Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The POS settlement method based on AOP (Aspect organized Programming) provided in the embodiment of the present application may be applied to an application environment as shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store commodity inventory information and settlement information. The data storage system may be integrated on the server 104, or may be located on the cloud or other network server. The AOP is a section-oriented programming, and the coupling degree between service modules is reduced by introducing a public behavior to dispersed objects or services, so that each part of service logic can be isolated, the coupling degree between each part of the service logic is reduced, the reusability of a program is improved, and the efficiency of secondary development is improved. Specifically, in the present application, based on the idea of AOP, the exercise mode switch state data is introduced into the settlement information, and in the process of executing the POS settlement method by the terminal 102: acquiring settlement information required by bill receiving settlement; the settlement information comprises settlement data and exercise mode switch state data; extracting exercise mode switch state data in the settlement information, and judging whether the current exercise mode is in the exercise mode or not according to the exercise mode switch state data; if the user is not in the exercise mode, the steps of saving and uploading settlement data are executed, and a payment instruction is generated according to the settlement data; and if the current state is in the exercise mode, skipping the steps of saving and uploading settlement data, and generating a virtual payment instruction according to the settlement data. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices. The server 104 may be implemented as a stand-alone server or as a server cluster comprised of multiple servers.
In one embodiment, as shown in fig. 2, an AOP-based POS settlement method is provided, which is exemplified by the application of the method to the terminal 102. In this embodiment, the POS settlement method based on AOP includes steps S201 to S207.
In step S201, settlement information required for receipt settlement is acquired.
The settlement information includes settlement data and exercise mode switch state data. The settlement data specifically includes commodity sales information and customer information. The merchandise sales information includes, but is not limited to, a trade name, unit price, number of sales, time of sale, sales shop and cashier identification, etc. The customer information includes, but is not limited to, customer member account number and balance, etc. The exercise mode switch state data is state data for identifying whether the exercise mode is on.
It should be noted that, the client information (including but not limited to client device information, client personal information, etc.) and data (including but not limited to data for analysis, stored data, presented data, etc.) referred to in the present application are information and data authorized by the user or sufficiently authorized by each party.
Specifically, the terminal may directly acquire settlement information required for receipt settlement from the code scanning terminal or the server, or may acquire settlement data, and generate settlement information required for receipt settlement based on the settlement data and the exercise mode switch state data. Further, the specific manner of acquiring the settlement data by the terminal is not unique, for example, the settlement data can be acquired from a code scanning terminal in a code scanning manner; as shown in fig. 3, the product information may be displayed on the user interface, and the cashier may click on the corresponding product on the user interface to transmit the settlement data to the terminal. The commodity information may be displayed in a classified manner, for example, in fig. 3, the commodity is classified into categories such as food, daily commodities, fresh food, and the like, and then displayed in different categories. Further, a commodity search service can be provided so as to quickly acquire commodity information.
Step S203, extracting the exercise mode switch state data in the settlement information, and judging whether the current exercise mode is in the exercise mode according to the exercise mode switch state data.
As described above, the exercise mode switch state data is state data for identifying whether the exercise mode is on. Based on the above, the terminal can extract the exercise mode switch state data in the settlement information and judge whether the terminal is in the exercise mode at present according to the exercise mode switch state data. For example, when the value of the exercise mode switch state data is a preset value, it is determined that the exercise mode is currently in the practice mode, or when the data format of the exercise mode switch state data is a preset format, it is determined that the exercise mode is currently in the practice mode.
Further, after judging whether the current mode is the practice mode or not, a judgment result can be output, so that a cashier can conveniently confirm the current mode in real time. As in FIG. 3, the left window of the user interface displays the "exercise mode" script when currently in the exercise mode. Wherein, the word of the 'practice mode' can be set as the watermark to avoid influencing other display contents in the window.
In addition, the specific way of extracting the exercise mode switch state data in the settlement information by the terminal is not unique, and for example, the exercise mode switch state data can be obtained by extracting the storage information in the corresponding field according to the field of the exercise mode switch state data in the settlement information.
In one embodiment, extracting exercise mode switch state data in settlement information comprises: and extracting a base class used for storing the exercise mode switch state data in the settlement information, and determining the exercise mode switch state data according to the base class.
Wherein, the base class refers to a class type defined to contain all entity commonalities in object-oriented design. Specifically, each data entity of the settlement information inherits a base class for storing exercise mode switch state data, and during settlement, the exercise mode switch state data stored in the base class of the data entity is extracted, and whether the data entity is in the exercise mode at present is judged according to the exercise mode switch state data.
