The embodiment of the present invention creates flow of event during the circulation of workflow task state, and the flow of event can include more
Individual event, the event are to obtain the intermediate links of workflow task state according to advance Definition of Division；The flow of event
At least one snapshot can also be included, each snapshot can include at least part information of the flow of event at single time point
Set, it follows that snapshot completes each event and event information of circulation before being recorded in the time point for creating snapshot.
When the workflow task state occurs abnormal, the event information recorded by searching newest available snapshot can recover phase
The event answered.Technical solution of the present invention can be recalled from newest available snapshot incision event, on the one hand because snapshot records
Event information can recover the state-event of directed cyclic graph, on the other hand can avoid recalling whole event stream again, drop
The complexity of low event recovery process, efficiently recover anomalous event so as to realize, improve event and recover efficiency.
It is understandable to enable above-mentioned purpose, feature and the beneficial effect of the present invention to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of invention is described in detail.
Fig. 1 is a kind of schematic flow sheet of the restoration methods of workflow task state of the embodiment of the present invention.The work
Flow the change of task status and circulation process often correspond to the implementation procedure of a task.In the workflow task state stream
Flow of event is created during turning, the flow of event can include multiple events and at least one snapshot, and the event is to work
The intermediate links of task status are flowed according to advance Definition of Division；Each snapshot can include the flow of event at single time point
At least part information set, namely in some individual event point, some or all of information in flow of event.Work as institute
Workflow task state is stated when occurring abnormal during circulation, the event information that can be recorded by newest available snapshot is extensive
The event of the advance Definition of Division of workflow task state is directed to again, so as to stream task status of resuming work.
Further, the restoration methods of the workflow task state shown in Fig. 1 may comprise steps of：
Step S101：Flow of event is created during the circulation of workflow task state, the flow of event includes multiple events
With at least one snapshot, each snapshot includes set of the flow of event at least part information at single time point；
Step S102：When the workflow task state occurs abnormal, according to newest available snapshot to the event
Event in stream is recalled.
Specifically, before the circulation of workflow task state, the circulation to the workflow task state in advance can be used
The multiple events of Definition of Division, a specific circulation caused by during workflow task state circulation described in each representations of events
Link.In step S101, flow of event is created during the circulation of workflow task state, the flow of event can include more
Individual event, by the circulation of each event, complete flow of event can be formed.
The flow of event can also include a snapshot or multiple snapshots.Snapshot is circulated in the workflow task state
During complete create.It can predefine snapshot quantity to be created before creating snapshot and be the workflow task shape
Which of state circulation process or which event create snapshot.In general, if one or more events complete stage sex work
After can create snapshot.The establishment process of snapshot depends on event (namely intermediate links) state of flow of event, is in flow of event
Circulation during complete.
Generally, can be had by snapshot being created during the circulation of the workflow task state or flow of event by two kinds
Mode.One kind is to create snapshot according to preset trigger condition, namely during the circulation of workflow task state, if met pre-
If trigger condition, then automatic triggering creates snapshot；Another kind is manual creation snapshot, namely flowed through in workflow task state
Cheng Zhong, triggering creates snapshot manually as needed.In actual applications, to meet different application business demand, some specific
, it is necessary to increase snapshot temporarily to record event information in scene, now snapshot can be created by the way of manual creation snapshot.
For example, occurring accident during the circulation of workflow task state, the accident is not belonging to advance Definition of Division
Event when, can be the accident manual creation snapshot to record the actual information of accident, flexible adaptation is actual
Business demand.
As a not limiting example, if preset trigger condition includes completing billable events, completes regularly to go out on line
Tool invoice event, completion bill collect event, then during task stream mode circulation, will be arrived respectively in circulation
Invoice event is regularly provided in the billable events, the line, the bill collects automatic triggering establishment snapshot after event.If
Invoice event will be regularly provided on line and is changed under line provide invoice event immediately because business needs, then in such case
Under, it is possible to it is to provide invoice event immediately under line to trigger establishment snapshot manually.
Further, the purpose for creating snapshot is all or part of thing in order to record the flow of event at single time point
The information aggregate of part.Specifically, described information set can include following one or more：Event generation time, type, version
This, the cycle-index of state machine and each state, business datum etc., the business datum refers to associated with the event attached
Addend evidence.The circulation of some events may associate one or more business datums, thus in event flows through journey, often need
To handle or store simultaneously and the business datum of event correlation.For example, can be with automatic flow to button after the completion of amount of money calculating event
Bothersome part.In another example can be with automatic flow to providing invoice event after the completion of billable events.Those skilled in the art can basis
It is actually needed change and dissolves more embodiments, will not be described here.
It is noted that the state machine of some individual event and the circulation of each state can be included due to the snapshot
Number, thus the snapshot can handle the workflow task state circulation process of directed cyclic graph, without recovering whole again
Flow of event, event can be improved and recover efficiency.
Further, the snapshot is also comprising following one or more：Creation time point and snapshot state.Creation time
Point refers to create snapshot or generates the time of snapshot, for recording the creation time of snapshot.It follows that newly create (namely wound
It is newest to build time point) snapshot can get the snapshot before the flow of event that includes of each snapshot single time point letter
Breath set.Can be that snapshot sets snapshot state when creating snapshot.Because the snapshot newly created can be included in flow of event
The full detail for the event completed that circulates, thus the snapshot state of the snapshot of newest establishment can be arranged to available.When described
When workflow task state occurs abnormal, newest available snapshot backtracking event can be based on.Under certain condition, snapshot state
It can update, such as after new snapshot is created, the snapshot state of " old " snapshot before new snapshot can be arranged to not
It can use.
