Python中进程无法结束的处理办法

1.方法一 http://hi.baidu.com/javalang/item/72fabf2359a30b464799625e

也就是说当线程使用start方法运行起来后，只有当run方法运行结束，一个线程才会结束。

import threading
from threading import Thread
import time
class MyThread(Thread):
    over=False
    def __init__(self):
        Thread.__init__(self)

    def run(self):
        while not self.over:
            print "hello"
            time.sleep(2)
    def kill(self):
        self.over=True

if __name__==\'__main__\':
    t=MyThread()
    t.start()
    print \'wait 5s\'
    time.sleep(5)
    t.kill()

该方法适合run()方法中不包含死循环程序，若run()包含死循环，则此方法无法结束该线程

2.方法二

import threading
import thread
import time
import os
import urllib

def timer():
time_start = time.time()
while(1):
time_end = time.time()
if ((time_end - time_start) > 4):
return 1

def printf():
i = 0
while(1):
i = i + 1
print i
time.sleep(1)

def run():
sub_thread1 = thread.start_new_thread(printf,())
try:
if(timer()):
sub_thread1.exit()
except AttributeError:
pass
print "stop\n"
print "success\n"

if __name__==\'__main__\':
run()

开一个线程，该线程为死循环，则使用Thread类的exit方法可以退出，一般情况建议使用Thread.threading

若子线程触发了一个新的进程，则此方法无效，需使用父进程杀死该子进程

方法三：

import threading
import thread
import time
import os
import urllib

def timer():
time_start = time.time()
while(1):
time_end = time.time()
if ((time_end - time_start) > 10):
return 1

def printf():
i = 0
while(1):
i = i + 1
print i
time.sleep(1)
#if(i > 15):
# break

def run(filename):
sub_thread = thread.start_new_thread(os.system,(\'java -jar\'+\' \'+ filename,))
try:
if(timer()):
sub_thread.exit()
except AttributeError:
pass
tasks = os.popen(\'jps -m\').readlines()
#print tasks
found_task = ""
PID_end_position = 0
for task in tasks:
if filename[3:] in task:
found_task = task
PID_end_position = found_task.find(filename[3:]) - 1
break
if found_task:
PID = found_task[0 : PID_end_position]
os.system("taskkill /f /PID " + PID)
time.sleep(3)
os.system(\'del /f\'+\' \'+filename)

if __name__==\'__main__\':
run(\'D:\\ba-finance-tuangou-bp-job-1.0.1-SNAPSHOT.jar\')
