idea 建立項目的完整流程

1，idae建立maven項目

2，IDEA右鍵建立時沒有Java Class選項

3.maven在打包的時候會碰到一些問題，

 3.1 注意每次打包的時候編譯一遍，執行下代碼。

 3.2 需要添加的pom中

   注意 jar 包，注意main，注意私有服務

idea jar包，

Linux上輸出日志：

1,打好jar包後，再Linux上執行，指令如下：

nohup java -jar BiuBiuBiu.jar >output 2>&1 &

2.當從idea上通過maven 打好jar包後，通過nohup 執行的時候，請注意。output 就是你執行的日志所在檔案

3.通過tailf -n 100 進行檢視。

4，如果想輸出日志，直接通再idea上System.out.println("") 即可。

5.如果 需要 java -jar 傳參數。需要再執行的旁邊添加參數。

6。打jar包的時候不要忘記編譯一遍，執行下代碼即可。
