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...)
