Spring Security在显示自定义页面时出错

我正在使用Spring Security Integration，我的内置安全页面的应用程序工作正常。但对于自定义登录页面的给错误Spring Security在显示自定义页面时出错

The localhost page isn’t working

这里是我的参考

弹簧security.xml文件中的代码

<http use-expressions="true"> 
     > 

     <intercept-url pattern="/**" access="isAuthenticated()"/> <!-- this means all URL in this app will be checked if user is authenticated --> 

      <form-login 
      login-page="/login" 
      default-target-url="/" 
      authentication-failure-url="/login?error" 
      username-parameter="username" 
      password-parameter="password" /> 


     <logout logout-url="/logout" logout-success-url="/"/> <!-- the logout url we will use in JSP --> 
    </http>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> 
<html> 
<head> 
<title>Custom Login Page</title> 
</head> 
<body onload='document.loginForm.j_username.focus();'> 
<h3>Custom Login Page</h3> 

<% 

String errorString = (String)request.getAttribute("error"); 
if(errorString != null && errorString.trim().equals("true")){ 
out.println("Incorrect login name or password. Please retry using correct login name and password."); 
} 
%> 

<form name='loginForm' action="<c:url value='j_spring_security_check' />" 
method='POST'> 

<table> 
<tr> 
<td>User:</td> 
<td><input type='text' name='j_username' value=''> 
</td> 
</tr> 
<tr> 
<td>Password:</td> 
<td><input type='password' name='j_password' /> 
</td> 
</tr> 
<tr> 
<td><input name="submit" type="submit" 
value="submit" /> 
</td> 
<td><input name="reset" type="reset" /> 
</td> 
</tr> 
</table> 

</form> 
</body> 
</html>

在控制器中：

@RequestMapping(value = "/login", method = RequestMethod.GET) 
    public ModelAndView login(ModelMap mode, 
      @RequestParam(value = "error", required = false) String error, 
      @RequestParam(value = "logout", required = false) String logout) { 
     System.out.println("\n\t -------------"); 
     ModelAndView model = new ModelAndView("login"); 

     if (error != null) { 
      model.addObject("error", "Invalid username and password!"); 
     } 

     if (logout != null) { 
      model.addObject("msg", "You've been logged out successfully."); 
     } 
     return model; 

    }

当我使用的建筑形式pulgin运行项目，该网址是

http://localhost:8080/SpringMvcSecurity/spring_security_login

和登录，如果我手动打网址

http://localhost:8080/SpringMvcSecurity/login

后，它让我看到登录页面但我不这样做，如果这个页面显示这个时间，那么为什么它不显示在自定义配置。请帮忙。

感谢shazin 有4个变化

需要RequestMapping网址更改URL名称为前：customlogin

同名需要弹簧security.xml文件

添加替换line in spring-security.xml

替换用户名密码属性名称，这些出现在jsp页面的方式。

<intercept-url pattern="/customlogin" access="permitAll" />

请说明你有问题。它会返回404吗？或例外？ – shazin

shazin其显示既不例外，也不显示404消息说，localhost重定向你太多次了。就是这样。感谢您的回复 – Kamini

请不要在您的问题中发布解决方案。写一个新的答案并接受它。 – dit

shazin its shows neither exception nor 404 its displays message saying, localhost redirected you too many times..that's it. thanks for your reply

那是因为你有你的@RequestMapping价值的.jsp为login名。更改至少一个如下所示。

@RequestMapping(value = "/customlogin", method = RequestMethod.GET) 
    public ModelAndView login(ModelMap mode, 
      @RequestParam(value = "error", required = false) String error, 
      @RequestParam(value = "logout", required = false) String logout) { 
     System.out.println("\n\t -------------"); 
     ModelAndView model = new ModelAndView("login"); 

     if (error != null) { 
      model.addObject("error", "Invalid username and password!"); 
     } 

     if (logout != null) { 
      model.addObject("msg", "You've been logged out successfully."); 
     } 
     return model; 

    }

而且在配置

<http pattern="/customlogin*" security="none"/> 
<http use-expressions="true"> 
     > 
     <intercept-url pattern="/**" access="isAuthenticated()"/> <!-- this means all URL in this app will be checked if user is authenticated --> 

      <form-login 
      login-page="/customlogin" 
      default-target-url="/" 
      authentication-failure-url="/customlogin?error" 
      username-parameter="j_username" 
      password-parameter="j_password" /> 


     <logout logout-url="/logout" logout-success-url="/"/> <!-- the logout url we will use in JSP --> 
    </http>

好的，谢谢我会检查并更新你。 – Kamini

它显示相同的错误。 :( – Kamini

Shazin在添加下面的行后开始工作请编辑您的答案并添加此行并更改security.xml中的j_username和j_password – Kamini
