Paging scenarios can be seen everywhere, such as the dynamics loaded in WeChat Moments, the news loaded in the headlines every time, the details in the bank consumption records, etc.

[0003] The inventor found in the process of implementing the present invention that, in the web system with SSM (Spring MVC, Spring boot and Mybatis) as the architecture, the common practice is to use PageHelper plug-in, before calling data query at the application layer, first obtain paging parameters, then call paging operation, and finally perform business data query. These operations have nothing to do with business logic, but the same coding is required every time, so that the system is full of a large amount of redundant code, resulting in extremely low paging processing efficiency and very easy to make mistakes. In addition, a large amount of redundant code greatly reduces the readability and maintainability of the code, and also brings disaster to system maintenance. Summary of the invention

[0049] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing embodiments in an optional embodiment and are not intended to limit the present invention.

[0051] The paging processing method provided by the embodiment of the present invention is executed by an electronic device, and accordingly, the paging processing device runs in the electronic device.

[0052] Embodiment 1

[0053] Figure 1 This is a flow chart of a paging processing method provided by Embodiment 1 of the present invention. The paging processing method specifically includes the following steps. According to different requirements, the order of the steps in the flow chart can be changed, and some steps can be omitted.

[0054] S11, in response to an access request from a client, parsing the access request to obtain paging parameters.

[0055] The user may request access to data through the client's browser, for example, by inputting a page number in the client's browser to trigger an access request, thereby requesting access to data corresponding to the input page number.

[0056] The access request initiated by the client may be a GET request or a POST request. After receiving the access request from the client, the electronic device responds to the access request and parses the access request, thereby parsing the access request to obtain paging parameters.

[0057] The paging parameters refer to parameters for how to paginate the paging query results, and may include, but are not limited to: the number of paging pages (PageNo) and the paging size (PageSize). The paging size refers to the number of query data contained in each page.

[0058] In an optional implementation, parsing the access request to obtain the paging parameter includes:

[0059] Add Spring MVC filter based on Spring MVC framework;

[0060] Intercepting the access request by the Spring MVC filter;

[0061] The paging parameters are obtained by parsing the URL corresponding to the access request.

[0062] Spring MVC is a lightweight Web development framework based on the MVC design pattern provided by Spring, which is essentially equivalent to Servlet. Add OncePerRequestFilter in the Spring MVC framework as a Spring MVC filter.

[0063] After the access request is intercepted by the Spring MVC filter, the URL (Uniform Resource Locator) corresponding to the access request can be obtained, and then the paging parameters can be obtained by parsing the URL. When the access request is a GET request, the string corresponding to the URL can be parsed to obtain the paging parameters. When the access request is a POST request, the paging parameters can be obtained by parsing the request body of the POST request.

[0064] In an optional implementation, if the paging parameters cannot be obtained, the paging parameters are set to default values. Setting the paging parameters to default values ​​includes setting pageNo and pageSize to default values. For example, pageNo is set to 1 by default, and pageSize is set to 10 by default.

[0065] S12, storing the paging parameter in a local thread variable.

[0066] The paging parameters are stored in the local thread variables. In this way, there is no need to pass the paging parameters in the method call. In the subsequent paging operation, they can be taken out from the local thread variables at any time, which reduces the parameter passing process between methods and reduces the amount of code.

[0067] S13, determining whether the access request is a paging query request by using Java reflection technology.

[0068] First, determine which of the local thread variables are paging query requests, and after determining the paging query requests, call the paging operation.

[0069] In an optional implementation, the determining whether the access request is a paging query request by using Java reflection technology includes:

[0070] Add Mybatis interceptor;

[0071] Intercept the access request of each data layer through the Mybatis interceptor;

[0072] According to the calling method of the Dao layer for the access request, the return type of the calling method is obtained through Java reflection technology;

[0073] It is determined whether the access request is a paging query request according to the return type.

[0074] MyBatis is a persistence framework that supports customized SQL, stored procedures, and advanced mapping. MyBatis can use simple XML or annotations to configure and map native information, mapping interfaces and Java POJOs (Plain Ordinary Java Objects) into records in the database.

[0075] When each database query request reaches the data operation layer, the database query statement is written in the Dao layer. According to the calling method of the Dao layer, the return type of the calling method is obtained through Java reflection technology, so as to judge whether the access request is a paging query request based on the return type.

[0076] In an optional implementation, judging whether the access request is a paging query request according to the return type includes:

[0077] Determine whether the return type is a paging type;

[0078] If the return type is a paging type, determining that the access request is the paging query request;

[0079] If the return type is not a paging type, it is determined that the access request is not a paging query request.

[0080] If the return type is the paging type com.github.pagehelper.Page, it is determined that the access request is a paging query request.

[0081] If the return type is not the paging type com.github.pagehelper.Page, it is determined that the access request is not a paging query request.

[0082] S14, when it is determined through the Java reflection technology that the access request is the paging query request, obtaining a target paging parameter corresponding to the paging query request from the local thread variable.

[0083] If it is determined that the access request is a paging query request, the paging parameter is obtained from the local thread variable, and the paging code is inserted into the paging query request to call the paging operation.

[0084] If it is determined that the access request is not a paging query request, the access operation corresponding to the access request is executed and the access result is returned.

[0085] S15, returning paging query results according to the target paging parameters.

[0086] For the backend service system that uses MyBatis for database operations, it is inevitable to perform frequent query operations on the database. If all the data in the database is queried at once every time, the system performance will inevitably be greatly reduced. Especially for queries with a large amount of data, querying all the data at once will not only reduce system performance but also cause the system to crash. In this case, the paging query function is needed to query only part of the data at a time, which can not only improve system efficiency but also improve data utilization.

