I'm using the following action on a SpringMvc application:
@RequestMapping(value = "/test", method = RequestMethod.GET)
public ModelAndView test(
@ModelAttribute List<Group> groups
) {
//return whatever
}
My Group class has an 'id' and a 'name' property. Default getter/setter. How should i call this action in order to have this list correctly instanciated?
I tried something like:
/test?groups.id=2&groups.name=stackrocks&groups.id=3&groups.name=stackrules
Didn't work.
Also tried:
/test?groups[].id=2&groups[].name=stackrocks&groups[].id=3&groups[].name=stackrules
No success.
So, how to bind a list when using SpringMvc?
You can't bind parameters of method with the exactly that signature. @ModelAttribute
binds attributes to the fields of the corresponding model object, so you can encapsulate your List
into object:
public class Groups {
private List<Group> list = new AutoPopulatingList<Group>(Group.class);
...
}
@RequestMapping(value = "/test", method = RequestMethod.GET)
public ModelAndView test(
@ModelAttribute Groups groups
) {
//return whatever
}
and then call it as follows:
/test?list[0].id=2&list[0].name=stackrocks&list[1].id=3&list[1].name=stackrules
