[JSF]使用DataModel处理表行事件的实例代码

复制代码 代码如下:

<f:view>
<h:form>
...
<h:dataTablevalue="#{Goods.goodsList}"var="goods">
<h:column>
<f:facetname="header">
<h:outputTextvalue="Name"/>
<h:commandLintaction="#{Goods.select}"immediate="true">
<h:outputTextvalue="#{goods.name}"/>
</h:commandLink>
</h:column>
...
</h:form>
</f:view>

复制代码 代码如下:

publicclassGoods{
....
privateDateModelgoodsList;
...
publicDataModelgetGoodsList(){
if(goodsList==null){
goodsList=newDataModel();
}
goodsList.setWrappedData(getRealGoodsList());//这里通过Service层或者Dao层访问到数据库
retrungoodsList;
}
publicStringselect(){
GoodsselectedGoods=(Goods)goodsList.getRowData();
setSelectedGoods(selectedGoods);
return"success";
}
