Spring Boot Websockets无法启动bean'subProtocolWebSocketHandler'；嵌套异常是java.lang.IllegalArgumentException：没有处理程序

Question

我的Spring Boot WebSocket应用程序抛出：

org.springframework.context.ApplicationContextException: Failed to start bean 'subProtocolWebSocketHandler'; nested exception is java.lang.IllegalArgumentException: No handlers
    at org.springframework.context.support.DefaultLifecycleProcessor.doStart(DefaultLifecycleProcessor.java:185) ~[spring-context-5.1.4.RELEASE.jar:5.1.4.RELEASE]
    at org.springframework.context.support.DefaultLifecycleProcessor.doStart(DefaultLifecycleProcessor.java:174) ~[spring-context-5.1.4.RELEASE.jar:5.1.4.RELEASE]
    at org.springframework.context.support.DefaultLifecycleProcessor.access$200(DefaultLifecycleProcessor.java:53) ~[spring-context-5.1.4.RELEASE.jar:5.1.4.RELEASE]

并且我已经隔离出问题来自我的@Postconstruct方法中的一行代码：

@Component
public class AuthenticationChannelInterceptorAdapter implements ChannelInterceptor {

  @Autowired
  private ApplicationContext applicationContext;

  @PostConstruct
  public void initialized() {
    for (String beanName : applicationContext.getBeanDefinitionNames()) {
      System.out.println(beanName);
      // The line below causes the error
      Object bean = applicationContext.getBean(beanName);
    }
  }

  @Override
  public Message<?> preSend(final Message<?> message, final MessageChannel channel) throws AuthenticationException {
    return message;
  }
}

当我注释掉Object bean = applicationContext.getBean(beanName);时，该应用程序可以正常启动，并且我的WebSocket可以正常工作。

似乎通过applicationContext.getBean(beanName)获取bean时，@PostConstruct方法执行时间更长，这导致依赖它的代码的其他部分中断。

作为参考，这是我的拦截器的注册方式：

@Configuration
@EnableWebSocketMessageBroker
public class StompWebsocketConfig implements WebSocketMessageBrokerConfigurer {

  @Autowired
  private AuthenticationChannelInterceptorAdapter authenticationChannelInterceptorAdapter;

  @Override
  public void configureMessageBroker(MessageBrokerRegistry registry) {
    registry
      .setApplicationDestinationPrefixes("/app")
      .enableSimpleBroker("/topic");
  }

  @Override
  public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/ws-endpoint").withSockJS();
  }

  @Override
  public void configureClientInboundChannel(final ChannelRegistration registration) {
    registration.setInterceptors(authenticationChannelInterceptorAdapter);
  }

}

我知道registration.setInterceptors已过时，但我没有找到任何替代方法的指南。
