session过时状况下ajax请求不会触发从新登陆的问题

• 在拦截器中添加如下逻辑

String requestType = request.getHeader("X-Requested-With");
            if (!StringUtils.isEmpty(requestType) && requestType.equalsIgnoreCase("XMLHttpRequest")) {
                response.setHeader("sessionStatus", "timeout");
                response.sendError(518, "session timeout.");
            }

 

• 页面ajax配置全局函数：

//定义ajax全局事件
$(document).ajaxError(function(jqxhr, error) {
    var sessionStatus = error.getResponseHeader("sessionStatus");
    if (sessionStatus == "timeout") {
        $.MsgBox.Alert("系统提示", "您的登陆信息已过时，请从新登陆！", function(){
            top.location.href = "${pageContext.request.contextPath}";
        })
    }
    var operationStatus = error.getResponseHeader("operationStatus");
    if (operationStatus == "refused") {
        $.MsgBox.Alert("系统提示", "您没有权限执行该操做！", function(){
            top.location.href = contextPath;
        })
    }
});
