It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It should be noted that although functional blocks are partitioned in a schematic diagram of an apparatus and a logical order is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the partitioning of blocks in the apparatus or the order in the flowchart. The terms first, second and the like in the description and in the claims, and the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

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 is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

First, several terms referred to in the present application are resolved:

structured Query Language (SQL): is a standard computer language for accessing and processing databases and is used for managing a relational database management system, including data insertion, query, update and deletion, database schema creation and modification, data access control and the like. The same structured query language can be used as an interface for data entry and management, even for database systems of different underlying structures.

SSM framework layering (Spring + SpringMVC + MyBatis): including a Dao layer, a Service layer, a Controller layer (Handler layer), and a View layer. The data processing method comprises the following steps that a Dao layer is used for processing data services according to a calling interface, wherein parameters related to database connection are all configured and realized in a data source of the Dao layer; and the Service layer is used for carrying out corresponding logic application design according to the Service requirement. The Dao layer and the Service layer are independent from each other and can be designed in a split mode, and the Controller layer (Handler layer) and the View layer are mainly responsible for controlling specific business processes and displaying effects of foreground pages and generally need to be designed in a combined mode.

Redis caching: the remote Dictionary service (Redis) is an open source, written by using ANSI C language, supporting network, a log-type and Key-Value database which can be based on memory and can also be persistent, and provides API Redis of multiple languages as a Key-Value storage system, and the Value types supported for storage comprise string, list, set, zset and hash. These data types all support push/pop, add/remove, and intersect union and difference, and richer operations, and these operations are all atomic. On this basis, Redis supports various different ways of ordering. As with memcached, data is cached in memory to ensure efficiency. The difference is that Redis periodically writes updated data to a disk or writes a modification operation to an additional recording file, and a master-slave synchronization is realized on the basis of the updated data or the modification operation.

Jvm cache: JVM is an abbreviation for Java Virtual Machine, which is essentially a piece of software. The JVM is a specification for a computing device, which is an imaginary computer implemented by emulating and simulating various computer functions on an actual computer.

MD 5: a widely used cryptographic hash function generates a 128-bit (16-byte) hash value to ensure the integrity of the message transmission. The method has the characteristics of universality, stability and quickness, and is applied to the field of encryption protection of common data.

AOP: AOP is an abbreviation for Aspect organized Programming, meaning: the method is a technique for realizing the unified maintenance of the program functions by a precompilation mode and a dynamic proxy during the running process in the aspect-oriented programming. The AOP is a continuation of the OOP, is a hot spot in software development, is also an important content in a Spring framework, and is a derivative paradigm of functional programming. By utilizing the AOP, all parts of the business logic can be isolated, so that the coupling degree between all parts of the business logic is reduced, the reusability of a program is improved, and the development efficiency is improved.

Spring: the Spring framework is an open source J2EE application framework, and is a lightweight container (light container) for managing the lifecycle of beans. The Spring framework mainly comprises seven parts, namely Spring Core, Spring AOP, Spring ORM, Spring DAO, Spring context Spring Web and Spring Web MVC. Spring provides functions such as powerful IOC, AOP, Web MVC and the like, can be independently applied to construction of application programs, can be combined with a plurality of Web frameworks such as Struts, Webwork, Tapestry and the like, and can be combined with desktop application programs such as Swing and the like, namely AP.

Fig. 1 is an optional flowchart of a data call method provided in an embodiment of the present application, where the method in fig. 1 may include, but is not limited to, steps S100 to S600.

Step S100, obtaining a data calling request from a service layer;

step S200, analyzing the data call request to obtain target interface information, and screening the interface of a pre-constructed target cache layer according to the target interface information to obtain a target cache interface;

step S300, performing data query on the target cache layer according to a target cache interface to obtain a query result; the query result comprises a first result that the target cache layer has cache data or a second result that the target cache layer does not have cache data;

step S500, generating target data according to the initial cache data or the initial storage data;

in step S600, target data is called.

