Java通过jdbc连接Mysql数据库

import java.sql.Connection;

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

public class Demo2 {

public static void main(String[] args) throws SQLException, ClassNotFoundException{
String url ="jdbc:mysql://localhost:3306/day14";
String user="root";
String password="root";

//1.加载驱动
Class.forName("com.mysql.jdbc.Driver");

//2.获取与数据库的连接
Connection conn = DriverManager.getConnection(url, user, password);

//3.获取用于向数据库发送sql的statement
Statement st = conn.createStatement();

//4.向数据发送sql
String sql = "select * from users";
ResultSet rs = st.executeQuery(sql);

//5.取出结果集的数据
while(rs.next()){
System.out.println("id= "+rs.getObject("id"));
System.out.println("name= "+rs.getObject("name"));
System.out.println("password= "+rs.getObject("password"));
System.out.println("email= "+rs.getObject("email"));
System.out.println("birthday= "+rs.getObject("birthday"));
}

//6.关闭连接
rs.close();
st.close();
conn.close();
}
}
