java连接MySql JDBC的简单例子

发现有好多同学在初学java JDBC 是面临着的最大难题是无法连接到Sql数据库，在这里写一个基于JDK9.0  JDBC8.0.11 MySQl8.0的一个于连接数据库的简单小例子

import java.sql.*;

public class Demo1 {

	Connection con;

	public void run() {

		try {
			Class.forName("com.mysql.cj.jdbc.Driver");
			System.out.println("注册驱动成功");

			this.con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8", "root", "111111");

			System.out.println("JDBC已连接");

			Statement st = con.createStatement();
			ResultSet rs = st.executeQuery(" select * from stu");
			while (rs.next()) {
				int id = rs.getInt("id");
				String name = rs.getString("name");
				int age = rs.getInt("age");

				System.out.println(id + "  " + name + "   " + age);

			}
			rs.close();
			st.close();
			con.close();

		} catch (Exception e) {

			System.out.println(e);
		}
	}

	public static void main(String[] args) {

		Demo1 d = new Demo1();
		d.run();

	}

}
