Description

  The present invention relates to a distributed application setting information management system that manages setting information distributed and set in a Web application.

In the Web application, the setting for determining the operation of the application is performed in a setting file by XML or the like. In this case, the source code and the setting information are separated into files, which causes a problem that development efficiency is low. In order to solve this problem, an annotation technique has been used recently. This technology is coded by a special description method called annotation in the source code. However, it is difficult to manage the entire application because the setting information is distributed throughout the source code. Conventionally, such information must be managed separately by a design document, and there is no prior art in particular.
Patent Document 1 relates to a technique for monitoring the status of processes distributed on a network.
However, Patent Document 1 does not display setting values distributed and defined in one application module in a form that is easy for the system administrator to understand.

JP 08-314875 A (6th to 13th pages, FIG. 1)

Conventionally, values set by annotations must be managed manually, for example, in a separate design document. In this case, there may be a problem that design information differs between the actual setting of the application and the design document.
Conventionally, in order to change the setting and operate the application, it is necessary to change (program) the setting information of the setting file and the source code, and to modularize again as a Web application. In this case, there is a problem that it takes time to change the setting information, and it is difficult to realize that the setting information is changed on a trial basis and operated.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall configuration diagram showing a distributed application setting information management function according to Embodiment 1 of the present invention.
In FIG. 1, the execution module 13 constituting the Web application 12 that operates on the application server 11 sets information related to the operation in the source code by annotation (denoted by @). In FIG. 1, source code information including annotations obtained by analyzing the execution module 13 with a tool is written in a square of the execution module 13. For example, when the function displays the next screen after processing is completed, information on the next screen is set in the annotation.
The web application 12 operates on the application server 11. The setting information analysis function 15 (setting information analysis means) of the distributed application setting information management function 17 (distributed application setting information management system) is also executed on the application server 11 together. The setting information analysis function 15 extracts setting information (annotation information) from the Web application 12 being executed and passes it to the setting information browsing function 16 of the distributed application setting information management function 17. Note that information other than that described in the annotation may be extracted as the setting information.
The setting information browsing function 16 (setting information display means) compares the received setting information with an annotation definition file 18 (described later) created in advance, and displays the corresponding information.

FIG. 2 is a diagram showing a user interface image (screen transition information) of the setting information browsing function of the distributed application setting information management function according to the first embodiment of the present invention.
In FIG. 2, when the setting information browsing function 16 is activated and screen transition information is selected, the screen of the screen transition information 21 is displayed. A diagram showing the screen transition of the entire Web application 12 based on the setting information passed from the setting information analysis function 15 is displayed there. This figure consists of screens 22 and screen transitions 23. When any one of the screens 22 is selected 24, a screen of screen detailed information 25 is displayed. On the screen of the screen detail information 25, a screen name, an event name (button press etc.) of the screen, and a next screen name to be displayed after the event occurs are displayed. The event that the screen has is acquired from the SUBMIT type in HTML.
In this way, the setting information browsing function 16 displays the setting information in a form that is easy for the system administrator to understand.

FIG. 3 is a diagram showing a relationship between the annotation definition file of the distributed application setting information management function and the analysis result of the Web application setting information according to the first embodiment of the present invention.

The annotation definition file 18 includes a display template 33 for displaying setting information, and an annotation for defining which variable of which display template 33 corresponds to a parameter such as an argument used in the annotation for each annotation name. It consists of detailed information 32. The display template 33 is shown in FIG. 3 as a display template 33 for screen transition. FIG. 3 shows display templates for the next screen transition and the previous screen transition. The next screen transition is a transition to another screen. The previous screen transition means that the screen displayed before the current screen is stored and the display is returned to the stored screen.
In the annotation detail information 32, one annotation is described in one line, the notation format of the annotation is written on the left side of “:”, and this type of annotation is displayed at the beginning of the right side of “:”. The name of the display template 33 to be written is written, “→” is placed, and the variable name in the display template 33 corresponding to the parameter (“param0” in FIG. 3) in the annotation is written. If there are multiple parameters, write variable names separated by commas to the right of “→”. In the annotation of the type “@scr”, the parameter “param0” corresponds to “screen name” in the screen transition template 33. The parameter “param0” of the annotation “@next” corresponds to “next screen name”. In the Web application setting information analysis result 34 shown in FIG. 3, a screen in which a solid line arrow indicating the next screen transition comes out from a square in which “SCR1” is written, and the arrow enters a square in which “SCR2” is written. Display will be made.
FIG. 4 is a flowchart showing processing of the setting information browsing function of the distributed application setting information management function according to the first embodiment of the present invention.

Next, the operation of the setting information browsing function will be described with reference to FIG.
First, the web application 12 is activated (step 41). Next, the setting information analysis function 15 is also activated (step 42). The setting information analysis function 15 extracts annotation information from the execution module of the Web application 12 (step 43). The information is stored in a memory, file, database, or the like (step 44).
Next, the setting information browsing function 16 is activated (step 45). The setting information browsing function 16 acquires the annotation information held earlier (step 46). Next, the annotation definition file 18 is read (step 47) and compared with the annotation information acquired in step 46. The information that matches the annotation name of the detailed annotation information is incorporated into the display template 33, and the display information is constructed (step 48). Finally, it is displayed on the screen (step 49).

According to the first embodiment, it is possible to display information distributed and set in a Web application in an expression method that is easy for the system administrator to understand.
This facilitates confirmation of the Web application setting information, and can reduce development costs and treatment costs when a failure occurs.

Embodiment 2. FIG.
In the first embodiment, the centralized browsing of the distributed Web application setting information has been described. However, the setting information can be updated, and the second embodiment relates to this.

