学习javaweb中关于配置编写Maven原始pom.xml文件

今天学习Maven的时候，因为是跟随的b站上的javaweb的一个课程，当up主直接复制pom.xml文件时。视频前的大家都傻眼了。。。于是老实人只能手敲上去。。
但是在编译阶段就出了大问题。

百思不得其解，到CSDN查询过后，发现是pom.xml文件配置错误，看了很多博主的解决办法， 只有一个给我看进去了。因为我本身知道自己是手敲的，可能会存在问题，于是果断选择寻找原始pom.xml文件
寻找结果如下:

    4.0.0
    //groupId是你这个maven项目的id，需要改成相同的名称。
    com.xxxx
    SSM_Stuct
    1.0-SNAPSHOT

经配置过后，编译结果。
