Question

我正在使用包含页面，并希望将对象的ID从主页面传递到包含页面的后端。

我试过这个

<ui:include src="/fleetreport/vehicledocument_list.xhtml">                      
    <ui:param name="fleetvehicleid" value="#{contractDetail.contract.fleetVehicleId}"/>
</ui:include>

在vehicledocument_list.xhtml的支持中

Map<String, String> params = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();
if (params.get("fleetvehicleid") != null) {
    fleetVehicleId = new Integer(params.get("fleetvehicleid"));
}

但是params.get（＆＃34; fleetvehicleid＆＃34;）始终为空。

有没有办法将这个id参数传递给bean？

Answer 1

FaceletContext faceletContext = (FaceletContext) FacesContext.getCurrentInstance().getAttributes().get(FaceletContext.FACELET_CONTEXT_KEY);
Object p1 = faceletContext.getAttribute("fleetvehicleid");

看起来类似的问题 How to retrieve value of a ui:param in the backing bean

使用include将参数传递给backing bean
