jsp实现仿QQ空间新建多个相冊名称,向相冊中加入照片
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);
}
