How to validate @RequestMapping requests by condition?

Question

I'm using hibernate validations for validating incoming requests in spring @RestController.

Problem: I want to reuse the same DTO object in multiple endpoints. But validate some fields only by condition (eg only on specific endpoints).

@RestController
public class ProductsServlet {
    @GetMapping("/avail/product")
    public Object avail(@Valid ProductDTO product) {
        //should validate id field only
    }       

    @GetMapping("/sell/product")
    public Object sell(@Valid(with = GroupFuture.class) ProductDTO product) {
        //should validate id + from field
    }       
}

public class ProductDTO {
    @NotNull
    @NotBlank
    private String id;

    @Future(groups = GroupFuture.class)
    private Date from;
}

Of course the @Valid(with = GroupFuture.class) statement is invalid. But it shows what I'm trying to achieve.

Is that possible?

Got it. Also having to use the Default.class group to validate any fields not having a group.

@GetMapping("/sell/product")
public Object sell(@Validated({Default.class, GroupFuture.class}) ProductDTO product) {
}
