Java Shell springboot通用Shell启动脚本方式

作者：MrBlueSky

这篇文章主要介绍了Java Shell springboot通用Shell启动脚本方式,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教

前言

Spring boot 通用启动脚本，包含启动，停止，重新启动，查看状态命令参数。

此脚本能自动寻找与脚本在目录下的jar包做为程序启动包。

自动检测java环境。

无需一定要在程序目录下执行脚本

Spring Boot Linux启动脚本

#!/bin/bash
SCRIPT_CALL_DIR=$(pwd)/
SCRIPT_FILENAME=${0##*/}
SCRIPT_DIR="$(dirname "$(readlink -f "$0")")/"
JAVA_CMD=`command -v java`
JAVA_OPTS="-Xms512m -Xmx512m -Dfile.encoding=utf-8"
#这里可替换为你自己的执行程序，其他代码无需更改，默认查找此脚本同目录jar文件，只取第一个
APP_NAME=`ls -l ${SCRIPT_DIR}|grep -e ".*[.]jar$"|head -n 1|awk '{print $9}'`
[ ! -z $APP_NAME ] && APP_NAME=$SCRIPT_DIR$APP_NAME
echo "============================================================"
echo "SCRIPT_CALL_DIR: $SCRIPT_CALL_DIR"
echo "SCRIPT_DIR:      $SCRIPT_DIR"
echo "SCRIPT_FILENAME: $SCRIPT_FILENAME"
echo "JAVA_CMD:        $JAVA_CMD"
echo "JAVA_OPTS:       $JAVA_OPTS"
echo "APP_NAME:        $APP_NAME"
echo "============================================================"
[ ! -e $JAVA_CMD ] && echo "没有安装java运行环境" && exit 1
[ -z $APP_NAME ] && echo "没有找到jar程序包" && exit 1
#使用说明，用来提示输入参数
usage() {
    echo "Usage: sh startup.sh [start|stop|restart|status]"
    exit 1
}
 
#检查程序是否在运行
is_exist(){
  pid=`ps -ef|grep $APP_NAME|grep -v grep|awk '{print $2}'`
  #如果不存在返回1，存在返回0     
  if [ -z "${pid}" ]; then
   return 1
  else
    return 0
  fi
}
 
#启动方法
start(){
  is_exist
  if [ $? -eq 0 ]; then
    echo "${APP_NAME} is already running. pid=${pid}"
  else
    #nohup java -jar ${APP_NAME} &
    #Xms Xmx  指定虚拟内存上下限
    #nohup java -jar ${APP_NAME} >csls.out 2>&1 &
	#nohup java -Xms512m -Xmx512m -Dfile.encoding=utf-8 -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=<ip>:<port> -Dspring.profiles.active=test -jar ${APP_NAME} > output.log 2>&1 &
	cd ${SCRIPT_DIR}
	# exec -c 创建新环境执行程序，如此便不用在程序目录下执行启动命令了
    exec -c nohup ${JAVA_CMD} ${JAVA_OPTS}  -jar ${APP_NAME} > /dev/null  2>&1 &
    is_exist
    if [ $? -eq 0 ]; then
      echo "${APP_NAME} is running success. pid=${pid}"
    fi
  fi
}
 
#停止方法
stop(){
  is_exist
  if [ $? -eq "0" ]; then
    kill -9 $pid
    is_exist
    if [ $? -eq 0 ]; then
      echo "${APP_NAME} still in the running. pid=${pid}"
    else
      echo "${APP_NAME} has stopped running."
    fi
  else
    echo "${APP_NAME} is not running"
  fi  
}
 
#输出运行状态
status(){
  is_exist
  if [ $? -eq "0" ]; then
    echo "${APP_NAME} is running. Pid is ${pid}"
  else
    echo "${APP_NAME} is NOT running."
  fi
}
 
#重启
restart(){
  stop
  start
}
 
#根据输入参数，选择执行对应方法，不输入则执行使用说明
case "$1" in
  "start")
    start
    ;;
  "stop")
    stop
    ;;
  "status")
    status
    ;;
  "restart")
    restart
    ;;
  *)
    usage
    ;;
esac

tip: IDEA 远程代码调适

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=<ip>:<port>

在这里插入图片描述

使用示例及说明

此脚本要与运行的springboot包放在同一目录下，目录结构如下

.
├── config
│   └── application.yml
├── data-batch-service.jar
└── startup.sh

运行sh startup.sh

sh startup.sh

结果如下

[dsp@tbase01 data-batch-service]$ sh startup.sh 
============================================================