In steps S100 to S600 illustrated in the embodiment of the present application, the data call request is obtained through the acquisition service layer. Specifically, the method and the device can obtain query requests corresponding to all data required to be queried by a user through a service layer, and summarize all the requests to obtain a data call request corresponding to call of each data; the target cache interface is obtained by analyzing the data calling request, and the interface of the pre-constructed target cache layer is screened according to the target interface information, so that the target cache interface is obtained; the method comprises the steps that data query is carried out on a target cache layer according to a target cache interface to obtain a query result, communication connection is established between the target cache interface and the target cache layer, so that traversal query is carried out on data stored in the target cache layer, and a corresponding query result is obtained, wherein the query result comprises a first result that cache data exist in the target cache layer or a second result that cache data do not exist in the target cache layer, and initial data are called from different storage areas according to different obtained query results; the initial data may be initial cache data or initial storage data. Specifically, according to a first result, extracting initial cache data from a target cache layer, or according to a second result, extracting initial storage data from a preset data access layer; the target cache layer is positioned between the service layer and the data access layer; finally, target data are generated according to the initial cache data or the initial storage data; specifically, when the application acquires initial cache data, the initial cache data is used as target data, or when the application acquires initial storage data, the initial storage data is used as target data. It should be noted that the method can only obtain one of the initial storage data or the initial cache data. When the initial cache data or the initial storage data is acquired at the same time, the method re-executes step S300 to determine the storage state of the cache data in the target cache layer, so as to acquire the initial cache data or the initial storage data. By the method, the application provides a new query mechanism, namely, the data in the target cache layer is queried by acquiring a data call request from a service layer and communicating with the target cache layer through an interface, a first result is output when the cache data is stored in the target cache layer, and initial cache data is directly called from the target cache layer according to the first result to obtain the target data; or when the cache data is not stored in the query target cache layer, the data access layer is accessed through the target cache layer to realize the calling of the initial storage data so as to obtain the target data. The method and the device have the advantages that the access process can be more concise, frequent reading and calling of the data access layer are avoided, and the method and the device can effectively improve the stability of the system.

Referring to fig. 2, in some embodiments, step S200 may include, but is not limited to including, step S210 and step S230:

step S210, acquiring a target data table field of a target cache layer;

step S220, acquiring a reference field according to the target interface information;

and step S220, screening the candidate buffer interfaces of the target buffer layer according to the data table field and the reference field to obtain the target buffer interface.

In step S210 of some embodiments, a preset target cache layer is provided with a corresponding target data table field, and the target data table field depends on a tangent plane added by an AOP mechanism, and is matched with a preset reference field according to the target data table field of the preset target cache layer, so as to achieve acquisition of a target cache interface.

In step S230 of some embodiments, the target interface information includes a reference field of the target cache interface in communication connection with the target cache layer. The reference field can be used as an identity of the target cache interface, so that all available interfaces of the target cache layer are screened through the reference field to obtain the target cache interface.

In step S230 of some embodiments, the method provided by the present application performs matching analysis on the acquired data table field and a preset reference field to obtain association degree data of the data table field and the reference field, and filters all association degree data obtained through the matching analysis according to a preset association degree matching threshold to obtain a target cache interface corresponding to the association degree data meeting the matching requirement limited by the association degree matching threshold. In some specific embodiments, the method can also capture the data table fields of the target cache interfaces obtained through screening, and summarize the captured data table fields into the interface information directory to simplify the subsequent repeated calling process of the data.

Referring to fig. 3, in some embodiments, before step S300, the method further includes: constructing a target cache layer, specifically including but not limited to including steps S310 to S330:

step S310, traversing the data access layer, and inquiring the initial cache layer to obtain a first mapping relation between the data access layer and the initial cache layer;

step S320, acquiring a first dependency relationship between the service layer and the data access layer;

and step S330, converting the first dependency relationship according to the first mapping relationship to obtain a second dependency relationship between the service layer and the initial cache layer, and generating a target cache layer according to the second dependency relationship.

