从xml中提取数据后，数据必须存储在SQL数据库中

Question

我编写了从 xml 中提取数据并提供以下输出的 Java 程序。 提取完成后，数据必须存储在 SQL 数据库中。请帮我在SQL数据库中添加数据，

以下输出必须存储在数据库中，

输出：-

Root element of the doc is geodata
Total no of people : 2
Address : 2344 States Drive, MA 01213, USA
Phone Number : 333-222-2222
Salary : $3000
Pension : $3000
Address : 2345 Gates Drive, PA 11213, USA
Phone Number : 444-222-2222
Salary : $3500
Pension : $3500

创建一个方法，说 insert(root,noOfPeople,Address,phNo,salary) 并将您要插入的所有数据以参数值一一传递到数据库中，以便逐行插入

数据库中的第 1 行将是 -

   Address : 2344 States Drive, MA 01213, USA
   Phone Number : 333-222-2222
   Salary : $3000
   Pension : $3000

数据中的第 2 行将是 -

Address : 2345 Gates Drive, PA 11213, USA
Phone Number : 444-222-2222
Salary : $3500
Pension : $3500

如果您不知道如何存储数据，请在 java 中读取 JDBC。 你也可以试试 1.How to store data in Java? Database? 2.http://www.tutorialspoint.com/jdbc/jdbc-db-connections.htm 3.http://www.tutorialspoint.com/jdbc/jdbc-insert-records.htm
