带有 404 错误的 Spring 安全问题？

Question

大家好，我使用的是 spring security 3.0.2，urlRewrite 3.1.0，我有一个spring security的问题，我有一个规则，应用程序中的所有页面都需要身份验证，除了某些页面，所以我的security.xml是:

<http use-expressions="true" > 
<intercept-url pattern="/" access="permitAll" />
<intercept-url pattern="/error"  filter="none" />  
<intercept-url pattern="/**" access="isAuthenticated()" />
.
.
.</http>

在 web.xml 中我定义了错误页面

<error-page>
   <error-code>404</error-code>
   <location>/p/error</location>
</error-page>

问题是，如果我不是登录用户，并且输入了一些应用程序中不存在的 URL，例如 app/notFoundUrl，spring security 会将此页面与需要身份验证的模式/** 匹配，所以用户没有按预期重定向到错误页面，而是重定向到登录页面，然后重定向到错误页面

我希望如果用户在登录与否时输入了错误的 url，他会直接重定向到错误页面。

我认为问题与web.xml有关，这里是:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

任何想法如何解决这个问题？

你说过:

i want that if the user typed a bad url if he's logged in or not, he's redirected to the error page directly

Spring security 会在它知道其 url 是否有效之前拦截每个请求，因此获取它的一种方法是拦截具有某些模式的所有有效 url，并在最后添加一个任何人都可以访问的通用模式.

<intercept-url pattern="/" access="permitAll" />
<intercept-url pattern="/validUrl1Pattern"  access="permitAll" />  
<intercept-url pattern="/validUrl2Pattern"  access="permitAll" />  
<intercept-url pattern="/validUrl2Pattern"  access="permitAll" />  
...
<intercept-url pattern="/**" access="ROLE_ANONYMOUS" />

这种配置的问题是，如果您的应用程序很复杂，可能很难找到所有有效 url 的模式。