In step S310 of some embodiments, the present application traverses the data access layer in advance, and correspondingly queries a communication connection relationship between the initial cache layer and the data access layer according to a traversal result, so as to obtain a first mapping relationship including a communication connection line between the data access layer and the initial cache layer;

in step S320 in some embodiments, the application may obtain a communication relationship between the service layer and the data access layer, and obtain a corresponding first dependency relationship; through the first dependency relationship, the service layer can directly call the data stored in the data access layer according to the query request, but the service layer does not screen the data required to be queried by each query request. For the same query request, the service layer will perform repeated query actions, so as to make repeated calls for the same data.

In step S330 of some embodiments, the present application readjusts the dependency relationship among the service layer, the initial cache layer, and the data access layer, so that the method changes the dependency relationship among the service layer, the initial cache layer, and the data access layer into a second dependency relationship according to the first dependency relationship and the first mapping relationship, and redefines the attribute of the initial cache layer according to the second dependency relationship, thereby generating a target cache layer; through the second dependency relationship, the method realizes the access paths from the service layer to the target cache layer and from the target cache layer to the data access layer, and further realizes the caching of the call data through the target cache layer and the communication path for accessing the data access layer through the target cache layer.

In some specific embodiments, the method first scans an initial cache layer appointed for use to obtain an initial cache interface file of the initial cache layer, and records an association relation corresponding to a data access layer which is in communication connection with the initial cache interface file; the method also comprises the steps of traversing an available initial cache layer of the data access layer, resetting the initial dependency relationship from the service layer to the data access layer through a reflection mechanism, updating the dependency relationship of the data access layer, converting the initial cache layer to the target cache layer according to the updated dependency relationship, changing the dependency relationship of the service layer from the initial service layer to the data access layer into the dependency relationship from the service layer to the target cache layer to the data access layer, and calling the data through the target cache layer.

In some other embodiments, the conversion of the initial cache layer into the target cache layer according to the dependency relationship needs to be completed before the service layer dependency relationship is changed, so as to ensure that the service layer dependency relationship can be stably changed.

Referring to fig. 4, in some embodiments, step S400 includes, but is not limited to, steps S410 to S420:

step S410, if the target data table field corresponding to the target cache interface is in a complete non-empty state, a first cache key is constructed according to the target data table field;

step S420, performing data query according to the first cache key to obtain a first query result, and extracting initial cache data from the target cache layer according to the first query result; or, performing data query according to the first cache key to obtain a second query result, and extracting initial storage data from a preset data access layer according to the second query result.

In step S410 of some embodiments, the present application provides a method for establishing a target cache interface corresponding to a target cache layer to be accessed according to a target data table field, and generates a first cache key between the target cache layers to be accessed by detecting whether the target data table field is in a complete non-empty state.

In step S420 of some embodiments, the present application performs data query on a data storage state in the target cache layer according to the first cache key, and outputs a first query result when the data corresponding to the data call request is stored in the target cache layer, so as to extract initial cache data corresponding to the data call request from the target cache layer according to the first query result. Or after the data calling method provided by the application realizes the communication connection with the target cache layer through the first cache key, the method can inquire the storage state of the initial cache data corresponding to the data calling request in the target cache layer, and output the second inquiry result when detecting that the initial cache data is not stored in the target cache layer, so as to perform communication interaction with the data access layer according to the second inquiry result, and realize calling the initial storage data stored in the data access layer.

