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; } }以上是“Java如何实现飞机大战”这篇文章的所有内容,感谢各位的阅读!相信大家都有了一定的了解,希望分享的内容对大家有所帮助,如果还想学习更多知识,欢迎关注创新互联行业资讯频道!
