hibernate基礎查詢一（動態組查詢條件）

String hql = "from   Items oi "
   + " where exists "
   + "( select 1 from Nodes n where oi.cId = n.cId and n.nodeId= ? )";
  List params = new ArrayList();
  params.add(nodeId);//固定參數信息
  
  //組拼查詢的 檢驗項目串
  if(null != existsItems && !"".equals(existsItems)){
   StringBuffer strbuf = new StringBuffer();
   strbuf.append(" and oi.ItemId not in ( ");//組成新的查詢條件
   String[] items = existsItems.split(",");
   for(int i=0;i<=items.length-1;i++){
    if(i != 0){
     strbuf.append(" , ");
    }
    strbuf.append(" ? ");//動態添加參數
    params.add(items[i]);//同步添加變量
   }
   strbuf.append(" )");
   hql += strbuf.toString();
  }
  List<Items> list = findListByHQL(hql, params);

public List<T> findListByHQL(final String hql,final List paramList){   return (List) getHibernateTemplate().execute(new HibernateCallback() {      public Object doInHibernate(Session session)      throws HibernateException, SQLException {     Query query = session.createQuery(hql);//建立Query對象     if(paramList!=null){      for(int i=0;i<paramList.size();i++){       query.setParameter(i, paramList.get(i));//真正複製      }     }     return (List<T>) query.list();//返回結果list數據    }   });  }
