It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
Fig. 1 is the method for processing overtime task according to an embodiment of the present invention.As an embodiment of the present invention, as schemed
Shown in 1, the method for the processing overtime task may include:
Step 101, first task data are stored in database profession, the second task data is stored in each example
In depositing；Wherein, the information attribute of second task data belongs to a part of the information attribute of the first task data.
In this step, first task data are stored in database profession, the second task data are stored each to cluster
In the memory of example, basic data is provided for subsequent step.Also, the information attribute of second task data belongs to described
A part of the information attribute of one task data；Wherein, the information attribute may include task time-out time, task status.
As an embodiment of the present invention, the information attribute of the first task data includes at least task time-out time and task shape
State, the information attribute of second task data include task time-out time, are stored with the data in each example memory of simplification,
Basic data is provided simultaneously for subsequent step.
As another embodiment of the invention, the information attributes of the first task data include at least O/No.,
The task time-out time and task status of order, the information attribute of second task data include times of O/No. and order
Business time-out time.It should be noted that each order has globally unique number, each order can correspond to multinomial wait locate
The task of reason, such as pay, deliver, return goods, exchange goods, cancel an order, complain, examine.Optionally, the order can be purchase
Object order, delivery order, audit order etc..
It should be pointed out that be stored in the database global O/No., the corresponding each task of each order,
The time-out time of each task, each task task status (such as new order, pending payment, payment are completed, payment time-out, to
Delivery, delivery are completed, delivery is overtime, wait completion of returning goods, exchange goods, examination & approval time-out etc.).Further, the first task data
Information attribute at least further include each task task status.Optionally, the information attribute of the first task data may be used also
To include sorting code number when task processing is abnormal；It can also include the timestamp information of task deposit database.
By taking the payment task of order as an example, for database as global resource, the order data structure in database is as follows:
Optionally, the classification when information attribute of second task data does not include: task status, task processing exception
Coding, timestamp information of task deposit memory etc..In an embodiment of the present invention, the information attribute of second task data
The time-out time of O/No. and the corresponding each task of each order can be only included.Optionally, second task data
Information attribute can be made of O/No. and task time-out time.
By taking the payment task of order as an example, HashSet structure is can be used in the order data structure in cluster instance memory, such as
Under:
For example, for 120 tasks (for example, it may be the payment task of 60 orders and complain task, can also be with
It is the shipping tasks of 120 orders, can also be the payment task of 30 orders, shipping tasks, task of exchanging goods, cancels an order and appoint
Business) and 10 examples, 120 tasks can be averagely allocated to 10 examples (in each example memory 10 tasks of storage and
The time-out time of each task).It can also be according to the height of each instance processes ability, to each example allocation different number
Task, so that optimized allocation of resources, saves resource overhead.
It may also is that being distributed according to the difference of task definition (such as pay, deliver, return goods, cancel an order, complain)
Task.Specifically, for example, the identical task of task definition is distributed into the same example, the instance processes these
Business.For complex disposal process or processing time longer task, the identical task of task definition can be distributed to multiple
Example, so that optimized allocation of resources, improves treatment effeciency.The multi-task can also be distributed to the same example to handle, originally
Invention to this with no restriction.
Optionally, each example of cluster uses distributed deployment (such as ZooKeeper), is taking into account horizontal extension ability
Meanwhile task data is oriented to all example parallel processings in cluster, treatment effeciency is promoted, failure risk is reduced.
As an embodiment of the present invention, the first task data stored in the database include each example memory
Second task data of middle storage, and each example the second task data stored in memory is different.That is, each
A example O/No. stored in memory is possible to identical, task be also possible to it is identical, but generally will not be in each example
The identical task data of identical O/No. and the same O/No. is stored in memory.
As it can be seen that in an embodiment of the present invention, can simplify the data storage in each example local memory, using this hair
The data storage method that bright embodiment provides, can be improved the efficiency of reading data, to reduce time overhead.
As another embodiment of the invention, the step 101 includes: that first task data are first stored in database
In, then the second task data is stored in memory.In this embodiment, database success is stored in first task data
Afterwards, then by the second task data it is stored in memory, to guarantee the data validity of database, can be based in the next steps
First task data in database execute task.
As another embodiment of the invention, step 101 may include: to receive the task processing request of user；According to
The task processing request, generates first task data and the second task data.
It should be pointed out that at the time of time-out time refers to task time-out, i.e. cut-off to what moment (such as 2017 11
10 divide 20 seconds when month 20 days 01), if the task is thrown away untreated, which belongs to overtime task.
Specifically, it can be directed to different task definitions, different timeout thresholds is set.By taking payment task as an example, time-out
Threshold value can be 24 hours or 0.5 hour, and when receiving the task requests of user, the current time adds time threshold,
As pay the time-out time of task.By taking shipping tasks as an example, timeout threshold can be 2 days or 7 days, when receiving user's
When task requests, the current time adds time threshold, the as time-out time of shipping tasks.Therefore, the time-out time can
It is determined with time and timeout threshold according to task requests, calculates time-out time, in a step 101 in order in subsequent step
It is whether overtime that task is quickly determined in rapid.
