Description

Automatic generation device and automatic generation method of web system

technical field

The present invention relates to the technical field of data processing, in particular to an automatic generation device for a web system and an automatic generation method for a web system.

Background technique

In the development of the web system, when designers are faced with how to structure the web system to achieve more convenient and concise development, the MVC (model (model)-view (view)-controller (controller)) architecture pattern has gradually become mainstream technology. MVC is a software component pattern that organizes code with a method of separating business logic and data display. The premise of this method is that if business logic is gathered into a component, and the interface and user interaction around data can be improved and Personalization without rewriting business logic. MVC is applied to map traditional input, processing and output functions in a logical GUI structure.

MVC separates the implementation code of M (model layer) and V (view layer), so that the same program can use different forms of expression. For example, a batch of statistical data can be represented by histograms and pie charts. The purpose of C (control layer) is to ensure the synchronization of M (model layer) and V (view layer). Once M (model layer) changes, V (view layer) should be updated synchronously. It enforces separation of application input, processing, and output. Based on the above principles, web applications are divided into three core components: model, view, and controller, each of which handles its own tasks.

Nowadays, there are many mature and widely used MVC architecture solutions in the industry, such as Struts, Spring, Hibernate, etc. When they use the MVC design pattern for web system architecture, they are fully able to closely associate the decoupled C (control layer) and M (model layer) through configuration files and are independent of each other, and through strategy patterns and aspect-oriented programming technology, which can intelligently and automatically generate codes for parts M (model layer) and C (control layer).

However, the various MVC solutions proposed in related technologies still remain in the automatic generation of code at some levels, or partial automation at a certain level, and cannot provide a complete set of technical solutions to perform MVC operations on the entire level that have nothing to do with business logic. Automated generation of code.

Therefore, how to provide a new web system development technology to make the development of the web system more automatic, to allow program developers to focus more on specific business logic, and to improve work efficiency.

Fig. 3 shows a schematic diagram of the principle of an automatic web generation system according to an embodiment of the present invention.

The working principle of the automatic web generation system based on the embodiment of the present invention will be described in detail below with reference to FIG. 3 .

It is assumed that the web system development platform of the present invention includes a basic platform system 302, and other specific functions such as a view layer platform 302A, a model layer platform 302B, a control layer platform 302C, etc., to realize the development of a specific web system .

When web system development needs to be performed, the platform system 302 needs to read the settings or configurations made and completed by the user in advance, so as to realize system initialization and function configuration.

First, the automatic generation of the view layer

In this embodiment, the automatic generation of the view layer is mainly realized by the view layer platform 302A. Specifically, the human-computer interaction process can be realized through the browser, and the user only needs to drag the mouse and operate the keyboard to realize the generation of the page.

1. View type

The user selects the required view type according to the requirement, such as HTML, jsp, freemarker, etc.

2. Design drawing

Specifically, the view layer platform 302A needs to provide a visual view control, and the user can use the mouse to select and drag the view control to form a corresponding design drawing according to their own needs. For example, the view controls can use the controls in the W3C (World Wide Web Consortium, World Wide Web Consortium) standard. You only need to understand the relevant specifications of W3C, and you don't need to spend any time and effort to learn new controls and APIs.

3. Form

The view layer platform 302A can automatically generate a corresponding form according to the view type selected by the user and the design drawing on the design platform.

Among them, the association and interaction between the view controls on the form can be realized by JavaScript and DOM technology. For example, some basic DOM operations (methods) are provided in the view layer platform 302A for programmers to choose; at the same time, programmers can also customize DOM methods and associate them with specific view controls. The interaction between the form and the background can be done in a way such as ajax, or by generating a temporary form tag and submitting it.

4. Embodiment of "login interface"

Assuming that the user needs to design a "login interface" web system, the generation process of the view layer includes:

1) On the control selection interface of the view design platform 302A, drag a user name input box (input-text label) and a password input box (input-password label), and drag two buttons: "login" (input -button tag), "reset" (input-button tag).

2) Select the type of form to be generated (such as JSP, HTML, etc.): jsp; enter the form ID (unique mark): login.jsp.

3) Edit the properties of each view control. For example, double-click the user name input box to edit properties, enter ID: userName; double-click the password input box to edit properties, enter ID: userPassword; double-click the login button to edit properties, enter ID: loginButton, enter the submission URL: login.do; enter the form to be submitted ID: loginForm; double-click the reset button to edit properties, enter ID: resetButton; enter the ID of the form that needs to be reset: loginForm.

4) The view layer platform 302A will automatically generate javaScript methods for each view control. For example, submit to loginButton: generate a temporary form with ID: loginForm, the content includes all input objects on the page (password input box, password input box); action: login.do; finally form.submit().

