Hibernate及Spring quartz開發中幾個注意點

由Hibernate取得的多字段List類型按一下方法讀出：

            List countStatus=asDao.getCountOfStatus();

            Iterator it = countStatus.iterator();           

            while (it.hasNext()) {
                Object[] cStatus = (Object[]) it.next();
                System.out.println(cStatus[0].toString());

                ....
            }

 

Spring中用到quartz插件配置的含義如下：

Field Name	Mandatory	Allowed Values	Allowed Special Characters
Seconds	YES	0-59	, - * /
Minutes	YES	0-59	, - * /
Hours	YES	0-23	, - * /
Day of month	YES	1-31	, - * ? / L W
Month	YES	1-12 or JAN-DEC	, - * /
Day of week	YES	1-7 or SUN-SAT	, - * ? / L #
Year	NO	empty, 1970-2099	, - * /

 

參數可以由六個參數或其各參數組成，其中對?和*的解釋如下：

 

• * ("all values" ) - used to select all values within a field. For example, "*" in the minute field means "every minute" .
• * 所有值，用來選擇這個字段內的所有值，例如，在分鐘內的*表示每一分鐘。

• ? ("no specific value" ) - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but don't care what day of the week that happens to be, I would put "10" in the day-of-month field, and "?" in the day-of-week field. See the examples below for clarification.
• ? 沒有具體的值，用來在你需要確定兩個字段值中的一個時。例如，如果我想觸發一個月中的特定一天(10日), 但是不論是一個星期中的哪一天，我就會在day-of-month字段放上10，在day-of-week字段放上問號。（簡而言之，*和?用來解決day-of-week和day-of-month在設定上的衝突，這兩個字段不能同時出現*）
