Method and device for realizing hot plugging of application components

Abstract

The invention discloses a method and a device for realizing the hot plugging of application components. The method comprises the steps: a weak dependency component is mirrored into a memory, when theweak dependency component is updated, the updated weak dependency component is mirrored into the memory once again so as to obtain an updated corresponding mirror component, and when the weak dependency component needs to be invoked, the corresponding mirror component thereof is invoked; a strong dependency component is divided into different component groups according to the mutual dependency relationship thereof, different component groups are loaded to different application domains, when one strong dependency component is updated, the application domain corresponding to the component groupin which the strong dependency component is present is unloaded and the component group in which the updated strong dependency component is present is loaded into the newly-established application domain, and when the strong dependency component needs to be invoked, the strong dependency component is invoked in the application domain corresponding thereto. The technical solution of the method canimplement the hot plugging on the application components and, unlike the prior art, has no need of not only restarting IIS, but also interrupting the operation from a client.

Description

technical field [0001] The invention relates to the technical field of WEB management systems, in particular to a method and device for realizing hot plugging of application components. Background technique [0002] In a large-scale Internet information service (IIS, Internet Information Server)-based WEB management system developed using .net technology, there will be thousands of application components. For these application components, there is a need for dynamic updates. For example, in the process of development and testing of the IIS-based WEB management system, developers or testers need to frequently update application components for testing and verification when using the WEB server; (such as in large-scale commercial, financial securities and other websites), the application components need to be updated. [0003] But in the existing solution, IIS must be restarted to update the application components. When restarting IIS, all components need to be reloaded, so ...

AI Technical Summary

Problems solved by technology

[0003] But in the existing solution, IIS must be restarted to update the application components

When restarting IIS, all components need to be reloaded, so the startup process is relatively slow, and it will take a certain amount of time to restore to the original operation interface and enter the corresponding test or verification data

In addition, in the application that the client needs to run continuously, restarting IIS will interrupt all the operations currently running on the client
