A device for component model and component factory supporting dynamic configuration

Abstract

The invention discloses a component model supporting dynamic configuration and a component factory device. The component includes a business interface, a component body and a management shell; wherein, the component body is used to contain sub-components; the management shell provides a meta-interface supporting dynamic configuration. Under the Java platform, the component factory instantiates components based on the architecture description, including: meta-interface implementation framework, ADL parser, bytecode dynamic generator and class dynamic loader. Among them, the meta-interface implementation framework provides a dynamic configuration method based on the architecture, including: the life cycle coordinator switches the component from the running state to the relatively static security configuration state; during the security period, the member manager is used to add, Delete or update sub-components, and bind connectors are used to dynamically adjust the connection relationship between component interfaces. The invention enables the third party to configure its system structure online through the component meta-interface, which can effectively improve the dynamic expansibility of the system in the running stage.

Description

[0001] The patent application of the present invention claims the priority of the earlier Chinese application with the filing date of 20110913 and the application number of 201110270377.5. technical field [0002] The invention relates to the technical field of computer software, in particular to a component model and component factory supporting dynamic configuration. Background technique [0003] As the Internet becomes the mainstream operating platform, while the software presents a component-based service architecture, the dynamic changes of the context (computing context, environmental context, and user context) during its operating period make the software itself have to "evolve" in response to these changes. sex" adjustment. It can be seen that "evolution" is the most expensive activity in the software life cycle. It is supported by the efficient mechanism of the software infrastructure framework, and the software system dynamically adjusts the configuration compositi...

Problems solved by technology

The methods adopted mainly include: large expansion of the original component computing platform, developers write a large number of codes dealing with the dynamic characteristics of the system under the distributed component management framework, which is heavy burden and high complexity; relying on the dynamic configuration provided by the platform A large number of reflection elements such as structure and semantic metadata are required to realize the dynamic configuration of applications, but the reflection ability of the component platform is high; relying on the special control of the component container to improve the online evolution ability of the system, but it is also necessary to control the container. expand

Therefore, the existing component-based software systems need to pay a large additional price in order to realize dynamic configuration
