How to get request params as map in Spring controller?

Question

How to get below request params as a map (or any suitable java collection) in spring controller? I want request param 'filter' to be mapped into controller method.

http://example.com/users?filter[0][name]=Dane&filter[1][email]=dane@exm.com

EDIT:

I want something like this in my Rest Controller:

    public void getQueryParams(@RequestParam("filter") Map<String, String> filterValues) {
        //Method body....
    }

Is there a way to achieve this? Appreciate your help. Thanks.

Answer 1

Use a List instead of a Map. The List will contain all values of the parameter 'filter'

public void getQueryParams(@RequestParam("filter") List<String> filterValues) {
    //Method body....
}
