我嘗試通過apache-commons-exec捕獲python進程輸出。但它看起來不會打印輸出,只有在python過程完成後才顯示輸出。PumpStreamHandler可以實時捕獲進程輸出
這裏是我的Java代碼
CommandLine cmd = CommandLine.parse("/Users/jzhang/anaconda/bin/python");
cmd.addArgument("/Users/jzhang/a.py");
DefaultExecutor executor = new DefaultExecutor();
ExecuteWatchdog watchDog = new ExecuteWatchdog(ExecuteWatchdog.INFINITE_TIMEOUT);
executor.setWatchdog(watchDog);
executor.execute(cmd);
這是Python代碼,我想蟒蛇處理退出後執行(我只得到輸出,但我要的是獲得實時輸出)
for i in range(1,10):
print(i)
import time
time.sleep(10)
