Spring-Sock.js-websockets:被CORS策略阻止

Question

我正在客户端应用程序上用sock.js+stomp.js实现Spring应用程序的websocket。当尝试连接时，我收到错误：

Access to XMLHttpRequest at 'http://localhost:8080/ws/tracker/info?t=...' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

在我的WebsocketConfiguration:中

@Configuration
@EnableWebSocketMessageBroker
@Order(Ordered.HIGHEST_PRECEDENCE + 99)
public class WebsocketConfiguration implements WebSocketMessageBrokerConfigurer {
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/ws")
.setAllowedOrigins("*")
.withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic/", "/queue/");
registry.setApplicationDestinationPrefixes("/app");
}
}

客户端库：

<script src="https://cdnjs.cloudflare.com/ajax/libs/sockjs-client/1.4.0/sockjs.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/stomp.js/2.3.3/stomp.js"></script>

客户端连接：

var socket = new SockJS('http://localhost:8080/websocket/tracker');

我已经在早期的一个项目中实现了websocket，所以这都是从中复制的，尽管我不记得(也找不到(如何解决这个错误。

检查是否有ClientForwardController，映射应该是这样的：

@GetMapping(value = {"/{path:[^\.]*}", "/{path:^(?!websocket).*}/**/{path:[^\.]*}"})
public String forward() {
return "forward:/";
}