As yet another embodiment of the present invention, step 101 may include: to receive task processing request first, then root
Request is handled according to the task and generates first task data, is then stored in database profession first task data；It generates later
Second task data is finally stored in the memory of each example by the second task data.Wherein, the first task data
Information attribute includes at least task time-out time and task status, and the information attribute of second task data includes task time-out
Time.
In this embodiment, the task requests of user are first received, then generate first task number according to the task requests
According to, first task data be stored in database success and then according to the task requests generate the second task data, then
Second task data is stored in memory, to guarantee the data validity of database.If first task data are stored in data
Library failure, then terminate.It should be noted that the second task data can also be generated while generating first task data；But
It is after first task data are stored in database success, the second task data to be stored in the memory of each example.
Step 102, it according to second task data, obtains and handles overtime task.
In this step, then scanning memory first is filtered out with obtaining the second task data according to task time-out time
Overtime task reprocesses the overtime task.
As another embodiment of the invention, step 102 includes: to scan the memory first, is stored in institute to obtain
State the second task data in memory；Then, compare the task time-out time of current time Yu second task data, judge
Whether current time is more than the task time-out time；If so, handling the corresponding overtime task of the task time-out time；If
It is no, then terminate, waiting scans next time.
Optionally, the memory is scanned, periodically to obtain the second task data.Optionally, using single thread or more
The mode of thread handles overtime task.
It should be noted that since the information attribute of the second task data includes task time-out time, then, in scanning
When depositing, it can be determined that whether each task is overtime at current time.If so, the task is overtime task；If it is not, then this
Business is not a time out task.
It should be pointed out that also the task in normal time is being handled, if task exists while handling overtime task
Processing is completed in normal time, which is deleted from memory.As it can be seen that the second task data being stored in memory is constantly
It updates.In fact, the second task data is task data to be processed.
Optionally, all examples can be used Spring+Quartz mode and configure starting in cluster, and each example is from respective
Overtime order is obtained in local memory.Since the embodiment of the present invention exists original global Task-decomposing at several subtasks
It is handled respectively in each example, therefore, significantly reduces the property of individual machine instance processes synchronization high-volume overtime task
It can pressure.
It should be pointed out that the prior art when handling each overtime task, needs first from each operation system in example
(such as ordering system, custom system, commodity information system etc.) foraging task basic data (such as mission bit stream, user information,
Merchandise news etc.), then these task basic datas are associated with and are assembled, generate task data, then newly drive journey processing time-out into
Task.And in an embodiment of the present invention, without being associated and assembling in example, only by task time-out time
It determines overtime task, then realizes the processing to overtime task.As it can be seen that the embodiment of the present invention makes full use of distributed proccessing
With memory treatment effeciency advantage, the treatment effeciency of overtime task is improved.
Step 103, the corresponding first task data of the overtime task and the second task data are updated.
Specifically, in this step, the task of the corresponding first task data of overtime task handled in step 102 is updated
State deletes corresponding second task data of the overtime task.
Optionally, after processing overtime task success, the task status of first task data is first updated；When being updated successfully
Afterwards, then the second task data is deleted, to guarantee the data validity of database.
By taking payment task as an example, after processing overtime task success, first by the task status orderState of overtime task
It is revised as " payment is completed " from " pending payment ", then deletes the overtime task in memory.Therefore, each example is stored in memory super
When task quantity may remain in certain amount grade, avoid occupying a large amount of memories.
Fig. 2 be according to the present invention one can refer to embodiment processing overtime task method main flow signal
Figure.As another embodiment of the invention, step 102 and step 103 can be specifically included:
Timing scan example memory；
The second task data is obtained from the memory；
The task time-out time for comparing current time Yu second task data, judges whether there is overtime task；
Overtime task if it does not exist then terminates；
Overtime task if it exists, then using single thread/multi-thread data processing mode processing overtime task；
After processing overtime task success, the task status of the corresponding first task data of the overtime task is first updated；
After being updated successfully, then delete corresponding second task data of the overtime task.
According to various embodiments recited above, it can be seen that the present invention is stored in number by using by first task data
According in library, the second task data is stored in the memory of each example, according to second task data, obtains and handle super
When task technological means, to solve the problems, such as that task treatment effeciency is low, resource overhead is big.That is, the prior art
It is that individual machine example in synchronization needs to handle large batch of overtime task, when overtime task reaches certain magnitude and business
When system is various, some unnecessary resource overheads are increased.And the present invention is to be stored in database profession first task data,
Second task data is stored in the memory of each example, according to second task data, obtains and handle overtime task,
To handle original global Task-decomposing respectively in each example at several subtasks, single reality is significantly reduced
The performance pressures of example processing synchronization high-volume overtime task.
