导读：我正在使用 Spring MVC / Security 3.X.问题是,每当会话超时时,我在登录页面上获得403,其中Spring框架正在抛出“InvalidCsrfTokenException”： threw exception [org.springframework.security.web.csrf.InvalidCsrfTokenException: Invalid CSRF Token '7b

我正在使用 Spring MVC / Security 3.X.问题是,每当会话超时时,我在登录页面上获得403,其中Spring框架正在抛出“InvalidCsrfTokenException”：

threw exception [org.springframework.security.web.csrf.InvalidCsrfTokenException: Invalid CSRF Token '7b4aefe9-6685-4c70-adf1-0d633680523a' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.] with root cause

正如在Spring文档中提到的那样,CSRF timeout是一个应该处理的问题.处理此场景的一种方法是使用自定义AccessDeniedHandler拦截CSRF异常.就像是：

static class CustomAccessDeniedHandler extends AccessDeniedHandlerImpl{

    @Override
    public void handle(HttpServletRequest request,HttpServletResponse response,AccessDeniedException accessDeniedException)
            throws IOException,ServletException {
        if (accessDeniedException instanceof MissingCsrfTokenException
                || accessDeniedException instanceof InvalidCsrfTokenException) {

            //What goes in here???

        }

        super.handle(request,response,accessDeniedException);

    }
}

问题：无需刷新页面(这是糟糕的用户体验)或无休止的会话,处理这种情况的最佳方法是什么？感谢您的帮助.

解决方法

当会话在登录页面超时时,我发现处理无效CSRF令牌的最简单方法是以下之一：

>再次将请求重定向到登录页面vi CustomAccessDeniedHandler：

static class CustomAccessDeniedHandler extends AccessDeniedHandlerImpl{




    @Override
    public void handle(HttpServletRequest request,AccessDeniedException accessDeniedException)
    throws IOException,ServletException {
if (accessDeniedException instanceof MissingCsrfTokenException
        || accessDeniedException instanceof InvalidCsrfTokenException) {

    if(request.getRequestURI().contains("login")){
        response.sendRedirect(request.getContextPath()+"/login");                                        
    }
}

super.handle(request,accessDeniedException);



 }
}

>添加刷新标题为Neil McGuigan建议：

< meta http-equiv =“refresh”content =“${pageContext.session.maxInactiveInterval}”>

>此外,您必须为新的CustomAccessDeniedHandler创建一个bean并注册它.以下示例显示了Java配置.

在任何配置类中：

@Bean
public AccessDeniedHandler accessDeniedHandler() {
    return new CustomAccessDeniedHandler();
}

在您的安全配置中,修改configure方法,如下所示：

@Override
protected void configure(final HttpSecurity http) throws Exception {
    http
      // ...
      .and()
      .exceptionHandling().accessDeniedHandler(accessDeniedHandler());
}

另见here.

一个更优化的解决方案将是Spring安全性在其框架中处理这种情况.
