springmvc中controller之间的跳转

刚开始学习springmvc，做了一个简单的登录功能

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

之后来到后台

@Controller@RequestMapping("/user/controller")public class UserController extends BaseController  {@Autowiredprotected 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";}}}

这时候通过login()我们跳转到了Home()，这时候实现了controller之间的跳转，这样登录进入到主页的时候url就不会是.....user/controller/login而是...user/controller/home了
