多线程中applicationContext.getBean方法未返回也未报错

 public class TcpServer implements ApplicationContextAware{
    private OpenbankExecutor executor;
    private int port;
    private PacketHandler packetHandler;
    private ServerSocket serverSocket;
    private Socket socket;
    private ApplicationContext applicationContext;
    private final Logger log = LoggerFactory.getLogger(getClass());
    public void init() throws IOException {
        serverSocket = new ServerSocket(port);
        log.debug("TcpServer 成功启动");
        while(true) {
            socket = serverSocket.accept();
            System.out.println("收到socket请求");
            executor.execute(new Runnable() {

                @Override
                public void run() {
                    try {
                        Map context = packetHandler.handle(socket.getInputStream());
                        String tranCode = (String) context.get("tranCode");
                        Assert.hasText(tranCode);
                        Transaction transaction = (Transaction) applicationContext.getBean(tranCode);
                        Template template = (Template) applicationContext.getBean(transaction.getTemplate());
                        log.debug("transaction: "+transaction.getId());
                        log.debug("transaction: "+template.getId());
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
        }
    }

走到Transaction transaction = (Transaction) applicationContext.getBean(tranCode);就没有往下走了，没有报错。非多线程方式下这个方法是没有问题的，比如我将这一段放到executor.execute(new Runnable() {之前就没有问题，求解
