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...)
