Spring security+Ajax会话超时问题

Question

我用Spring MVC构建了一个应用程序，并用Spring security进行了保护，一堆控制器是JSON rest服务，它们都受到了保护。我使用LoginurlAuthenticationEntryPoint来检测AJAX请求，并在会话超时发生时发送403错误代码-所有其他请求只需重定向回登录页面。

下面是Spring Security XML片段和authenticationEntryPoint java类。

<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>

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);
        }
    }
}

确认这在Spring Boot与Spring security结合的情况下也非常有效，以编程方式设置安全性而无需任何所需的XML，例如：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .antMatchers("/admin**").hasRole("ADMIN")
            // everything else
            .anyRequest().fullyAuthenticated()
        .and()
            .exceptionHandling().authenticationEntryPoint(new AjaxAwareAuthenticationEntryPoint("/login"));
}
