Why applying Spring Transactional annotation on the concrete class or its methods is recommended rater than on interface?

Spring recommends annotating concrete classes and its methods with the @Transactional annotation, as opposed to annotating interfaces.

You can place the @Transactional annotation on an interface (or an interface method), but this works only if you are using interface-based proxies.

Java annotations are not inherited from interfaces means that if you are using class-based proxies ( proxy-target-class="true") or the weaving-based aspect ( mode="aspectj"), then the transaction settings are not recognized by the proxying and weaving infrastructure, and the object will not be wrapped in a transactional proxy.
