1. 前言

每次启动SpringBoot，都需要java -jar xxx.jar，也没毛病，但是也麻烦，如果能有一个通用脚本启动就更好了！

#!/bin/bash
export JAVA_HOME=/usr/local/jdk8
export CLASS_PATH=.:
export PATH=$JAVA_HOME/bin:$PATH
#SpringBoot=$2
SpringBoot=

echo $1 $2

if [ "$1" = "" ];
then
    echo -e "\033[0;31m 未输入操作名 \033[0m  \033[0;34m {start|stop|restart|status} \033[0m"
    exit 1
fi

SpringBoots=`ls ./*.jar`
if [ "$SpringBoots" = "" ];
then
    echo -e "\033[0;31m 文件中没有对应的应用 \033[0m"
    exit 1
fi
for sb in $SpringBoots
do
    SpringBoot=$sb
    break
done


if [ "$SpringBoot" = "" ];
then
    echo -e "\033[0;31m 未输入应用名 \033[0m"
    exit 1
fi

function start()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        nohup java -jar $SpringBoot > /dev/null 2>&1 &
        echo "Start $SpringBoot success..."
    fi
}

function stop()
{
    echo "Stop $SpringBoot"
    boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

    if [ $count != 0 ];then
        kill $boot_id
        count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

        boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
        kill -9 $boot_id
    fi
}

function restart()
{
    stop
    sleep 2
    start
}

function status()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        echo "$SpringBoot is not running..."
    fi
}

case $1 in
    start)
    start;;
    stop)
    stop;;
    restart)
    restart;;
    status)
    status;;
    *)

    echo -e "\033[0;31m Usage: \033[0m  \033[0;34m sh  $0  {start|stop|restart|status}  {SpringBootJarName} \033[0m
\033[0;31m Example: \033[0m
      \033[0;33m sh  $0  start esmart-test.jar \033[0m"
esac

2. 使用说明

操作：sh app.sh {start|stop|restart|status} {SpringBootJarName}

当然，{SpringBootJarName}可以省略，默认找当前目录下的.jar文件启动；

需要将脚本第二行的JAVA_HOME目录改为自己的实际目录：export JAVA_HOME=/usr/local/jdk8

如果需要指定一些额外参数，可以在启动函数中修改：

更好的实践是：将该脚本保存执行文件，添加环境变量，然后在全局执行app.sh {start|stop|restart|status} {SpringBootJarName}
