3,controller


@Controller
@RequestMapping("/tc")
public class TestController {
	
	@Autowired
	TestService testService;
	
	@RequestMapping("tm")
	public String test(ModelMap map) {
		System.out.println("Hello world");
		return "test";
	}
	
	@RequestMapping("spring")
	public String spring(ModelMap map) {
		System.out.println("Hello Spring");
		return testService.getView();
	}
}

4 service

@Service
public class TestServiceImpl implements TestService{

    @Override
    public String getView() {
        return "spring";
    }

}

test.jsp

<body>
<h2>Hello World!Test</h2>
<a href="spring">Spring</a>
