JSF 视图过期异常

发布于 2024-08-19 03:57:45 字数 484 浏览 10 评论 0原文

为了在 JSF 中处理 viewExpiredException，我

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/error.html</location>
</error-page>

<session-config>
    <session-timeout>1</session-timeout>
</session-config>

在 web.xml 中进行了编码。

在 error.html 中，我已重定向到原始登录页面。但问题是，即使会话过期，会话范围的 bean 也没有被清除。有什么办法可以解决这个问题吗？

To handle viewExpiredException in JSF, I coded

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>

<session-config>
    <session-timeout>1</session-timeout>
</session-config>

in web.xml.

In error.html I have redirected to original login page. But the problem is session scoped bean were not cleared out even session expired. Is there any way to solve this?

登录页面可能是从浏览器缓存请求的。通过创建一个与 FacesServlet 绑定的 Filter 来禁用它，并且在 doFilter() 方法中基本上具有以下几行，这样您就不需要无需在您想要阻止缓存的所有页面上重复此操作。

response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
response.setHeader("Pragma", "no-cache"); // HTTP 1.0.
response.setDateHeader("Expires", 0); // Proxies.

The login page is likely been requested from the browser cache. Disable it by creating a Filter which is tied to the FacesServlet and has basically the following lines in the doFilter() method, so that you don't need to repeat it over all pages which you'd like to prevent from being cached.

response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
response.setHeader("Pragma", "no-cache"); // HTTP 1.0.
response.setDateHeader("Expires", 0); // Proxies.
