实现功能介绍：
主要是新建相册，可以建多个相册，在相册中添加多张照片，删除照片，删除相册，当相册下有照片时先删除照片才能删除相册。
因为每个相册和照片要有所属人，所以顺带有登录功能。
声明：只是后端实现代码，前台无任何样式，代码测试可行，仅供参考。

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，要修改图片名称，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，修改图片名的帮助类：
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(); } } 实现所有这些的接口类：
public interface UpDAO { /** * 创建相册名称 * */ public int creAlbum(AlbumPOJO ap); /** *显示所创建的所有相册名称 */ public List<AlbumPOJO> findAllAlbum(int id); public List<PhotoPOJO> findAllPhoto(int id); /** * 上传照片 */ public int upPhoto(PhotoPOJO pp); /** * 删除相册 * @param id 相册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); } 接口的具体实现类：
