idea 创建项目的完整流程

1，idae创建maven项目

https://blog.csdn.net/qq_37952161/article/details/80293507

2，IDEA右键新建时没有Java Class选项

3.maven在打包的时候会碰到一些问题，

 3.1 注意每次打包的时候编译一遍，执行下代码。

 3.2 需要添加的pom中

   注意 jar 包，注意main，注意私有服务

idea jar包，

Linux上输出日志：
1,打好jar包后，再Linux上执行，命令如下：
nohup java -jar BiuBiuBiu.jar >output 2>&1 &
2.当从idea上通过maven 打好jar包后，通过nohup 执行的时候，请注意。output 就是你执行的日志所在文件
3.通过tailf -n 100 进行查看。
4，如果想输出日志，直接通再idea上System.out.println("") 即可。
5.如果 需要 java -jar 传参数。需要再执行的旁边添加参数。

6。打jar包的时候不要忘记编译一遍，执行下代码即可。
