JSF中的会话超时 [英] session-timeout in JSF

问题描述

我使用以下代码在JSF中创建会话对象.问题是，当我尝试访问userdet对象后，它可能由于会话超时而给了我异常.无论如何，有没有增加JSF中的会话超时的方法.

I use the following codes to create a session object in JSF. The problem is that after sometime when I am trying to access userdet object it is giving me exception possibly because of session timeout. Is there anyway to increase the session timeout in JSF.

            FacesContext context = FacesContext.getCurrentInstance();
            HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
            session.setAttribute("userdet",user);

当我使用servlet时，我使用以下代码，但是它也适用于JSF吗?

When I use servlet I use the following codes but is it applicable to JSF also?

<web-app ...>
    <session-config>
        <session-timeout>20</session-timeout>
    </session-config>
</web-app>

推荐答案

是. JSF应用程序的会话超时也在web.xml中设置.

Yes. Session timeout for JSF applications is set in web.xml too.

实际上，JSF使用Java Servlet来处理http请求和响应.

In fact JSF makes use of Java Servlets to handle http requests and responses.
