Problems solved by technology
[0004] In order to solve the problem that the development of the existing information system lacks logical management between controls, which leads to the need to write a large amount of codes to realize mutual calls between controls, the present invention abstracts a layer of "plug-in" between controls and functional modules, and configures The file defines the logical relationship between plug-ins, uniformly defines and manages the plug-ins, provides a plug-in virtual machine to interpret and execute the configuration file, and reduces the amount of logic code writing between plug-ins

The invention discloses a plug-in virtual machine implementing method. The plug-in virtual machine implementing method includes steps of (1) loading and reading configuration file information by a loading unit, and creating subsystems according to configuration files; (2) loading plug-ins related in the configuration files by a plug-in manager; (3) determining plug-in codes to be executed by a plug-in actuator through a route regulator, transmitting the plug-in codes to the plug-in actuator; and (4) receiving the plug-in codes transmitted by the route regulator by the plug-in actuator and actuating the plug-ins. A layer of 'plug-ins' are abstracted between modules-controls and components, logical relationship among the plug-ins is indicated as configuration files and used for a plug-in virtual machine, the plug-in virtual machine is driven to call the plug-ins in applicable scene and environment, and logics implemented by program codes originally are changed into descriptive text language. Accordingly, writing of a great quantity of codes for logics among controls is omitted, development workload is reduced effectively, and software development cost is reduced as well.
Description
technical field [0001] The invention belongs to the technical field of information systems, and in particular relates to a method for implementing a plug-in virtual machine. Background technique [0002] At present, in the software development of information systems, the level of program reuse is concentrated on the level of "controls". Especially in the development of information systems based on NetWinForm, there is a lack of logical association between controls. Cohesion, the system lacks logical management between controls, and the lack of logical association between controls. At present, enterprise information systems are generally composed of functional modules. Controls are organized in the modules according to business logic and user operation logic to meet customer needs. Therefore, to realize the functional modules of enterprise information systems, it is also necessary to control the logic between controls on the basis of controls. Writing a large number of codes...
