-quartz of timed tasks

Quartz is a opensymphony open source organization in the Job scheduling field another open source project, it can be combined with Java EE and J2SE applications can also be used alone. Quartz can be used to create simple or complex day programs for running 10, hundred, and even tens of thousands of jobs. Jobs can be made into standard Java components or EJBs.

Transform the 202 line code of the Quartz Jobrunshell class to enable the scheduled task to support the full transaction of the database and the shutdown of the database connection:

Format: [SEC] [minutes] [hours] [day] [month] [week] [year]

Serial number	Description	is required	Values that are allowed to be filled in	Wildcard characters allowed
1	Seconds	Is	0-59	, - * /
2	Part	Is	0-59	, - * /
3	Hours	Is	0-23	, - * /
4	Day	Is	1-31	, - * ? /L W
5	Month	Is	1-12 or Jan-dec	, - * /
6	Week	Is	1-7 or Sun-sat	, - * ? L
7	Years	Whether	Empty or 1970-2099	, - * /

Wildcard Description:
*Represents all values. For example, setting "*" on a divided field means that every minute is triggered.
?Indicates that no value is specified. The scenario used is a value that does not need to be concerned about the current setting of this field. For example: to trigger an operation at number 10th per month, but don't care what the week is, so the field needs to be set to "?" set to 0 0 0 10 *?
-Represents an interval. For example, set "10-12" on the hour, indicating that the 10,11,12 point will be triggered.
,Indicates that multiple values are specified, such as setting "Mon,wed,fri" on the week field to indicate Monday, Wednesday, and Friday triggers
/Used to increment the trigger. If you set "5/15" above the second to indicate starting from 5 seconds, each 15 second trigger (5,20,35,50). Set the ' 1/3 ' on the month field to start with the 1th number per month, triggering once every three days.
LTo express the last meaning. On the day field setting, the last day of the month (according to the current month, if the February will also be based on whether the run year [leap]), in the weekly field of Saturday, the equivalent of "7" or "SAT." If you add a number before "L", it represents the last of the data. For example, a format such as "6L" is set on the week field, which means "last Friday of this month"
WRepresents the most recent working day from the specified date (Monday to Friday). For example, set "15W" on the day field to indicate the most recent weekday from 15th per month. If number 15th is exactly Saturday, find the most recent Friday (14th) trigger, and if 15th is weeks, find the nearest next Monday (16th) trigger. If the 15th number is exactly on the weekday (Monday to Friday), it is triggered on that day. If the specified format is "1W", it represents the most recent weekday trigger after the 1th number per month. If number 1th is Saturday, it will be triggered under number 3rd in Monday. (Note, "W" can only set a specific number, do not allow interval "-").

Small Tips

' L ' and ' W ' can be used in a combination. If "LW" is set on the day field, it will be triggered on the last weekday of this month (generally refers to payroll)

#Ordinal number (the number of weeks of the month), such as setting "6#3" on the week field for the third Saturday of the month. Note If you specify "#5" and the fifth week is not Saturday, the configuration is not triggered (used on Mother's Day and Father's Day).

Small Tips

The setting of the week field, if the English alphabet is case-insensitive, the MON is the same as the MON.

Common examples:

0 0/5 14 * *?	Every afternoon at 2 O ' 2:59 (the whole point starts, every 5 minutes triggers)
0 0/5 14,18 * *?	Every afternoon at 2 O ' 2:59 (the whole point starts, every 5 minutes triggers) Every afternoon at 18 O ' 18:59 (the whole point starts, every 5 minutes triggers)
0 0-5 14 * *?	Every afternoon at 2 O ' 2:05, each minute triggers
0 10,44 14? 3 WED	March every Wednesday afternoon 2:10 and 2:44 triggering

0 L *?	10:15 trigger on the last day of the month
0 15 10? * 6L	The last week of the month of Friday 10:15 Trigger
0 15 10? * 6L 2002-2005	From 2002 to 2005 the last week of the month of Friday 10:15 triggered
0 15 10? * 6#3	The third week of the month of Friday starts to trigger
0 0 12 1/5 *?	The first noon of the month starts every 5 days.
