dao 表优化

//列表ticket 底层hql语言 可以去掉一些字段 比如简介
String hql = "select new Ticket(id,name,address,activeDate,saleBeginTime,saleEndTime,thumbnail,pic,enteringman,enteringdate,status,datasource) from "+table+" where status = '已审核' order by "+orderby+" "+desc;

   
ticket方法重载
public Ticket(Integer id, String name, String address, String activeDate, Object saleBeginTime, Object saleEndTime,
			String thumbnail, String pic, String enteringman,
			Object enteringdate, String status, String datasource) {
		super();
		this.id = id;
		this.name = name;
		this.address = address;
		this.activeDate = activeDate;
		this.saleBeginTime = stringToTimestamp(saleBeginTime.toString());
		this.saleEndTime = stringToTimestamp(saleEndTime.toString());
		this.thumbnail = thumbnail;
		this.pic = pic;
		this.enteringman = enteringman;
		this.enteringdate = stringToTimestamp(enteringdate.toString());
		this.status = status;
		this.datasource = datasource;
	}
    
    // Property accessors
