删除相册及其图片的实现方法

@Override
public String deleteAlbum(String[] ids) {
    StringBuilder deleteNames = new StringBuilder();
    if (ids == null || ids.length == 0) {
        return deleteNames.toString();
    }
    for (String id : ids) {
        PhotoAlbum bean = this.loadAlbum(id);
        //删除相册
        this.photoAlbumDao.delete(bean);
        // 删除图片
        // 获取相册下的图片附件
        List<SysAttach> attaches = this.attachService.selectAttachList("com.operate.entity.PhotoAlbum", id);
        // 获取附件ids
        String[] attachIds = new String[attaches.size()];
        int i = 0;
        for(SysAttach arr: attaches) {
            attachIds[i++] = arr.getAttachId();
        }
        // 删除图片附件
        this.attachService.deleteAttach(attachIds);
        //返回删除的相册名称
        deleteNames.append(bean.getTitle()).append(" 、");
    }
    if (deleteNames.length() > 0) {
        deleteNames.deleteCharAt(deleteNames.length() - 1);
    }
    return deleteNames.toString();
