接到一“特殊”需求，每天自动重启Tomcat，每天....，刚热身就被干死重来，我能说什么....
Windows下创建计划任务，执行restart.bat，脚本如下：
@Echo Off
Set ServiceName=Tomcat8
net stop %ServiceName%
net start %ServiceName%
rem wait 30 seconds
ping 127.0.0.1 -n 30 > nul
rem check service state
SC queryex "%ServiceName%"|Find "STATE"|Find /v "RUNNING">Nul&&(
echo %ServiceName% not running
echo Start %ServiceName%
Net start "%ServiceName%">nul||(
Echo "%ServiceName%" wont start
exit /b 1
)
echo "%ServiceName%" started
exit /b 0
)||(
echo "%ServiceName%" working
exit /b 0
)
启动后，等待30秒，查看服务状态，如果没有运行就再启动一次。
