Springboot 启动脚本

Springboot项目可以直接通过

java -jar xxx.jar

命令启动,但是开启关闭还是有个脚本会比较方便。自己写了个shell脚本，功能是查找当前目录下的jar文件，然后启动，也可以关闭，重启。经过几次修改，个人觉得比较完美了，放出源码:

#! /bin/bash
# springboot的jar放同级目录下即可，只能有一个jar文件
export PATH=$JAVA_HOME/bin:$PATH
CURRENT_PATH=$(cd "$(dirname "$0")"; pwd)
JAR=$(find $CURRENT_PATH -maxdepth 1 -name "*.jar")
PID=$(ps -ef | grep $JAR | grep -v grep | awk '{ print $2 }')

case "$1" in
    start)
        if [ ! -z "$PID" ]; then
            echo "$JAR 已经启动，进程号: $PID"
        else
            echo -n -e "启动 $JAR ... \n"
            cd $CURRENT_PATH
        nohup java -jar $JAR >/dev/null 2>&1 &
            if [ "$?"="0" ]; then
                echo "启动完成，请查看日志确保成功"
            else
                echo "启动失败"
            fi
        fi
        ;;
    stop)
        if [ -z "$PID" ]; then
            echo "$JAR 没有在运行，无需关闭"
        else
            echo "关闭 $JAR ..."
              kill -9 $PID
            if [ "$?"="0" ]; then
                echo "服务已关闭"
            else
                echo "服务关闭失败"
            fi
        fi
        ;;
    restart)
        ${0} stop
        ${0} start
        ;;
    kill)
        echo "强制关闭 $JAR"
        killall $JAR
        if [ "$?"="0" ]; then
            echo "成功"
        else
            echo "失败"
        fi
        ;;
    status)
        if [ ! -z "$PID" ]; then
            echo "$JAR 正在运行"
        else
            echo "$JAR 未在运行"
        fi
        ;;
  *)
    echo "Usage: ./springboot {start|stop|restart|status|kill}" >&2
        exit 1
esac

脚本会找到当前目录下的jar文件，所以，只能放一个jar文件。 开机启动脚本:
