Windows server服务器上面的tomcat老是不定时挂掉, 于是利用定时操作脚本判断tomcat80端口是否在运行, 如果运行则放过, 如果down掉就启动tomcat,解决tomcat不定时挂掉导致业务数据流通丢失问题

1. @echo off<nul 3>nul
2. @echo off&title Checking For System, Do Not Switch Off, Thankyou...
3. set num=8090
4. for /f "tokens=3 delims=: " %%a in ('netstat -an') do (
5. if "%%a"=="%num%" goto en
6. )
7. if not "%%a"=="%num%" goto en1
8.  
9. :en
10. echo.Checking For local%NUM%Port is Opening...
11. pause
12. exit
13.  
14. :en1
15. echo.Checking For local%NUM%Port is Not Opening...
16. echo.Starting Tomcat Program...
17. call "%CATALINA_HOME%"\bin\startup.bat
18. echo.Starting Succes!
19. echo.OK!
20.  
21. pause
22. exit

第一段代码@echo off<nul 3>nul

::如果放在win启动计划中,如需要就开启第六行代码,

::作用是检测完马上自动关闭检测脚本待下次运行, 如果不开启就是检测完停留等待手动关闭,

::作用:窗口叠加
