Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
The core of the invention is to provide a method, a device and a medium for task timing strategy, which improve the accuracy of task execution.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
In the current Web application, most applications have a task scheduling function, and the task scheduling automatically performs tasks at a given time interval or a given number of executions based on a given time point. The invention provides a method for realizing the timing tasks, which is different in realization methods according to different underlying languages of a server, comprises a Java-based Timer, a Scheduled Executor, a Quartz and a JCron Tab method, a standard Timer based on Windows in C# language, a server Timer and a thread Timer, and a timing task method based on PHP and Python languages.
Fig. 1 is a flowchart of a method for task timing policy according to an embodiment of the present invention, as shown in fig. 1, where the method includes:
s11: and acquiring a starting time stamp for starting the timing task and a first time stamp of the current timer, and calculating a second time stamp of the next timer according to a time interval of the timer, wherein the unit of the time interval is a second level.
In the management system, a timing task is added, the timing task is checked and configured, the task of a user is checked first, the timing task is written in a file form in the task of the user, at the moment, the starting time of the timing task is set, namely, the starting time is converted into a starting time stamp, wherein the time stamp is obtained by subtracting a time value of 1:00:00:00 of 1 month in 1970 from the current time, namely, the starting time of the timing task is subtracted by a time stamp obtained by subtracting 1:00:00 of 1 month in 1970.
After the configuration is completed, a timing task is started and is resident in the memory to return to the root directory to run, after the timing task is started, the timer is timed according to the timing strategy, the task is inquired, and finally the task is executed. The timing task comprises a starting time stamp and a time for executing the task, the time for executing the timing task is set according to the time interval of the timing task, the timing task has only one starting time stamp, the execution task and the starting timing task need to record a running time catalog in an application program bottom layer of a management system, the running time catalog is recorded in the form of a log or a cache catalog, the timing task can be executed once every 10s by adding a class method type, for example, a process is started, and the time interval of the timing task is 10s.
The timer comprises two types, one is triggered when reaching the designated time and is triggered once, and the other is triggered when being spaced by the specific time. The time interval of the present timer and the next timer is set according to the time interval of the timers, if the time interval of the timers is 1 minute, the first 1 minute timer is the moment of the present timer, the second 1 minute timer is the moment of the next timer, the time stamp of the corresponding timer is the same as the time stamp of the timing task, the value obtained by subtracting the time stamp of the present timer from the time stamp of the 1970 1 month 1 day 00:00:00 is obtained by subtracting the time stamp of the 1 minute 1 from the time stamp of the time of the present timer, the first time stamp of the corresponding timer is the time stamp of the first 1 minute, and the second time stamp of the next timer is the time stamp of the second 1 minute timer.
It will be appreciated that, in the above-mentioned time interval is of the order of seconds, if a task is added during the task starting and executing process according to the minute-order timing strategy, the interval time is 2 minutes, the time for starting the task is 12 hours and 10 minutes, the first 1 minute timer is 12 hours and 11 minutes, the second 1 minute timer is 12 hours and 12 minutes, the third 1 minute timer is 12 hours and 13 minutes, the fourth 1 minute timer is 12 hours and 14 minutes, and according to the difference between the time of the timer and the time for starting the task, we can easily see that the time difference between the 12 hours and the time of starting is a multiple of 2 minutes which satisfies the interval time, and the task is executed in the two timers. If a task is set at a second-level time interval, a minute-level timing strategy cannot be met, and in the minute-level timing strategy, as the set minimum unit is the minute level, no matter how accurate the set time interval and the timing strategy are, the target moment of executing the task can only reach the timing moment of the timer to execute the task, and the task cannot be executed in the interval of the timer, so that the task execution needs to be executed in a delayed time, the process is slow, and the user experience effect is affected.
In addition, the timing method based on the second-level timing strategy can be also suitable for the millisecond-level timing strategy, and for an actual management system, the millisecond-level task execution speed is high, but the number of tasks executed in the millisecond level is difficult to match, 1000 tasks cannot be processed in 1 millisecond, and the complexity of task execution is only increased. The task timing strategy aims at an in-process running scene, and the storage before stopping and the loading after starting are considered for restarting, so that the method does not need to consider.
S12: and judging whether the target time for executing the timing task exists in the time interval of the timer, and if so, proceeding to step S13.
Whether the target time for executing the timing task exists in the time interval of the present timer or not, the target time is the execution time of the timing task, it can be understood that the time interval of the present timer is a timing interval of a first time stamp and a second time stamp, whether the target time exists or not is judged in the interval, the present timer is the first 1 minute time, the next timer is the second 1 minute time in combination with the above example, the present invention only discusses the present time and the next timer as the time interval of one round, the second 1 minute of the present timer of the time interval of the next round, and the next timer is the third 1 minute calculation. If so, the process proceeds to step S13, and if not, the timing task is not executed, and the search and judgment are continued in the next time interval.
S13: and selecting the target time as the execution time of the timing task in the time interval of the timer.
