Detailed Description
As shown in fig. 1 to 3, the method for rapidly developing the project management system by using the extension component comprises the following steps:
1) According to the requirements of the project management system, a project management system sub-module frame is established, and the functions of all sub-modules of the project management system are determined;
2) According to the functions of each sub-module, the common requirement and the independent requirement of each sub-module are summarized, and a corresponding extension component (the programming language of the embodiment is JAVA) is established according to the following steps:
2-1) establishing and naming an expansion component constructor according to the requirements of the sub-modules, wherein the constructor comprises HTML content to be rendered by the expansion component;
the requirements of the sub-module generally refer to the function that the sub-module needs to complete, and according to this function, an extension component constructor is defined in JAVA, the name of the extension component constructor is determined, and HTML content to be rendered by the extension component is declared, such as show, close, search, add, edit, delete, init, get data, save, and the like.
2-2) registering the constructor of step 2-1) as an extension component of the project management library in the development platform of the operating system, and associating the data processing method of the extension component with the corresponding database field, for example, an extension component is named as a "personnel component", and one of the data processing methods of the "personnel component" is named as a show method and another is named as an add method, and then, it is necessary to associate both "show" and "add" with the corresponding personnel database field.
The established extension assembly comprises a commonality assembly and an independent assembly, wherein the commonality assembly and the independent assembly are composed of a data processing method corresponding to the assembly, a plurality of form parameters and attribute labels.
In a process-oriented computer programming language, a "data processing method", i.e. a function of a computer, is a fixed program segment, which has an entry and an exit while realizing a fixed operation function, the entry being the transfer parameters carried by the function, through which the parameter values of the function are substituted into the program for processing by the computer; the term "exit" refers to a function value of a function, and after the function is obtained by a computer, the function value is returned to a program calling the function.
The computer programming language adopted in the embodiment is JAVA, which is an object-oriented computer programming language, and the "data processing method" refers to a method in JAVA.
"formal parameters" generally refer to transfer parameters, i.e., the various parameters involved in the transfer of a function. The parameter transmission is to transmit the parameter value to the corresponding form parameter by the actual parameter in the program operation process, then to realize the process of data processing and returning in the function, and the method is to transmit the parameter by value, the parameter by address and the parameter by array.
Therefore, the expansion component can be understood as obtaining a set of independent and universal html tags through encapsulation of the common html tags, and the encapsulated component can be called by using the tags to transmit corresponding parameters in the page.
In project management software engineering, the authorization of each sub-module is associated with a user, and because the users logged in at the same time are unique, the common component can be understood as a global component, namely any instance in a page can be used, and specific component labels are used for distinguishing, and all the component labels are determined by the attribute labels of the expansion component; the independent component can be understood as a local component, can be used only in the corresponding examples, needs to load the component template and the component style at the same time, and cannot be commonly used in all the examples.
The attributes of the extension component include data attributes and method attributes, both marked by an "attribute tag".
(1) When the attribute of the expansion assembly is a data attribute, the expansion assembly receives external incoming data and processes the data inside the expansion assembly;
(2) when the attribute of the extension component is a method attribute, the extension component can call back the method of the extension component after completing a specific task, and trigger the external component to execute a process.
For example, when defining the expansion components such as personnel components, organization components, graphic components, project components, contract components and the like, the expansion components need to be packaged according to the functions of the components, so that each expansion component has a corresponding data processing method and a data display mode.
3) According to the project management system sub-module framework, each sub-module of the project management system is built by utilizing a plurality of expansion components according to the following steps:
3-1) creating a sub-module page table, wherein the sub-module page table comprises a module number, a module name, a page address and a top page file selection item;
3-2) adding corresponding expansion components into the sub-module page table according to the corresponding functions of the sub-module page table, and configuring the expansion components of the sub-module page table, and the associated attribute and the data processing method of each expansion component;
the associated attribute of each extension component is determined by the "attribute tag" to which the extension component corresponds.
3-3) establishing a sub-module function table, and storing all functions of the sub-module into the sub-module function table, wherein the sub-module function table comprises function numbers and function names;
3-4) establishing a sub-module resource table, wherein the sub-module resource table comprises the corresponding relation between pages and functions, and page numbers, page names and function names;
3-5) creating a sub-module menu list, and generating a corresponding sub-module menu:
the method comprises the steps that a sub-module menu authorization table is created, when a user role is authorized, an authorization menu is selected, and codes of authorization resources, function codes, menu codes and role codes are stored in the menu authorization table;
secondly, when a user logs in the system, creating menu data to be displayed, detecting whether the user has a resource ID and a function ID in a menu authorization table, and if so, adding the menu data into a menu array;
3-6) when the creation of the sub-module menu is completed, associating the sub-module menu to the page header of the sub-module.
In summary, the extension component built in the invention can put the general form component, button and dialog box component on the picture according to the function requirement, so as to realize the function of the corresponding sub-module.
4) And forming each established submodule into a project management system meeting the requirements, wherein the project management system submodule framework comprises a view data layer, a data model and a view layer, the view layer is used for establishing a user interface, the data model is used for carrying out data manipulation and business logic processing around a project management database system, and the view data layer is used for acquiring data to carry out secondary packaging on an expansion assembly so as to generate a view data model meeting the requirements of the view layer.
As shown in FIG. 4, the core of the project management system sub-module framework is the ViewModel, which is a view data layer that is generated and maintained by the front-end developer organization. At this level, the front-end developer performs conversion processing on the Model data acquired from the background, and performs secondary packaging to generate a View data Model conforming to the View layer usage expectations. After the most complicated work is completed by constructing the framework, a developer only needs to process and maintain a view data layer (ViewModel), and the updated data view can be automatically updated correspondingly, so that event-driven programming is truly realized.
The View data layer (ViewModel) carries out bidirectional data binding with the View layer (View) upwards, and carries out data interaction with the data Model (Model) through interface request downwards.
The View layer (View) is also the user interface that is seen. The front end of the general View layer (View) is mainly constructed by HTML and CSS, and in order to more conveniently present data of the View data layer (View Model) or the data Model (Model), various template languages, such as FreeMarker, thymeleaf, etc., have been generated, and each large MVVM frame, such as vue.
The data Model (Model), which is generally referred to as various business logic processes and data manipulation performed in the background, mainly extends around the database system, and needs to agree with a unified interface rule with the front end.
The View layer (View) is responsible for interacting with the data Model (Model) instead of the data Model (Model), and not only can update the content corresponding to the View layer (View) according to the data change of the data Model (Model), but also can monitor the change of the View layer (View) and modify the data of the data Model (Model) according to the change.
According to the invention, before each new sub-module is generated, different expansion components are established according to requirements, so that development time of a software development engineer is greatly saved, development quality of software is improved, development difficulty is reduced, subsequent debugging and testing work efficiency is obviously improved, compared with the existing application software development method only by using a framework, overall software development workload is reduced by more than 70%, and by taking the realization of role authority function as an example, because application software carries out data bidirectional binding between a view data layer and a view layer through the expansion components, each expansion component is associated with a corresponding database field before each sub-module is generated. Once the application software is generated, the developer does not need to do any programming work in terms of database operation and configuration, when the view data layer observes that the data in the data source changes, the application software can automatically modify the content of the view layer correspondingly, and when the view data layer monitors that the view layer changes, the application software can automatically modify the corresponding data in the data source.
Notably, the data bi-directional binding is necessarily for UI controls, and non-UI controls do not involve data bi-directional binding.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the invention, and those skilled in the art will appreciate that the modifications made to the invention fall within the scope of the invention without departing from the spirit of the invention.
