I struggle with connecting my client (or through Postman) to websocket server: if got 404 response when I try to connect and following prompts in console:
Access to XMLHttpRequest at 'http://localhost:8080/ws-endpoint/info?t=1670410538045' from origin 'http://localhost:5050' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
GET http://localhost:8080/ws-endpoint/info?t=1670410538045 net::ERR_FAILED 404
On the server side, while connecting if got:
2022-12-07T11:53:13.928+01:00 INFO 16292 --- [nio-8080-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring DispatcherServlet 'dispatcherServlet'

My connection code in the client (run on the port 5050):
var socket = new SockJS('http://localhost:8080/ws-endpoint');
stompClient = Stomp.over(socket);
stompClient.connect({}, function (frame) {
console.log('Connected: ' + frame);
updateNotificationDisplay();
stompClient.subscribe('/topic/messages', function (message) {
showMessage(JSON.parse(message.body).content);
});
...
My config code on the server (port 8080):
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer{
@Override
public void registerStompEndpoints(final StompEndpointRegistry registry) {
registry.addEndpoint("/ws-endpoint").setAllowedOrigins("*").withSockJS();
}
@Override
public void configureMessageBroker(final MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
registry.setApplicationDestinationPrefixes("/websocket");
}
}
In setAllowedOrigins I tried with: *, http://localhost:5050, http://localhost:5050/**, https://localhost:5050 but still error remains.
