import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class Login{
	
        /**转发**/
	@RequestMapping("/login.do")
	public String login(HttpServletRequest request,HttpServletResponse 

response){
		request.setAttribute("message", "hello");
		return "forward:/index.do";  //forward在跳转后可以取到message值
	}
	@RequestMapping("/index.do")
	public String index(HttpServletRequest request,HttpServletResponse 

response){
		return "welcome";
	}
	
	/**重定向**/
	@RequestMapping("/logout.do")
	public String logout(HttpServletRequest request,HttpServletResponse 

response){
		request.setAttribute("message", "hello");
		return "redirect:/register.do";  //redirect在跳转后无法取到message

值
	}
	@RequestMapping("/register.do")
	public String register(HttpServletRequest request,HttpServletResponse 

response){
		return "register";
	}
}

另外forward跳转后地址栏URL不会改变 而redirect会改变

测试URL：

http://localhost:8080/spring_forward/login.do

http://localhost:8080/spring_forward/logout.do
