Windows system timer restarts custom EXE program

Source: Internet
Author: User

The Windows system periodically restarts the custom EXE program as required by the job. Write the following procedure to modify four parameters in a batch file according to the instructions (Readme.txt):

1.readme.txt

First parameter: Process name (without EXE) second parameter: Large-screen exe path third parameter: Timed task cycle time (seconds) fourth parameter: Interval between end and restart (MS)

2. batch file Dp.bat (Note: The third parameter unit is S, and the fourth parameter is MS)

Java-jar Dp.jar  Foxmail d:\\tools\\foxmail\\foxmail.exe

3.task.java (Export the project as an executable jar package Dp.jar, my operating environment is jdk1.7, but the JDK relationship should be small, not tested ...)
