Pom.xml的依賴自動生成

1.第一種用引入jar包的方法

以上是整個檔案直接用idea打開即可      

1 import com.gugugu.maven.Poms;
 2 
 3 import java.io.IOException;
 4 
 5 /**

 8  **/
 9 public class PomTest1 {
10     public static void main(String[] args) throws IOException {
11         Poms.getPomXMl("E:\\後端筆記\\常用工具\\資料校驗\\lib");//jar包的位置
12     }
13 }      

2.第二種:測試類解決

無需其他jar包,隻需要測試類,
