我看不到有关如何在会话超时时从ajax请求发回一些数据的好示例/答案。它发回登录页面HTML，我想发送json或我可以拦截的状态代码。

Answer 1

执行此操作的最简单方法是对AJAX请求的URL使用过滤器。

在下面的示例中，我只是发送HTTP 500响应代码，其响应正文指示会话超时，但您可以轻松地将响应代码和正文设置为更适合您的情况。

package com.myapp.security.authentication;

import org.springframework.web.filter.GenericFilterBean;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class ExpiredSessionFilter extends GenericFilterBean {

    static final String FILTER_APPLIED = "__spring_security_expired_session_filter_applied";

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;

        if (request.getAttribute(FILTER_APPLIED) != null) {
            chain.doFilter(request, response);
            return;
        }

        request.setAttribute(FILTER_APPLIED, Boolean.TRUE);
        if (request.getRequestedSessionId() != null && !request.isRequestedSessionIdValid()) {               
            response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, "SESSION_TIMED_OUT");
            return;
        }

        chain.doFilter(request, response);
    }
}

我认为这是一种非常简单的方法。这是我在这个网站上观察到的一系列方法。我写了一篇关于它的博客文章： http://yoyar.com/blog/2012/06/dealing-with-the-spring-security-ajax-session-timeout-problem/

基本思想是使用如上所述的api url前缀（即/ api / secured）以及身份验证入口点。这很简单，也很有效。

这是验证入口点：

package com.yoyar.yaya.config;

import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint;

import javax.servlet.ServletException;
import javax.servlet.http.*;
import java.io.IOException;

public class AjaxAwareAuthenticationEntryPoint 
             extends LoginUrlAuthenticationEntryPoint {

    public AjaxAwareAuthenticationEntryPoint(String loginUrl) {
        super(loginUrl);
    }

    @Override
    public void commence(
        HttpServletRequest request, 
        HttpServletResponse response, 
        AuthenticationException authException) 
            throws IOException, ServletException {

        boolean isAjax 
            = request.getRequestURI().startsWith("/api/secured");

        if (isAjax) {
            response.sendError(403, "Forbidden");
        } else {
            super.commence(request, response, authException);
        }
    }
}

这是你的春天语境中的内容xml：

<bean id="authenticationEntryPoint"
  class="com.yoyar.yaya.config.AjaxAwareAuthenticationEntryPoint">
    <constructor-arg name="loginUrl" value="/login"/>
</bean>

<security:http auto-config="true"
  use-expressions="true"
  entry-point-ref="authenticationEntryPoint">
    <security:intercept-url pattern="/api/secured/**" access="hasRole('ROLE_USER')"/>
    <security:intercept-url pattern="/login" access="permitAll"/>
    <security:intercept-url pattern="/logout" access="permitAll"/>
    <security:intercept-url pattern="/denied" access="hasRole('ROLE_USER')"/>
    <security:intercept-url pattern="/" access="permitAll"/>
    <security:form-login login-page="/login"
                         authentication-failure-url="/loginfailed"
                         default-target-url="/login/success"/>
    <security:access-denied-handler error-page="/denied"/>
    <security:logout invalidate-session="true"
                     logout-success-url="/logout/success"
                     logout-url="/logout"/>
</security:http>

我在后端使用@Matt的相同解决方案。如果您在前端使用angularJs，请在角度$ http中添加以下拦截器，让浏览器实际重定向到登录页面。

var HttpInterceptorModule = angular.module('httpInterceptor', [])
.config(function ($httpProvider) {
  $httpProvider.interceptors.push('myInterceptor');
  $httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest'; 
})
 .factory('myInterceptor', function ($q) {
return {
    'responseError': function(rejection) {
      // do something on error
        if(rejection.status == 403 || rejection.status == 401) window.location = "login";   
        return $q.reject(rejection);
    }
  };

}）;

请注意，只有在版本1.1.1之后使用AngularJs时才需要下面的行（angularJS从该版本开始删除标题“X-Requested-With”）

$httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest';

看到所有目前的答案现在都已有几年了，我将分享我目前在Spring Boot REST应用程序中工作的解决方案：

[0C40:03A0][2015-12-10T01:39:02]e000: Error 0x80190197: Failed to download http://go.microsoft.com/fwlink/?LinkId=615437&clcid=0x409; will try 2 more times.

[0C40:03A0][2015-12-10T01:39:02]e000: Error 0x80190197: Failed to download http://go.microsoft.com/fwlink/?LinkId=615437&clcid=0x409; will try 1 more times.

[0C40:03A0][2015-12-10T01:39:02]e000: Error 0x8007013d: Failed to format error message.

[0C40:03A0][2015-12-10T01:39:02]i000: Process exit code: 0x80190197 (-2145844841)

这里的基本前提是我覆盖了身份验证入口点，默认情况下是向我不存在的登录页面发出重定向。它现在通过发送401来响应.Spring还隐式创建了它返回的标准错误响应JSON对象。
