static void sleep(long milliseconds)
Thread.sleep(long)，规避 SonarQube 会扫描 Thread.sleep 代码。
Using Thread.sleep in a test is just generally a bad idea. It creates brittle tests that can fail unpredictably depending on environment ("Passes on my machine!") or load.
也可以使用 TimeUnit.sleep(long) 去替代 Thread.sleep 代码