Of course, if the user needs to write a javaScript method to log in, he can edit the event attribute of the login button and change it to a custom method.

5) The automation device generates the corresponding form interface in the background according to the previous series of design steps.

2. Automatic generation of model layers

1. JavaBean

The model layer platform 302B uses dynamic proxy technology, uses the form ID as the class name of the JavaBean (generates a corresponding JavaBean for each form), and all html input tags on the form correspond to the properties of the JavaBean, and automatically generates the corresponding JavaBean.

2. Database

Obtain the information contained in the generated JavaBean, that is, the attribute information of the view control in the corresponding form in the view layer, and automatically generate the corresponding database script according to the JavaBean information and the selected database type, version and framework.

Through the database script generated above, the database table corresponding to the JavaBean (for example, the ID of the database table is the same as the ID of the JavaBean and the ID of the corresponding form) is automatically generated, and the fields in the database table correspond to the attributes in the Javabean one by one, thus completing The creation of the database.

At the same time, each JavaBean inherits a basic class, which mainly associates JavaBean with database operations, and can realize operations on the database, such as adding, deleting, modifying, and checking.

3. Action

In fact, JavaBean can directly respond to the request of the control layer to perform operations on the database, but in order to distinguish different functions and facilitate system debugging and division of labor, the system also creates Actions to share the request to the control layer.

Action is a business processing class. It is an operation class with basic database operations (addition, deletion, modification, query, etc.) generated according to the properties and methods of JavaBean. The Action can operate the database by calling JavaBean.

4. SQL statement template

While generating the Action, the model layer platform 302B will also generate a SQL configuration file corresponding to the Action to assist in supporting the Action's operation on the database. Specifically, the SQL configuration file contains SQL statement templates for database operations, so there is no need to regenerate SQL statements each time, but only to add associated data identifiers (such as database table IDs, etc.) to SQL statements according to the request of the control layer The corresponding position in the template is enough, which helps to improve work efficiency.

Of course, programmers can modify the Action or the SQL configuration file according to the actual situation; and the modification of the database operation function can also be automatically synchronized to the Action and SQL configuration files.

In the above technical solution, various input controls of the form are used as attributes by parsing the form page of the view layer, and corresponding functions (methods) are generated to obtain the JavaBean. The above-mentioned dynamic proxy technology can well associate the front view page with the specific business logic processing class of the background model layer, so that programmers only need to care about the processing of specific business logic, and do not need to consider the association and communication between the foreground and the background , thereby improving work efficiency.

5. Embodiment of "login interface"

1) According to the generated form, create a class in the background, whose name is based on the form ID (in order to establish a relationship): Login_jsp.java, and the attributes are consistent with the input controls of the form: username, usePassword; corresponding methods: getUserName(), setUserName (), getUserPassword(), setUserPassword().

2) Generate SQL scripts. The specific code can be:

3) Generate the base class. The specific code can be:

4) Generate the Action class. The specific code can be:

3. Automatic generation of the control layer

1. User Configuration

After the control layer platform 302C initializes the system configuration, it enters the control layer management interface 304, and automatically generates the control layer according to the configuration of the user.

Users need to generate corresponding configuration files in advance for the initial configuration of the control layer and the function configuration during the control process. Users do not need to specifically write the function code of the configuration file. They only need to select or create the object and method to be operated, and the corresponding code can be automatically generated by the background. For example, for the path specification, it is only necessary to directly create the path. ; For specifying the operation object, you only need to select the object directly.

2. Processing logic

In addition to the above configuration, specific processing logic needs to be set.

1) The control layer platform 302C provides a variety of preset frameworks, and the user can directly select one of them, and the control layer platform 302C can directly apply the processing logic corresponding to the selected framework to the current web system. Specifically, it is realized by writing the above processing logic into web, xml and other types of configuration files.

2) Programmers can also redefine the processing logic according to the actual situation instead of choosing the predefined framework. Specifically, for example, the control layer platform 302C will automatically generate an interceptor class to intercept the request URL ending in a certain format configured by the programmer.

More specifically, such as: the programmer configures the system URL suffix name .do on the control layer management interface 304, then the platform system 302 will automatically generate a controller to intercept all requests with the suffix name . The configured path and ID are sent to the interceptor as the request URL. The interceptor parses the obtained URL and distributes it to the corresponding Action (business processing class).

3. Embodiment of "login interface"

1) The login interface (form) is set to be submitted to login.do on the view layer design platform 302A.

2) Configure an interceptor on the controller management interface 304 to intercept all .do requests.

3) Write the configuration related parameters into the web.xml file of the automatically generated system.

4) When the login button is clicked, the parameters will be sent to login.do, and the interceptor in web.xml intercepts the request (request), then parses the request and sends it to loginAction, and then the loginAction handles it specifically Database operations and other processing procedures.
