JSP中通过JDBC访问数据库

public void getData(){
        String URL = "jdbc:sqlserver://127.0.0.1:1433;databaseName=news";
        Connection con=null;
        try {
            // 加载驱动
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            // 获得数据库连接对象
            con = DriverManager.getConnection(URL, "sa", "12345yehuan");
            // 执行sql语句
            String sql = "select * from student";
            Statement statement = con.createStatement();
            // 接收查询结果
            ResultSet rs = statement.executeQuery(sql);
            while(rs.next()){
                int id = rs.getInt(1);
                String name = rs.getString(2);
                int age = rs.getInt(3);
                System.out.println(id+"\t"+name+"\t"+age);
            }
            System.out.println("连接成功");
            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } finally {    
                try {
                    // 释放资源
                    con.close();
                } catch (SQLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
        }
