Description of the drawings
Fig. 1 is a kind of flow chart for cash register information synchronization method that embodiment of the present invention provides.
Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
It is a kind of flow chart for cash register information synchronization method that embodiment of the present invention provides, this method referring to Fig. 1, Fig. 1
Including：
Step S1：Server-side establishes corresponding first message queue to each cashier；
For example, the first message queue can be RabbitMQ queues；
Step S2：For each cashier, according to the user after receiving cash register operation information input by user
The cash register operation information update of the input local data base of itself, and the cash register operation information input by user is sent to institute
State server-side；
For example, above-mentioned cash register operation information can be to operation informations such as the increases, deletion, modification of cash register information；
Step S3：The receipts that the server-side is sent after the cash register operation information for receiving cashier transmission according to cashier
Silver-colored operation information update service client database, and cash register operation information storage that cashier is sent described first is disappeared in each
Cease queue；
Step S4：For first message queue described in each, the server-side is according to preset order by cash register therein
Operation information is sent to corresponding cashier；
For example, for each first message queue, server-side can be incited somebody to action according to the time for receiving cash register operation information
Cash register operation information in first message queue is sent to cashier, i.e., the cash register operation information first received is first sent, and is followed by
It is sent after the cash register operation information received；
In addition, when sending cash register operation information, server-side can also will send the cashier of the cash register operation information
Identity information is sent to cashier, and whether the cash register operation information to make cashier may determine that receive is what itself sent
Cash register operation information；
Wherein, for each first message queue, if server-side detection is when the preceding cash register operation letter sent to cashier
Breath is sent successfully, then is removed the currently transmitted successful cash register operation information from the first message queue, if detection is sent
The cash register operation information of the currently transmitted failure is then moved to the end of the first message queue by failure, is waited for and being retransmitted；
Step S5：The cash register operation information update local of itself that each described cashier is sent according to the server-side
Database；
Specifically, each cashier is first determined whether to connect after receiving the cash register operation information of server-side transmission
Whether the cash register operation information of receipts is the cash register operation information of itself transmission, if so, ignore the cash register operation information, if it is not,
Data update is then carried out to the local data base of cashier itself according to the cash register operation information；
The cash register information synchronization method that embodiment of the present invention provides, each cashier is by cash register operation information input by user
It is sent to server-side, server-side utilizes the first message by establishing corresponding first message queue to each cashier
Cash register operation information is sent to each cashier by queue, to realize the synchronization of data, can effectively be reduced compared with prior art
Delay improves the performance that data synchronize, realizes the Fast synchronization of multiple databases.
Preferably, in step s 2, each cashier may be used message queue and believe cash register operation input by user
Breath is sent to server-side, i.e., cash register operation information input by user is sent to the clothes by each cashier using following methods
Business end：
The cash register operation information storage input by user that each cashier receives itself is in second itself established
Message queue, for example, the second message queue can be RabbitMQ queues；
Each cashier sends the cash register operation information in the second message queue itself established according to preset order
To the server-side.
Cash register operation information input by user is sent to by the second message queue that each cashier is established using itself
Server-side specifically for each cashier, updates itself first after receiving cash register operation information input by user
Local data base, and store it in second message queue, wherein cashier inputs cash register operation information according to user
Cash register operation information in first message queue is sent to cashier by the time, i.e., the cash register operation information that user first inputs first is sent out
It send, is sent after the cash register operation information inputted after user；
It, will if cashier detection is sent successfully when the preceding cash register operation information sent to server-side in transmission process
The currently transmitted successful cash register operation information is removed from the second message queue, if detection sends failure, this is current
The cash register operation information for sending failure moves to the end of the second message queue, waits for and retransmitting.
The cash register information synchronization method that embodiment of the present invention provides carries out data synchronization, energy by using message queue
It enough realizes low latency transmission data library object, and realizes Object Persistence, ensure the consistency of synchronous reliability and data,
It is particularly suitable for the synchronization of multinode, mass data.
In addition, embodiment of the present invention additionally provides a kind of cash register system, including server-side and multiple cashiers；
Wherein, the server-side includes establishing module, the first update module, the first sending module and processing module；
The module of establishing to each cashier for establishing corresponding first message queue；
First update module is used to be sent according to cashier after the cash register operation information for receiving cashier transmission
Cash register operation information update service client database；
The cash register operation information storage that the processing module is used to send cashier is in each first message team
Row；
First sending module is used for for first message queue described in each, according to preset order by receipts therein
Silver-colored operation information is sent to corresponding cashier；
Each described cashier includes the second update module, the second sending module and third update module；
