Embodiment 1
[0053] figure 1 It is a flow chart of the business data query method provided in Embodiment 1 of the present invention. According to different requirements, the execution sequence in the flowchart can be changed, and some steps can be omitted.
[0054] Step S1, establishing database connection pools corresponding to multiple application systems.
[0055] The basic principle of the database connection pool is to maintain a certain number of database connections in the internal object pool, and expose methods for acquiring and returning database connections to the outside. For example, external users can obtain the connection through the getConnection method, and then return the connection through the releaseConnection method after use. Note that the connection is not closed at this time, but is recycled by the connection pool manager and prepared for the next use. Specifically include steps:
[0056] a. Create a ConnectionPool instance, and initialize and create a preset val...
Embodiment 2
[0104] Figure 4 It is a functional module diagram in a preferred embodiment of the service data query device of the present invention.
[0105] In some embodiments, the service data query device 40 runs in an electronic device. The service data query device 40 may include a plurality of functional modules composed of program code segments. The program codes of each program segment in the service data query device 40 can be stored in a memory, and executed by at least one processor to execute (see for details figure 1 and related descriptions) business data query.
[0106] In this embodiment, the service data query device 40 can be divided into multiple functional modules according to the functions it performs. The functional modules may include: a building module 401 , a receiving module 402 , a query module 403 and a display module 404 . The module referred to in the present invention refers to a series of computer program segments that can be executed by at least one pr...
Embodiment 3
[0156] Figure 5 It is a schematic diagram of the electronic device provided by Embodiment 3 of the present invention.
[0157] The electronic device 5 includes: a memory 51 , at least one processor 52 , a computer program 53 stored in the memory 51 and operable on the at least one processor 52 , and at least one communication bus 54 .
[0158] When the at least one processor 52 executes the computer program 53, the steps in the above embodiments of the service data query method are realized.
[0159] Exemplarily, the computer program 53 may be divided into one or more modules / units, and the one or more modules / units are stored in the memory 51 and executed by the at least one processor 52, To complete the present invention. The one or more modules / units may be a series of computer program instruction segments capable of accomplishing specific functions, and the instruction segments are used to describe the execution process of the computer program 53 in the electronic devic...
