Transportgetsstuck

在编程中，当数据被传输时出现Transport gets stuck（传输卡住）这个问题可能会出现。这种情况一般是因为程序执行过程中出现了死锁，而没有释放锁所导致的。解决该问题的方法是查找哪些代码处于死锁状态，并通过解决死锁情况来解决问题。下面是一个Java示例：

public class DeadlockExample {

    public static void main(String[] args) {
        Object resourceA = new Object();
        Object resourceB = new Object();
        Thread thread1 = new Thread(() -> {
            synchronized (resourceA) {
                System.out.println("Thread 1 acquired resource A");
                try {
                    Thread.sleep(100);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                synchronized (resourceB) {
                    System.out.println("Thread 1 acquired resource B");
                }
            }
        });

        Thread thread2 = new Thread(() -> {
            synchronized (resourceB) {
                System.out.println("Thread 2 acquired resource B");
                synchronized (resourceA) {
                    System.out.println("Thread 2 acquired resource A");
                }
            }
        });

        thread1.start();
        thread2.start();
    }

}

上述代码中存在死锁状态，即线程1持有resourceA并等待获取resourceB，线程2持有resourceB并等待获取resourceA。该代码运行时会发生Transport gets stuck问题。解决方法是通过重构代码，不让线程1和线程2同时锁住所有资源，即将其中一个线程取得资源的顺序改变，如下所示：

Thread thread1 = new Thread(() -> {
    synchronized (resourceA) {
        System.out.println("Thread 1 acquired resource A");
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        synchronized (resourceB) {
            System.out.println("Thread 1 acquired resource B");
        }
    }
});

Thread thread2 = new Thread(() -> {
