springmvc中controller之間的跳轉

剛開始學習springmvc，做了一個簡單的登錄功能

<form action="user/controller/login" method="post">

之後來到後臺

@Controller
@RequestMapping("/user/controller")
public class UserController extends BaseController  {
	
	@Autowired
	protected UserService userService;
	
	@RequestMapping("/home")
	public String Home() {
		return "user/mainPage";
	}
	
	@RequestMapping(value="/login")
	public String login(HttpServletRequest request, HttpServletResponse response) throws IOException {
		System.out.println("im in login class!!!");
		String username = request.getParameter("username");
		String password = request.getParameter("password");
		User user = userService.findByUserName(username);
		if(password.equals(user.getPassword())) {
			request.getSession().setAttribute("user", user);
			request.setAttribute("info", "login successfully");
			return "redirect:/user/controller/home";
		}
		else {
			request.setAttribute("info", "password error!");
			return "../../login";
		}
	}

}

這時候通過login()我們跳轉到了Home()，這時候實現了controller之間的跳轉，這樣登錄進入到主頁的時候url就不會是.....user/controller/login而是...user/controller/home了
