并发编程系列【模拟并发请求压测】

压测代码：

@SpringBootTest
@Slf4j
public class FastBootApplicationTest {
    /**
     * 并发数量

    public static final int THREAD_NUM=14000;private static final String url="http://localhost:8084/dept/100";

    public static void main(String[] args) {
        CountDownLatch countDownLatch = new CountDownLatch(THREAD_NUM);
        for (int i = 0; i < THREAD_NUM; i++) {

            new Thread(()-> {

                    try {
                        //开始倒计数，每次减1，直到计够THREAD_NUM次
                        countDownLatch.countDown();
                        //阻塞等待
