  FIG. 2 is a block diagram illustrating an example of a hardware configuration of the program generation device according to the embodiment of the present invention.

  The same components as those in FIG. 1 are denoted by the same reference numerals. As shown in FIG. 2, the program generation device shown in FIG. 1 can be realized by a personal computer or the like.

  The CPU 201 is configured to comprehensively control access to various devices connected to the system bus based on a control program stored in the ROM 203 or the external storage device 104.

  The system bus is connected to a RAM 202 that functions as a main memory, work area, and the like for the CPU 201. The ROM 203 or the external storage device 104 implements a process executed by a BIOS (Basic Input / Output System), an operating system (hereinafter referred to as “OS”) program, and a processing device (computer) 103 which are control programs of the CPU 101. Various programs necessary for this purpose are described.

  The CPU 201 implements the functions and various functions of the overall control unit 108 shown in FIG. 1 by loading various programs necessary for execution of processing into the RAM 202 and executing the programs.

  The external storage device 104 can store a boot program (not shown), various application programs, font data, user files, and the like as the various programs described above.

  For example, the CPU 201 performs WYSIWYG on the display device 102 by executing outline font rasterization processing on a display information area in the RAM 202. Further, the CPU 201 opens various registered windows based on commands instructed by a mouse cursor (not shown) on the display device 102 and executes various data processing.

  FIG. 3 is a diagram illustrating an example of the overall configuration of an application system that uses the code generated by the code generation unit 107 of the program generation apparatus according to the embodiment of the present invention.

  A client 301 and a server 304 are communicably connected via a network. In response to a request from the client 301, screen display information is transmitted to the client 301 from the server 304 on which the program generated by the processing device 103 operates.

  Specifically, the servlet, JSP, and Bean generated by the code generation unit 107 are arranged on the application server 306 on the server 304 side in an executable state.

  This web application system is used from the client 301 by the web browser 302. By accessing the JSP 309 from the Web browser 302, an HTML page 303 is generated and transmitted to the client 301 side. Then, an HTML page 303 transmitted from the JSP 309 is displayed on the Web browser 302.

  A request from the Web browser 302 is transmitted to the server 304 side via HTTP. The server 304 includes an HTTP server 305 and an application server 306, and the application server 306 includes an execution environment for the servlet 307 and the JSP 309.

  When a request is transmitted to the server 304 side, the corresponding servlet 307 is activated according to the request. The servlet 307 requests the corresponding Bean 308 to perform processing. Further, the Bean 308 accesses the DB access object 310a, the internal database 311a, and the external database 311b in response to a request from the servlet 307, and holds the processing result in the Bean 308.

  Next, the Bean 308 is passed from the servlet 307 to the JSP 309 and the JSP 309 is called. The JSP 309 refers to the processing result held by the Bean 308, generates an HTML page, and returns it to the client 301 side. The HTML page returned to the client 301 is displayed on the Web browser 302.

  The servlet 307 has a role of controlling the connection between the reception of a request from the Web browser 302, the processing request to the Bean 308, and the call to the JSP 309. The JSP 309 is responsible for processing related to display for outputting an HTML page, and the Bean 308 is responsible for processing related to operations such as access to the databases 311a and 311b.

  Although it is possible to process a request from the Web browser 302 using only the servlet 307 without using the Bean 308 or JSP 309 (or using only the JSP 309 without using the servlet 307 or Bean 308), the Bean 308 or JSP 309 can be processed. By clearly separating each role using the function, it is possible to grasp the functional division in a concise manner.

  Note that the Bean 308 may be separately implemented as a Bean for internal database access and a Bean for external database access.

  FIG. 4 is a flowchart showing an example of a first control processing procedure in the program generation device showing an embodiment of the present invention.

  This corresponds to the operation of the overall control unit 108 of the processing apparatus 103 shown in FIG. In addition, S401-S405 shows each step.

  First, when the overall control unit 108 is activated, in step S401, it is determined whether the processing (mode) selected by the operator's instruction from the input device 101 is generation (mode) or input (mode), and the input mode is selected. When it is determined that it has been performed (N), the process proceeds to step S402, and the overall control unit 108 activates the screen control unit 105.

  In step S403, the activated screen control unit 105 causes the business specification description unit 106 to display a business specification input screen (details are shown in FIG. 8), and sets display items that are forms of business specifications from the operator. Settings such as the layout and input control type are accepted, the input / output table 109 is stored in the external storage device 104, and the process ends.

  On the other hand, if it is determined in step S401 that the mode selected by the operator's instruction from the input device 101 is the generation mode, the process proceeds to step S404, and the overall control unit 108 receives the input stored in the external storage device 104. The output table 109 is read, and code generation is performed based on the business specification information in the read input / output table. Details of the code generation (program generation) process are shown in FIG.

  In step S <b> 405, the overall control unit 108 displays the generated code on the display device 102 in accordance with an instruction from the operator, or performs an output process of writing to the external storage device 104, and ends the process.

  FIG. 5 is a flowchart showing an example of the control processing procedure of the code generation processing in the program generation device showing an embodiment of the present invention.

