可以項目啟動的時候?qū)⑸舷挛膫鬟f給 WebSocketServer，通過上下文獲取Bean來解決

public static void main(String[] args) {
   ConfigurableApplicationContext run = SpringApplication.run(HospitalApplication.class, args);
   //解決WebSocket不能注入的問題
   WebSocketServer.setApplicationContext(run);
}

WebSocketServer.class 中: 
private static ApplicationContext applicationContext;
public static void setApplicationContext(ApplicationContext applicationContext) {
    WebSocketServer.applicationContext = applicationContext;
}

同時@Value 獲取不到，可以注入到Bean中解決
比如獲取端口號

@Component
@Data
public class ConfigValue {

    @Value("${server.port}")
    private Integer port;
}
