dao层模板

List<Object> listParam = new ArrayList<Object>();

    StringBuffer sql = new StringBuffer();

    sql.append("SELECT ");  

    Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();

SQLQuery query = session.createSQLQuery(sql.toString());

for (int i = 0; i < listParam.size(); i++) {

query.setParameter(i, listParam.get(i));

}

List<Object> list = query.list();

//query.executeUpdate(caption);

for (Iterator iterator = list.iterator(); iterator.hasNext();) {

Object[] object = (Object[]) iterator.next();

if(object[0] != null){

String caption = (String) object[1];

voDevice.setCaption(caption);

}

}

在dao层取数字值

String rate = object[0].toString();

voCameraRec.setDataType(((Number)objs[3]).longValue());

取后台dao数字转字符串类型

String.valueOf(((Number)(obj[39])).longValue())
