我用java編寫了一個圖書館管理系統(tǒng)，實現(xiàn)了通過I/O流存儲，但是想通過數(shù)據(jù)庫存儲。

倒數(shù)據(jù)庫連接類jar包以SQL Server 2005 為例：

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

public class ConnectionUtil {

private static String DRIVER = "com.microsoft.sqlserver.jdbc.SQLServerDriver";

private static String URL = "jdbc:sqlserver://127.0.0.1:1433;databaseName=數(shù)據(jù)庫名";// 127.0.0.1

private static String USERNAME = "登錄名";

private static String PASSWORD = "登錄密碼";

private static Connection CON = null;

public static Connection openConnection() {

try {

Class.forName(DRIVER);

CON = DriverManager.getConnection(URL, USERNAME, PASSWORD);

} catch (ClassNotFoundException e) {
