Spring DAO的編寫：
利用hibernate提供的Query的setFirstResult和setMaxResults方法進(jìn)行數(shù)據(jù)分頁,程序中以我建立的用戶表為例，query的分頁機(jī)制是以跳指針的方式進(jìn)行數(shù)據(jù)讀取，這樣極大的提高的數(shù)據(jù)分頁程序的響應(yīng)速度
//分頁主程序
       public List getUsersPage(int firstResults,int maxResults){
              try {
                     Session session=this.getSession();
                     Query query=session.createQuery("from SYSUSERS sysusers order by sysusers.username asc");
                     query.setFirstResult(firstResults);
                     query.setMaxResults(maxResults);
                     return query.list();
              } catch (HibernateException e) {
                     // TODO 自動生成 catch 塊
                     e.printStackTrace();
              }
              finally{
                     try {
                            session.close();
                     } catch (HibernateException e) {
                            // TODO 自動生成 catch 塊
                            e.printStackTrace();
                     }
              }
              return null;
       }
       //顯示分頁總頁數(shù)
       public String getPageCount(int maxResults){
              String pageCount="0";
              try {
                     session=this.getSession();
                     Query query=session.createQuery("select count(sysusers.id) from SYSUSERS sysusers");
                     int Count=((Integer)query.list().get(0)).intValue();
                     if(Count%maxResults>0){
                            pageCount=String.valueOf(Count/maxResults+1);
                     }
                     else{
                            pageCount=String.valueOf(Count/maxResults);
                     }
                     return String.valueOf(pageCount);
              } catch (HibernateException e) {
                     // TODO 自動生成 catch 塊
                     e.printStackTrace();
              }
              finally{
                     try {
                            session.close();
                     } catch (HibernateException e) {
                            // TODO 自動生成 catch 塊
                            e.printStackTrace();
                     }
              }
              return pageCount;
       }
       //顯示總記錄數(shù)
       public String getTotalMark(){
              String totalMark="0";
              try {
                     session=this.getSession();
                     Query query=session.createQuery("select count(sysusers.id) from SYSUSERS sysusers");
                     int Count=((Integer)query.list().get(0)).intValue();
                     totalMark=String.valueOf(Count);
                     return totalMark;
              } catch (HibernateException e) {
                     // TODO 自動生成 catch 塊
                     e.printStackTrace();
              }
              finally{
                     try {
                            session.close();
                     } catch (HibernateException e) {
                            // TODO 自動生成 catch 塊
                            e.printStackTrace();
                     }
              }
              return totalMark;
       }
 
寫完spring的dao之后定義相應(yīng)的接口，這里不在復(fù)述
在這個(gè)dao寫好之后，就可以在相應(yīng)的表示層中進(jìn)行方法調(diào)用，達(dá)到分頁的目的
