In one embodiment, web client 116 is initiated for example to pay and asked by network to processing system 102, or Wireless client 114 is initiated for example to pay and asked using near-field communication technology by the I/O equipment 108 of processing system 102, processing System 102 is handled payment request.As will be described in detail, processing system 102 will ask for the payment The information such as caused sequence of events, state, data is stored in storage device in processing procedure, shown here storage device It is illustrated as the first database 110 and the second database 112.For example, by all data manipulations asked for the payment store to In first database 110, also i.e. by Action Events stream persistence, and as unique trusted source of data change；And it is directed to The data of payment request will be synchronized to the second database 112 by the first database 110, the second database 112 be mainly used into The read-only inquiry operation of row.It may be noted that second database 112 is schematically show only in Fig. 1, and according to actual need Will, with mass data and when inquiring about concurrent, there may be multiple second databases in processing system 102 more.Using ring Third-party server 118 can also be included in border 100, such as in this embodiment, it can be connected by channel of disbursement Financial institution or payment mechanism etc..Pay after request is disposed, processing system 102 can to wireless client 114 and/or The feedback information of web client 116.

The technical scheme of the disclosure is described in detail below in conjunction with specific embodiment.Fig. 2 is shown according to this public affairs The flow chart of the method 200 of the one embodiment opened.

In step 202, ask to initiate transaction business, the generation multiple orders associated with transaction business in response to user. In this step, the transaction business request that processing system receives web client 116 or wireless client 114 is initiated, such as prop up Pay request, place an order request etc., the processing system generation multiple orders associated with the transaction business.In one embodiment, Processing system generates multiple orders associated with pay invoice, for example, the order of establishment pay invoice, the order of execution pay invoice, Update pay invoice order, cancel pay invoice order etc..In another embodiment, processing system generation is related to placing an order Multiple orders of connection, such as create the order that places an order, perform the list that places an order, confirm the order etc. that places an order.

In step 204, based on the execution of multiple orders, generation multiple events corresponding with multiple order difference are with shape respectively Into complete flow of event.In this step, the execution of each order in the multiple orders generated in step 202, One or more orders corresponding to generation respectively.For example, for creating pay invoice order, this is performed in processing system 102 After order, generate corresponding pay invoice and create event.In some cases, according to one order execution, can generate with Multiple events corresponding to the order.

In step 206, multiple events and the data associated with multiple events are write into the first database, and by data It is synchronized to the second database.In this step, the write operation to business datum and the separation of read operation are realized.In the first data Relevant all historical events are stored in storehouse, and are based on event by data syn-chronization to the second database.

In step 208, in response to data inquiry request, data are read from the second database.All behaviour based on inquiry Make, processing system 102 is responded with the operation to the second database.

From above procedure, it can be seen that, all operations being related to the first database 110 are all by specifically ordering Order triggering corresponding event is completed to operate, and this process is asynchronous, and all change behaviors being related to transaction business It is included in specific event, binding events are traced to the source pattern, can record all events, rather than conventional certain point Data message, these information can return as the operation note or daily record of processing system 102 to transaction business Move back or replay.The process is discussed in detail below.

Fig. 3 shows the schematic diagram of the specific implementation flow 300 of one embodiment of the disclosure.In a reality of the disclosure Apply in example, (Event Sourcing) mechanism is traced to the source to handle transaction industry based on order inquiry responsibility degree (CQRS) and event Business.In the present embodiment, user initiates to pay request by wireless client 114 or web client 116, and processing system 102 connects Receive the payment and ask included information, such as each parameter of pay invoice, such as information of order both parties, order are compiled Number, the order amount of money, order list of articles etc., the structure of processing system 102 multiple orders associated with payment request, such as create Build pay invoice order 302 and perform pay invoice order 304, and system polymerize to pay invoice, creates payment and orders The example of single polyase 13 06.Each polymerization or polymerization example is identified by unique identifier respectively.Polyase 13 06 is typically based on Domain model and build, it polymerize has each object and its object value of cohesion relation with pay invoice.In the present embodiment, order It is single inherently to polymerize example.Then, polyase 13 06, which receives, creates pay invoice order 302, performs order 302 and generates branch Pay order creation event 308.Pay invoice, which creates event 308, will be written into (namely the first database of event storage repository 314 110), by the persistence of event 308.

Polyase 13 06 performs pay invoice order 304 in response to receiving, and will pay request and transfers to Third-party payment channel 310 processing, pay invoice polyase 13 06 generates pay invoice and performs event 312 after third party is disposed.Here, it is all with ordering The related operation of order is all realized by event, thus can be remembered by record event to record the history run of processing system 102 Record, and can easily roll back to a certain historic state.These events such as pay invoice creates event 308, pay invoice Execution event 312 or other events will be all stored in event storage repository 314, and can be deposited in the form of flow of event 316 .Such as some order likely corresponds to multiple events, so as to produce flow of event；And on paying all events asked by shape Into complete flow of event.

