Question

i want to intercept method from a non-proxied object.

I have a class instance MyClass myClassInstance=new MyClass() and i want to intercept call of myClassInstance methods.

I know all works good with proxies, but i need aspect on non proxied.

Is this possible?

Thanks.

Answer 1

It is possible, but it is not desirable.

You can use @Configurable and AspectJ will intercept calls. Read the 7.8.1 Using AspectJ to dependency inject domain objects with Spring section of the docs about it.

In short – AspectJ plugs some “magic” either compile-time or load-time (with a respective weaver), which modifies the classes so that they become part of the spring context.

As of why I think it is undesirable – this is dark magic that happens by modifying the classes’ structure. It’s not an object-oriented approach, and I think it will be hard to support. Imagine 6 months later a colleague of yours is debugging a nasty issue. It could take days before he realizes this magic is happening. This opinion is subjection though. The functionality is there and if you need it – use it.
