Question

Having this http://myserver/find-by-phones?phone=123&phone=345 request, is it possible to handle with something like this:

@Controller
public class Controller{
    @RequestMapping("/find-by-phones")
    public String find(List<String> phones){
       ...
    }
}

Can Spring MVC some how convert multi-value param phones to a list of Strings (or other objects?

Thanks.

Alex

Answer 1

“Arrays” in @RequestParam are used for binding several parameters of the same name:

phone=val1&phone=val2&phone=val3

–

public String method(@RequestParam(value="phone") String[] phoneArray){
    ....
}

You can then convert it into a list using Arrays.asList(..) method

EDIT1:

As suggested by emdadul, latest version of spring can do like below as well:

public String method(@RequestParam(value="phone", required=false) List<String> phones){
    ....
}