Event is also published in event queue 318 simultaneously, to update inquiry client database i.e. data warehouse by event 320 (i.e. the second databases 112).Event queue 318 can be based on Ringbuffer structures, and the queue of such data structure provides Reliable message transmission characteristic.In addition, event queue 318 is responsible for each event passing to different consumers or event subscription Person, to realize the various functions such as the statistics of system, audit.

Fig. 4 shows the schematic diagram based on event driven Implement of Function Module 400 according to the embodiment of the present disclosure.Fig. 4 In show three functional module examples：Notification module 408, Audit Module 410 and statistical module 412.It is appreciated that these work( Energy module is only the example according to specific embodiment, can have multiple different functions according to the difference of application scenarios in system Module.Each functional module can subscribe to the event queue being each concerned about.

In the present embodiment, for example, pay invoice, which performs event 116, is distributed to event queue 318.Event queue 318 Can be based on Ringbuffer data structures as described above, be inserted by event and be managed with poller module 402.Three Functional module have subscribed pay invoice and performs event 116 respectively, and the event is the event object of amount of money involved transaction.When each function When module receives the event, notification module 404 is responsible for the implementing result of pay invoice returning to trade company；Audit Module 406 Record the execution data of order, there is provided core data is audited；The order of the record of statistical module 408 and statistical processing system 102 is whole Body state.As can be seen from Fig. 4, can not only be made between each functional module mutually solely based on event driven function module design Stand, do not interfere with each other, and the horizontal extension of performance can be accomplished well, i.e., when a certain functional module can not meet current business Amount access can be by adding more identical function processing module examples come answering pressure when needing.It is in addition, raw in event-driven Asynchronism be also solve systematic function bottleneck effective help.

As it was previously stated, embodiment of the disclosure can provide the replay to transaction business event, this is for improving and safeguarding The robustness of payment system is especially helpful.The reversibility of event and replay are that event of the embodiment of the disclosure based on CQRS is driven One of dynamic benefit of system architecture, it is solved well, and production problem can not be reappeared under legacy system framework and mistake is asked Topic is difficult the problem of investigation.As is described in connection with fig. 3, any operation based on pay invoice can all produce corresponding event simultaneously It is stored to flow of event warehouse, and processing system 102 can completely construct pair from scratch from a complete flow of event The polymerization answered, this suffers from huge side to the basic reason (either code logic or service logic) for finding Problem-Error Help.

Fig. 5 shows the event replay 500 according to one embodiment of the disclosure.For example, in the present embodiment, when When needing to replay pay invoice, 502, replay request is received, replay request includes it is expected that the pay invoice of replay corresponds to Polymerization and/or polymerize example identifier.In response to receiving replay request, 504, based on the identifier of polymerization example, Identify that pay invoice polymerize, judge that complete flow of event whether there is, if it does not exist, then determining not replaying simultaneously 510 Exit execution.If flow of event is present, each event in replay pay invoice polymerization 502, respectively in 512,514 and 516 weights Broadcast the order event of creating, replay execution of order event, replay order status event, and 518, obtain order end-state, it is complete Into replay.

The advantages of in order to further describe the embodiment of the present disclosure, Fig. 6 show the place of one embodiment according to the disclosure The schematic diagram 600 that reason system 102 interacts with third party system.In order to simplify description, being previously alluded in Fig. 6 Each part or module are not repeated to describe herein, while pay invoice processing module 602 for example can correspond to described in Fig. 3 Pay invoice processing procedure.As shown in fig. 6, processing system 102 includes tripartite's branch with the interactive examples of third party system Pay channel processing system 604, Outside Mail server 616, outside short message (SMS) server 618, archives economy 620 and pipe Manage banner system 622.Pay invoice processing module 602 is interacted to complete payment processes with tripartite's channel of disbursement processing system 604 Request；The notification module 610 of processing system 102 can notify trade company by modes such as mail or SMS using third party system Order implementing result；The Audit Module 612 of processing system 102 can be by performing the export of associative operation record or transmission by order To archives economy 620；Associated statistical information can be supplied to management banner system 622 by statistical module 614.As can be seen from Fig. 6, Needed when being handled except pay invoice and tripartite's payment system close coupling, other interactions for being related to three method, systems are all based on event Tupe, such system can not only completely cut off the close dependence to other three method, systems, can also dynamic add it is new Tripartite's interaction removes unnecessary tripartite's dependence, realizes the loose coupling of system to greatest extent.
