For example, the model class is as follows: Teacher, Public class teacher {
Private integer ID;
Priavte string name;
Private School;
}
And school, public class school {
Private integer ID;
Priavte string name;
}
The above teacher, school saves the getter and setter methods.
The action class is as follows:
Public class teacheraction extends actionsupport implents modeldriven <teacher> {
Public String saveteacher (){
If (. Teacher. getschool ()! = NULL & teacher. getschool (). GETID ()! = NULL ){
Teacher. setschool (schooldao. Load (teacher. getschool (). GETID ()));
}
Teacher = teacherdao. Save (teacher );
Return success;
}
}
The configuration of this action is as follows:
<Package name = "ajax" extends = "JSON-Default">
<Action name = teacher _ "*" class = "com. zxt. Action. teacheraction method = {1}">
<! -- Set the return type to JSON -->
<Result type = "JSON"> </result>
</Action>
</Package>
The JSP format is as follows:
<% @ Page Language = "Java" contenttype = "text/html; charset = UTF-8" pageencoding = "UTF-8" %>
<! Doctype HTML public "-// W3C // dtd html 4.01 transitional // en" "http://www.w3.org/TR/html4/loose.dtd">
