1.  准备1个可以java -jar 方式启动的jar

常见的2种可执行jar如下

> springboot jar启动时打包出的jar  
> 此类jar 一般是内含tomcat/jetty web等容器的fat jar

> maven 打包传统java项目生成的jar  
> 如 含netty的client/server程序, swing程序，console程序,javafx程序等依靠maven配置mainClass的项目

1.  准备如下的bat脚本

@echo off
    
    rem jar平级目录
    set AppName=your_app.jar
    
    rem JVM参数
    set JVM_OPTS="-Dname=%AppName%  -Duser.timezone=Asia/Shanghai -Xms128m -Xmx128m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"
    
    
    ECHO.
    	ECHO.  [1] 启动%AppName%
    	ECHO.  [2] 关闭%AppName%
    	ECHO.  [3] 重启%AppName%
    	ECHO.  [4] 启动状态 %AppName%
    	ECHO.  [5] 退 出
    ECHO.
    
    ECHO.请输入选择项目的序号:
    set /p ID=
    	IF "%id%"=="1" GOTO start
    	IF "%id%"=="2" GOTO stop
    	IF "%id%"=="3" GOTO restart
    	IF "%id%"=="4" GOTO status
    	IF "%id%"=="5" EXIT
    PAUSE
    :start
        for /f "usebackq tokens=1-2" %%a in (`jps -l ^| findstr %AppName%`) do (
    		set pid=%%a
    		set image_name=%%b
    	)
    	if  defined pid (
    		echo %%is running
    		PAUSE
    	)
    
    start javaw %JVM_OPTS% -jar %AppName%
    
    echo  starting……
    echo  Start %AppName% success...
    goto:eof
    
    rem 函数stop通过jps命令查找pid并结束进程
    :stop
    	for /f "usebackq tokens=1-2" %%a in (`jps -l ^| findstr %AppName%`) do (
    		set pid=%%a
    		set image_name=%%b
    	)
    	if not defined pid (echo process %AppName% does not exists) else (
    		echo prepare to kill %image_name%
    		echo start kill %pid% ...
    		rem 根据进程ID，kill进程
    		taskkill /f /pid %pid%
    	)
    goto:eof
    :restart
    	call :stop
        call :start
    goto:eof
    :status
    	for /f "usebackq tokens=1-2" %%a in (`jps -l ^| findstr %AppName%`) do (
    		set pid=%%a
    		set image_name=%%b
    	)
    	if not defined pid (echo process %AppName% is dead ) else (
    		echo %image_name% is running
    	)
    goto:eof
