启动类测试

import threading
import time

from ThreadUtil import stop_thread


def test1():
    while True:
        print('test1\n')
        time.sleep(1)

def test2():
    while True:
        print('test2\n')
        time.sleep(1)


# 启动线程
mainThreadId1 = threading.Thread(target=test1)
mainThreadId2 = threading.Thread(target=test2)
mainThreadId1.start()
mainThreadId2.start()
# 五秒后
time.sleep(5)
# 停止线程
stop_thread(mainThreadId1)
# 五秒后
time.sleep(5)
# 停止线程
stop_thread(mainThreadId2)
