httpsession跨域请求不能保存的问题

前端设置

$.ajaxSetup( {    xhrFields: {        withCredentials: true    }} );

修改跨域请求携带cookie

后端修改

String origin = request.getHeader("Origin");if(origin != null){   response.setHeader("Access-Control-Allow-Origin", origin);}else{   response.setHeader("Access-Control-Allow-Origin", "*");}response.setHeader("Access-Control-Allow-Credentials","true");

修改后端请求允许跨域携带cookie
