Distributed element dependent relationship managing method based on dependent injection

Abstract

The present invention provides a distributed component dependency management method based on dependency injection, belonging to the software component-based technical field. The method comprises the steps as follows: 1) the expansion of CORBA object model; forming a lightweight CORBA component model by defining four states of the component, a dependence injection interface and describing configuration files; 2) the implementing of a component container; implementing a lightweight CORBA component container based on the modification of the core of CORBA ORB; 3) the node management framework of the distributed system; dividing all nodes in a distributed system network to a domain management node and a plurality of non-domain management nodes; with the cooperation of the domain management service and the node management service, realizing the injection management of the distributed dependence among components. The method manages the dependence of the distributed component in a declaration manner rather than in a programming manner. The load of component developers is alleviated, and the flexibility of the system is improved.

Description

technical field [0001] The invention relates to the technical field of software componentization, in particular to a method for managing component dependencies in a distributed componentization system. Background technique [0002] A component is a software entity that can be reused at each stage of the software life cycle. It can be configured and deployed independently, has good encapsulation independence and clearly defined interfaces, and is strictly separated from the running context and other components. The software system developed by component technology can not only effectively improve the developer's efficiency and reduce the developer's cost, but also make the constructed system have good scalability and maintainability. At present, the software development technology based on component technology has been widely concerned by the industry, and has become the mainstream method of software development. [0003] In a traditional structured application system, the e...

Problems solved by technology

These frameworks all have following defects: the one, mostly adopt virtual machine language (Java etc.) and dynamic language implementation (JavaScript etc.) to implement, do not adopt C / C++ language, the efficiency of operation is not high; Dependency injection of objects cannot be applied to distributed component systems

[0005] To sum up, although there are a large number of dependency injection solutions in the industry, they are all based on local dependency management between objects, and there is no distributed dependency management solution based on component systems.
