使用Github Action来自动化构建Maven项目

简介

本文主要介绍如何把Github仓库中的Maven项目通过Github Action进行自动化构建后生成Jar包，接着拷贝到服务器进行部署。

服务器脚本

• 脚本application.sh用于启停应用:

  #!/bin/bash
  
  # application jar's name
  appDir=~/java_deploy
  application=$(find $appDir -type f -name "*.jar") 
  
  ## determine existence of processus of application
  isExist(){
      ## check pid
      pid=`ps -ef | grep ${application} | grep -v grep | awk '{print $2}'`
      ## if pid not exist return 0 else 1
      if [ -z "${pid}" ]; then
          return 0
      else
          return 1
      fi
  }
  
  log=$appDir/application.log
  
  ## start application in background and generate appDir/application.log
  function start()
  {
      ## deermine existence of processus
      isExist
      ## if not running
      if [ $? -eq "0" ]; then
          echo "Your ${application} is not running"
          nohup java -jar $application --spring.profiles.active=test > $log &
          echo "${application} startup success"
      else
          echo "${application} is running, pid=${pid} "
      fi
  }
  
  ## stop the processus application
  function stop()
  {
      isExist
      ## if not exist - ok
      if [ $? -eq "0" ]; then
          echo "${application} is not running"
      else
          echo "${application} is running, pid=${pid}, prepare kill it "
          # if exist - kill the processus
          kill -9 ${pid}
          echo "${application} has been successfully killed"
      fi
  }
  
  ## check status
  function status()
  {
      appPid=`ps -ef |grep java|grep $application |awk '{print $2}'`
      if [ -z $appPid ]; then
          echo -e "Not running " 
      else
          echo -e "Running [$appPid] " 
      fi
  }
  
  ## restart
  function restart(){
      stop
      start
  }
  
  ## arg
  case "$1" in
      "start")
          start
          ;;
      "stop")
          stop
          ;;
      "restart")
          restart
          ;;
      "status")
          status
          ;;	
      *)
          echo "please enter the correct commands: "
          echo "such as : sh application.sh [ start | stop | restart |status ]"
          ;;
  esac
