ConvertGroup class

An annotation next to @Valid() that checks the nested value with another group: when the outer validation runs group from, the nested value is checked with group to.

Use it when a nested object's rules depend on its owner's situation, for example a car's driver whose licence only matters for the car's checks. Without @Valid() it is a declaration error. Jakarta's @ConvertGroup.

// The ordinary check of a Car checks its driver's DriverChecks rules.
abstract final class DriverChecks {}

@Introspected()
class Car {
  @Valid()
  @ConvertGroup(to: DriverChecks) // from: Default
  Driver? driver;
}

Spring (Java):

@Valid
@ConvertGroup(from = Default.class, to = DriverChecks.class)
private Driver driver;
