In Spring 4.2 and further releases, there is a first class support for CORS out-of-the-box. The details can be found on this page.

In the Spring classes annotated with RESTController, @CrossOrigin annotation can be used. Following code represents the same:

@CrossOrigin(origins = "http://localhost:3000", maxAge = 3600)
@RestController
public class AngularController {
}

In the above code, localhost:3000 represents Angular app URL.
