@Controller
public class MyController {

    @RequestMapping({"/","/index"})
    public String toIndex(Model model){
        model.addAttribute("msg","hello,shiro");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){

    }

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        //获取当前用户
        Subject subject = SecurityUtils.getSubject();
        //封装用户登录数据
        UsernamePasswordToken token = new UsernamePasswordToken(username,password);
        try {
            subject.login(token);   //执行登录方法，如果没有异常就ok了
            return "index";
