[网络协议]WebSocket注册失败问题

@Component
@ServerEndpoint(WebsocketConstants.xxx)
public class xxx{

    private static volatile CopyOnWriteArraySet<Session> sessions = new CopyOnWriteArraySet<>();
    private Session session;

  @OnOpen
    public void onOpen(Session session){
        sessions.add(session);
        this.session = session;
    }

    @OnClose
    public void close(Session session){
        sessions.remove(session);
    }

    public synchronized void send(String text){
        if(!sessions.isEmpty()){
            sessions.forEach(session->{
                if(null != session && session.isOpen()){
                    session.getAsyncRemote().sendText(text);
                }
            });
        }
    }

    @Transactional
    @Override
    public boolean update(){
        //xxx
    }
}

报错信息:

java.lang.IllegalStateException: Failed to register @ServerEndpoint class: class com.xxx.xxx$$EnhancerBySpringCGLIB$$xxxxx
?
javax.websocket.DeploymentException: Cannot deploy POJO class [com.xxx.xxxx$$EnhancerBySpringCGLIB$$xxxxx] as it is not annotated with @ServerEndpoint

问题原因:? 代理(AOP)? ? 使用了@Transactional注解导致

使用TransactionTemplate来对事务进行回滚，问题解决

 @Override
 public boolean update(){
      return transactionTemplate.execute(status ->{
           try{
               //更新操作
               return true;
           }catch (Exception e){
               status.setRollbackOnly();
               return false;
           }
      });
 }
