4.5. Injecting AspectJ aspects

Although Spring AOP is sufficient for many applications of aspects, it’s a weak AOP solution when contrasted with AspectJ. AspectJ offers many types of pointcuts that aren’t possible with Spring AOP.

Constructor pointcuts, for example, are convenient when you need to apply advice upon the creation of an object. Unlike constructors in some other object-oriented languages, Java constructors are different from normal methods. This makes Spring’s proxy-based AOP woefully inadequate for advising creation of an object.