  Steps S501 to S502 are processes operated by the developer, and steps S503 to S513 are processes performed by the program generation apparatus. The developer may perform an operation from an administrator terminal, or may perform an operation by directly accessing the program generation device.

  In step S501, the input of definition of the correspondence between the screen item input control and the data number threshold is received from the developer, and in step S502, the press of the program generation processing button on the development management screen is received. A development management screen operated by the developer will be described with reference to FIG.

  FIG. 8 is a diagram showing an example of a development management screen of the program generation device showing an embodiment of the present invention.

  The development management screen 801 corresponds to the business specification input screen activated in step S403 in FIG. In the item setting 810, settings relating to items to be displayed are performed, and in the input control type setting 820, settings relating to input controls to be displayed and conditions thereof are performed.

  In the item name 811, an item name (for example, “device classification”) to be displayed on the screen is input. The acquisition source 812 specifies a database from which data to be displayed is acquired. The item name 811 is an item stored in the designated database.

  The layout correction 813 designates exception processing with the content determined in the input control type setting 820. In the type 814, input control is input, and in the number of characters 815, the restriction on the character string to be displayed is input. The setting is valid when the layout correction 813 is checked, and invalid when the check is removed.

  Here, since the type 814 is set to “radio button” and the number of characters 815 is set to “combo box for 30 or more characters”, the combo box is displayed even if the radio button is displayed by the setting of the input control 820. A box will be displayed.

  In the layout correction 813, “radio button”, “30”, and “combo box” can be arbitrarily designated by the developer. For example, it can be set to switch to a combo box when the length of a displayed character string exceeds a predetermined length, not the number of characters to be displayed.

  In the input control 1 to the input control 3 (821 to 823), the number of cases FROM 824 and the number of cases TO825 are designated, and the type of input control 826 to be displayed is set. The number of items is the number of items that are referred to in order to be selected by the input control and stored in the acquisition source table (FIG. 7), and the type of input control is switched according to the number of stored items. ing.

  In the case of the input control 1 (821), if the number stored in the code master is between 1 and 3, the input control for the device classification is a radio button. Similarly, in the case of the input control 2 (822), if the number of cases is between 4 and 10, it becomes a combo box. In the case of the input control 3 (823), if the number of cases is 11 or more, it becomes a dialog.

  When the save 830 is pressed, the input content is saved as definition information in an input / output table (definition information storage means). The input / output table may be saved as a database in a table format or as a file. When the open 840 is pressed, definition information stored in the past can be opened. When the program generation 850 is pressed, automatic program generation is started. Returning to the description of FIG.

  In step S503, when a program generation request is received from the development management screen, the process proceeds to step S504, where item setting information and definition information which is input control type setting information set in the development management screen are read from the input / output table, and in step S505. Perform an error check to see if there are any deficiencies in the entered content. The error check may be executed when the save 830 or the program generation 850 is pressed on the development management screen.

  The content of the error check is to check whether there is no overlap or contradiction in the range of the number FROM 824 and the number TO set in the input control type setting 820, and whether the same control of the type 826 is specified, and in step S506. If there is an error, the error is displayed on the development management screen in step S507, and the process is terminated.

  If there is no error, the process advances to step S508 to generate a program for acquiring the number of data items from the database designated by the definition information acquisition source 812 (1001, data item acquisition program in FIG. 10).

  In step S509, a program for acquiring data from the table of the selection value acquisition source 812 is generated (1004 in FIG. 10).

  In step S510, based on the layout correction 813 information of the definition information, it is determined whether or not layout correction is checked. If there is a check, the process proceeds to step S511. If there is no check, the process proceeds to step S512. .

  In step S511, a program for performing layout correction determination is generated based on the information set in the layout correction 813 information (1005 in FIG. 10, correction program).

  In step S512, a program for determining the input control to be displayed is generated based on the input control type setting 820 (1002 to 1003 in FIG. 10, input control determination program).

  In step S513, a screen program (FIG. 11) including a program for controlling the control type to be displayed generated in steps S503 to S512 is generated, and the process ends. The concept of the program (code) generation process will be described with reference to FIG.

  FIG. 12 is a diagram illustrating an example of a functional configuration of the code generation process according to an embodiment of the present invention.

  In implementing this invention from the application program automatic generation system in this embodiment, the necessary resources are extracted and described.

  FIG. 1 is a block diagram showing a configuration of a part that generates an application in the embodiment, and the same components as those in FIG. 1 are denoted by the same reference numerals.

  Based on the definition information (defined in FIG. 8) stored in the input / output table 109, the code generation unit 107 acquires information about screen items and input controls to be displayed and applies them to a file of a program template 1205 (not shown). Thus, the program 207 is automatically generated.

  The program 207 includes any or all of the JSP code 112, Servlet 113, and Bean code 114 shown in FIG.

  The program template defines the program structure of the application program to be generated. By embedding definition information defined on the development management screen in this template, for example, an application program (source code as shown in FIGS. 10 and 11). ) Can be generated.

