import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/springtest")
public class SpringMVCController {

    @RequestMapping(value="/redirectTest", method = RequestMethod.GET)
    public String redirectTest() {
        //some stuff here
        return "redirect:/springtest/redirectedUrl";
    }

    @RequestMapping(value="/redirectedUrl", method = RequestMethod.GET)
    public String redirection(Model model) {
        //some stuff here
    	model.addAttribute("msg", "Spring Redirection Test");
        return "hello";
    }
}

hello.jsp

<html>
<body>
	<h1>JavaBeat Spring MVC Examples</h1>
