python sqlite3 多线程_使用sqlite操作的Python多线程处理

我使用sqlite数据库来存储数据。我的python程序有一个包含5个线程的线程池。我创建了一个数据库连接，并与所有5个线程共享，但有时它会抛出异常，而这个异常不是由任何sqlite异常或泛型异常捕获的，我的python脚本会自动终止。在寻找解决办法之后，我遇到了

How to share single SQLite connection in multi-threaded Python application

我创建了一个单独的连接，如下所示class ProcessJob(object):

....

def process_job(self):

job = queue.get()

if job = 'xyz':

with sqlite3.connect(database_path, check_same_thread=False, timeout = 10) as db_conn:

db_conn.execute("insert query on table ABC")

db_conn.commit()

elif job = 'pqr':

with sqlite3.connect(database_path, check_same_thread=False, timeout = 10) as db_conn:

db_conn.execute("update query on table ABC")

db_conn.commit()

elif job = 'mno':

with sqlite3.connect(database_path, check_same_thread=False, timeout = 10) as db_conn:

db_conn.execute("insert query on table FOO")

db_conn.commit()

class MyThread(therading.Thread):

....

process_job_obj = ProcessJob()

def run(self):

while True:

try:

process_job_obj.process_job()

except Exception as e:

logger.exception('Exception : %s'%e)

def main():

for i in range(5):

trd = MyThread()

trd.start()

if __name__ == "__main__":

main()

那么，这是一个正确的方法，还是有任何缺陷或机会停止/终止python脚本？在