Further, the snapshot can also include the event identifier of all Definition of Division in advance (for example, the snapshot can
To include the event identifier for the completion that circulated before creating the snapshot, the order that each event identifier is completed according to event sorts).It is logical
The content of inquiry snapshot is crossed, the event identifier of event completed at present can be obtained, and then can be according to pre-defined
Event deduces the event identifier of the follow-up event also to be continued executing with.In addition, the snapshot can also include predefined snapshot
Quantity and recent snapshot numbering, can be obtained by the quantity of predefined snapshot and current to search any snapshot
The position of snapshot.
Further, in step s 102, can be according to newest available when the workflow task state occurs abnormal
Snapshot carry out snapshot state backtracking, and then the event in the flow of event is recalled.The backtracking of carry out event can use
Existing state machine mode is recovered.
As a not limiting example, it can specifically include following step with reference to step S102 in figure 1 and Fig. 2, Fig. 1 in the lump
Suddenly：
Step S1021：When the workflow task state occurs abnormal, updated according to the reason for described abnormal each fast
According to snapshot state, when the snapshot with it is described abnormal the reason for associate when, the snapshot state is updated to it is unavailable, otherwise
The snapshot state for keeping the snapshot is available；
Step S1022：It is available snapshot to search newest snapshot state, and impinges upon the flow of event soon according to what is found
The middle initiation event for determining backtracking；
Step S1023：Backtracking is proceeded by from the initiation event.
Specifically, in step S1021, first according to the reason for described abnormal according to the time by new and old order more
The snapshot state of new each snapshot.If snapshot with it is described abnormal the reason for do not associate, keep snapshot state, namely described
The snapshot state of snapshot is still available.If the snapshot with it is described abnormal the reason for associate when, according to the reason for described abnormal,
It is determined that the number for the snapshot being associated, and successively renewal with it is described abnormal the reason for the snapshot that associates, i.e., by snapshot state more
Newly to be unavailable, when snapshot state is unavailable, when recovering the workflow task state, ignore the snapshot.For example, thing
Part stream pre-defines event A, event B, event C and event D, and the default creation time point for creating snapshot is respectively event A
After the completion of create to create after the completion of snapshot a, event B to create after the completion of snapshot b, event C and create after the completion of snapshot c and event D
Snapshot d.Assuming that in event flows through journey, flow of event goes to event A and completed, and can now create snapshot a, while can incite somebody to action
Snapshot a snapshot state is arranged to available；Similar mode can create snapshot b, and snapshot b snapshot state is arranged to can
With now snapshot b includes event A and event B information aggregate, thus snapshot a snapshot state can be arranged into unavailable；Class
As, snapshot c can be created after the completion of event C circulations, snapshot c snapshot state is arranged to available, while by snapshot a and snapshot
B snapshot state is arranged to unavailable.If when flow of event circulates to event D from event C, exception occurs for event D, then will not create
Build snapshot d.If event D does not associate with snapshot c snapshot state, then snapshot c snapshot state is maintained as can use.Example again
Such as, the flow of event for data circulation pre-defines monovalent valuation event, billable events and provides charge authority event, and in advance
It is defined on after monovalent valuation event and creates unit price valuation snapshot, create charge snapshot after billable events, providing charge authority
Created after event and provide charge authority snapshot.When the flow of event of data circulation completes billable events, on the one hand, can be automatic
Trigger and create charge snapshot, it is available to set the snapshot state of charge snapshot, and the snapshot state of setting unit price valuation snapshot is
It is unavailable；On the other hand, the flow of event will be circulated from billable events to provide charge authority event.If now data are supplied
Side's adjustment data unit price, namely the workflow task state occur it is abnormal, and charge snapshot with it is described abnormal the reason for (namely
Monovalent valuation event, which changes, causes the workflow task abnormal state) relevant, the snapshot state of the charge snapshot
Will by it is available be updated to it is unavailable.
Further, in step S1022, can be recalled by searching snapshot state, if the snapshot found
State is unavailable, then ignores recent snapshot, advance to next snapshot and judged；When finding newest available snapshot
When, the snapshot is cut, determines to recover the initiation event of the flow of event from the snapshot.The initiation event can be institute
State in flow of event before the snapshot found and the event nearest apart from the snapshot found.
Further, in step S1023, event is recalled since the initiation event found.At this point it is possible to according to business
Need, some or all of information adoption status machine mode of some the individual event point included based on the snapshot recovers thing
Part, namely since the initiation event, continue the circulation of the workflow task state.
Summary describes, it can be seen that in data circulation, compared to existing simple event stream reset mode and biography
The state machine reset mode of system, the advantage for recovering the workflow status task based on snapshot are as follows：It is possible, firstly, to simplify work
Task status recovery process is flowed, and the workflow task state of directed cyclic graph can be handled；Secondly, can be according to snapshot state
Great-jump-forward recovers event, without recovering whole event stream again, improves event and recovers efficiency；Can be that accident is created manually
Snapshot is built, is flexibly applied to various real data circulation business.
