Description

  The present invention relates to an information processing apparatus, an information processing method, and an information processing program.

  There is an information processing system in which various business programs are used by a plurality of customers (see, for example, Patent Document 1). For example, there is a form in which a plurality of customers commonly use various programs (program groups) for operating a virtual store for electronic commerce, and each customer appears to operate their own system in appearance. . In this case, the program development side has the advantage of being able to stably recover the enormous development costs required for the development of a large-scale system, and the user side can also install the system at a reasonable cost according to the degree of use. There is an advantage that it can be constructed.

  Various business programs provided by the information processing system are created so that they can be used as they are as much as possible. However, depending on the customer, exceptional processing is often desired. For example, the program part that checks whether or not the telephone number of the product purchaser is appropriate is generally in a format where the area code, area code, and number are separated by "-". Generally, it is made so as to allow even a format in which "-" is mixed. However, some customers may want to make an error when “-” is included in addition to numbers.

  Conventionally, in order to cope with such exceptional processing, a method of overriding the processing of the program on the main body with newly defined processing is used. In the scene where the overridden process is executed, the overridden process is actually executed. However, when using the override method, the program must be written in the main system. For example, when the main body is described in Java (registered trademark), the overriding process needs to be described in Java in the main body.

JP 2013-33449 A

  As described above, in an information processing system in which various business programs are used by a plurality of customers, if processing different from the standard business program of the main body is to be performed, it is necessary to perform processing override. There was a problem that the same programming language had to be used and the degree of freedom was low. Some customers may make their own modifications, but if the program assets they already own are in a different programming language or the programming language they are used to is different, it can be easily handled. Can not.

  The present invention has been proposed in view of the above-described conventional problems, and an object thereof is to facilitate exceptional processing in an information processing system in which various business programs are used by a plurality of customers. It is to be able to introduce.

  In order to solve the above problems, in the present invention, means for determining whether or not an annotation description specifying an application program interface name is included in the processing to be executed in the standard program, and the annotation description If the application program interface name is determined to be included, the database that associates the application program interface name with the call address of the application program interface is referred to, and the call address corresponding to the application program interface name specified by the annotation is obtained. Means, means for transmitting a processing request to the acquired call address, receiving the processing result, and means for reflecting the received processing result in the processing result of the standard program.

  In the present invention, exceptional processing can be easily introduced in an information processing system in which various business programs are used by a plurality of customers.

FIG. 1 is a diagram showing a configuration example of a system according to an embodiment of the present invention. In FIG. 1, an information processing apparatus 1 that provides an information service in which various business programs are allocated to a plurality of customers for use by a tenant is connected to a network 2 such as the Internet. The network 2 is also connected to an information processing device 3 under the management of the customer and an information processing device (terminal device) 4 used by a general user who accesses an e-commerce virtual store operated by the customer. .

  In addition to basic software such as an OS (Operating System), the information processing apparatus 1 includes a basic program 11 having a function of managing a plurality of customers, a standard program (business program) 12 such as EC (Electronic Commerce) logic, and the like. Is held. The basic program 11 and the standard program 12 are described in a programming language such as Java, and include a source program and a binary code. In the standard program 12, an API (Application Program Interface) annotation indicating that there is a possibility of substitution for exceptional processing in units of processing (function or the like) is added.

  FIG. 2 shows a state where an API annotation is added to the standard program 12. The actual description format of the API annotation differs depending on the installed program, but includes at least a description for identifying the API annotation and the API name of the call destination. In FIG. 2, the part surrounded by @Customizable is an API annotation, and the process that is subject to public boolean check () throws SQLException below. Note that the API annotation is added to the source program, but the binary code obtained by compiling the source program also includes the API annotation.

  Returning to FIG. 1, the information processing apparatus 1 includes a main body initialization unit 13 that initializes the main body system based on the basic program 11 and the standard program 12 and constructs the main body system area 14. The main system area 14 includes a main system function execution unit 141 that executes a function as the main system, and main system data 142 unique to the main system.

The tenant system area 16 includes a processing calling unit 161 that calls the standard program 12 in response to a general user or administrator's access to a virtual store for electronic commerce operated by a customer, tenant specific data 162 unique to the tenant system, And an API / OUT table 163 that holds API information corresponding to API annotations of the standard program 12.

  FIG. 3 is a diagram showing an example of the data structure of the API / OUT table 163, which includes “name (NAME)”, “address (URL)”, and “application ID (APP_ID)”. “NAME” is an API name with “/ before” and “/ after” indicating pre-processing or post-processing. For example, when the API name is “admin / member / check”, it becomes “admin / member / check / before” when performing pre-processing, and “admin / member / check / after” when performing post-processing. Become. The “address (URL)” is a URL (Uniform Resource Locator) that is a call destination of the corresponding API. “Application ID (APP_ID)” is information for identifying an application having a corresponding API. The application registered here may be the application 19 in the information processing apparatus 1 or may be an application held in the external information processing apparatus 3 or the like connected to the network. If the operator of the tenant system wants to perform processing different from the standard, the API information of the application is registered in advance in the API / OUT table 163 in correspondence with the API annotation attached to the processing.

