WebSocket Cors and Gradle

Gradle need to use bootrepackage which would package all the dependencies, not to use Jar task which would only package your Main class Code

WebSocket use of levels of cors.

1. HTTP level:

Package Org.sang;

Import java.io.IOException;

Import Javax.servlet.Filter;
Import Javax.servlet.FilterChain;
Import Javax.servlet.FilterConfig;
Import javax.servlet.ServletException;
Import Javax.servlet.ServletRequest;
Import Javax.servlet.ServletResponse;
Import Javax.servlet.http.HttpServletRequest;
Import Javax.servlet.http.HttpServletResponse;

Import org.springframework.stereotype.Component;
Import Org.springframework.web.bind.annotation.CrossOrigin;

@CrossOrigin
@Component
public class Simplecorsfilter implements Filter {

@Override
public void DoFilter (ServletRequest req, servletresponse Res, Filterchain chain) throws IOException, Servletexception {
HttpServletResponse response = (httpservletresponse) res;
System.out.println ("Hello");
HttpServletRequest reqs = (httpservletrequest) req;
Response.setheader ("Access-control-allow-origin", Reqs.getheader ("Origin"));

System.out.println (Reqs.getheader ("Origin"));
Response.setheader ("Access-control-allow-methods", "POST, GET, PUT, OPTIONS, DELETE, PATCH");
Response.setheader ("Access-control-max-age", "3600");
Response.setheader ("Access-control-allow-headers", "Origin, X-requested-with, Content-type, Accept");
Response.setheader ("Access-control-expose-headers", "location");
Response.setheader ("Access-control-allow-credentials", "true");
Chain.dofilter (req, res);
}

@Override
public void init (Filterconfig filterconfig) {}

@Override
public void Destroy () {}

}

2 Stomplevel:

public void Registerstompendpoints (Stompendpointregistry stompendpointregistry) {
Stompendpointregistry.addendpoint ("/endpointsang"). Setallowedorigins ("*"). WITHSOCKJS ();
}
