spring boot打包部署到Linux环境

时间:2022-06-07 23:47:17

  打包部署说白了就两步:打包、部署。废话不多说,直接拿spring boot自动生成的项目骨架,再添加一个文件用来演示:

package com.crocodile.springboot;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class PDFController {
    @RequestMapping(value = "hello", method = RequestMethod.GET)
    public String helloWorld() {
        return "hello, world.";
    }
}

  还要在配置文件application.properties里加两个配置项:

#修改tomcat的默认的端口号,将8080改为8888
server.port=8888

#切换配置文件
spring.profiles.active=test

  最后打包,直接跑Maven生成jar包就好了。

  打完包就要部署了。因为spring boot有内置tomcat容器,这点比较方便,省去了tomcat的部署。我们直接把jar包扔到linux上。这里你可以通过FTP工具,也可以使用下面这个命令行的小工具,先安装:

  再上传:

rz -y
rz waiting to receive.
 zmodem trl+C ȡ

  它会弹出一个界面让你选择具体文件的,你选择maven打好的jar后点击发送就ok了。

  接着就是执行jar包,这里通过一个脚本来执行:

#!/bin/sh
JAR_NAME=springboot-0.0.1-SNAPSHOT.jar

tpid=`ps -ef|grep $JAR_NAME|grep -v grep|grep -v kill|awk '{print $2}'`
if [ ${tpid} ]; then
echo 'Stop Process...'
fi
sleep 5
tpid=`ps -ef|grep $JAR_NAME|grep -v grep|grep -v kill|awk '{print $2}'`
if [ ${tpid} ]; then
echo 'Kill Process!'
kill -9 $tpid
else
echo 'Stop Success!'
fi

tpid=`ps -ef|grep $JAR_NAME|grep -v grep|grep -v kill|awk '{print $2}'`
if [ ${tpid} ]; then
        echo 'App is running.'
else
        echo 'App is NOT running.'
fi

rm -f tpid
nohup java -jar ./$JAR_NAME --spring.profiles.active=test &
echo $! > tpid
echo 'Start Success!'

  这个脚本的作用就是通过jar命令来执行jar包,前面是先通过grep命令看是否已有jar包在跑,有的话就杀掉再拉起,没有就直接跑。注意上面的JAR_NAME需要根据你的jar包名称赋值。保存好脚本后还得给这个脚本加权限:

chmod +x start.sh

  打完收工,你可以直接用它跑了:

 ./start.sh 
Stop Process...
Kill Process!
App is NOT running.
Start Success!

  上面是我已经把jar起好了,再次执行start.sh后,它先停掉进程后又拉了起来。可以看下日志
