A module dynamic loading method and device

Abstract

The invention discloses a dynamic module loading method and device. The method comprises the following steps: when requiring to dynamically load an application module, establishing a new servlet service object; when receiving a servlet request, forwarding the received servlet request to a new servlet service object by using the original servlet service object to dynamically load the application module by the new servlet service object; and after the new service object is established, destroying the servlet service object established during last dynamic module loading. By the method disclosed by the invention, a project framework does not need to be established again, when the application module is loaded dynamically every time, only the new servlet service object needs to be established, therefore, dynamic loading to modules can still be realized under the condition that the project framework is not changed, the dynamic module loading method is easy to realized, moreover, learning cost is low, and consumed labor and time are less.

Description

technical field [0001] The invention relates to the technical field of module loading, and more specifically, to a method and device for dynamically loading modules. Background technique [0002] In java web applications, there are usually many B / S applications that need to run continuously for a long time. Sometimes these applications need to add or delete some application modules. Next, dynamically add or delete application modules. [0003] At present, the commonly used module dynamic loading technology is OSGi technology, which is a series of specifications of Java dynamic modular system and the technical implementation based on this specification, which is a more fine-grained module dynamic loading technology. Although OSGi technology can realize the dynamic loading of application modules, when a project does not use OSGi technology in the architecture, and the module dynamic loading requirements are added during the project development process (such as the dynamic loa...

Problems solved by technology

Although OSGi technology can realize the dynamic loading of application modules, when a project does not adopt OSGi technology in the architecture, and the module dynamic loading requirements are added during the project development process (such as the dynamic loading requirements for MVC modules), it may be Need to rebuild the project architecture

Due to the high complexity of OSGi technology, rebuilding the project architecture will inevitably lead to increased learning costs, and will also consume more manpower and time