  Returning to FIG. 1, the information processing apparatus 1 further includes a program execution unit 17 and an API calling unit 18. The program execution unit 17 executes the standard program 12 in response to a call from the process call unit 161 in each tenant system area 16. The API calling unit 18 refers to the API / OUT table 163 when executing the processing with the API annotation added when executing the program by the program executing unit 17, and when the corresponding API information is registered, It has a function to call the corresponding API.

Further, the information processing apparatus 1 and the like include a monitor 110, a keyboard 111, a mouse 112, and the like connected to the I / O 107. A CD / DVD (Compact Disk / Digital Versatile Disk) drive or the like can be connected to the I / O 107.

  The functions of the information processing apparatus 1 and the like described in FIG. 1 are realized by executing a predetermined program in the CPU 102. The program may be acquired via a recording medium, may be acquired via a network, or may be embedded in a ROM.

<Operation>
5 and 6 are flowcharts showing an example of processing of the above embodiment. First, in FIG. 5, when a process is called by the process call unit 161 of any tenant system and the process is started, the API call unit 18 adds a predetermined API annotation to the process to be executed in the standard program 12. Is determined (step S101).

  If it is determined that the API annotation is not added to the process to be executed (No in step S101), the program execution unit 17 executes the corresponding process from the standard program 12 (step S102). Is obtained (step S103), the process result is returned to the caller (step S104), and the process is terminated.

  If it is determined that an API annotation has been added to the process to be executed (Yes in step S101), the API calling unit 18 analyzes the annotation information from the API annotation and extracts an API name (step S101). S105).

  Next, the API calling unit 18 determines whether or not the extracted API name is registered as a prior API call in the API / OUT table 163 as a database (step S106). That is, it is determined whether or not a name starting with a character string obtained by adding “/ before” to the extracted API name in “NAME” of the API / OUT table 163 shown in FIG.

  If it is determined that the API name is registered in the API / OUT table 163 as a pre-API call (Yes in step S106), the API calling unit 18 reads application information from the API / OUT table 163, that is, an address (URL) or the like. Is acquired (step S107), the API is called, and a response is acquired (step S108).

  Next, the API calling unit 18 analyzes the API response (step S109), and determines whether or not a processing result exists in the API response (step S110).

  When it is determined that the processing result exists in the API response (Yes in step S110), the API calling unit 18 outputs the processing result acquired from the API as the processing result of the standard program 12 (step S111). The process is returned to the caller process call unit 161 (step S112), and the process ends. That is, when the processing result is obtained by the pre-processing API, only the pre-processing API is executed and the process is terminated.

  On the other hand, when it is determined that the API name is not registered as a pre-API call in the API / OUT table 163 (No in step S106), or when it is determined that there is no processing result in the API response (No in step S110). ) Shifts to the processing of FIG. That is, the program execution unit 17 executes a corresponding process from the standard program 12 (step S113) and acquires a standard process result (step S114).

  Next, the API calling unit 18 determines whether or not the API name extracted from the API annotation is registered as a post API call in the API / OUT table 163 as a database (step S115). That is, it is determined whether or not a name starting with a character string obtained by adding “/ after” to the extracted API name in “NAME” of the API / OUT table 163 shown in FIG.

  If it is determined that the API name is registered as a post API call in the API / OUT table 163 (Yes in step S115), the API call unit 18 reads application information from the API / OUT table 163, that is, an address (URL) or the like. Is acquired (step S116), the API is called, and a response is acquired (step S117).

  Next, the API calling unit 18 analyzes the API response (step S118), and determines whether or not a processing result exists in the API response (step S119).

  When it is determined that the processing result exists in the API response (Yes in step S119), the API calling unit 18 overwrites the processing result acquired from the API with the processing result of the standard program 12 (step S120), and the processing result is displayed. The process is returned to the caller process call unit 161 (step S121), and the process ends.

  On the other hand, if it is determined that the API name is not registered in the API / OUT table 163 as a post API call (No in step S115), or if it is determined that there is no processing result in the API response (No in step S119) ) Returns the processing result of the standard program 12 to the caller (step S122), and ends the processing.

  FIG. 7 is a diagram illustrating an example of calling an API, and illustrates an example of processing for checking whether or not registration of product buyer information is possible. As a premise, the corresponding processing by the standard program 12 allows a format in which numbers and “-” are mixed for a telephone number, whereas the API to be replaced allows a case where “-” is included in addition to numbers. Not to do.

  FIG. 7A shows an example of information of the purchaser of the product to be checked. “TEL” in the third to fourth lines from the last is “090-1111-1111”, and “− "It is included. FIG. 7B shows a processing result by the standard program 12, and “TRUE” (registration is possible) is returned. On the other hand, FIG. 7C shows an example of the processing result by the API call. The message “-cannot be entered in the telephone number” is returned, and “FALSE” (registration rejected) is returned as the check result. Has been.

  This API process may be performed before or after the standard program 12. If it is performed before, processing by the standard program 12 is not performed. When performing later, the processing result by the standard program 12 is overwritten by the processing result by the API.

  Although an example of an API that returns a processing result has been described, for an API that does not return a processing result, the state of the tenant system or the like can be changed in the process called by the API, and before the target process Alternatively, by executing it later (both before and after), the behavior of the subsequent processing can be corrected.
