首先有以下.jsf:
<ui:repeat var="prod" value="#{showProducts.decoys}">
<h:form>
{prod.price}
{prod.weight}
{prod.size} >
<h:commandButton value="Buy" action="shoppingCart"/>
</h:form>
</ui:repeat>
有以下shoppingCart.jsf:
<h:form>
<h:dataTable value="#{prod}">
<h:column>
#{prod.name}<br/>
</h:column>
<h:column>
#{prod.price}<br/>
</h:column>
<h:column>
<h:inputText value="#{prod.count}" size="3"/>
</h:column>
</h:dataTable>
<h:inputText value="#{order.phone}"/><br/>
<h:inputText value="#{order.mail}"><br/>
<h:inputText value="#{order.city}"/><br/>
<h:commandButton value="Order" action="#{showProducts.persistOrder}">
</h:form>
面配置:
<managed-bean>
<managed-bean-name>showProducts</managed-bean-name>
<managed-bean-class>main.ShowProducts</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
...
<managed-property>
<property-name>product</property-name>
<value>#{product}</value>
</managed-property>
</managed-bean>
<managed-bean>
<managed-bean-name>product</managed-bean-name>
<managed-bean-class>main.Product</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
...
问题是:
托管bean名称定义为
product
迭代是这样进行的(shoppingCart.jsf):
h:dataTable value="#{prod}">
所以这意味着这个迭代与名为
产品
无论如何
如何设置属性
prod.price,prod.weight,prod.count
对于真正的托管bean属性:
product.price,product.weight,product.size
