Allow custom @Validated annotations for handler method parameters [SPR-12406]

[spring-projects-issues]

Vadim opened SPR-12406 and commented

Extend @Validated with Target.Annotation allowing the creation of custom @Validated annotations.

The result will be:
public boolean registerNewUser(@RegisterValid @RequestBody User newUser) {

instead of

public boolean registerNewUser(@Validated({Default.class, RegisterGroup.class,VIP.class....}) @RequestBody User newUser) {

Affects: 4.0.7, 4.1.1

Declaring custom @Validated annotations works already, since the TYPE argument includes ANNOTATION_TYPE anyway. Using such custom validating annotations at the type level, e.g. for method validation, works as well. However, the check at the handler method parameter level seems to be too restrictive; I'll revise this for 4.1.3, finally closing that gap.

Resolved through an explicit meta-annotation lookup for @Validated in all applicable places. This will be available in the next 4.1.3 snapshot; feel free to give it an early try...
