Is it possible to enter code in spring using AOP annotations?

Question

Is it possible to do something like the following:

public void doStuff(@RequirePrivilege("foo") User user) {
    // ...
}

code>

and does it work efficiently as if it were next?

public void doStuff(User user) {
    if(!user.hasPrivilege("foo"))
        throw new UserHasInsufficientPrivileges(); // this is a RuntimeException
    // ...
}

code>

I know that Spring has various kinds of AOP support, but the best I could find was AOP code that was annotated so that it would run before or after a specific method. I want to do the reverse and annotate the code that needs to be changed.

Ultimately, I could just do the above check inside the method, but the way of annotating makes the additional documentation, which makes it obvious that the user needs a certain privilege without having to synchronize the documentation with the code.
