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。
packageDAO;
importjava.sql.Connection;
importjava.sql.PreparedStatement;
importjava.sql.SQLException;
importutil.DBUtil;
publicclassDAO{
/*
*增加分数的方法
*/
publicstaticvoidsave(intscore)throwsException{
PreparedStatementps=null;
Connectionconn=null;
try{
conn=DBUtil.getConnection();
Stringsql="INSERTINTOmydb2(score)values(?)";
ps=conn.prepareStatement(sql);
ps.setInt(1,score);
ps.executeUpdate();
}catch(SQLExceptione){
e.printStackTrace();
}finally{
DBUtil.close(conn);
}
}
}
然后连接数据库
packageutil;
importjava.sql.Connection;
importjava.sql.DriverManager;
importjava.sql.SQLException;
publicclassDBUtil{
publicstaticvoidmain(String[]args)throwsException{
Connectionconn=DBUtil.getConnection();
System.out.println(conn);
DBUtil.close(conn);
}
publicstaticvoidclose(Connectionconn){
try{
if(conn!=null){
conn.close();
}
}catch(SQLExceptione){
e.printStackTrace();
}
}
publicstaticConnectiongetConnection()throwsException{
//System.out.println("112");
Connectionconn=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(ClassNotFoundExceptione){
// //System.out.println("注册驱动");
// }catch(SQLExceptione){
// e.printStackTrace();
// }
returnconn;
}
}