Moreover, overtime task is assured that by the time-out time of task without being associated and assembling in example,
Then the processing to overtime task is realized.As it can be seen that the embodiment of the present invention makes full use of distributed proccessing and memory to handle effect
Rate advantage improves the treatment effeciency of overtime task.
As yet another embodiment of the present invention, the method can also include:
Step 104, if the second task data is stored in the memory of each example, according to second task data
Obtain and handle occur in any one steps of overtime task first task data corresponding with the overtime task is updated it is different
Often, then exception information is stored in the database；And
Step 105, the exception information in the database is obtained, is chosen according to policy library and corresponds to the exception information
Strategy, and the exception is handled according to the strategy.
Specifically, in a step 101, if occurring when the second task data to be stored in the memory of each example different
Often, then exception information is stored in database；In a step 102, if in timing scan, obtaining the second task data, determining super
When task, occur in any one step in overtime task processing abnormal, then exception information is stored in database；In step
In 103, if there is exception when updating the task status of the corresponding first task data of overtime task, exception information is stored in
In database.And then according to exception information, carry out abnormal retry.
For ease of description, the exception occurred in above-mentioned steps 101, step 102, step 103 is classified as " process by the present invention
It is abnormal ".
If being pointed out that, Fig. 2 exemplarily only indicates exception occur at " updating task status ", causes to update and lose
It loses, then exception information is stored in database, carry out abnormal retry.Similarly, occur exception in executing other steps, also will
Exception information is stored in database, is carried out exception and is retried, repeats no more.
In yet another embodiment of the present invention, since the information attribute of the first task data can also include task
Sorting code number (errorType) when processing is abnormal.Optionally, it after exception information is stored in the database, updates
The first task data, such as sorting code number (errorType) when order processing exception, in order to according to order processing exception
When sorting code number determine corresponding strategy.
Optionally, exception information is periodically obtained from database.Such as order time-out is obtained periodically from database
The abnormal order of processing (isFinish=0 and errorType is not empty).
Optionally, it can also be triggered by event, when the event triggers, obtain the exception information in the database, according to
Policy library chooses the strategy for corresponding to the exception information, then handles the exception according to the strategy.For example, in urgent feelings
Under condition, abnormal order can walk designated lane using event trigger mechanism by separate interface, to handle abnormal order.
It, therefore, can be according to from plan it should be noted that be stored in the policy library corresponding to various abnormal strategies
The strategy slightly chosen in library executes corresponding processing.
Optionally, the exception can also include system exception and/or data exception.Optionally, the system exception packet
Include example on-hook, network connection is abnormal, example memory has been expired, database access is abnormal, caching read-write is abnormal etc..Optionally, institute
It states the information that data exception may include order to be altered, causes to occur abnormal.Similarly, different for system exception and data
Often, strategy corresponding thereto can also be selected from policy library.
Fig. 3 is another signal that can refer to the main flow of the method for the processing overtime task of embodiment according to the present invention
Figure, the method for handling overtime task may include:
It is triggered by clocked flip or event, exception information is obtained from database, judges whether there is exception information；
Exception information if it does not exist then terminates；
Exception information if it exists then determines abnormal type according to the exception information, for example process is abnormal, system is different
Often, data exception or other unknown exceptions；
The strategy for corresponding to the Exception Type is chosen according to policy library；
If the Exception Type is that process is abnormal, the first task data in database are called, and handles time-out and appoints
Business；If processing is unsuccessful, the first task data in database are called again, and handle overtime task, until handling successfully；
Then task status (the note of the exception information i.e. more in new database of the overtime task in first task data is updated
Record)；
In process exception, according to number of retries threshold value and/or time threshold can be retried decide whether to continue to retry.If
Not up to number of retries threshold value and/or time threshold is retried, then continue growing call number, dispatched again, if being more than weight
It tries frequency threshold value and/or retries time threshold, then issue and remind to responsible person.Specifically, number of retries threshold can be preset
It is worth and retries time threshold, if exceeding threshold value, no longer retries, and issue prompting, to notify responsible person, so as to pass through people
The mode of work carries out overtime task processing or waits next round triggering.It should be noted that can also be further directed to: will
Second task data is stored in the memory of each example, obtains and handle overtime task and more according to second task data
There is exception in any one step of new first task data, formulates different strategies respectively, and these policy stores are existed
In policy library.
If the Exception Type is system exception, no longer retry, and issue prompting, to notify responsible person, so as to
By manually carrying out abnormality processing.After artificial treatment, the record of the exception information in more new database.It can also be further
Statistic of classification is carried out according to the details of system exception.After a period of time, by system exception and data exception, process abnormal one
It rises and forms statistical table, be mainly used for analyzing various exceptions shared ratio when overtime task retracts.
If the Exception Type is data exception, abandons, no longer retry, and the shape of the order in more new database
State value, so that the order for data exception occur is not re-used as exception in next round triggering.
If the Exception Type is other unknown exceptions, no longer retry, and issue prompting, to notify responsible person, from
