The not high enough problem of the execution accuracy of business, to promote the execution accuracy of timed task.Multiple embodiments will be passed through below
The method and device that task is executed to the timing of the present invention is described in detail.
With reference to figure 1, Fig. 1 is the method flow diagram that a kind of timing that one embodiment of the present of invention provides executes task, this
In embodiment, as shown in Figure 1, the method that the timing executes task includes the following steps：
Step 101 obtains preset heartbeat control frequency and preset task execution condition；Wherein, institute
It includes the timing information executed needed for timed task to state task execution condition.
To solve the problems, such as that timed task execution precision of the existing technology is not high enough, the present invention provides one kind to be based on
The timing of heartbeat control executes the scheme of task.
In consideration of it, when realizing the execution of timed task, preset heartbeat control frequency need to be obtained first.The heartbeat
Controlling frequency supports the frequency of s (second) precision grade and higher precision rank such as ms (millisecond) grade to set, can in practical application
Heartbeat is carried out according to the available accuracy demand of its pending task control frequency by related personnel such as technical staff or user etc.
Setting.
Simultaneously because the execution of timed task needs, using corresponding conditions as triggering foundation, to also need to obtain timing to appoint
The task execution condition of business, the task execution condition of timed task, which generally comprises the related timing executed needed for timed task, to be believed
Breath, the timing information can specifically include but are not limited to time started, end time, repeat number and repeat
Time interval etc..
Step 102 is based on scheduled reference instant, carries out timing using heartbeat control frequency, obtains clocking information.
The reference instant can equally be preset by technical staff or user according to its actual demand, specifically, than
Such as, only (certain timed task such as need to be executed in certain day 6:00 AM for the timed task that certain time point single executes for one
Deng), then can by the zero of the same day when (time can read from the time module of time server or system) on the basis of the moment, open
Begin to carry out timing using heartbeat control frequency, subsequently when timing duration reaches 6 hours, then can perform single timing and appoint
Business.
It for another example, then can be with last timed task for one needs to recycle and executes multiple timed task
Finish time on the basis of the moment, start with heartbeat control frequency be when the execution of previous timed task carries out timing,
Such as, it is assumed that it was just recycled at interval of 10 minutes and executes a timed task, then it specifically can be in the end of upper primary timed task
Moment, 10 minutes when starting with heartbeat control frequency meter, subsequently when timing duration reaches 10 minutes, can start into
The task execution process of this timed task of row.
Here, it should be noted that timing is carried out based on heartbeat control frequency in the present invention, essentially refers to be based on the heart
It jumps control frequency to be counted, and according to the accumulated number of counting, knows its corresponding duration, for example, it is assumed that in advance
The heartbeat set controls frequency as 1000Hz, then when being counted based on heartbeat control frequency, when the accumulated number of counting
Reach 6*105When, corresponding timing duration reaches 10 minutes.In practical application, can be used numerical value be incremented by or numerical value increase and decrease
Mode carries out timing using set heartbeat control frequency, for example, for 10 minutes timing durations, can be used count value from
0 is incremented to 6*105Mode carry out the timing of the duration, can also use from 6*1050 mode is decremented to complete the duration
Timing, the present invention is not construed as limiting its timing mode.
Step 103, according to the clocking information and the timing information, it is described fixed to judge currently whether need to start to execute
When task.
As it was noted above, the timing information can include but is not limited to time started, end time, repeat time
The relevant information for the task execution condition as timed task such as number, the time interval repeated, in consideration of it, utilizing
On the basis of the heartbeat control frequency carries out timing, it can be based on the clocking information and the timing information, to judge to work as
It is preceding whether to need to start to execute the timed task.
Specifically, such as, it is assumed that the time interval that multiple timing task need to be repeated, and executed every time be 10 minutes,
Then after upper primary timed task executes end and carries out timing based on finish time, when based on set heartbeat control frequency
1000Hz is from 0 incremental count to 6*105(or from 6*105When counting down to 0), correspondingly indicate that timing duration has reached 10 points
Clock needs to start to execute to work as previous timed task to have reached the Starting Executing Time for working as previous timed task；Otherwise,
If count value is not up to 6*105(or not being decremented to 0) then indicates the Starting Executing Time for also not up to working as previous timed task, from
And it needs to continue to count.
Step 104, if so, starting to execute the timed task.
If according to the clocking information and the timing information, judge that currently needing to start to execute the timing appoints
Business, for example judge that current time has reached the Starting Executing Time etc. of timed task, then this step starts to execute the timing
Task, to realize the timed task implementation procedure controlled based on heartbeat.
As it can be seen from the above scheme the method that timing provided in this embodiment executes task, including obtain the preset heart
Jump control frequency and preset task execution condition；Wherein, the task execution condition includes executing timed task institute
The timing information needed；Based on scheduled reference instant, timing is carried out using heartbeat control frequency, obtains clocking information；Root
According to the clocking information and the timing information, whether judgement currently needs to start to execute the timed task；If so, starting
Execute the timed task.It can be seen that the invention discloses the realization sides that a kind of timing based on heartbeat control executes task
Case can be higher precision grade (such as ms ranks) by the way that heartbeat is controlled set of frequency, to incite somebody to action using application scheme
Accordingly control can have in higher precision grade (such as ms ranks) to apply the present invention program the execution precision of timed task
Effect promotes the execution accuracy of timed task.
