shiro在springMVC 如何处理登陆失败跳到登陆页面呢？

我的登陆的方法：

    @RequestMapping(value = "/dologin.req")
    public String doLogin(HttpServletRequest request, Model model) {
        String msg = "";
        String userName = request.getParameter("userName");
        String password = request.getParameter("password");
        UsernamePasswordToken token = new UsernamePasswordToken(userName, password);
        token.setRememberMe(true);
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(token);
            if (subject.isAuthenticated()) {
                return "redirect:/home.req";
            } else {

                return "login";
            }
        } catch (IncorrectCredentialsException e) {
            msg = "登录密码错误. Password for account " + token.getPrincipal() + " was incorrect.";
            model.addAttribute("message", msg);
            System.out.println(msg);
        } catch (ExcessiveAttemptsException e) {
            msg = "登录失败次数过多";
            model.addAttribute("message", msg);
            System.out.println(msg);
        } catch (LockedAccountException e) {
            msg = "帐号已被锁定. The account for username " + token.getPrincipal() + " was locked.";
            model.addAttribute("message", msg);
            System.out.println(msg);
        } catch (DisabledAccountException e) {
            msg = "帐号已被禁用. The account for username " + token.getPrincipal() + " was disabled.";
            model.addAttribute("message", msg);
            System.out.println(msg);
        } catch (ExpiredCredentialsException e) {
            msg = "帐号已过期. the account for username " + token.getPrincipal() + "  was expired.";
            model.addAttribute("message", msg);
            System.out.println(msg);
        } catch (UnknownAccountException e) {
            msg = "帐号不存在. There is no user with username of " + token.getPrincipal();
            model.addAttribute("message", msg);
            System.out.println(msg);
        } catch (UnauthorizedException e) {
            msg = "您没有得到相应的授权！" + e.getMessage();
            model.addAttribute("message", msg);
            System.out.println(msg);
        }

        return "login";
    }

登陆错误的时候：

我的springmvc下返回目录views下，的确没有login.jsp，应为login.jsp如图已经在web-app下。

那么如何设置登陆错误 跳回login.jsp下呢？

下面是我的shiro的配置文件：

<bean id = "shiroFilter" class = "org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <!-- Shiro的核心安全接口，这个属性是必须的 -->
        <property name = "securityManager" ref = "securityManager"></property>
        <!-- 要求登录时的链接(登录页面地址)，非必须的属性，默认会自动寻找Web工程根目录下的"/login.jsp"页面 -->
        <property name = "loginUrl" value = "/login.jsp" />
        <!-- 登录成功后要跳转的连接(本例中此属性用不到，因为登录成功后的处理逻辑在LoginController里硬编码) -->
         <!--<property name="successUrl" value="/home.jsp" ></property>-->
        <!-- 用户访问未对其授权的资源时，所显示的连接 -->
        <property name = "unauthorizedUrl" value = "/login.jsp"></property>
        <property name = "filterChainDefinitions">
            <value>
                /dologin.req = anon
                /**=authc
                /WEB-INF/views/=authc
            </value>
        </property>
    </bean>

web-info 目录下的文件不能直接访问,必须通过后台请求跳转

可以用SpringMVC中的action拦截器实现 具体参考：http://www.cnblogs.com/liukem...

1. 你的login.jsp是jsp文件，是需要服务器去解析再返回的，不能直接这样给jsp的路径。

2. 在WEB-INF目录下的jsp如果不是通过服务器解析直接去请求是访问不到的。

3. 根据你的问题所说你的view目录下面是没有login.jsp，这可能是你的路径错了。

4. 你的shiro配置路径中，其中loginUrl应该配置为服务器的请求路径而不是jsp文件路径。例如填/login，你的请求路径你需要写在springmvc中，例如到login这个方法时，则

return "login"
