Question

Is it possible to grab various form components and turn them into their corresponding DAO objects? I’m trying to avoid creating a custom Bean (which encapsulates all fields) for each Form.

Ex:

<form action="/add">
  <input name="foo" id="foo" value="29"/>
  <input name="bar" id="bar" value="63"/>
</form>


public void add(@ModelAttribute("foo") Foo myFoo, @ModelAttribute("bar") Bar myBar)

Currently, I’d have to use the HttpRequest, extract the values (29,63), and use them as primary keys to look up the correct database objects. I didn’t know if there was a quick way to auto-wire this using ModelAttribute.

Thanks!

You should use @RequestParam

public void add(@RequestParam("foo") Foo myFoo, @RequestParam("bar") Bar myBar) {
}
