无法在春季自定义登录页面上显示页面

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" />** 

应用程序没有错误，但“无法显示网页”运行显示出来。

你有什么想法吗？ 感谢

自定义登录页面WEB-INF/views/login.jsp内的login.jsp

Answer 1

1. 您的登录名 - 这是什么？ HTML？ JSP？您需要编写登录页面的URI（例如/login.html），而不仅仅是/ login。

2. 尝试把你的登录页面的子目录（如/登录），允许匿名用户看到它：

< HTTP模式=“/登录/ **”安全=”无” />

然后

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

Answer 2

你说你正在使用的弹簧，所以我会假设你使用Spring MVC的，你有没有加入

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

到您的webmvc配置。

而且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 3

你需要给匿名用户登录页面的访问。下面的代码片段添加到您的HTTP元素

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

编辑。订单很重要。它必须之前插入这一行：

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

Answer 4

这应该做我猜。

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