How can I make use of a method that is part of a restcontroller in java code?

Question

For e.g. when I try to invoke the following method which is part of PersonController

@RequestMapping("/selectnamelbyid")     
public Template selectNamesbyID(@RequestParam(value = "id") String id) {...

using the code below

PersonController personController = new PersonController();
personController.selectNamesbyID(id);

it throws a nullpointer. I am trying to centralize the data fetching logic to the controller class by doing this. Can someone tell what am I doing wrong?

You need to post more code and/or the exception for this to be answerable. — mvd, Oct 27 '15 at 02:25
IoC - don't call me, I'll call you -- and nobody else can call you either :) — ZhongYu, Oct 27 '15 at 02:29
Keep your data fetching logic into service layer and use that service in multiple controllers. — 2787184, Oct 27 '15 at 02:31
@ravi that is a good idea. Should have thought about that before. — sarego, Oct 27 '15 at 02:40

I believe PersonController should be initialized by spring container. It can be injected into your code somewhere but it will not work if you new this instance manually.
