title: When to use @Pointcut & @Before, @After AOP Annotations
body: <p>Am learning AOP concepts in Spring. I am now pretty aware of the usages of <code>@Before</code> and <code>@After</code> Annotations and started using it for Time capturing purpose.</p>
  
  <p>This is pretty much satisfying all my AOP related needs. Wondering what is that <code>@pointcut</code> annotation that every spring guide talks about ? Is that a redundant functionality ? or does it has separate needs ? </p>
