How to bind a list of object to SpringMvc Controller?

Question

I\'m using the following action on a SpringMvc application:

@RequestMapping(value = \"/test\", method = RequestMethod.GET)
public ModelAndView test(
    @Mod

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