And S205, if the user is not in the exercise mode at present, executing the steps of saving and uploading settlement data, and generating a payment instruction according to the settlement data.
It can be understood that if the current state is not in the practice mode, the current state is in the ordinary settlement state, the normal settlement step can be performed, the step of saving and uploading the settlement data is executed, and the payment instruction is generated according to the settlement data. The payment instruction is used for instructing a user to pay, and fund transfer occurs in the payment process. Further, the payment method includes mobile payment, cash payment or member deduction, and correspondingly, as shown in fig. 3, different areas on the user interface may be clicked according to different payment methods to perform settlement.
And step S207, if the user is in the exercise mode, skipping the step of saving and uploading settlement data, and generating a virtual payment instruction according to the settlement data.
If the payment terminal is in the exercise mode, the payment terminal is in the cash register exercise state, the settlement data does not need to be stored and uploaded, at the moment, the terminal skips the step of storing and uploading the settlement data, and a virtual payment instruction is directly generated according to the settlement data. Wherein the virtual payment instruction is used for instructing the user to make a virtual payment. In the virtual payment process, only payment actions are performed without actually transferring funds. In the practice mode, the cashier can simulate the user to make virtual payment in various ways, such as clicking a virtual payment completion option or scanning a two-dimensional code for virtual payment.
The POS settlement method based on the AOP adopts the design idea of section-oriented programming to isolate all parts of the business logic, so that the coupling degree between all parts of the business logic is reduced. On one hand, on the premise of not influencing system data, the training requirement on a new cashier can be met, and the expansion of the application scene of the POS settlement method is facilitated; on the other hand, due to the low coupling degree among all the parts of the business logic, the reusability of the program is improved, the efficiency of secondary development is further improved, and the development cost is reduced.
In one embodiment, as shown in fig. 4, acquiring settlement information required for settlement of a receipt includes step S402 and step S404.
Step S402, obtaining a key value pair used for identifying the state of the exercise mode switch in the xml file, and determining exercise mode switch state data according to the key value pair.
The xml is an EXtensible Markup Language (xml) used for marking electronic documents to have structure. An xml file is an xml-based data storage file. The xml file can be stored in a data storage module of the terminal or an external data storage system. In short, the present embodiment does not limit the specific storage location of the xml file. The key is located at the end of the chain of registry structures and, like the files of the file system, contains the actual configuration information and data used when the computer and application programs are currently executing.
Specifically, the exercise mode switch state data is stored in an xml file in a key value pair mode through the SharePreference, and the terminal determines the exercise mode switch state data by obtaining the key value pair used for identifying the exercise mode switch state in the xml file.
Step S404, acquiring settlement data, and generating settlement information required by the receipt settlement calculation based on the settlement data and the exercise mode switch state data.
For the manner of acquiring the settlement data, reference is made above, and details are not repeated here. Specifically, the terminal acquires settlement data and generates settlement information required for receipt calculation based on the settlement data and exercise mode switch state data according to a preset data arrangement mode and a preset data format.
In the embodiment, the exercise mode switch state data is stored in the xml file in a key-value pair mode through the SharePreference, on one hand, depending on the data persistence characteristic of the SharePreference, the exercise mode switch state cannot fail due to the restart of the app, and the use convenience is improved; on the other hand, the settlement system can be more light-weight, and data can be cleared at the same time during uninstallation without causing data residue.
In an embodiment, with continuing reference to fig. 4, before step S402, step S401 is further included: and acquiring an exercise mode starting instruction, and correspondingly updating the key value pair used for identifying the exercise mode switch state in the xml file according to the exercise mode starting instruction.
The method for the terminal to obtain the exercise mode starting instruction is not unique. As shown in fig. 5, the cashier may click on the "exercise mode" in the function menu interface and send an exercise mode start instruction to the terminal; the terminal can also automatically start the exercise mode to obtain an exercise mode starting instruction when the exercise duration is lower than the preset duration according to the exercise duration of the cashier corresponding to the cashier identification in the settlement information.
Specifically, the terminal acquires an exercise mode starting instruction, checks a key value pair used for identifying the exercise mode switch state in the xml file according to the exercise mode starting instruction, keeps the key value pair unchanged if the key value pair is consistent, and correspondingly updates the key value pair used for identifying the exercise mode switch state in the xml file if the key value pair is inconsistent.
