public class LambdaFunctionHandler implements RequestHandler<Object, String> {

    @Override
    public String handleRequest(Object input, Context context) {
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                System.out.println("Hello");
            }
        }
    Thread thread1 = new Thread(runnable);
    thread1.start();
    Thread thread2 = new Thread(runnable);
    thread2.start();
    Thread thread3 = new Thread(runnable);
    thread3.start();
    Thread thread4 = new Thread(runnable);
    thread4.start();

    }}

我已经正常尝试过，效果很好。但在 lambda 函数上，它将无法正常工作。线程在线程完全执行之前死亡。当调用 return 语句时，它会自动停止线程。
