What is the method in Java to rollback a child thread?

In Java, the usual way to rollback a child thread is to interrupt its execution using the interrupt() method. This method sends a signal to the child thread, which can catch the signal and perform the necessary rollback operations. By checking Thread.currentThread().isInterrupted() in the child thread, it can determine if an interrupt signal has been received and perform the rollback operation accordingly.

Additionally, you can use a try-catch block in a child thread to catch the InterruptedException exception and perform the necessary rollback operation when the exception is caught. For example:

public class MyThread extends Thread {
    
    @Override
    public void run() {
        try {
            // 子线程执行逻辑
            if (Thread.currentThread().isInterrupted()) {
                // 中断信号
                // 进行回滚操作
                // ...
            }
        } catch (InterruptedException e) {
            // 捕获中断异常
            // 进行回滚操作
            // ...
        }
    }
}

Rollback operations can be performed in a child thread using the above method to handle exceptional situations.
