( " userDefined " .equals(everyWhat))? {
          43 ????????????String?dayOfMonth? = ?userDefinedNeeds.split( " - " )[ 2 ];
          44 ???????????? if ?(dayOfMonth.startsWith( " 0 " ))? {
          45 ????????????????dayOfMonth? = ?dayOfMonth.replaceFirst( " 0 " ,? "" );
          46 ????????????}

          47 ????????????String?month? = ?userDefinedNeeds.split( " - " )[ 1 ];
          48 ???????????? if ?(month.startsWith( " 0 " ))? {
          49 ????????????????month? = ?month.replaceFirst( " 0 " ,? "" );
          50 ????????????}

          51 ????????????String?year? = ?userDefinedNeeds.split( " - " )[ 0 ];
          52 ???????????? // FIXME?暫時(shí)不加年份?Quartz報(bào)錯(cuò)
          53 ???????????? /* cronEx?=?(commons?+?dayOfMonth?+?"?"?+?month?+?"?"
          54 ????????????????????+?CronExRelated.specialCharacters.get(CronExRelated._ANY)

          56 ????????????cronEx? = ?(commons? + ?dayOfMonth? + ? " ? " ? + ?month? + ? " ? "
          57 ???????????????????? + ?CronExRelated.specialCharacters.get(CronExRelated._ANY)

          59 ????????}

          60 ???????? return ?cronEx;
          61 ????}
          ????
          62 }

          63
          這樣就將頁面的時(shí)間設(shè)置轉(zhuǎn)為了Cron Expression。

          ?????????? ??????????????????????????????????????? To Be Continued...
