java - Struts2 Ajax CORS -

i'm trying call struts2 action call domain. struts2 on localhost:8080 while 1 make ajax call on one, localhost:3000. i've tried put sample.json file on struts2 project folder under web folder, can ajax call on sample.json file. problem is, when i'm trying request action class, error says:

xmlhttprequest cannot load http://localhost:8080/workforce/loginaction. response preflight request doesn't pass access control check: no 'access-control-allow-origin' header present on requested resource. origin 'http://localhost:3000' therefore not allowed access. 

my problem is, can ajax call on sample json file under same project http://localhost:8080/sample.jsonbut not struts2 action class?

struts2 action:

package com.workforce.actions;  import com.opensymphony.xwork2.actionsupport; import com.opensymphony.xwork2.modeldriven; import com.workforce.models.usermodel;  public class loginaction extends actionsupport implements modeldriven<usermodel>{  /**  *   */ private static final long serialversionuid = 1l; private usermodel user = new usermodel();  @override public string execute() throws exception {     // todo auto-generated method stub      user.setemail("sampleemail");     user.setpassword("12345");      system.out.println(user.getemail());     system.out.println(user.getpassword());      return success; }  @override public usermodel getmodel() {     // todo auto-generated method stub     return user; } } 

struts2 xml

<struts> <constant name="struts.devmode" value="true" />  <package name="default" extends="struts-default, json-default">      <interceptors>         <interceptor-stack name="mystack">             <interceptor-ref name="defaultstack" />             <interceptor-ref name="json" />         </interceptor-stack>     </interceptors>      <action name="loginaction" class="com.workforce.actions.loginaction">         <interceptor-ref name="mystack" />         <result name="success" type="json"/>          <result name="input" type="json">             <param name="statuscode">500</param>             <param name="errorcode">500</param>         </result>     </action> </package> 

web.xml

ajax call

var request = {             url: "http://localhost:8080/workforce/loginaction",             method: "post",             headers:{                 "content-type": "application/json"             },               data: {                 user: self.user             }         };          $http(request).then(function(response){             console.log(response);         });

i've tried comment out struts2 config in web.xml , create sample servlet.. , works! want know how can configure corsfilter struts2 filter

after while, i've solved putting first corsfilter rather struts2 filter. works. thanks.
