How to validate an method argument with @Validated annotation based on group

Question

I have an entity XYZ.java

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@ToString
public class XYZ extends BaseEntity implements Serializable {

  @NotNull (groups = {Groups.Insert.class, Groups.Delete.class, Groups.Update.class, Groups.Select.class})
  private String X;

and there is an interface XYZCRUD.javato do CRUD operations on XYZ.java

@Validated
public interface XYZCRUD {

  public int insert(@Valid XYZ entity) throws SomeException;

Although javax's @Valid works for @NotNull validation but it does not support passing validation group as annotation attribute from the method from where i am triggering the validation . So I tried using @Validated annotation which does allow to pass groups via an attribute "value" like this

@Validated
public interface XYZCRUD {

      public int insert(@Validated(value=SomeGroup.class) XYZ entity) throws SomeException;

However it does not trigger the validation at all.I tried after removing the groups attribute from the field and also from the trigger annotation.

Conclusion : @Validated does not trigger @NotNull

Questions :

1. Why @Validated does not trigger the javax's @NotNull ? Am I doing something wrong or does it not support it?
2. Is there any any other way? cannot implement custom validator

NOTE : I am also using lombok if it has something to do with this.

@mayank-vats If you want to apply a group to specific method (not all public methods), you can use:

@Validated
public class MyClass {

    @Validated({Group1.class})
    public myMethod1(@Valid Foo foo) { ... }

    @Validated({Group2.class})
    public myMethod2(@Valid Foo foo) { ... }

    ...
}
