Question

我在尝试为Spring Web应用程序创建自定义登录页面时遇到问题。

默认登录表单正常工作。但是当我添加

**<form-login login-page="/login"  />**

应用程序运行没有错误，但“无法显示页面”显示。

你有什么想法吗？感谢

自定义登录页面是WEB-INF / views / login.jsp

中的login.jsp

Answer 1

您需要为匿名用户授予登录页面的访问权限。将以下代码段添加到 http 元素

<intercept-url pattern="/login*" access="IS_AUTHENTICATED_ANONYMOUSLY" />

编辑。订单很重要。必须先插入这一行：

<intercept-url pattern="/*" access="ROLE_USER" />

Answer 2

您的登录信息 - 它是什么？ HTML？ JSP？您需要编写登录页面的URI（例如/login.html），而不仅仅是/ login。
尝试将您的登录页面放在子目录（例如/ login）中，以便匿名用户可以看到它：

＆LT; http pattern =“/ login / **”security =“none”/＆gt;

然后

<security:form-login 
    login-page="/login/login.jsp" 
        ...

Answer 3

你说你正在使用弹簧，所以我假设你使用的是spring-mvc，你添加了

<!-- selects a static view for rendering without the need for an explicit controller -->
<mvc:view-controller path="/login"  view-name="login"/>

到你的webmvc配置。

另外，要更改登录页面映射，您可以添加

<definition extends="default" name="/login">
    <put-attribute name="body" value="/WEB-INF/views/login.jspx"/>
</definition>

Answer 4

这应该是我猜的。

   <intercept-url pattern="/login.htm" access="permitAll()"/>
   <form-login login-page="/login.htm"                    
               authentication-failure-url = "/positionViewer/login.htm?login_error=1" />

无法在spring自定义登录页面上显示页面
