前提：windows上安装jdk

1.启动jar脚本

@echo off
START "app" javaw -jar app-0.0.1-SNAPSHOT.jar

2.停止jar脚本(如：jar包端口9090)

@echo off
set port=9090
for /f "tokens=1-5" %%i in ('netstat -ano^|findstr ":%port%"') do (
 echo kill the process %%m who use the port 
 taskkill /pid %%m -t -f
 goto q
)
:q

3.重启jar脚本(就是上面两个合起来)

@echo off
set port=9090
for /f "tokens=1-5" %%i in ('netstat -ano^|findstr ":%port%"') do (
 echo kill the process %%m who use the port 
 taskkill /pid %%m -t -f
 goto start
)
:start
 
START "app" javaw -jar app-0.0.1-SNAPSHOT.jar