In some specific embodiments, the data call method provided by the present application may construct the access key according to the data state of the target data table field, and specifically, the method may read the data state of the target data table field corresponding to the target cache interface when communicating with any available target cache interface of the target cache layer. When the parameter information in the field of the target data table meets the complete non-empty state, the method can extract the parameter information in the field of the target data table and directly generate a corresponding first cache key according to the parameter information. Through the first cache key, the method can be connected with the specified target cache interface in a matching mode, and therefore data access and call of the target cache interface are achieved. When detecting that the initial cache data are stored in the target cache layer, generating a first query result representing that the calling data corresponding to the data calling request are stored in the target cache layer, and calling the target cache data by the control system according to the first query result, thereby realizing the calling of the data; or when detecting that the initial cache data is not stored in the target cache layer, generating a second query result representing that the target cache layer does not store the call data corresponding to the data call request, and controlling the system to access the data access layer according to the second query result, so as to query the target storage data and call the target storage data in the data access layer, thereby realizing the call of the data.

In some other embodiments, the data calling method provided by the application may further start a data capture process after the second query result is obtained. Specifically, when the second query result is detected, the called target storage data is captured, and a target data table field corresponding to the first cache key is obtained. According to the field of the target data table, the method can position the target cache interface used in the data calling process, and the captured target storage data is transferred to the target cache layer as the target cache data corresponding to the data calling request. By the method, SQL IO requests between the target cache layer and the data access layer can be avoided in the next data calling process, the target cache data transferred into the target cache layer can be directly called, the data query frequency is reduced, and the system load during data calling is effectively reduced.

Referring to fig. 5, in some embodiments, step S400 further includes, but is not limited to, steps S430 to S440:

step S430, if the target data table field corresponding to the target cache interface is in a complete non-empty state, constructing a second cache key according to the interface information of the data access layer;

step S440, performing data query according to the second cache key to obtain a third query result, and extracting initial cache data from the target cache layer according to the third query result; or, performing data query according to the second cache key to obtain a fourth query result, and extracting initial storage data from a preset data access layer according to the fourth query result.

In step S430 of some embodiments, the data state of the target data table field corresponding to the target cache interface is detected, and when the parameter information in the target data table field is in a complete non-empty state, the method may further construct a second cache key according to the target data table field and according to a preset construction rule.

In step S440 of some embodiments, the present application may make a call to data in the target cache layer according to the second cache key. When detecting that initial cache data corresponding to the data calling request is stored in the target cache layer, obtaining a third query result; and extracting initial cache data stored in the target cache layer according to the third query result. Or when detecting that the initial cache data corresponding to the data calling request is not stored in the target cache layer, obtaining a fourth query result; and accessing the data access layer through the target cache layer according to the fourth query result, and calling the initial village coarse data stored in the data access layer to obtain initial storage data.

In some specific embodiments, the application intercepts the interface information of the data access layer by using the Spring AOP technology, so as to prevent the target cache layer from directly calling the data access layer, thereby improving the security of the data calling process. Specifically, after intercepting the interface reference of the target cache layer to the data access layer, the method performs encryption processing according to the target data table field corresponding to the target cache interface and the limited name of the interface to obtain a second cache key, and queries the initial cache data in the target cache layer through the second cache key. When the initial cache data stored in the target cache layer is queried, the method can output a third query result and call the initial cache data; or, when it is queried that the initial cache data is not stored in the target cache layer, the method may output a fourth query result, and access the data access layer through the target cache layer according to the fourth query result, thereby invoking the target storage data stored in the data access layer.

In some other embodiments, the target cache layer provided by the present application provides different cache designs according to different cache media. The data calling method provided by the application can be applied to Redis cache. When the method is applied to Redis cache, each object in the table is designed to be a Hash structure object of Redis, and keys of target storage data corresponding to each Hash structure object are stored one by one. That is, the key corresponding to each hash object corresponds to one piece of target cache data. When the target cache data needs to be called, the method accesses by acquiring the key in the field of the target data table to obtain the corresponding target cache data.

In some other embodiments, the target cache layer provided by the present application provides different cache designs according to different cache media.

