@Target(value={METHOD,FIELD}) @Retention(value=RUNTIME) public @interface TargetAggregateIdentifier
Field or method level annotation that marks a field or method providing the identifier of the aggregate that a command targets.
If placed on a method, that method must contain no parameters. The return value will be used as the Aggregate Identifier. If placed on a field, the field's value will be converted into an AggregateIdentifier instance identical to how a method's return value is converted.
