生成模拟数据

使用jdbc连接数据库添加数据，相关删除 ，修改也可以使用此方法。

导入所需mysql-jdbc jar包 

<!-- mysql-jdbc连接 -->
    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.6</version>
    </dependency>

package cn.cllover.administration.test;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

//逻辑生成虚拟数据
