Java 将JDBC与SQLServer2008连接

我使用以下代码将我的java应用程序连接到SQLServer2008

//connecting java with a different database management system
import java.sql.*;
import java.util.Scanner;

public class MyDatabase {

    static Connection conn = null;
    static PreparedStatement ps = null;

    public static void main(String [] arg) {
        String urlp1, urlp2, urlp3;
        urlp1 = "jdbc:sqlserver://;";
        urlp2 = "servername=HP-PC" + "\\" + "MYINSTANCE;integratedSecurity=true;";
        String url = urlp1 + urlp2;
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        }
        catch (Exception e) {
            System.out.println("Exception 1");
            e.printStackTrace();
        }
        try {
            conn = DriverManager.getConnection(url, "sa", "admin");
        }
        catch (Exception ec) {
            System.out.println("Exception 1 Part 2");
            ec.printStackTrace();
        }
        try {
            System.out.println("Enter name:");
            Scanner scan = new Scanner(System.in);
            String name = scan.nextLine();
            System.out.println("Enter age:");
            int age = scan.nextInt();
            String query = "insert into table1(Stuname,Age) values(?,?);";
            ps = conn.prepareStatement(query);
            ps.setString(1, name);
            ps.setInt(2, age);
            conn.commit();
        }
        catch (Exception e1) {
            System.out.println("Exception 2");
            e1.printStackTrace();
        }
        finally {
            try {
                System.out.println("Closed!!!");
                conn.close();
            }
            catch (Exception e2) {
                System.out.println("Exception 3");
                e2.printStackTrace();
            }
        }
    }
}

我已经下载了“sqljdbc4.0.jar”文件，并在cmd中使用以下命令来定位SQLServerDriver类的地址：

设置类路径=。；D:\Java\jre\bin\Microsoft JDBC Driver 4.0 for SQL Server\sqljdbc_4.0\chs\sqljdbc4.jar

问题是表中没有输入数据。未显示任何错误或异常。 我已经在互联网上找到了很多解决方案，但没有一个有效。

我怎样才能做到这一点呢？

我想你没有任何联系

 System.out.println("Enter name:");
        Scanner scan=new Scanner(System.in);
        String name=scan.nextLine();
        System.out.println("Enter age:");
        int age=scan.nextInt();
        String query="insert into table1(Stuname,Age) values(?,?);";
        ps=conn.prepareStatement(query);
        ps.setString(1,name);
        ps.setInt(2,age);

       // you have forget to submit your changes to the database. try with following line of code
        ps.execute() or ps.executeQuery()

        conn.commit();

我认为URl是不正确的，看到这个了吗？你看到控制台上打印了什么输出？你真的接通了吗？
