Q1：数据库
由于数据有点多，我们在这就不展示了（需要的联系我，我发给你）
i
这是里面所用到的一些架包，包等等。相信大家对这一块都已经了解了，我就不说废话了。

Q9:配置文件
DBDRIVER=com.mysql.jdbc.Driver DBURL=jdbc:mysql://localhost:3306/areadb?serverTimezone=GMT%2B8 DBUSER=root DBPWD=
注意：此数据库使用的是MySql数据库
该有的代码我都贴了，除了一些架包，这个，需要的q我，我发给你。
结果:
输入身份证号码后，当然这里我的身份证号码被我去掉了，你懂的！
这样，在今后项目中，给用户的体验感就会很强，只需要身份证号码就行。
