Problem polega na tym, że gdy przez kontroler AngularJS pobieram dane z linku http://rest-service.guides.spring.io/greeting (link z dokumentacji Springa, wystawia po prostu JSONa z polami ID i content) wszystko działa i wyświetla się jak powinno (The ID is 1), gdy chce odebrać zasoby ze swojego linku http://localhost:8080/greeting nie wyświetla się nic (The ID is - i to wszystko). Proszę o jakąś wskazówkę.

@RestController
public class EmpController {
	
	 private static final String template = "Hello, %s!";
	 private final AtomicLong counter = new AtomicLong();

	    @RequestMapping("/greeting")
	    public Greeting greeting(@RequestParam(required=false, defaultValue="World") String name) {
	        System.out.println("==== in greeting ====");
	        return new Greeting(counter.incrementAndGet(), String.format(template, name));
	    }

}

public class Greeting {
	private final long id;
    private final String content;

    public Greeting() {
        this.id = -1;
        this.content = "";
    }

    public Greeting(long id, String content) {
        this.id = id;
        this.content = content;
    }

    public long getId() {
        return id;
    }

    public String getContent() {
        return content;
    }

}