In the next embodiment of the present invention, continues to provide and obtain preset task execution in the step 101
A kind of possible realization method of condition, with reference to Fig. 2 shows timing execute the method flow diagram of task, in the present embodiment, institute
It states and obtains preset task execution condition in step 101, can be realized by processing procedure below：
The task execution condition for the regular expression form that step 1011, acquisition are generated in advance based on Target Setting Mode
Or the task execution condition of XML (Extensible Markup Language, extensible markup language) linguistic form.
In the prior art, the sentence of the task execution condition of timed task is arranged, only supports regular expression form,
That is, the prior art is only capable of generating the task execution condition of timed task in the form of regular expression, and canonical table
Versatility up to formula is relatively low, cross-platform can not use.
To solve this problem, the present invention is on the basis of can support regular expression, it is also proposed that use XML language shape
Formula carries out the generation of task execution condition sentence, when the present invention program is embodied, can be parsed by developing in advance
The correlative code of the task execution condition of XML language form, to realize the task execution condition sentence progress to XML language form
Parsing, is realized with this on the basis of can support regular expression, additionally it is possible to XML language is supported, to timed task
Task execution condition when being configured, the form of regular expression or XML language can be used and held to generate required task
Row condition.
Compared to regular expression, the versatility of XML language is preferable, cross-platform can use, to which the present embodiment passes through
It supports the task execution condition sentence based on XML language form, improves the versatility of system, cross-platform can use.
In another next embodiment of the present invention, continue to illustrate the Setting pattern of timed task.
In the prior art, when the conditional statement to task execution condition is configured, the Setting pattern of conditional statement compared with
It is single, underaction is set.To solve the problems, such as this, in the present embodiment, three kinds be configured to task execution condition are provided
Setting pattern：First Setting pattern, the second Setting pattern, third Setting pattern enable to support more flexible condition
Sentence is arranged.
Wherein, first Setting pattern is used to indicate executes multiple timing at predetermined intervals in the scheduled time
Task；Timing parameters defined in the pattern include time started (start-time), end time (end-time), repeat to hold
Places number (repeat-count) and the time interval (repeat-interval) repeated.
For example, it is assumed that the execution of timed task need to be from 10:00 starts, and 18:00 terminates, wherein repeats 5 timings and appoints
Business, every minor tick 10 minutes, the then task execution condition that can generate the timed task based on first Setting pattern.
Specifically, the task execution condition sentence of regular expression form generated based on first Setting pattern is：
mode1:H/10:00 H/18:00 5M/10；
The task execution condition sentence of XML form generated based on first Setting pattern is：
<mode1>
<condition>H/10:00 H/18:00 5M/10</condition>
</mode1>。
Second Setting pattern is used to indicate each time point in multiple predetermined point of time within a predetermined period of time
Execute multiple timing task；Timing parameters defined in the Setting pattern include：The execution period (dual-time, support year,
The moon, day, hour, minute), predetermined point of time (do-time, i.e., scheduled one or more particular point in time), repeat time
Number (repeat-count) and the time interval (repeat-interval) repeated.
For example, it is assumed that timed task need to execute in one day, and specifically in 8 points, 12 points, 20 points of execution tasks, and every
A time point (8 points, 12 points, 20 points) repeats 5 times, and every minor tick 10 minutes can then be based on the second Setting pattern next life
At the task execution condition of the timed task.
Specifically, the task execution condition sentence of regular expression form generated based on second Setting pattern is：
mode2:D/1 H/8,12,20 5 M/5；
The task execution condition sentence of XML form generated based on second Setting pattern is：
<mode2>
<condition>D/1 H/8,12,20 5 M/5</condition>
</mode2>
The third Setting pattern is used to indicate the schedule based on calendar and executes timed task；The pattern corresponds to definition
There is the parameter of 7 dimensions：Second, minute, hour, which day in one month, month, which day in one week, the time.
For example, it is assumed that timed task need to be on every Mondays, and Tuesday, Wednesday, the evening 20 of Saturday:00 to 23:00 executes, and every
Half an hour executes primary, the then task execution condition that can generate the timed task based on the third Setting pattern.
Specifically, the task execution condition sentence of regular expression form generated based on the third Setting pattern is：
mode3:0 0/30 20-23*MON-WED,SAT*；
The task execution condition sentence of XML form generated based on the third Setting pattern is：
<mode3>
<condition>0 0/30 20-23*MON-WED,SAT*</condition>
</mode3>
It, can after the task execution condition for generating regular expression form or XML language form based on corresponding Setting pattern
The task execution condition sentence of the regular expression form of generation or XML language form is preserved in systems for spare.
The present embodiment by providing three of the above Setting pattern, overcome the Setting pattern of conditional statement in the prior art compared with
The problem of being single, underaction be set, so as to support more flexible conditional statement setting.

First create a thread pool for including multiple threads, for example establishment one includes the thread pool etc. of 10 threads, on this basis, when up to
When to task execution time, the task can be executed based on the idle thread in the thread pool.
When it is multiple that a certain moment, which needs the quantity of the timed task executed, that is, there are multiple timed tasks while reaching and appoint
When business executes the time, each task can be performed in parallel based on multiple idle threads in thread pool, wherein per thread exists
Synchronization is only capable of executing a task.If the task quantity for reaching the execution time is more, the thread that leaves unused in thread pool is had exceeded
Quantity, then the corresponding task beyond idle number of threads, can be waited for, until some task execution complete from
And after so that its corresponding thread is idle, the thread that this could be utilized idle executes being waited for for the task.
As an example it is assumed that including 10 threads altogether in thread pool, then can at most be executed parallel by being based on the thread pool by 10
Task, and for the task beyond the quantity, then it needs to be waited for, until occurring the thread that leaves unused again, can continue
Thread is left unused using this to execute being waited for for task.
