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 findAllAlbum(int id);
public List 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);
}
