用spring boot框架做的项目，将第三方包全部打在jar里面，通过shell脚本启动和停止服务，常用的shell脚本模板如下：

#!/bin/bash
JAVA_OPTIONS_INITIAL=-Xms128M
JAVA_OPTIONS_MAX=-Xmx512M
_JAR_KEYWORDS=monitor-alarm-task-1.0-SNAPSHOT.jar
APP_NAME=monitor-alarm-task
APPLICATION_FILE=/opt/scpip_monitor/application.properties
PID=$(ps aux | grep ${_JAR_KEYWORDS} | grep -v grep | awk '{print $2}' )
ALARM_CONFIG_FILE=`pwd`/alarmConfig.yaml


function check_if_process_is_running {
 if [ "$PID" = "" ]; then
 return 1
 fi
 ps -p $PID | grep "java"
 return $?
}



case "$1" in
 status)
 if check_if_process_is_running
 then
 echo -e "\033[32m $APP_NAME is running \033[0m"
 else
 echo -e "\033[32m $APP_NAME not running \033[0m"
 fi
 ;;
 stop)
 if ! check_if_process_is_running
 then
 echo -e "\033[32m $APP_NAME already stopped \033[0m"
 exit 0
 fi
 kill -9 $PID
 echo -e "\033[32m Waiting for process to stop \033[0m"
 NOT_KILLED=1
 for i in {1..20}; do
 if check_if_process_is_running
 then
 echo -ne "\033[32m . \033[0m"
 sleep 1
 else
 NOT_KILLED=0
 fi
 done
 echo
 if [ $NOT_KILLED = 1 ]
 then
 echo -e "\033[32m Cannot kill process \033[0m"
 exit 1

 exit 1

 nohup java -jar -Dalarm.config.file=$ALARM_CONFIG_FILE $JAVA_OPTIONS_INITIAL $JAVA_OPTIONS_MAX $_JAR_KEYWORDS --spring.config.location=$APPLICATION_FILE > /dev/null 2>&1 & 
 echo -ne "\033[32m Starting \033[0m"

 echo "Usage: $0 {start|stop|restart|status}"
 exit 1
esac


exit 0
