session過時狀況下ajax請求不會觸發從新登陸的問題

• 在攔截器中添加如下邏輯

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

 

• 頁面ajax配置全局函數：

//定義ajax全局事件
$(document).ajaxError(function(jqxhr, error) {
    var sessionStatus = error.getResponseHeader("sessionStatus");
    if (sessionStatus == "timeout") {
        $.MsgBox.Alert("系統提示", "您的登陸信息已過時，請從新登陸！", function(){
            top.location.href = "${pageContext.request.contextPath}";
        })
    }
    var operationStatus = error.getResponseHeader("operationStatus");
    if (operationStatus == "refused") {
        $.MsgBox.Alert("系統提示", "您沒有權限執行該操做！", function(){
            top.location.href = contextPath;
        })
    }
});
