在Struts2中，使用绑定select进行页面查询

  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>
