Embodiment 1
[0026] figure 1 It shows the implementation process of the dynamic construction function operation method provided by Embodiment 1 of the present invention. According to the defined operation metadata entity interface, the method flexibly configures the corresponding function menu, thereby realizing the dynamic construction of function operation and enhancing the system function operation. The scalability, the detailed steps are as follows:
[0027] In step S101, an operation type is preset, and the preset operation type is registered in a database or a configuration file, and the preset operation type includes a predefined operation metadata entity interface and an implementation operation type.
[0028] In the embodiment of the present invention, the defined operation metadata entity interface is as figure 2 As shown, the operation metadata entity interface includes but not limited to attributes such as operation metadata entity (FormOperation) and view information (View),...
Embodiment 2
[0062] Figure 5 It shows the implementation process of the dynamic construction function operation method provided by the second embodiment of the present invention. This embodiment is in figure 1 On the basis of , step S501 is added to define an operation metadata entity. Metadata refers to the data used to define data, and is used to describe the specific information of functional operations. By defining and operating metadata entities, the unification of the same type of operation is realized. Such as Figure 6 As shown, the defined operational metadata entities include but are not limited to the following attributes:
[0063] After Actions: Business services that can be executed after the operation is executed;
[0064] Business service before operation (BeforeAction): that is, the business service that can be executed before the operation is executed;
[0065] Available states for this operation (EnabledStates): it can be used in the current state;
[0066] Operatio...