[0087] In an optional implementation, returning the paging query result according to the target paging parameter includes:

[0088] Get the specified page number in the target paging parameter;

[0089] Determine whether the specified page number is greater than the page number of the last page in the paginated query result;

[0090] If the specified page number is greater than the page number of the last page in the paginated query result, the data of the last page is returned;

[0091] If the specified page number is not greater than the page number of the last page in the paging query result, the data of the specified page number is returned.

[0092] In a scenario where multiple people are operating, it is easy for others to delete part of the data during the query, causing the page number being queried to exceed the maximum page number. In this embodiment, when the specified page number is greater than the last page during the paging query, the last page of data is queried. After this processing, the data cannot be found due to an error in the page number. The data cannot be found only when there is no data, thus avoiding the situation where the non-empty data query is empty.

[0093] In an optional implementation, after returning the data of the specified page number, the:

[0094] Obtaining the updated data of the specified page number and the paging identifier corresponding to the specified page number;

[0095] Storing the updated data of the specified page number in a local database;

[0096] Acquire the object corresponding to the updated data according to the paging identifier corresponding to the specified page number, search for other pages where the object is located, and acquire the corresponding paging identifiers of the other pages;

[0097] When the designated page number is closed, according to the page identifiers corresponding to the other pages, the refresh methods of the other pages are called to obtain the updated data from the local database and pass the updated data to the other pages;

[0098] Refresh the objects of the other pages according to the updated data to obtain the updated data of the other pages.

[0099] The designated page number refers to pageNo, and the paging identifier is used to distinguish different pages. In a specific implementation manner, the paging identifier is the URL of the page.

[0100] The refresh method can be "RefreshByRootPage()".

[0101] After the data of the specified page number is updated, it is saved in the database. In a specific application scenario, when the user updates the data of the specified page number and clicks Save, the updated data of the specified page number is stored in the database, and the paging identifier of the specified page number is obtained. The object is obtained according to the paging identifier of the specified page number, and the other pages where the object is located are found, and the paging identifiers of the other pages are obtained. At the same time, the specified page number is manually or automatically closed. According to the paging identifiers of other pages, the refresh method of other pages is called to refresh the objects of other pages from the database, thereby obtaining the refresh data of other pages, without waiting for the scheduled refresh or the user manually clicking refresh on other pages. When the user sees other pages, he can see the updated data of other pages that have been refreshed.

[0102] In the above optional implementation, by obtaining the updated data of the specified page number, finding the paging associated with the object according to the object of the specified page number and obtaining its paging identifier, calling the refresh method of the associated paging to refresh the associated paging, after the data of the specified page number is updated, the other associated paging can automatically and timely update the data without the need for manual refresh by the user.

[0103] In an optional embodiment, the method further comprises:

[0104] An array is created, wherein the array includes a plurality of structures, each of which includes a paging identifier and an object corresponding to the paging identifier.

[0105] A corresponding structure is established for the paging identifier and object of each page, that is, each structure includes two attributes, the paging identifier and the object.

[0106] In the above optional implementation, by establishing a structure including a paging identifier and an object, the object corresponding to the update data can be quickly obtained according to the paging identifier corresponding to the specified page number, so that the data can be quickly updated.

[0107] The paging processing method provided by the embodiment of the present invention, upon receiving an access request from a client, first obtains the paging parameters in the access request and passes the paging parameters through the local thread variables in the entire calling process, thereby solving the problem that developers need to manually parse the paging parameters and pass them as method parameters in the traditional paging method. Then, after determining that the access request is a paging query request through Java reflection technology, the target paging parameters corresponding to the paging query request are directly obtained from the local thread variables, the paging operation is called and the paging query results corresponding to the target paging parameters are returned, thereby solving the problem that developers need to manually call the paging operation in the traditional solution and improving the efficiency of paging processing. In addition, the backend developers no longer need to write paging codes that are not related to the business, which greatly reduces the amount of redundant code in the system template style, improves the readability of the code to a certain extent, and reduces the code compilation time. Less code means higher maintainability.

[0108] Embodiment 2

[0109] Figure 2 It is a structural diagram of a paging processing device provided in Embodiment 2 of the present invention.

[0110] In some embodiments, the paging processing device 20 may include a plurality of functional modules composed of computer program segments. The computer programs of the various program segments in the paging processing device 20 may be stored in a memory of an electronic device and executed by at least one processor to execute (see Figure 1 Description) Functionality for paging processing.

[0111] In this embodiment, the paging processing device 20 can be divided into multiple functional modules according to the functions it performs. The functional modules may include: a parsing module 201, a storage module 202, a judgment module 203, an acquisition module 204, a query module 205 and a refresh module 206.

When the access request is a GET request, the string corresponding to the URL can be parsed to obtain the paging parameters. When the access request is a POST request, the paging parameters can be obtained by parsing the request body of the POST request.

[0122] In an optional implementation, if the paging parameters cannot be obtained, the paging parameters are set to default values. Setting the paging parameters to default values ​​includes setting pageNo and pageSize to default values. For example, pageNo is set to 1 by default, and pageSize is set to 10 by default.

[0123] The storing module 202 is used to store the paging parameters into local thread variables.

[0124] The paging parameters are stored in the local thread variables. In this way, there is no need to pass the paging parameters in the method call. In the subsequent paging operation, they can be taken out from the local thread variables at any time, which reduces the parameter passing process between methods and reduces the amount of code.

[0125] The determination module 203 is used to determine whether the access request is a paging query request by using Java reflection technology.

[0126] First, determine which of the local thread variables are paging query requests, and after determining the paging query requests, call the paging operation.
