Question

@RequestMapping(value=\"/map/update\", method=RequestMethod.POST, produces = \"application/json; charset=utf-8\")

Answer 1

@Paul Strack's great solution mixed with Lombok magic:

@Data
public class ValidList implements List {
    @Valid
    @Delegate
    private List list = new ArrayList<>();
}

Usage (swap List for ValidList):

public ResponseEntityWrapper updateMapTheme(
        @RequestBody @Valid ValidList categories, ...)

(Needs Lombok, but if you don't use it already you really want to try it out)
