java - 无法在 spring mvc 中显示带有错误消息的同一页面

Question

这个想法很简单，如果我的登录失败，用户将被重定向到 /loginerror 但无法正常工作

登录 Controller

 @RequestMapping(value = "/login", method = RequestMethod.GET)
        public String login(Model model) {
            return "login";
        }

        @RequestMapping(value = "/loginerror", method = RequestMethod.GET)
        public String loginFailed(Model model) {
            model.addAttribute("error", "true");
            return "login";
        }

        @RequestMapping(value = "/logout", method = RequestMethod.GET)
        public String logout(Model model) {
            return "login";
        }

登录.jsp

<c:if test="${not empty error}">
                            <div class="alert alert-danger">
                                <spring:message
                                    code="AbstractUserDetailsAuthenticationProvider.badCredentials" />
                                <br />
                            </div>
                        </c:if>
                        <form action="<c:url value= "/j_spring_security_check"></c:url>"
                            method="post">
                            <fieldset>
                                <div class="form-group">
                                    <input class="form-control" placeholder="User Name"
                                        name='j_username' type="text">
                                </div>
                                <div class="form-group">
                                    <input class="form-control" placeholder="Password"
                                        name='j_password' type="password" value="">
                                </div>
                                <input class="btn btn-lg btn-success btn-block" type="submit"
                                    value="Login">
                            </fieldset>
                        </form>
                    </div>

安全上下文.xml

<security:http auto-config="true">
    <security:intercept-url pattern="/all/add"
        access="hasRole('ROLE_ADMIN')" />
    <security:form-login login-page="/login"
        default-target-url="/all/add" authentication-failure-url="/loginerror" />
    <security:logout logout-success-url="/logout" />
    <security:csrf disabled="true" />
</security:http>

<security:authentication-manager>
    <security:authentication-provider>
        <security:user-service>
            <security:user name="admin" authorities="ROLE_ADMIN"
                password="admin" />
        </security:user-service>
    </security:authentication-provider>

</security:authentication-manager>

我想做的是在登录失败时将用户重定向到登录页面，但每次我都会收到错误404页面在url localhost......../j_spring_security_check

上找不到

编辑

spring 错误消息为 AbstractUserDetailsAuthenticationProvider.badCredentials=您输入的用户名或密码不正确。

将调试语句放入 /loginerror 方法中后，我发现该方法甚至没有被调用

如果url错误如何拦截？

web.xml

<servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

您使用的spring版本不支持 <form action="<c:url value= "/j_spring_security_check"></c:url>" method="post">使用/login 作为 url 代替 <form action="<c:url value= "/login"></c:url>" method="post">既然你问这个链接清楚地解释了差异Why doesn't my custom login page show with Spring Security 4?
