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  {

@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";
}
}

}

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
