'Access-Control-Allow-Origin' header is not present on the requested resource

How to debug this problem ?

This is my java code. I give permission for all ip by setting Access-Control-Allow-Origin, but still it says no "Access-Control-Allow-Origin"

   return Response.ok().entity(jsonNodeToSend.toString()).header("Access-Control-Allow-Origin", "*").build();

This is my javascript code.

var dict = {
"clientMac" : "48:43:7c:53:53:d1",
"BSSID" : ""
};

$.ajax({
type: 'POST',
url: 'http://104.155.189.170:8080/Localization/rest/clientMacPosition/get/7',
crossDomain: true,
contentType: "application/json; charset=UTF-8",
data: dict,
dataType: 'json',
beforeSend: function(xhr) {
    xhr.setRequestHeader('MessageId', 'abc123');
},
success: function(responseData, textStatus, messageId) {
    console.log("success");
},
error: function(responseData, textStatus, errorThrown) {
    console.log(textStatus);
    console.log(responseData);
    console.log(errorThrown);
}

});

Here is my method which gets the data and respond to the request.

@Path("/get/{customerProjectId}")
@POST
@Produces({ MediaType.APPLICATION_JSON })
public Response gettingRecentPosition(LocationAPIReceiverDTO locationAPIReceiverDTO,
                                      @PathParam("customerProjectId") int customerProjectId) {

     JsonNode jsonNodeToSend = null;


    return Response.ok().entity(jsonNodeToSend.toString()).header("Access-Control-Allow-Origin", "*").build();


}

URL: http://104.155.189.170:8080/Localization/rest/clientMacPosition/get/7

jsonData : { "clientMac" : "48:43:7c:53:53:d1", "BSSID" : "33:" }

My REST call response in POST man.

Please create a filter for your application and add the following header to fix CORS issue:

public class ApplicationFilter implements Filter {

 @Override
 public void destroy() {
     // TODO Auto-generated method stub

 }

 @Override
 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
 throws IOException, ServletException {

     HttpServletRequest httpRequest = (HttpServletRequest) request;
     HttpServletResponse httpResponse = (HttpServletResponse) response;
     httpResponse.setHeader("Access-Control-Allow-Origin", httpRequest.getHeader("Origin"));
     httpResponse.setHeader("Access-Control-Allow-Credentials", "true");
     httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE,PUT");
     httpResponse.setHeader("Access-Control-Max-Age", "3600");
     httpResponse.setHeader("Access-Control-Allow-Headers", "x-requested-with,Authorization, Content-Type,*");
     if (httpRequest.getMethod().equals("OPTIONS")) {
         httpResponse.setStatus(HttpServletResponse.SC_OK);
         return;
     }
     chain.doFilter(httpRequest, httpResponse);
 }


 @Override
 public void init(FilterConfig arg0) throws ServletException {
     // TODO Auto-generated method stub

 }

}

Have you tried to put @CrossOrigin annotation on your controller method?

Here is an example of how to set up cross origin with spring: https://spring.io/guides/gs/rest-service-cors/
