Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the present invention, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

From the above background, J2 EE: the Java platform is designed for a large enterprise host level computing type, and is an enterprise version of Java for enterprise level application service development. In addition, currently, for J2EE Web application development based on Spring, a server adopts a traditional four-layer design structure model of 'a service layer + an application logic layer + a data access layer + a domain model layer'. In a traditional four-layer design structure model, a code developed by a developer is required to meet the design specification of each layer, and development technicians are required to have the capability of reasonably decomposing a service into each layer, so that the development capability of the developer is higher, and in a large-scale team and large-scale software development scene, at least 4 files corresponding to a service layer, an application logic layer, a data access layer and a field model layer are required for one service, a large number of code files are generated, so that the problems of complicated application development process and large code redundancy are caused.

Therefore, the embodiment of the invention provides a new development platform, and from the original realization of the 4-class object of the service layer, the application logic layer, the data access layer and the field model layer to the realization of the 2-class object of the service-to-component, the development structure is simple, so that the development requirement can be greatly reduced, the development code amount can be reduced, and the development efficiency can be further improved.

The development platform provided by the invention comprises two layers of target frameworks, specifically: the service layer and the component layer can perform data transfer between the service layer and the component layer through a simple Java Object (POJO) or a Java basic data type. In order to better understand the target architecture related to the embodiments of the present invention described below, the following detailed explanation is provided.

It should be noted that the service layer and the component layer respectively need to meet certain forms and specifications in organization, structure and implementation, and the details are as follows:

and (3) a service layer: used for providing services for the outside and bearing part of business logic. In the implementation aspect, the service layer provides a basic service function and externally exposes an interface called by the service; structurally, top-level interfaces of all service classes are IService interfaces, and the IService interfaces and all extended service classes are realized by inheriting a service class abstract parent class CnfAppService; in organization, all service classes are under the appservice package.

Assembly layer: for providing core resource services to the service layer. The component layer comprises a database component and a business function component, wherein the database component is used for accessing the database, and the business function component is used for realizing the business logic function of the service. In terms of implementation, the component layer is a single functional body and can only perform special processing on corresponding resources; structurally, the component layer comprises an ICnfComponent interface and a shared component type interface, the top layer interfaces of all the component types are the ICnfComponent interface, the ICnfComponent interface and the CnfComponent of the component type abstract parent class are inherited by the realization of all the component types, and a plurality of modules can call an identification component through the shared component type interface to be used as a special case for breaking through isolation control; in organization, all component classes are under the cmpt package, and the top layer is the componengt package.

It should be noted that, in implementation, a component class only provides services for a service class, and an instance object of the service class may hold one or more component class instances.

Furthermore, it should be noted that the unified agreement should be made on the directory structure of the project, i.e., the directory structure of the application, the directory names of the service layer and the component layer, and the names of the service class and the component class. The service layer under one module can not call the non-shared components of other modules, the service layer can not call the service layer, the component layer can not call the service layer, and the components in the component layer can not call the non-shared components of other services.

POJO class object: for passing data between the service layer and the component layer. The POJO class objects are organized, all the POJO classes are placed under the POJO package, and the POJO package is parallel to the appservice package.

Based on the two-layer target architecture in the development platform provided by the invention, an application developed based on the two-layer target architecture is generated, and the application provides services to the outside.

The invention discloses a service request method and a service request device, which are applied to the application based on target architecture development, can greatly reduce the development requirement, can also reduce the development code amount, and further improve the research and development efficiency.

Referring to fig. 1, a flowchart of a service request method according to an embodiment of the present invention is shown. The service request method comprises the following steps:

In specifically performing the process of step S101, a service request sent by a user through the service invocation interface is received, and a service requested by the service request is determined. For example, if the service request sent through the service call interface is received as a login request, it is determined that the service requested by the service request is a login service.

S102: at least one component of the service invocation is determined.

At least one component comprises a database component and/or a business function component, wherein the database component is used for calling a database, and the business component is used for realizing the business logic function of the service.

It should be noted that the service may be a user information management service, a data processing service, or the like. One service includes a plurality of services, and the user information management service includes a plurality of services such as a login service and a registration service. The present invention can be set according to practical applications, and the embodiments of the present invention are not limited.

In the specific implementation of step S102, by determining the service requested by the service request and further determining at least one component called by the service, the at least one component may only include the database component, or only include the business function component, or include both the database component and the business function component. For example, when the service requested by the service request is determined to be a login service, at least one component called by the login service is determined, the component called by the login service may include only a database component, or the component called by the login service includes only a business function component, or the component called by the login service includes both a database component and a business function component.

