As Figure 2-3, a kind of to take turns the system for executing delay queue based on the time, including interface module, database, recall
Module, execution module, judgment module, state update module and cleaning modul.
Interface module is task registration interface, for receiving delay dispatching task.In the present embodiment, interface module includes
com、zbj、trade、delay、api、service、DelayService、invoke。
Database is for saving delay dispatching task.In the present embodiment, delay dispatching task is registered to by interface module
In system and save in the database.In the present embodiment, database uses MySQL database.
Module is recalled for recalling the delay dispatching task in database into delay queue.In the present embodiment, delay is adjusted
Degree task includes that the delay dispatching task of new registration and reception meet or exceed the delay dispatching that the expected time is still not carried out and appoint
Business.Delay queue uses Delay Queue.Expected time is exactly the time of default.
Delay Queue is a unbounded obstruction queue, only could therefrom extract element when delay expires.The queue
Head be delay expire after the holding time longest Delayed element.
Execution module executes the delay dispatching task for recalling module for timing.In the present embodiment, execution module is
Expect.exe (time) executes interface, and the time of execution is arranged by the way that the value of time is arranged.
Judgment module is for judging whether delay dispatching task runs succeeded.In the present embodiment, judging result value passes through
Dubbo interface returns.
State update module is used to update the state of the delay dispatching task.In the present embodiment, state update module is
The time of more new state is arranged by the way that the value of time is arranged in expect (time).The state of delay dispatching task is divided into wait hold
In row, execution, three kinds are executed.
Delay dispatching task of the cleaning modul for having been executed in timing Clean Up Database.In the present embodiment, cleaning modul
For DataScheduleService.invoke, retain 15 days data.
In the present embodiment, it is based on Netty framework establishment that system, which is delay dispatching system,.
As shown in Figure 1, a kind of take turns the method for executing delay queue based on the time, comprising the following steps:
S1, creation dubbo interface create delay dispatching task.By configuring dubbo interface, the corresponding creation of different interfaces
Different size of delay dispatching task, to establish different size of delay queue.
First the delay dispatching task scan entry time wheel of creation, then configured according to database, interface concurrent
Number size, the thread pool for creating corresponding corresponding size carry out the execution of delay dispatching task.
S2, registration delays scheduler task to delay dispatching system.
In the present embodiment, the concrete methods of realizing of step S2 are as follows: be inserted into delay dispatching task by task registration interface
Into the database of delay dispatching system.Specifically: the task registration interface (com.zbj.t for calling delay dispatching system to provide
), rade.delay.api.service.DelayService.invoke by delay dispatching task registration to delay dispatching system
Database in.
S3, the state for updating delay dispatching task in required time.
Concrete methods of realizing in step S3 are as follows:
S3.1, the data of new delay dispatching task are swept into delay queue from the database of delay dispatching system,
And according to the parameter more new state of expect (time)；
S3.2, the delay dispatching task for being up to or being still not carried out more than the expected time data according to expect (time)
Parameter more new state lay equal stress on and be newly swept into delay queue.
S4, delay dispatching system time wheel in required time by expect.exe (time) execute interface execute delay
Scheduler task.
In the present embodiment, the time wheel of delay dispatching system is HashedWheelTimer.
HashedWheelTimer is mainly used to a large amount of timed tasks of efficient process.HashedWheelTimer can be managed
Solution is Set<Task>[] array, and each slot position (slot) indicates a Set<Task>.HashedWheelTimer has two
A important parameter:
Tick Duration: every tick primary time interval, every tick will once reach next slot position；
TicksPerWheel: the slot number in wheel；
Assuming that the time wheel of a ticksPerWheel=8, to tick Duration=100ms, then 800ms can be walked
A complete circle, after timer.start (), just starts tick, every tick is primary, and timer can will record tick times total number
ticks.When a new overtime task is added in we, it can be calculated according to the time-out time of the task of time-out and wheel time started time
Out it should slot position.
S5, judge whether delay dispatching task runs succeeded and update the state of the delay dispatching task after being performed.Tool
Body are as follows:
S5.1, judge whether delay dispatching task runs succeeded, and judging result value is returned by dubbo interface.
S5.2, the state of the delay dispatching task after executing is updated according to judging result value and is stored in database.If holding
It goes successfully, return judging result value is true, and more new state is to have executed；If executing failure, returning to judging result value is
False, more new state are to be not carried out.
State is the delay dispatching task executed in S6, timing cleaning Clean Up Database.In the present embodiment, timing
It is 15 days, i.e., the execution data every 15 days, before cleaning 15 days.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