FIG. 5 is an overall configuration diagram showing a distributed application setting information management function according to Embodiment 2 of the present invention.
In FIG. 5, 11-13, 15, 17, and 18 are the same as those in FIG. In FIG. 5, the distributed application setting information management function 17 is provided, and in FIG. 5, the distributed application setting information management function 17 is provided with a setting information update function 51 (having functions of setting information display means and setting information change means). . The setting information update function 51 displays a user interface image similar to the setting information browsing function 16 of FIG. 1 and further has a function of reading the existing (currently operating Web application) source code 52 to change the setting information. And has a function of generating a new source code 53.

FIG. 6 is a diagram showing a user interface image (screen transition information) of the setting information update function of the distributed application setting information management function according to the second embodiment of the present invention.
In FIG. 6, 21 to 25 are the same as those in FIG. In FIG. 6, a generation button 64 is provided on the screen of the screen transition information 21, and a change button 61 and a browse button 62 are provided on the screen of the screen detailed information 25. When the change button 61 is pressed on the screen of the screen detailed information 25, the mode is switched to the change mode. In the change mode, the changeable portion becomes the input mode 62. In addition, when the browse button 63 is pressed, the screen is switched to the browse screen.

FIG. 7 is a flowchart showing Web application setting information update processing of the distributed application setting information management function according to the second embodiment of the present invention.
Since the activation of the Web application is the same as in the first embodiment, the description thereof is omitted. The same applies to the following embodiments.

Next, the operation of the setting information update function 51 will be described with reference to FIG.
First, the setting information update function 51 is activated (step 45A). Steps 46 to 49 are the same processing as in FIG. 4, and the screen of the screen detailed information 25 is displayed (step 49), and the mode is switched to the change mode (step 72). In the change mode, the changeable parameter portion is an input field, and the setting information is changed as necessary (step 73). The changed contents are held in the memory (step 74). When the change is finished, the screen of the screen detailed information 25 is closed and the screen of the screen transition information 21 is returned. At that time, the display information is reconstructed (step 75) according to the changed contents, and the screen display is updated (step 76). Therefore, when the generation button 64 is pressed, the source code stored in an arbitrary directory is read (step 77). Next, the contents of the change held earlier are reflected in the read source code (step 78). Finally, the changed source code is generated in an arbitrary directory (step 79).

  According to the second embodiment, information distributed and set in the Web application can be browsed and changed with a meaningful expression method. Since changes can be made while confirming with meaningful expressions, incorrect settings are eliminated, and development costs and treatment costs in the event of a failure can be reduced.

In FIG. 9, 21 to 23 and 64 are the same as those in FIG. On the screen of the screen transition information 21, a simulation button 91 and a simulation completion button 92 are provided. When the simulation button 91 is pressed in a state where the setting information has been changed, the simulation web application 82 in which the change is reflected is started. Further, when the simulation completion button 92 is pressed, the original Web application 12 is activated.

  FIG. 10 is a flowchart showing processing up to execution of simulation of Web application setting information of the distributed application setting information management function according to the third embodiment of the present invention.

Next, the operation of the setting information simulation function 83 will be described with reference to FIG.
Steps 45A to 79 are the same processing as in FIG. 7, and the simulation button 91 is pressed on the screen transition information screen (step 79) that has been changed. The source code of the simulation web application 82 that has already been generated is compiled (step 102), and a simulation execution module is generated (step 103). Next, the existing web application 12 is stopped (step 104), and a backup of the existing execution module is created (step 105). Finally, the module is replaced with a simulation execution module and activated (step 106). When it is desired to complete the simulation, the simulation completion button 92 is pressed on the screen transition information screen (step 107). The execution module of the Web application 12 that has been backed up is restored and activated (step 108).

FIG. 11 is an overall configuration diagram showing a distributed application setting information management function according to Embodiment 4 of the present invention.
11, 11 to 13, 15, 17, 18, 82 and 83 are the same as those in FIG. In FIG. 11, the setting information update function 111 does not use source code. The setting information simulation function 83 causes the execution module changing function 113 to generate a simulation execution module, and the setting information simulation function 83 does not compile source code or generate an execution module. The execution module changing function 113 (execution module changing means) generates a simulation execution module 82 reflecting the change result.

  FIG. 12 is a flowchart showing processing up to simulation execution (source code not used) of Web application setting information of the distributed application setting information management function according to the fourth embodiment of the present invention.

Next, the operation of the setting information simulation function 83 that does not use the source code will be described with reference to FIG.
Steps 45A to 76 are the same processing as in FIG. 7, and when the simulation button is pressed on the screen transition information screen (step 76) where the change has been completed, the execution module change function 113 operates. The execution module changing function 113 acquires the annotation information analysis result of the execution module from the setting information analysis function 15 (step 122). Next, the execution module is stopped (step 123). The execution module is backed up (created as a copy) (step 124). Subsequently, change information of the Web application setting information held by the setting information update function 111 is acquired, and the information is written in the execution module copied earlier to be a new execution module. (Step 125). When writing the information, the bytecode of the programming language (for example, JAVA (registered trademark)) describing the Web application 12 is processed while checking the annotation information analysis result already acquired in step 122 and the change information. The writing location is determined and written by a generally available library. Subsequently, the new execution module, that is, the simulation web application 82 is activated (step 126). When it is desired to complete the simulation, a simulation completion button is pressed on the screen transition information screen (step 127). The execution module that has been backed up is restored and activated (step 128).

  According to the fourth embodiment, it is possible to change information set in a distributed manner in a Web application and operate it on a trial basis. In particular, since simulation can be performed even in an environment where there is no source code (such as an on-site environment), failure analysis can be performed quickly.