It should be noted that a plurality of business function components can be called in one service.

Further, in the embodiment of the present invention, when it is determined that the service requested by the service request is a simple function, that is, when the operation on the database is not involved and the business operation is not involved, the operation of the function may be completed according to the service itself, so as to obtain the request result of the service request, and the request result of the service request is obtained without calculating and/or operating the database through the invoked at least one component. For example, when it is determined that the service requested by the service request is a logical calculation, the calculation result may be obtained by performing the logical calculation according to the service itself, and the request result of the service request may not be obtained by at least one component called by the service through calculation and/or operating the database.

S103: invoking at least one component to generate a request result for the service request via the computation and/or manipulation of the database.

S104: and when the request result comprises at least one piece of data information, automatically constructing and returning an object carrying the request result.

In the specific process of executing step S104, it is determined whether an object carrying a request result needs to be automatically constructed and returned by determining the number of data information in the request result of invoking at least one component to generate a service request through calculation and/or operating a database. And when the request result generated by calling at least one component through calculation and/or operation of the database comprises at least one piece of data information, automatically constructing and returning an object carrying the request result.

On the contrary, if the request result generated by calling at least one component through calculation and/or operation of the database does not contain data information, that is, the number of the data information in the request result is 0, the object bearing the request result is not constructed.

The invention provides a service request method, which comprises the steps of receiving a service request, determining a request requested by the service request, and determining at least one component called by the service, wherein the at least one component comprises a database component and/or a business function component, the database component is used for calling a database, the business function component is used for realizing the business logic function of the service, and when the request result comprises at least one piece of data information, an object carrying the request result is automatically constructed and returned. According to the technical scheme provided by the invention, at least one component for service calling is determined, and then the at least one component is called to generate the request result of the service request through calculation and/or operation of the database, so that the request result of the service request can be obtained only by realizing two types of objects of service and component, the development structure is simple, the development requirement can be greatly reduced, the development code amount can be reduced, and the development efficiency is further improved.

In the above embodiment of the present invention, step S103 disclosed in fig. 1 invokes at least one component to generate a request result of the service request through calculating and/or operating the database, and when the at least one component includes a database component, as shown in fig. 2, the method includes the following steps:

The parameter sequence comprises at least one piece of parameter information which is sequentially ordered, and the parameter information comprises parameters and parameter values.

It should be noted that the database operation statement identifier included in the database operation statement information is used to uniquely identify one database operation statement template, for example, the database operation statement template may be an sql statement template.

For example, the database operation statement information called by the database component runtime is: a String sinstname (String) dbcmpt. search object (QRY _ GETINSINAME, sintcode 1 sintcode 2 sintcode 3), a database operation statement in the database operation statement information is identified as QRY _ GETINSINAME, the QRY _ GETINSINAME is used for uniquely identifying a database operation statement template, a parameter sequence in the database operation statement information includes at least one parameter information, and the at least one parameter information is ordered in the parameter sequence as parameter information 1, parameter information 2 and parameter information 3, wherein the parameter information 1 includes parameter value sintcode 1 corresponding to parameter a and parameter a, the parameter information 2 includes parameter value sintcode 2 corresponding to parameter B and parameter B, and the parameter information 3 includes parameter value sintcode 3 corresponding to parameter C and parameter C.

S206: and obtaining a request result of the service request based on the data operation result.

It should be noted that, when at least one component only includes a database component, the data operation result is a request result of the service request. However, when at least one component includes not only the database component but also the business function group price, the data operation result is obtained by operating the database through the database component, and the request result of the service request is obtained by further calculating the data operation result through the business function component.

In the embodiment of the invention, the database operation statement information called when the detection database component operates may only include the database operation statement identifier, at this time, the database operation statement template found according to the database operation statement identifier in the database operation statement information is a static database operation statement template, the static database operation statement template does not carry variables, and the static database operation statement template is a database operation statement, so that a database interface can be directly called to execute the static database operation statement template (database operation statement) to operate the database to generate a data operation result, and then a request result of the service request is obtained according to the data operation result.

It should be noted that, when the database operation statement is a query statement, the request result includes at least one piece of data information.