When the target time for executing the timing task exists in the time interval of the timer, the target time is selected as the execution time of the timing task in the time interval of the timer. The target time is calculated according to a certain algorithm, the algorithm is different according to different timing strategies, and the target time is required to be set according to actual conditions.
For example, a timer with 5 seconds interval is started in the background, all tasks are detected at regular time, and the time interval of a certain task is 8 seconds, and the task is started for time t 0 Timer t of first one after task is started, which is 12:10:02 1 Time of the second timer t is 12:10:05 2 Time t of the third timer is 12:10:10 3 Time t of the fourth timer is 12:10:15 4 12:10:20, for the first timer t 1 Calculating the current timer t 1 And a task start time t 0 Corresponding to the difference in the time stamps, then calculate the next timer t 2 And a task start time t 0 The difference between 3 and 7 is found to be in the range of [3,8 ], a multiple of 8 is traversed between 3 and 7, a junctionIf not, not executing the process; time t of timer of the second 2 The traversal [8, 13) has or has not a multiple of 8, and as a result, 8 is a multiple of 8, which is executed this time. Time t of the third timer 3 The number of times 8 between the traversals [13,18 ] is found to be a number of times 8, and 16 is executed after this time the timer 16-13=3 seconds.
The example is based on one of the timing strategies alone, and in combination with the example, the distance is calculated within the time interval of this time (t 1 And t 2 ) Since the condition for the target time is not an integral multiple of the time interval of the timing task, the target time is not present and the next time interval (t 2 And t 3 ) I.e. as the next round (t 1 And t 2 ) And continuing to search and judge, finding out the condition meeting the target moment, and calculating a specific value of the target moment as the execution moment of the task to execute.
It should be noted that, the condition of the target time and the calculation of the target time are executed according to different formulated timing strategies, and the invention does not make specific requirements.
The invention provides a task timing strategy method, which comprises the steps of obtaining a starting time stamp for starting a timing task and a first time stamp of a current timer, and calculating a second time stamp of a next time timer according to a time interval of the timer, wherein the time interval is in a second level, judging whether a target moment for executing the timing task exists in the time interval of the current timer, and if the target moment exists, selecting the target moment as the execution moment of the timing task in the time interval of the current timer. According to the method, the dimension of the timing strategy is expanded by setting the second-level timing strategy, whether the execution time of the timing task exists in the time interval of the timer is judged, if so, the execution time of the task falls within the time interval of the timer to more accurately execute the timing task, the problem that the minute-level timing strategy cannot be executed in the time interval of the timer, and the execution time of the task is delayed due to the fact that the timer can execute until the time of the timer reaches the timing is avoided, the performance of an application program is improved, and the experience effect of a user is improved.
On the basis of the above embodiment, the determining whether the target time for executing the timing task exists in the time interval of the present timer specifically includes:
acquiring a current timing strategy, wherein the timing strategy comprises a time interval strategy and a timing moment strategy;
if the current timing strategy is a time interval strategy, traversing numbers between a first difference value and a second difference value, wherein the first difference value is a difference value between a first time stamp and a starting time stamp, and the second difference value is a difference value obtained by subtracting 1 from the difference value between the second time stamp and the starting time stamp;
judging whether the target number is an integral multiple of the time interval of the timing task in the numbers;
if so, determining that a target moment for executing a timing task exists in the time interval of the timer;
if the target time does not exist, determining that the target time for executing the timing task does not exist in the time interval of the timer.
The method comprises the steps that a current timing strategy is obtained, different timing strategies can be selected by a user according to a Web interface established by the front end and the rear end of a management system, the timing strategies comprise a time interval strategy and a timing moment strategy, and the time interval strategy is detected and executed according to a set time interval, such as interval 5s, of the timing tasks. The timing strategy is executed according to the fixed time of setting a certain timing task, such as summarizing a report in the early morning or cleaning other data. After the user selects the timing strategy, the timing strategy is sent to a program at the back end through a trigger instruction to start the task.
If the current timing strategy is the time interval strategy, the timing triggering is carried out according to the time interval strategy, a timer with an interval of N seconds (such as an interval of 5 seconds) is started in the background to detect all tasks at fixed time, and for each task, the time interval of the task is M (M)>Time stamp of recording this timer is t =n) 1 The time stamp of the next timer is t 2 Task start time stamp t 0 Traversing the number between the first difference and the second difference, whereinThe first difference is the difference t between the first timestamp and the start timestamp 1 -t 0 The second difference is the difference t obtained by subtracting 1 from the difference between the second time stamp and the starting time stamp 2 -t 0 -1, traversing t 1 -t 0 To t 2 -t 0 Numbers between-1, judging whether the target number is an integer multiple of the time interval M of the timing task in the traversed numbers, if the target number x is equal to the integer multiple of M, indicating that the timer meets the condition set by the timing strategy, waiting (x-t 1 +t 0 ) And executing after seconds, wherein the waiting target moment is the moment of executing the task to execute the task. The minimum value is the difference value of the time stamp of the present timer minus the task starting time stamp, the maximum value is the difference value of the time stamp of the next timer minus the task starting time stamp minus 1, if the number between the minimum value and the maximum value satisfies the integral multiple of the time interval of the task, the condition of task execution is satisfied, the target moment for executing the timing task is determined to exist in the time interval of the present timer, if the number does not satisfy the target moment for executing the timing task is determined to not exist in the time interval of the present timer.
