• windows系统定时重启自定义exe程序


    工作需要, Windows系统定时重启自定义exe程序. 写了如下程序, 按照说明(readme.txt)修改批处理文件中的四个参数即可:

    1.readme.txt

    第一个参数:进程名(不用带exe) 
    第二个参数:大屏exe路径
    第三个参数:定时任务循环时间(秒)
    第四个参数:结束与重启的间隔时间(毫秒)

    2.批处理文件dp.bat(注意:第三个参数单位是s,第四个参数单位是ms)

    java -jar dp.jar  Foxmail D:\Tools\Foxmail\Foxmail.exe 10 5000
    pause

    3.task.java(将工程导出为可执行jar包dp.jar, 我的运行环境为jdk1.7,不过和jdk关系应该不大,没测试...)

    package com.kd;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
