WebSocket无法注入属性的问题及解决方案

private static WebSocketService webSocketService; //通过static关键字让webSocketService属于WebSocketServer类
@Autowired//注入到WebSocketServer类的webSocketService属性里
public void setKefuService(WebSocketService webSocketService){
    WebSocketServer.webSocketService= webSocketService;
}

@ServerEndpoint(value = "/chat/{username}")
@Service
public class WebSocketServer {
    @Resource // @Autowired
    private RabbitTemplate rabbitTemplate;  //null
}

@ServerEndpoint(value = "/chat/{username}")
@Service
public class WebSocketServer {
    /*
     * 提供一个spring context上下文(解决方案)
     */
    private static ApplicationContext context;
    public static void setApplicationContext(ApplicationContext applicationContext) {
        WebSocketServer.context = applicationContext;
    }
}

@SpringBootApplication
public class TalkApplication {
    public static void main(String[] args) {
        //解决springboot和websocket之间使用@autowired注入为空问题
        ConfigurableApplicationContext applicationContext =
                SpringApplication.run(TalkApplication.class, args);
        //这里将Spring Application注入到websocket类中定义的Application中。
        WebSocketServer.setApplicationContext(applicationContext);
    }
}

public void sendSimpleQueue(String message) {
    String queueName = "talk";
    // 在使用的地方通过上下文去获取服务context.getBean();
    RabbitTemplate rabbitTemplate = context.getBean(RabbitTemplate.class);
    rabbitTemplate.convertAndSend(queueName, message);
}
