Design mode 3
In design mode 2 we see, between Entity Bean and Struct
There are many duplicate code, such as the same field declaration (corresponding to the table columns in the database).
If you let the Entity Bean inherited from the structure to avoid redundant code. but
This design still cannot display the connection between Beans.
Code Snippet for Company Entity Bean
Public Class CompanyBean Extends CompanyStruct
Implements EntityBean {
EntityContext EntityContext;
// All Fields in CompanyStruct Are Available for CMP
Public Integer Ejbcreate (Companystruct Struct)
Throws createException {
this.comid = Struct.comID; // SET The PRIMARY Key
SetData (STRUCT); // This Removes Some Redundant Code
Return NULL;
}
The rest of the code, such as the implementation and design mode of GetData () and setData () methods 2
It is exactly the same.
