我正在处理一个实现Web Socket的Sping Boot 应用程序，我发现了以下问题。
首先，我有一个实现WebSocketConfigurer的WebSocketConfig类：

@Configuration
@EnableWebSocket
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketConfigurer {
//public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(new SocketTextHandler(), "/deposit-notification");
    }

}

正如您在这里看到的，我正在向相关端点注册处理程序。
然后，我使用这个SocketTextHandler类来实现TextWebSocketHandler接口，该接口实现Web套接字逻辑：

@Component
public class SocketTextHandler extends TextWebSocketHandler {

    @Override
    public void handleTextMessage(WebSocketSession session, TextMessage message)
            throws InterruptedException, IOException {

        String payload = message.getPayload();
        JSONObject jsonObject = new JSONObject(payload);
        session.sendMessage(new TextMessage("Hi " + jsonObject.get("user") + " how may we help you?"));
    }

}

我还具有此SocketSecurityConfig扩展AbstractSecurityWebSocketMessageBrokerConfigurer，以便在此端点上具有最低安全配置（仅允许来自已验证用户的连接）：

public class SocketSecurityConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {

    @Override 
    protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) { 
        messages
          .simpDestMatchers("/deposit-notification").authenticated()
          .anyMessage().authenticated(); 
    }

}

问题是，现在运行我的应用程序时，我在STS堆栈跟踪中获得了以下错误消息：

为什么？出了什么问题？我错过了什么？我如何才能尝试解决这个问题？
