Abstract
The present invention provides a kind of JAVA to unify task central dispatching method, includes the following steps: to access task by unified task api interface；The share tasks of access are distributed on local server or network server；It is lined up to task processing, the present invention passes through unified task interface, provides enough task schedule extension points, and flexibly, distributed task dispatching avoids task duplication from executing for configuration, realizes that flexible, efficient task automatically switches implementation strategy.
Description
Technical field
The invention belongs to task dispatcher technical fields, and in particular to a kind of JAVA unifies task central dispatching method.
Background technique
In computer software programming, the job scheduler of any stricti jurise all provides the directly specified execution time, deposits
Storage job information is customized to a variety of introductions and using hook and other more functions, now leads several mainstreams to be used
Job scheduler is suitble to simple scheduling such as the primary Timer scheduler of JDK, but configures simply, cannot support flexible dispatching, can only
Task serialization executes, and previous task result influences latter task, at runtime if there is a timed task, generates not
The exception of processing then all timed tasks can all stop, being affected, is holding then this current thread will stop
It needs to repeat to create when row, no thread pool concept, resource can not be shared；And simple scheduling is suitble to for thread pool task schedule,
Task execution time interval is not fixed, and is not supported complicated scheduler task, can not also be accomplished task colony dispatching；For Quartz
Task schedule is suitble to complicated scheduling, but learning difficulty is big, is not easy to grasp, and time rule change is inconvenient, cannot distinguish between level set
Group or vertical cluster.
It can see from the scheduler of above-mentioned mainstream, the various scheduling for executing scheduler are required to learn, and learning cycle is long,
Some task schedules can not accomplish distribution, and task configures disunity, more scattered, it is difficult to manage, nothing conveniently manages
From the background, it is difficult to adjustment in time, while task schedule is easily lost without persistence, is difficult to restore.Existing for the scheduler of mainstream not
Foot place, so that these schedulers are difficult to the job scheduler as a complete meaning.
Summary of the invention
According to above-mentioned elaboration, the purpose of the present invention is to provide a kind of JAVA to unify task central dispatching method, using depth
Degree encapsulation Timer task schedule, encapsulates thread pool task scheduling strategy, depth encapsulates Quartz task schedule center, and provides
Enough extension points configure for customizing on task schedule line, realize integrated distributed lock, integrated distributed task schedule is kept away
Exempt from task duplication execution.
Technical solution provided by the invention:
A kind of JAVA unifies task central dispatching method, includes the following steps:
Q1, pass through unified task api interface, access task；
Q2, by task dispatcher, the share tasks of access are distributed on local server or network server；
Q3, it is selected in any local server or network server after idle server is connected to task, the service of calling is held
Row then calls service execution to finish, if implementing result is unsuccessful, system judges failure cause, according to mistake such as implementing result success
Lose reason, task is divided into: 1, mistake can not execute, then cancel calling, and 2, can execute, then task, which enters to retry, executes team
Column；
Q4, task are lined up in retrying execution queue and enter the step of retrying execution program, repeating Q3, task when such
Cancel, then cancels calling；
In retrying execution queue, logger task, which enters to retry, executes program number, given threshold, to entrance for Q5, task
It retries and executes queue task and judge, judgement retries task type every time, and after activation threshold value, then task enters team to be checked
Column when judging to need to retry execution, into queue is retried, when judgement can not retry, are then held when non-activation threshold value into cancellation
Row queue；
Q6, in cancelling queue, such as cancel Mission Success, then task complete, such as cancel task it is failed, then enter
Q4 step；
Q7, the task in queue to be checked is analyzed, if judgement can not execute, then terminates to call, as needed to continue to hold
Row then enters Q5 step.
The present invention passes through unified task interface, provides enough task schedule extension points, configuration is flexible, distributed task scheduling tune
Degree, avoids task duplication from executing, and realizes that flexible, efficient task automatically switches implementation strategy.
Detailed description of the invention
Fig. 1 is flow diagram of the invention.
Specific embodiment
Technical solution of the present invention is clearly and completely described in following accompanying drawings combination specific embodiment, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this hair
The range of bright protection.
According to Fig. 1, a kind of JAVA unifies task central dispatching method, includes the following steps:
Q1, pass through unified task api interface, access task；
Q2, by task dispatcher, the share tasks of access are distributed on local server or network server；
Q3, it is selected in any local server or network server after idle server is connected to task, the service of calling is held
Row then calls service execution to finish, if implementing result is unsuccessful, system judges failure cause, according to mistake such as implementing result success
Lose reason, task is divided into: 1, mistake can not execute, then cancel calling, and 2, can execute, then task, which enters to retry, executes team
Column；
Q4, task are lined up in retrying execution queue and enter the step of retrying execution program, repeating Q3, task when such
Cancel, then cancels calling；
In retrying execution queue, logger task, which enters to retry, executes program number, given threshold, to entrance for Q5, task
It retries and executes queue task and judge, judgement retries task type every time, and after activation threshold value, then task enters team to be checked
Column when judging to need to retry execution, into queue is retried, when judgement can not retry, are then held when non-activation threshold value into cancellation
Row queue；
Q6, in cancelling queue, such as cancel Mission Success, then task complete, such as cancel task it is failed, then enter
Q4 step；
Q7, the task in queue to be checked is analyzed, if judgement can not execute, then terminates to call, as needed to continue to hold
Row then enters Q5 step.
The foregoing describe basic principle of the invention and advantages.It should be understood by those skilled in the art that the present invention not by
The limitation of above-mentioned case study on implementation is merely illustrated the principles of the invention described in above-mentioned case study on implementation and specification, is not being departed from
Under the premise of spirit and scope of the invention, various changes and improvements may be made to the invention, these changes and improvements both fall within requirement
In the scope of the invention of protection.Claimed range of the invention is defined by the appending claims and its equivalent thereof.
