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
