Spring Security + Ajax会话超时问题 [英] Spring security + Ajax session timeout issue

问题描述

我有一个使用Spring MVC构建的应用程序，并通过Spring安全性进行了安全保护，其中许多控制器都是受JSON保护的服务.我正在使用LoginUrlAuthenticationEntryPoint来检测AJAX请求，如果发生会话超时，则发送403 错误代码-所有其他请求都被重定向回登录页面.

I have an app build with Spring MVC and secured with Spring security, a bunch of the controllers are JSON rest services that are all protected. I'm using LoginUrlAuthenticationEntryPoint to detect AJAX requests and send 403 ERROR CODE if session timeout occurs - all other requests just get redirected back to login page.

下面是Spring Security XML代码段和authenticationEntryPoint Java类.

Below is the Spring Security XML snippet and the authenticationEntryPoint java class.

问题是会话超时后的第一个AJAX请求，Spring重定向到登录页面并返回登录页面HTML，如果我尝试再次执行AJAX请求(重定向发生后)，则执行authenticationEntryPoint并返回HTTP错误代码403 .我已经尝试过使用这种机制进行相同的操作 http://distigme.wordpress.com/2012/11/01/ajax-and-spring-security-form-b​​ased-login/，并且发生了完全相同的事情(在第一个AJAX请求中，发生了重定向，所有后续的AJAX请求均返回HTTP 403).我不希望会话超时的AJAX请求重定向到登录页面.

The issue is that the first AJAX Request after session timeout, Spring redirects to login page and the returns login page HTML, if I attempt to do AJAX request again (after redirect happens) the authenticationEntryPoint executes and HTTP Error Code 403 is returned. I have attempted the same thing using this mechanism http://distigme.wordpress.com/2012/11/01/ajax-and-spring-security-form-based-login/ and the same exact thing happens (on first AJAX request a redirect occurs, all subsequent AJAX requests HTTP 403 is returned). I do not want to get Redirect to login page for AJAX requests where session is timed out.

有什么想法吗?

<beans:bean id="authenticationEntryPoint"  class="mojo.ocs.web.AjaxAwareAuthenticationEntryPoint">
    <beans:constructor-arg name="loginUrl" value="/login"/>
</beans:bean>
<!-- ENTRY POINT REF IMPLEMENTATION -->
<http auto-config="true" use-expressions="true" access-denied-page="/accessdenied" entry-point-ref="authenticationEntryPoint">
    <intercept-url pattern="/login" access="isAnonymous()"/>
    <intercept-url pattern="/loginfailed" access="isAnonymous()"/>
    <intercept-url pattern="/welcome" access="isAuthenticated()" />
    <intercept-url pattern="/" access="isAuthenticated()" />
    <intercept-url pattern="/private_res/**" access="isAuthenticated()" />
    <intercept-url pattern="/tne/**" access="isAuthenticated()" />
    <intercept-url pattern="/team_reports/**" access="isAuthenticated()" />
    <form-login login-page="/login" default-target-url="/welcome" always-use-default-target="true" authentication-failure-url="/loginfailed" />
    <logout delete-cookies="JSESSIONID"  logout-success-url="/logout" invalidate-session="true"/>
    <session-management invalid-session-url="/login" />
</http>

这是LoginAuthenticationEntryPoint:

Here is the LoginAuthenticationEntryPoint:

public class AjaxAwareAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint     
{
    public AjaxAwareAuthenticationEntryPoint(String loginUrl) {
        super(loginUrl);
    }

    @Override
    public void commence(
        HttpServletRequest request,
        HttpServletResponse response,
        AuthenticationException authException)
        throws IOException, ServletException {
        String ajaxHeader = ((HttpServletRequest) request).getHeader("X-Requested-With");
        boolean isAjax = "XMLHttpRequest".equals(ajaxHeader);
        if (isAjax) {
            response.sendError(HttpServletResponse.SC_FORBIDDEN, "Ajax REquest Denied (Session Expired)");
        } else {
            super.commence(request, response, authException);
        }
    }
}

推荐答案

我通过自己的自定义过滤器实现了此问题的解决，将其放在ANONYMOUS_FILTER之前，如果Spring主体不存在，则返回403.

I fixed this issue by implementing by own custom filter, placing it before ANONYMOUS_FILTER and return 403 if the Spring principal doesn't exist.