In the process of specifically executing step S301, data information is carried by obtaining the POJO class (object structure) corresponding to the object structure identifier, and if the type of the data information in the request result is the basic type, the java basic type object may be directly invoked to carry the data information.

Furthermore, it should be noted that, when the database component runs the database operation statement to operate the database, the returned data information may be specified to be carried by the corresponding POJO class, and when the returned data information is specified to be carried by the corresponding POJO class, the database component may automatically fill the accessed data information into the corresponding POJO class.

S302: and constructing an object list, wherein the object list comprises at least one data object, and the data object is an object structure carrying one piece of data information.

In the specific process of performing step S302, the data information in the request result is stored in the object structure, so as to obtain the data object corresponding to the data information in the request result, for example, when the number of the data information included in the request result is 10, the 10 pieces of data information are stored in the object structure, so as to obtain 10 data objects corresponding to the 10 pieces of data information, and then an object list is generated based on the 10 data objects.

S303: the object list is returned.

For a better understanding of the above, the following examples are given.

For example, when the request result includes 10 pieces of data information, an object structure for carrying the data information corresponding to the object structure identifier is obtained, the data information is stored in the object structure for each piece of data information to obtain a data object corresponding to the data information, thereby obtaining 10 data objects corresponding to the 10 pieces of data information, and then an object list is generated based on the 10 data objects.

In the embodiment of the application, when the request result includes a plurality of pieces of data information, the data object is obtained according to the object structure for bearing the data information, which is obtained and corresponds to the object structure identifier, and then the object list is constructed according to the obtained data object, where the returned object list includes at least one object structure.

And when the request result only comprises one piece of data information and the data information comprises a plurality of pieces of field information, according to the object structure which is obtained and corresponds to the object structure identification and is used for bearing the piece of data information, returning the object structure. Of course, an object list may also be constructed according to the data objects obtained by the object structure, and the returned object list includes only one data object.

And when the request result only comprises one piece of data information and the data information only comprises one piece of field information, acquiring a Java basic object for bearing the data information and returning the Java basic object.

For example, if the service request requested by the user is to query all school information read by the user, invoking at least one component to generate a request result of the service request including at least one piece of data information through calculation and/or operating a database, obtaining a data object according to an object structure for bearing the data information, which corresponds to the object structure identifier, further constructing an object list according to the obtained data object, and returning the object list.

If the service request requested by the user is to inquire the unit information (unit name, unit address and the like) where the user is located at present, calling at least one component to generate a request result of the service request through calculation and/or operation of a database, wherein the request result only comprises one piece of data information, and returning the object structure according to an object structure which is used for bearing the piece of data information and corresponds to the object structure identification.

If the service request requested by the user is to inquire the unit name or the unit address where the user is located at present, calling at least one component to generate a request result of the service request as field information, namely the unit name or the unit address, through calculation and/or operation of the database, acquiring a Java basic object for bearing the data information, and returning the Java basic object.

In the embodiment of the invention, the data object is obtained by obtaining the object structure which is corresponding to the object structure identification and used for bearing the data information, and then the object list is constructed according to the obtained data object.

As shown in fig. 4, the building object list related in step S303 disclosed in fig. 3 in the embodiment of the present invention is a schematic flowchart illustrating a process of building an object list provided in the embodiment of the present invention, and includes the following steps:

s401: and obtaining paging information carried in the service request, wherein the paging information indicates the information quantity displayed on each page and the requested page number.

In the specific execution of step S401, the number of pieces of information displayed per page refers to how many pieces of information are displayed per page. Therefore, by acquiring the paging information carried in the service request, it is possible to determine how many pieces of information need to be displayed per page and the page number requested to be queried by the user.

S402: and paging the data information in the request result by using the information quantity displayed in each page to obtain a paging result.

It should be noted that, when the number of pages requested to be queried by the user exceeds the preset number of pages to be queried, the query request of the user is rejected.

In the specific implementation of step S402, the data information in the request result is paged by using the quantity of information displayed per page to obtain a paging result, for example, 10 pieces of information need to be displayed per page, and if there are 100 pieces of data information in the request result, the paging result obtained by paging the data information in the request result by using the quantity of information displayed per page is 10 pages.

S403: and determining data information in the page number according to the paging result.

In the specific process of step S403, it can be determined from the paging result that the data information in the page number used for requesting query is, for example, 10 pieces of information need to be displayed per page, and there are 100 pieces of data information in the request result, then the paging result obtained by paging the data information in the request result by using the amount of information displayed per page is 10 pages, and the page number requested to be queried by the user is the 5 th page, and then the data information in the page number requested to be queried by the user is determined to be the 40 th to 50 th pages according to the paging result.

