写一个简单的登录,数据库只有一张表,我想知道怎么实现与数据库的连接,谁能给个完整的例子,不用任何框架写

网上这样的例子太多了啊~随便搜一个都可以用的~比如这个（别人的哈我只是随手搜来给你看看）http://blog.csdn.net/linkt/article/details/6406721
别忘了改数据库Url和table名什么的哈~
主要是确保下载并导入了ojdbc的jar包就好，连接语句和其他语言没差太多~
就是这样，喵~

- Java code
package zmy.db;import java.sql.*;public class DBUtil { public static Connection getConnection() { Connection conn = null; try { String driver = "oracle.jdbc.driver.OracleDriver"; String dbName = "dbname"; String dbURL = "jdbc:oracle:thin:@localhost:1521:"; String username = "scott"; String password = "triger"; Class.forName(driver).newInstance(); conn = DriverManager.getConnection(dbURL + dbName, username, password); } catch (SQLException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } return conn; } public static boolean closeConnection(Connection conn) { try { conn.close(); return true; } catch (SQLException e) { e.printStackTrace(); return false; } catch (Exception e) { e.printStackTrace(); return false; } }}
