使用@ServerEndpoint修饰但不用@Component时，其它Bean注入该Bean时会报 bean could not be found 异常 about netty-websocket-spring-boot-starter

我尝试的改了一下这个问题，ServerEndpointExporter 再实现一个后置处理器接口 BeanDefinitionRegistryPostProcessor,registerEndpoints中的scanPackage方法放到postProcessBeanFactory方法中执行，让扫描提前执行，就不会再报异常
`public class ServerEndpointExporter extends ApplicationObjectSupport implements SmartInitializingSingleton, BeanFactoryAware, ResourceLoaderAware,BeanDefinitionRegistryPostProcessor {

@Override
public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry beanDefinitionRegistry) throws BeansException {

}

@Override
public void postProcessBeanFactory(ConfigurableListableBeanFactory configurableListableBeanFactory) throws BeansException {
    ApplicationContext context = getApplicationContext();
    scanPackage(context);
}

protected void registerEndpoints() {
    ApplicationContext context = getApplicationContext();
    // scanPackage(context);

    String[] endpointBeanNames = context.getBeanNamesForAnnotation(ServerEndpoint.class);
    Set<Class<?>> endpointClasses = new LinkedHashSet<>();
    for (String beanName : endpointBeanNames) {
        endpointClasses.add(context.getType(beanName));
    }

    for (Class<?> endpointClass : endpointClasses) {
        if (ClassUtils.isCglibProxyClass(endpointClass)) {
            registerEndpoint(endpointClass.getSuperclass());
        } else {
            registerEndpoint(endpointClass);
        }
    }

    init();
}

}`

我怎么感觉你的用法跟我的相反了，不是应该是MyWebSocket注入其他bean吗
