jsp实现仿QQ空间新建多个相册名称并向相册中添加照片功能

(编辑：jimmy 日期: 2024/12/25 浏览：3 次 )

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。

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：

public class UpDAOImpl implements UpDAO { 
 /* (non-Javadoc) 
 * @see cn.jvsun.DAO.UpDAO#creAlbum(cn.jvsun.POJO.AlbumPOJO)

  pstate = conn.prepareStatement(sql); 
  pstate.setInt(1, albumNum); 
  pstate.setString(2,ap.getA_name()); 
  pstate.setInt(3, ap.getUser_id());
