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。
<code class="language-java">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); } } }</code>
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; } }
