使用绑定数据的select框作为查询条件进行列表查询参考小例子

1 自定义下拉框Vo对象

publicclass GameNameSelectVO {     private String id; //游戏名称ID    private String gameName; //游戏名称     public String getId() {       return id;    }    public voidsetId(String id) {       this.id = id;    }    public String getGameName() {       return gameName;    }    public voidsetGameName(String gameName) {       this.gameName = gameName;    }}

2 Action 作为查询控制器

privateList<GameNameSelectVO> gameNameList;   //页面游戏名称下拉对象集合private String gameNameID;            //游戏名称需要提供get set方法

方法

/** * 进入游戏参数查询页面 * @return */@SuppressWarnings("unchecked")public String toParameterPage(){//获得省份信息fundvo = gameInfoMonitorService.getProvinceInfo(String.valueOf(pid));if(null == gameNameID){gameNameID = "0";//初始查询全部}//获得游戏名称下拉数据集合gameNameList = gameInfoMonitorService.getGameNameSelectList();//得到每页记录数PropertyUtil p = new PropertyUtil();int pageSize = Integer.parseInt(p.getProperty("/system.properties", "account.alarm.pageSize"));// 获得查询记录总数int count = gameInfoMonitorService.getParameterListCount();// 根据总记录数、每页记录数、当前页码生成分页对象page = new Page<GameInfoPageVO>(count, pageSize, getCurrentPage());gameInfoVOList = gameInfoMonitorService.getParameterList(gameNameID,page.getCurrentPage(),page.getPageSize());return "parameterPage";}

3 Impl 实现类

    /**     * 获得游戏名称下拉集合     */    public List<GameNameSelectVO>getGameNameSelectList() {       StringBuffer hql = new StringBuffer();       hql.append(" select rd.id,rd.game_name fromT_RCVD_GAME_DEFINITION rd " );       List<GameNameSelectVO>  volist = new ArrayList<GameNameSelectVO>();       try{           List list = hibernateDao.queryBySql(hql.toString());                     for(Iterator it =list.iterator();it.hasNext();){              Object [] objs = (Object[])it.next();              GameNameSelectVO vo = new GameNameSelectVO();              vo.setId(objs[0].toString());              vo.setGameName(objs[1].toString());              volist.add(vo);           }       }catch(Exception e){e.printStackTrace();}           return volist;    }

4 JSP页面

     <div class="searchtime">            游戏名称：<select name="gameNameID" id="" style="width: 10%;"  >                             <option value="0">--全部--</option>                             <s:iterator value="gameNameList"  var="gameNameVo">                                   <option  value="<s:property value="id"/>" <c:if test="${gameNameVo.id eq gameNameID }" >selected</c:if> >   <s:property value="gameName"/></option>                             </s:iterator>               </select>             <input type="submit" value="查询" class="button"/>           </div>