  FIG. 6 is a flowchart illustrating an example of a control procedure of a process in which a code generated by the program generation apparatus according to the embodiment of the present invention generates a screen.

  In step S <b> 601, the server 304 receives a screen display request from the Web browser 302 of the client 301.

  In step S602, the selection value to be displayed on the screen item is acquired from the data table shown in FIG. 7, and the number of data is counted.

  In step S603, the input control to be used is determined based on the number of data items and the threshold value. Specifically, the input control determination program generated in step S512 determines the input control type of the screen item from the number of selection values acquired in step S602 and the input control type setting 820. The data table will be described with reference to FIG.

  FIG. 7 is a diagram illustrating an example of a table image of data displayed on a screen displayed by a code generated by the program generation device according to the embodiment of the present invention.

  8 is a table stored as a code master in the internal database 311a or the external database 311b and designated by the acquisition source 812 in FIG. Alternatively, it may be stored in the external storage device 104. (Data table storage means)

  The device classification is assigned a unique value (number) corresponding to the device name so that the device name can be specified. As the device name, the name described on the screen is displayed on the screen as the device name. The displayed data item is selected by the input control.

  As an example, four tables of the table 701 to the table 704 are described, but when actually used, one of these four is referred to.

  When the table 701 is the data table of the acquisition source, the number of selection values is 3, and the corresponding input control becomes a “radio button” according to the setting of the input control type setting 820.

  Similarly, when the table 702 is an acquisition source data table, the number of selection values is 10, and the corresponding input control is a “combo box”. In the case of the table 703, 15 cases result in “dialog”.

  When the table is 704, since the number of selection values is 3, the input control is a “radio button”. However, since the total character string exceeds 30 characters and matches the layout correction conditions, Combo box ". Thereby, for example, in the case of a radio button that displays selection items side by side, it is possible to prevent the problem that the selection items cannot be displayed if the character string is too long. Returning to the description of FIG.

  In step S604, the selection value is acquired from the data table of FIG. 7, and the process proceeds to step S605.

  In step S605, it is confirmed whether or not the layout correction 813 is checked. If it is checked, the process proceeds to step S606, and if it is not checked, the process proceeds to step S609.

  In step S606, it is determined whether or not the input control is a correction target. If it is a target, the process proceeds to step S607, and if not, the process proceeds to step S609. The target of the input control is the content set in the type 814, and the “radio button” is the target in this embodiment.

  In step S607, it is determined whether or not the total number of characters in the selection value is greater than a predetermined value. If there are more characters, the process proceeds to step S608, and if not greater (if it does not fit), the process proceeds to step S609. The target of input control is the content set with the number of characters 815, which means that “a character string is 30 characters or more”. For example, when the data table of the acquisition source is 704, the total number of characters of the selection value is 34 characters, which is larger than the predetermined value.

  In step S608, the input component is changed from a radio button to a combo box according to the content set with the number of characters 815, and the process proceeds to step S609.

  In step S609, HTML is generated from the selection value acquired in step S604 in the format of the input component determined in the processing in steps S602 to 608, is transmitted to the terminal that displays the screen (display control), and the processing is terminated.

  FIG. 9 is a diagram showing an example of a screen displayed by a code generated by the program generation device showing an embodiment of the present invention.

  The HTML generated in step S609 is displayed and is a device registration master maintenance screen.

  Screens 910, 920, and 930 (930-1, 930-2) display tables 701, 702, 704, and 703, respectively.

  The device registration master maintenance 910 is a display example when the data table is the table 701. In the device classification 911, three items registered in the table 701 are displayed so as to be selectable by radio buttons. The model number 912 is an area where the user can write arbitrarily (the same applies to 922 and 932). When registration 913 is pressed, it is registered in a database (not shown).

  The device registration master maintenance 920 is a display example in the case of the data tables 702 and 704. In the device category 921, a combo box is displayed so that data items can be selected. In the case of the table 702, the number of display items is 10, and in the case of the table 704, the number of characters is 34, so that the layout is corrected and displayed. .

  A combo box is a selection list and is a generic term for a drop-down list, a pull-down menu, and the like.

This is a display example when the device registration master maintenance 930 (930-1, 930-2) data table is a table 703. When the selection 933 is pressed while nothing is input in 930-1, a dialog 938 is displayed in 930-2. Therefore, for example, when “001” is selected and the search 936 is pressed, the display returns to 930-1, “001” is input to the device category 931, and “Desktop PC (space-saving type)” is displayed near the selection 933. .

  FIG. 10 is a diagram showing an example of a program generated by the program generation device showing an embodiment of the present invention.

  Reference numeral 1001 corresponds to the “program for acquiring the number of data items” generated in step S508 of FIG.

  Reference numerals 1002 and 1003 correspond to the “program for determining input control to be displayed” generated in step S512.

  Reference numeral 1004 corresponds to the “program for acquiring a selection value” generated in step S509.

  Reference numeral 1005 corresponds to the “program for performing layout correction determination” generated in step S511.
