java - Spring post 重定向到 access-denied while get 工作

Question

我对有点重复的帖子表示歉意，我昨天问了一个关于这个问题的问题，但是我没有很好地陈述问题，因此反馈没有用。从那以后，我对这个问题有了更多的了解，并且可以用更清晰、简洁的方式表达出来，希望有助于解决这个问题。

每当我尝试发布到页面时， Controller 都会将 url 映射到 mvc-dispatch-servlet.xml 指定的访问拒绝处理程序。如果我尝试访问某个页面，那么它会命中正确的@requestmapping，并且一切正常。

我尝试过添加

<intercept-url pattern="/pages/ReceiveFile" access="permitAll"/>

什么也不做。

我最近刚刚将这个问题缩小到

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

这似乎阻碍了后期操作。如果我将其更改为/pages/*，那么我可以发布到/ReceiveFile 页面，因为它在 web.xml 中以这种方式映射。这完全跳过了主 Controller 。使用该设置，如果我尝试转到pages/ReceiveFile，它仍然会通过 Controller 并转到 403 页面。我不认为通过所有后期操作绕过我的 Controller 是一个好的永久解决方案。

如何允许这些后期操作进行？

谢谢!

主 Controller .java删除一些代码以减少不必要的长度

Answer 1

我不是 100% 确定，但我认为正是这行配置导致了 spring-security.xml 中的问题:

<csrf/>

如果启用CSRF在安全性中，您的帖子请求需要更新以包含一些额外的信息。它解释了为什么 GET 有效，但 POST 无效。

对于您的情况，请尝试将其删除，然后查看是否可以解决问题。
