springboot的jar包方式

  • idea默认就是jar打包方式所以直接使用maven工具按照步骤点击就可以直接打包
  • ps:打包前你的数据库相关的连接信息要记得修改,不能再用本地的了

第二步Maven clean :清除编译后的目录,默认是target目录

[INFO] Scanning for projects...
[INFO]

第三步Maven package:打包

[INFO] --- maven-jar-plugin:3.1.0:jar (default-jar) @ cwgl ---
[INFO] Building jar: D:\FFM\cwgl\target\cwgl-0.0.1-SNAPSHOT.jar
[INFO]

[INFO] Finished at: 2020-05-27T11:11:24+08:00
[INFO] Final Memory: 43M/272M
[INFO] ------------------------------------------------------------------------

Process finished with exit code 0

第四步:到target目录下找到 jar包

第五步:将jar包放到linux的任意文件夹(可访问)下

第六步:输入 java -jar 文件名.jar

ps:这样有一个问题就是当你终端关闭后,就不能访问了,或者说隔一段时间后就不能访问了

如何解决这个问题呢 ?使用nohup

nohup java -jar 文件名.jar &

1、nohup的意思不挂服务,常驻的意思,除非云服务器重启,那就没法了;
2、最后一个&表示执行命令后要生成日志文件nohup.out=

出现:nohup: ignoring input and appending output to ‘nohup.out’
正常情况,显目启动成功

检测:最后在浏览器地址栏输入项目地址,检查项目是否部署成功