Further, as shown in fig. 5, the POS system also supports various functions such as goods management, member management, statistics management, and sales management. The goods management comprises goods returning, goods changing, goods taking, goods delivery, stock inquiry, goods delivery bin switching and the like; member management includes newly added members, etc.; the statistical management comprises store collection and payment condition statistics, order management, shift knots, day knots and the like; sales management includes sales documents, business documents, and the like. And a message center is arranged to support various operations such as manual data synchronization, off-line work and the like.
In the above embodiment, before the terminal extracts the exercise mode switch state data, the exercise mode start instruction is acquired, and the key value pair for identifying the exercise mode switch state in the xml file is updated according to the exercise mode start instruction, so that the extracted exercise mode switch state data can be ensured to be the latest data, and the accuracy of the exercise mode switch state data can be improved.
In one embodiment, as shown in fig. 6, after step S207, step S208 is further included: and receiving the virtual payment feedback information, and outputting prompt information according to the virtual payment feedback information.
The virtual payment feedback information refers to feedback information received by the terminal after the user performs virtual payment. The virtual payment feedback information may specifically include a payment amount, a payment channel, and the like. Specifically, the terminal may output corresponding prompt information according to the virtual payment feedback information: as shown in fig. 7, when the payment amount is larger than the settlement amount, the change giving prompt information is output; when the code scanning payment is successful or the change is completed, payment completion information is output; and when the code scanning payment fails, outputting payment failure information. Further, when the prompt message is the payment completion message, the sales page can be automatically returned to perform the next settlement.
In one embodiment, the prompt message includes payment completion information, please continue to refer to fig. 6, in this embodiment, after step S208, step S209 is further included: and generating a business document printing instruction according to the prompt information, and indicating a printer to print the business document.
The specific content of the business document includes, but is not limited to, commodity sales information and customer information.
Further, when the mobile terminal is not in the practice mode at present, after the payment instruction is generated, the payment feedback information can be received, the corresponding prompt information is output according to the payment feedback information, and when the prompt information is payment completion information, a business document printing instruction is generated to instruct the printer to print the business document.
In the above embodiment, in practice mode, the settlement process simulation of the whole process is provided, so that a new cashier can be helped to quickly learn the whole settlement process, and the learning effect is improved.
For the sake of understanding, the AOP-based POS settlement method in the present application will be described in detail below with reference to fig. 8 and 9.
In the embodiment, under the software architecture of the android system, exercise mode switch state data is stored in an xml file in a key-value pair form through the SharePreference, wherein a default value of the exercise mode switch state data is a non-exercise mode. By virtue of the data persistence feature of SharePresence, exercise mode switch state data is not invalidated by a restart of a settlement system application (app). When the cashier starts the exercise mode at the app function menu page, the program will update the key-value pairs stored in the xml file to the exercise mode state.
Furthermore, the practice mode is not required to generate any data, which is mainly based on the idea of AOP, and common behaviors are introduced for dispersed objects or services, so that the coupling degree between service modules is reduced, and the later maintenance is easier. Specifically, according to the application, since the uploading data relates to interface calling, and the data entities transmitted by each interface are different, each settlement information data entity inherits a base class base request for storing the state of the exercise mode switch. Before uploading the data, taking out the exercise mode switch state data in the settlement information, and judging whether the current exercise mode is in the exercise mode according to the exercise mode switch state data. If the User is in the practice mode, the steps of storing and uploading data are skipped, the Interface calling successful logic in the common settlement mode is directly executed to interact with a User Interface (UI), for example, the sale completion prompt indicates that payment is successful, the page automatically returns to the sale page, and the printing of the business document is carried out.
It can be understood that if the current state is in a common settlement state, normal settlement steps are performed, the steps of saving and uploading settlement data are executed, the local database is updated, and a payment instruction is generated according to the settlement data to instruct the user to pay. And receiving payment feedback information, outputting corresponding prompt information according to the payment feedback information, and generating a business document printing instruction to instruct a printer to print the business document when the prompt information is payment completion information.
According to the POS settlement method based on the AOP, data is not stored and uploaded in the practice mode, and a new cashier can use various functions of the system at will under the condition that the new cashier is not familiar with software, so that on one hand, the training requirement on the new cashier can be met on the premise that system data is not influenced, and the application scene of the POS settlement method can be expanded; on the other hand, due to the low coupling degree among all the parts of the business logic, the reusability of the program is improved, the efficiency of secondary development is further improved, and the development cost is reduced.
It should be understood that, although the steps in the flowcharts related to the embodiments as described above are sequentially displayed as indicated by arrows, the steps are not necessarily performed sequentially as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
