List as form backing object using Spring 3 MVC, correct syntax?

Question

I want to do something like this, where Foo is a class with one String field name, and getter/setter:

Answer 1

Maybe this answersyour question:

CONTROLLER :

@Controller("/")
public class FooController{

    //returns the ModelAttribute fooListWrapper with the view fooForm
    @RequestMapping(value = "/FOO", method = RequestMethod.GET)
    public String getFooForm(Model model) {
        FooListWrapper fooListWrapper = new FooListWrapper();
        fooListWrapper.add(new Foo());
        fooListWrapper.add(new Foo());

        //add as many FOO you need

        model.addAttribute("fooListWrapper", fooListWrapper);

        return "fooForm";
    }

    @RequestMapping(value = "/FOO", method = RequestMethod.POST)
    public String postFooList(@ModelAttribute("fooListWrapper")FooListWrapper fooListWrapper, Model model) {

        //...........
    }

}

FOO LIST WRAPPER :

public class FooListWrapper {
    private List fooList;

    public FooListWrapper() {
         this.fooList = new ArrayList();
    }

    public List getFooList() {
        return fooList;
    }

    public void setFooList(List fooList) {
        this.fooList = fooList;
    }

    public void add(Foo foo) {
        this.fooList.add(foo);
    }
}

FOO CLASS :

public class Foo {
    private String name;

    public Foo() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

JSP VIEW (name = fooForm):
