Spring form ModelAttribute List binding

Question

There are way to bind List object by using spring modelAttribute? Actually, I know that it can be done by using Wrapper class having list member variable. like this

Dto :

public class SampleDto {

    private List<SubSampleDto> sampleList;
}

Controller :

@RequestMapping(value = "/sample/insert.ajax")
    public String set(@ModelAttribute("sampleDto") SampleDto dto) {
      ...
    }

But, I want to know the way not to use wrapper class. Thanks

Answer 1

You could bind it like,

@ModelAttribute("sampleList")
public List<SubSampleDto> getAll() {
return subSampleDtoService.getAll(); //or something to get SubSampleDto list
}

if i understood you correctly