In steps S431 to S434 of some embodiments, the present application extracts parameter information of a target cache interface in which a target data table field is in a non-empty state, obtains first entry information and second entry information, encrypts the first entry information to obtain a first entry ciphertext, and encrypts the second entry information to obtain a second entry ciphertext; through the first parameter-entering ciphertext and the second parameter-entering ciphertext, the method can construct a second cache key, and further query and call the storage state of the target cache data in the target cache layer through the second cache key, or access the data access layer through the target cache layer through the second cache key, and call the target storage data stored in the data access layer. By the method, the access security of accessing the target cache layer through the second cache key is effectively guaranteed, and the security of the data calling method provided by the application is improved.

In some specific embodiments, the data calling method provided by the present application uses a Spring AOP technology to intercept an interface of a data access layer, and instead, realizes communication connection between a target cache layer and the data access layer through a second key. Specifically, the method can obtain the full qualified name of the target cache interface, and encrypt the full qualified name of the target cache interface as the first parameter entering information to obtain the first parameter entering ciphertext. The method can also acquire the actual parameter entering information of the target cache interface, and splice the acquiring sequence of the actual parameter entering information into a character string file as second parameter entering information, so as to obtain a second parameter entering ciphertext by encrypting the second parameter entering information. In some embodiments, the encryption method employs MD5 as an encryption means to achieve encryption of the incoming reference information. And a second cache key generated by encrypting with an MD5 encryption method is obtained by splicing the obtained first parameter-entering ciphertext and the second parameter-entering ciphertext, so that target cache data stored in cache media such as Redis and Jvm are queried and called through the second cache key, and the security of the data calling method provided by the application is improved.

In some other embodiments, when the cache medium corresponding to the target cache layer is queried through the second key and the corresponding target cache file is stored therein, the method may directly call and return the queried target cache file to the service layer to output the call file; and the service layer is prevented from carrying out SQL IO request on the data access layer through the target cache layer, so that the system load is reduced, and the calling efficiency of the data calling method is improved.

Referring to fig. 7, in some embodiments, after step S100 and before step S200, the data calling method includes, but is not limited to, steps S700 to S800:

step S700, monitoring the working state of a target cache layer according to a data calling request to obtain initial monitoring data;

step S800, format conversion is carried out on the initial monitoring data to obtain a target monitoring file, and the target monitoring file is used for optimizing a target cache layer.

In step S700 of some embodiments, the present application may establish a monitoring mechanism according to the data call request. Specifically, the method monitors real-time information such as interface calling start time, end time, interface cache use condition, interface name, access parameter information, actual access parameter information, dynamic information and the like of a data access layer by taking an interface as a unit aiming at statistics of an SQL (structured query language) level to obtain initial monitoring data. The initial monitoring data is stored in the memory by taking the interface as a unit so as to provide a calling basis of the initial monitoring data.

In step S800 in some embodiments, the method and the device may analyze the system characteristics represented by the initial monitoring data to be called, perform format conversion on the data representing the working state of the data access layer included in the system characteristics to obtain a target monitoring file, feed back the target monitoring file to the current data calling system, and optimize the calling accuracy and calling efficiency of the target cache layer in the data caching and data calling processes.

In some specific embodiments, the data calling method provided by the application uses a Spring AOP mechanism to monitor an interface of a data access layer accessed through a target cache layer, and encapsulates real-time information such as interface calling start time, end time, interface cache use condition, interface name, access information, actual access information, dynamic information and the like obtained in the monitoring process into counter objects uniformly according to the obtained interface units as units, so that each interface corresponds to a counter object corresponding to initial monitoring data. The method also provides an additional interface for triggering the initial monitoring data in the counter object format corresponding to each interface in the monitoring process, and outputting the triggered initial monitoring data in the Json format to form a target monitoring file. Therefore, the current working state between the target cache layer and the data access layer is fed back in real time, and the design optimization of the target cache layer is further realized.
