good pratice spring mvc

[mark smith]

hi

i would like to know if there is a web site who list good pratice for spring 3.0?

i started a program, i splitted it with a controller, service and dao layer but i have some question about form objet used in the jsp...

i create a UserForm who is used in a jsp, this object look like

    private SearchCriteria searchCriteria; //information used selected (combobox, textbox)
    private List<String> listCode;   //combobox value (db)
    private List<String> listErreur;
    private List<String> listTypeDeFlux;
    private List<String> listNatureDeclaration;
    private List<String> listVersionDadsu;
    private List<String> listIdCaisse;
    private List<String> listxpediteur;
    private List<String> listOrigine;
    private List<UserInfo> userDataFound;  //db result

i don't know if a good pratice to put all theses information in a object.. or it's better to put all combobox value in a separate object...

example to feed listbox, there are some possibility... call many dao method in the service layer and feed a UserForm object...
or create one methode by list at the service layer and in the controller call all these method..

maybe it's better to create a object only for the listbox... use it a the service layer and controller layer...

at the controller layer, the choice will impact on the @ModelAttribute methode... one for the UserForm or one for every list or one for hypothetical listbox content object...

some basic question, but i prefer the good pratice now than later...

thanks

Personally, I never create a separate Form Domain object, I like to use just the Domain objects I am using up and down the layers. So I will put Lists of values for combo boxes as separate objects I put into the Model.

ok so you put your list of value directely in the model.... and in the controller, you have a @ModelAttribute for every list .... before method.get and method.post the list will be feeded....

No, I only need those lists populated in the Get to send back to the form to display to the user in the drop downs.

Then when they post, it is my domain object that gets passed in, the backing bean of the form, I don't need the lists anymore.

Does that make sense?
