Problems solved by technology

[0009] In summary, the inventor found that although the existing Spring dependency injection function is relatively powerful, it cannot dynamically change the injected feature instances when the system is running, and is not suitable for business systems with a large number of business features, and its practicability is low.

Abstract

An embodiment of the invention discloses a dependency injection method, which includes the steps: acquiring configuration information of a business feature from a business feature configuration table according to the business feature required by system running; acquiring configuration information of a corresponding feature instance from a feature instance configuration table according to the configuration information of the business feature and the mapping relation between the default business feature configuration table and the feature instance configuration table; and instancing the business feature according to the acquired configuration information of the feature instance, and returning the instanced feature to a system for running. The embodiment of the invention further discloses a dependency injection device based on system running. By the aid of the method and the device, the injected feature instance can be dynamically changed when the system runs, so that the loose coupling relation between the system (invoker) and the feature instance (implementation class) is guaranteed, and practicality of Spring dependency injection is improved.

Description

technical field [0001] The present invention relates to the technical field of dependency injection, in particular to a system operation-based dependency injection method and device. Background technique [0002] Dependency Injection (Dependency Injection, DI), also known as Inversion of Control (IoC), is an important technology that uses the principles of object-oriented programming to reduce the coupling problem of computer programs. Dependency injection technology is mainly represented by the Spring framework (an open source Java / Java EE full-stack (full-stack) application framework). The Spring framework provides three dependency injection methods: attribute injection, constructor injection and factory method injection. . Spring's dependency injection technology uses XML (Extensible Markup Language, Extensible Markup Language) configuration files or Java annotations for injection configuration. Among them, XML configuration files are used for injection configuration, an...
