@Validated should allow ElementType.METHOD target [SPR-9174]

[spring-projects-issues]

Dejan Predovic opened SPR-9174 and commented

@Validated is, at the moment, the only place where one can set a validation group for method-level validation, but different methods of the class typically need different validation groups. Imo, @Validated should work exactly like @Transactional - class level definition is fine, but one needs to be able to override it at the method level.

I 100% agree, I just spent a few hours digging around for this feature because I just assumed that it must be present.
The documentation insinuates that you can control method level validation groups with @Validated.
For that to work properly, we really need @Validated to allow ElementType.METHOD.

Spring-driven method validation supports an @Validated annotation at the method level now, with validation hints at that level overriding any class-level specifications. Composing custom annotations, using @Validated as a meta-annotation, works at both levels as well.

Note that an @Validated marker at the class level is nevertheless necessary to trigger method validation for a specific bean to begin with. Method-level use basically just allows for overriding validation groups.
