}
//修改密码
@RequestMapping(value = "/passwordRest")
public String passwordRest() throws Exception {

}
登录管理控制层：
@Controller
public class LoginController {
//登录跳转
@RequestMapping(value = "/login", method = {RequestMethod.GET})
public String loginUI() throws Exception {
return "../../login";
}
//登录表单处理
@RequestMapping(value = "/login", method = {RequestMethod.POST})
public String login(Userlogin userlogin) throws Exception {
//Shiro实现登录
UsernamePasswordToken token = new UsernamePasswordToken(userlogin.getUsername(),
userlogin.getPassword());
Subject subject = SecurityUtils.getSubject();
//如果获取不到用户名就是登录失败，但登录失败的话，会直接抛出异常
subject.login(token);
if (subject.hasRole("admin")) {
return "redirect:/admin/showStudent";
} else if (subject.hasRole("teacher")) {
return "redirect:/teacher/showCourse";
