下面实现数据库的连接，首先编写将分数写入数据库的方法，在src重新建一个包，包里写写入分数的方法。

package DAO;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;

import util.DBUtil;

public class DAO {
	/*
	 * 增加分数的方法
	 */
	public static void save(int score) throws Exception{
		PreparedStatement ps=null;
		Connection conn = null;
		try{
		conn = DBUtil.getConnection();
		String sql ="INSERT INTO mydb2(score) values(?)";
		ps = conn.prepareStatement(sql);
		ps.setInt(1,score);
		ps.executeUpdate();
		}catch(SQLException e){
			e.printStackTrace();
		}finally{
			DBUtil.close(conn);
		}
	}

}

然后连接数据库

package util;
 
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
 
public class DBUtil {
	public static void main(String[]args) throws Exception{
		Connection conn = DBUtil.getConnection();
		System.out.println(conn);
		DBUtil.close(conn);
	}
	public static void close(Connection conn){
		try{
			if(conn != null){
				conn.close();
			}
		}catch(SQLException e){
			e.printStackTrace();
		}
	}
	public static Connection getConnection() throws Exception{
		//System.out.println("112");
		Connection conn = null;
		//1.注册驱动（加载驱动）
		Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
		conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=数据库名字","sa", "********");
		
		//System.out.println("123");
		//		try{
//		Class.forName("com.microsoft.sqlserver.jdbc.Driver");
//		System.out.println("111");
//		//2.建立连接
//		conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1443/mydb2","sa","the1012secret");
//		System.out.println("111");
//		}catch(ClassNotFoundException e){
//			//System.out.println("注册驱动");
//		}catch(SQLException e){
//			e.printStackTrace();
//		}
		return conn;
	}
}
