Method and system for changing program data source based on Redis

Abstract

The invention provides a method and a system for changing a program data source based on Redis, and the method comprises the steps: writing a preset first data source into a data source pool module composed of Redis when a program is started; when the program runs, acquiring annotation information, and storing a second data source specified by the annotation information into a data source switching module through a Spring component; and the data source switching module is used for reading in the first data source, taking out the second data source required by the program from the data source pool module and injecting the second data source into the corresponding thread of the program. Based on the method, the invention further provides a system for changing the program data source, processing equipment and a storage medium. Data source management is performed on multiple data sources of the application program by utilizing Redis, and corresponding change is performed according to the specified data source of the program. Developers can conveniently and dynamically modify program data source settings, data source configuration can be dynamically adjusted when a program runs, and theeffect of modifying the running program in real time is achieved.

Description

technical field [0001] The invention relates to the technical field of software development, in particular to a method and system for changing program data sources based on Redis. Background technique [0002] In order to improve the efficiency of applications accessing data sources, the operation of separating reads and writes is generally performed in applications, which requires different data sources for applications and dynamic switching of data sources. For applications with multiple data sources, it is more necessary to accurately change to the corresponding data source for database operations. For a running program, if the data source information needs to be modified, the application program needs to be stopped and the data source reconfigured, which will affect the normal operation of the application system. Generally, applications can only store data sources in memory, and cannot share data sources with other applications. [0003] The existing technical solution...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing technology is that the data source is managed through the configuration file, which is generally a single data source. If a new data source needs to be added or the data source needs to be changed, the program code needs to be modified, which increases the code maintenance cost; if The program is running and needs to be restarted, which affects the normal operation of the program

The data source in the prior art can only be used in this application system, and the data source cannot be shared with other applications, which restricts the diversity of program access data