In combination with the above example, the background starts a timer with an interval of 5 seconds to detect all tasks at regular time, and the task start time t is assumed that the time interval of a certain task is 8 seconds 0 Timer t of first one after task is started, which is 12:10:02 1 Time of the second timer t is 12:10:05 2 Time t of the third timer is 12:10:10 3 Time t of the fourth timer is 12:10:15 4 12:10:20, for the first timer t 1 Calculating the current timer t 1 And a task start time t 0 Corresponding to the difference in the time stamps, then calculate the next timer t 2 And a task start time t 0 The difference between the time intervals of the timer is determined to be no, namely the target time for executing the timing task does not exist in the time interval of the timer, the time t of the second timer is not executed this time, and the range is obtained to be [3,8 ], and the multiple of 8 exists between the time intervals of the timer 3 and 7 2 With or without a multiple of 8 between traversals [8,13 ], the result is that 8 is a multiple of 8,executing this time. Time t of the third timer 3 The number of times 8 between the traversals [13,18 ] is found to be a number of times 8, and 16 is executed after this time the timer 16-13=3 seconds. Wherein for t in this example 2 Is performed after waiting 8-10+2 = 0 seconds, i.e. t 2 Executing the timed task at the moment, and detecting at t the next execution task 3 Is performed after waiting 16-15+2 = 3 seconds, i.e. at t 3 The timed task is performed 3 seconds after the moment.
The method comprises the steps of obtaining a current timing strategy, traversing numbers between a first difference value and a second difference value if the current timing strategy is a time interval strategy, judging whether the numbers are integer multiples of a time interval of a timing task or not, and if the numbers are integer multiples of the time interval of the timing task, determining that the target task for executing the timing task exists in the time interval of the timer. By judging whether the execution time of the timing task exists in the time interval of the timer, if so, the execution time of the task falls in the time interval of the timer to more accurately execute the timing task.
On the basis of the above embodiment, the determining whether the target time for executing the timing task exists in the time interval of the present timer specifically includes:
acquiring a current timing strategy, wherein the timing strategy comprises a time interval strategy and a timing moment strategy;
if the current timing strategy is a timing strategy, judging whether the first time stamp and the second time stamp are on the same day;
If the time stamp is the same day, judging whether the starting time stamp is larger than or equal to the first time stamp and smaller than the second time stamp;
if so, determining that a target moment for executing a timing task exists in the time interval of the timer;
if the time interval of the timer does not exist, determining that the target moment for executing the timing task does not exist in the time interval of the timer;
if the time stamp is not the same day, the next starting time stamp of the timing task is obtained, and whether the starting time stamp is larger than or equal to the first time stamp and smaller than the second time stamp is judged;
if so, determining that a target moment for executing a timing task exists in the time interval of the timer;
if the time stamp is not stored, judging whether the next starting time stamp is greater than or equal to the first time stamp and less than the second time stamp;
if so, determining that a target moment for executing a timing task exists in the time interval of the timer;
if the target time does not exist, determining that the target time for executing the timing task does not exist in the time interval of the timer.
After the user selects the timing strategy, the timing strategy is sent to a program at the back end through a trigger instruction to start the task. The method comprises the steps that a current timing strategy is obtained as a timing strategy, the time of the timing moment of a timing task is fixed, but the timing of the timer is always calculated, the first time stamp is in the early morning of a first day and is close to the early morning of a second day, the second time stamp is in the early morning of the second day, whether the first time stamp and the second time stamp are the same day or not is needed to be judged, if the first time stamp and the second time stamp are the same day, whether the starting time stamp of the timing task is larger than or equal to the first time stamp and smaller than the second time stamp or not is judged, and if the starting time stamp of the timing task is larger than or equal to the first time stamp and smaller than the second time stamp, the target time for executing the timing task is determined to exist in a time interval of the timer; if the target time does not exist, determining that the target time for executing the timing task does not exist in the time interval of the timer.
If the first time stamp and the second time stamp are not in the same day, the next starting time stamp of the timing task needs to be acquired, and it is to be noted that the starting time stamp of the timing task is only once, after the timing task is started, the timing task is detected and executed according to the time interval of the timing task, the timing task is started and executed at a fixed time in one day, and if the time stamps of the timers are not in the same day, the starting time of the timing task in the other day is started and executed. Firstly judging whether the starting time stamp is larger than or equal to the first time stamp and smaller than the second time stamp, namely judging whether the starting time stamp is in the time interval of the present timer, if so, determining that the target moment for executing the timing task exists in the time interval of the present timer; if the time stamp is not stored, continuing to judge whether the next starting time stamp is greater than or equal to the first time stamp and less than the second time stamp; if so, determining that a target moment for executing a timing task exists in the time interval of the timer; if the target time does not exist, determining that the target time for executing the timing task does not exist in the time interval of the timer.
