如何使用Spring安全性获取会话超时消息

Question

我想在会话到期时获得会话超时消息.Below是我的spring-security.xml

<http auto-config="true" use-expressions="true">
    <logout logout-success-url="/" invalidate-session="true" logout-url="/LogOut"/>
    <form-login login-page="/Login" username-parameter="Name" password-parameter="Pwd"/>
    <session-management invalid-session-url="/?timeout=true">
        <concurrency-control max-sessions="1" expired-url="/Timeout?timeout=true" />
    </session-management>
</http>

根据我的知识,当会话到期时使用上面的代码它应该重定向到/?timeout=true OR /Timeout?timeout=true.在退出时它应该去/.但在我注销的情况下,它也会重定向到invalid-session-url所以我总是在正常注销和会话超时时都超时.

请帮我区分一下.

UPDATE

/logout 请求包含

session = request.getSession();
session.invalidate();
session = null;

Answer 1

我建议您使用以下方法注销：

HttpSession session= request.getSession(false);
    SecurityContextHolder.clearContext();
        if(session != null) {
            session.invalidate();
        }
        for(Cookie cookie : request.getCookies()) {
            cookie.setMaxAge(0);
        }

我解决了!通过编写过滤器来取决于Spring-security.

如果有人感兴趣,可以使用以下代码: -

import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.text.MessageFormat;

import javax.servlet.FilterChain;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;
import org.springframework.web.filter.OncePerRequestFilter;

public class FilterToGetTimeOut extends OncePerRequestFilter {

    @Override
    public void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws IOException {
        try {
            if(request.getRequestURI().equals("/") || request.getRequestURI().equals("/Login/")){
                if(request.getSession().getAttribute("login") != null && (Boolean)request.getSession().getAttribute("login") == true){
                    response.sendRedirect(URL);     //After login page
                }
            } else if(request.getSession().getAttribute("login") == null && !request.getRequestURI().equals("/LogOut")){
                response.sendRedirect(request.getContextPath()+"/?timeout=true");   //If timeout is true send session timeout error message to JSP
            }
            filterChain.doFilter(request, response);
        } catch (Exception e) {
            //Log Exception

        }
    }
}

添加此过滤器web.xml.

    <filter>
        <filter-name>FilterToGetTimeOut </filter-name> 
        <filter-class>package.FilterToGetTimeOut </filter-class> 
    </filter>
    <filter-mapping> 
        <filter-name>FilterToGetTimeOut</filter-name> 
        <url-pattern>/*</url-pattern> 
    </filter-mapping> 

所以现在会话也无效,我也可以处理会话超时.
