Autowiring

I did not find it clear from the docs, so I raise the question here (hope this is the right place):

what is the difference between

Code:

---

        @Autowired
        private MyObj obj;

---

and

Code:

---

        private MyObj obj;

        @Autowired
        public void setObj(MyObj obj)
        {
                this.obj= obj;
        }

---

There is no difference essentially, just personal preference.

thanks.
Is there a case where the 1st example will work and the 2nd might fail? or vice-versa?