S404: and constructing an object list by using the determined data information.

It should be noted that the returned object list includes returned page information, and the page information is generated based on the paging result and the object list.

In the specific process of executing step S404, the object list includes at least one data object, and each data object is an object structure carrying one piece of data information, for example, the number of data information in the request result is determined to be 10, and since each data object is an object structure carrying one piece of data information, the determined data information is used to construct the object list, which includes 10 data objects.

In the embodiment of the invention, the data information in the request result is paged by utilizing the displayed information quantity of each page in the paging information carried in the acquired service request and the requested page number to obtain the paging result, and the data information in the page number is determined according to the paging result to further construct the object list.

Optionally, on the basis of the service request method disclosed above in the present invention, when the indication requested by the service request detects an application, as shown in fig. 5, the method further includes:

s501: for each service in the application, all calling relations in the service are obtained based on the script of the service.

It should be noted that the service indication detection application refers to: the method is used for requesting to detect the legality of the application, and the legality of the application can be determined only under the condition that the legality of the application is met, so that the application can be used.

S502: and judging whether the calling relation meets a preset condition or not.

It should be noted that, when the calling relationship satisfies the preset condition, step S503 is executed.

It should be noted that the preset conditions include that one service in the application does not call a non-shared component of other services in the application, a component in the application does not call a non-shared component, a component in the application does not call a service, and a service in the application does not call a service.

It should be noted that, a component carries identification information, when the identification information indicates sharing, the component is indicated as a shared component, and when the identification information indicates non-sharing, the component is indicated as a non-shared component.

Further, it should be noted that, when the component is a database component, the database component serves as a common basic component and can be called by any service and component.

S503: the application is determined to be legitimate.

In the process of specifically executing step S503, when all the call relations in the service in the application satisfy the preset conditions that the service does not call the non-shared component of other services in the application, the component in the application does not call the non-shared component, the component in the application does not call the service, the service in the application does not call the service, and the like, it is determined that the application is legal.

On the contrary, as long as all the calling relations in the service in the application have the condition that the service does not call the non-shared components of other services in the application, the components in the application do not call the non-shared components, the components in the application do not call the service, and the service in the application does not call any one or more of the services, the application is determined to be illegal.

In the embodiment of the invention, whether the application is legal or not can be determined by judging whether all the calling relations in the obtained service meet the preset condition or not, and further whether the application can be used or not can be determined.

In the above embodiment of the present invention, step S501 disclosed in fig. 5 obtains all call relations in the service based on the script of the service, as shown in fig. 6, includes the following steps:

S602: and analyzing the service class to obtain the service to which the service belongs and the first attribute of the service, wherein the first attribute comprises the calling relation in the service.

It should be noted that the first attribute of the service can be obtained by parsing the service class through the Java reflection mechanism. The present invention can be set according to practical applications, and the embodiments of the present invention are not limited.

In the specific process of executing step S602, the calling relationship in the service refers to the calling relationship between components in the service and the calling relationship of components inside the components called by the service, for example, the service calls component 1, component 2, component 3, and component 4 at runtime, component 2 needs to call component 5 at runtime for implementation, component 3 needs to call component 6 and component 7 at runtime, then the calling relationship of the service is that the service calls component 1, component 2, component 3, and component 4, the calling relationship of the component in the service calls component 5 for component 2, and component 3 calls component 6 and component 7.

S603: and analyzing the component class to obtain a second attribute of the component called in the service, wherein the second attribute comprises a calling relation in the component called in the service.

In the process of specifically executing step S603, the calling relationship in the service-called component refers to the calling relationship of the component inside the service-called component, the service calls component 1, component 2, component 3, and component 4 during running, the component 2 needs to call component 5 during running to implement, and the component 3 needs to call component 6 and component 7 during running, where the calling relationship of the service-called component calls component 5 for the component 2, and the component 3 calls component 6 and component 7.

In the embodiment of the invention, the calling relation in the service and the calling relation of the components in the service can be obtained by analyzing the called service class and the component class in the acquired script of the service, and when the calling relation in the service and the calling relation of the components in the service meet the preset conditions, the application can be determined to be legal, so that the application can be determined to be used.

In order to better understand the above, the application code of the service layer and the application code of the component layer are exemplified below.
