Python和Java都是常用的高并發(fā)編程語言,下面分別介紹它們實(shí)現(xiàn)高并發(fā)的方法。
//Java實(shí)現(xiàn)高并發(fā)
public static void main(String[] args) {
ExecutorService executorService = Executors.newFixedThreadPool(10);
for (int i = 0; i < 1000; i++) {
executorService.execute(new Runnable() {
@Override
public void run() {
//具體業(yè)務(wù)邏輯
}
});
}
executorService.shutdown();
}
Java通過ThreadPoolExecutor實(shí)現(xiàn)高并發(fā),可以創(chuàng)建一個(gè)固定數(shù)量的線程池,按需分配任務(wù),避免了頻繁創(chuàng)建和銷毀線程的開銷。
#Python實(shí)現(xiàn)高并發(fā)
from concurrent.futures import ThreadPoolExecutor
def task():
#具體業(yè)務(wù)邏輯
if __name__ == '__main__':
executor = ThreadPoolExecutor(max_workers=10)
for i in range(1000):
executor.submit(task)
executor.shutdown()
Python通過ThreadPoolExecutor實(shí)現(xiàn)高并發(fā),與Java相似,創(chuàng)建一個(gè)固定數(shù)量的線程池,并通過submit方法添加任務(wù)到線程池,隨后調(diào)用shutdown方法等待任務(wù)執(zhí)行完畢。
