jsp实现仿QQ空间新建多个相冊名称，向相冊中加入照片

2024-11-18 00:40:01 202人阅读

工具：Eclipse，Oracle，smartupload.jar。语言：jsp，Java；数据存储：Oracle。

实现功能介绍：

主要是新建相冊，能够建多个相冊，在相冊中加入多张照片，删除照片，删除相冊，当相冊下有照片时先删除照片才干删除相冊。

由于每一个相冊和照片要有所属人。所以顺带有登录功能。

声明：仅仅是后端实现代码，前台无不论什么样式，代码測试可行，仅供參考。

代码：

数据库连接帮助类：

public class JDBCHelper {
	public static final String DRIVER = "oracle.jdbc.driver.OracleDriver";
	public static final String URL = "jdbc:oracle:thin:@localhost:1521:xxxx";
	public static final String DBNAME = "scott";
	public static final String PASSWORD = "xxxx";
	public static Connection getConn() throws Exception{
		Class.forName(DRIVER);
		Connection conn = DriverManager.getConnection(URL, DBNAME, PASSWORD);
		return conn;
	}
}

图片上传时，要改动图片名称，防止上传重名图片将上一张覆盖，这里的做法是将图片名改为由用户ID和精确到毫秒的时间组成。改动图片名的帮助类：

public class PhotoName {
	private String ip;

	public PhotoName(String ip) {
		super();
		this.ip = ip;
	}

	public String getIp() {
		return ip;
	}

	public void setIp(String ip) {
		this.ip = ip;
	}
	public String getTime(){
		Date date = new Date();
		DateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS");
		return df.format(date);
	}
	public String getPhotoName(){
		return this.ip + this.getTime();
	}

}

实现全部这些的接口类：

public interface UpDAO {
	/**
	 * 创建相冊名称
	 * 
	 */
	public int creAlbum(AlbumPOJO ap);
	/**
	 *显示所创建的全部相冊名称
	 */
	public List<AlbumPOJO> findAllAlbum(int id);
	public List<PhotoPOJO> findAllPhoto(int id);
	/**
	 * 上传照片
	 */
	public int upPhoto(PhotoPOJO pp);
	/**
	 * 删除相冊
	 * @param id 相冊id
	 * @return
	 */
	public int delAlbum(int id);
	/**
	 * 删除照片
	 * @param id 照片id
	 * @return
	 */
	public int delPhoto(int id);
	/**
	 * 登录
	 * @param username
	 * @param password
	 * @return
	 */
	public UserPOJO login(String username,String password);
}

好了，全部代码就写完了。切记。须要smartupload.jar包，没有的童鞋能够去下载：http://download.csdn.net/detail/weixin_36380516/9807953
不积硅步无以至千里。努力。
