转 OFBIZ 网站或店铺视觉主题（visual Theme）设计

what   why

v.在ofbiz中的应用的主题是可以通过数据来配置的，在webtools 组件中的catalog,  content 菜单下可分别设置店铺和网站的主题。且ofbiz在设计前端页面时，不使用table之类的html元素进行布局，而是大量使用div元素进行布局。 这样可以为一个网站或店铺设置多种不同的视觉风格，同时做到html中内容和风格的分离，提高开发效率及可维护性。

how

v.在ofbiz 中的ecommerce 示例中网站的主题是根据一个action 中的 service 的得到的。 而这个Service 使用mini 语言实现的。

在Ecommerce 下的CommonScreens.xml#main-decorator   action 中通过service 标签调用 mini 语言实现的服务。

<script location="component://ecommerce/widget/EcommerceSetup.groovy"/>  
<!-- Get the store VisualTheme -->  
<set field="visualThemeId" from-field="productStore.visualThemeId" default-value="EC_DEFAULT"/>  
<SPAN style="COLOR: #ff0000">
	<service service-name="getVisualThemeResources">
</SPAN>  
<field-map field-name="visualThemeId"/>  
<field-map field-name="themeResources" from-field="layoutSettings"/>  
</service>  
<set field="layoutSettings" from-field="themeResources" default-value="${layoutSettings}" global="true"/>  
<set field="headerTemplateLocation" from-field="layoutSettings.VT_HDR_TMPLT_LOC[0]" default-value="component://ecommerce/webapp/ecommerce/includes/header.ftl"/>  
<set field="footerTemplateLocation" from-field="layoutSettings.VT_FTR_TMPLT_LOC[0]" default-value="component://ecommerce/webapp/ecommerce/includes/footer.ftl"/>  

<script location="component://ecommerce/widget/EcommerceSetup.groovy"/>

<!-- Get the store VisualTheme -->
<set field="visualThemeId" from-field="productStore.visualThemeId" default-value="EC_DEFAULT"/>
<service service-name="getVisualThemeResources">
	<field-map field-name="visualThemeId"/>
	<field-map field-name="themeResources" from-field="layoutSettings"/>
</service>
<set field="layoutSettings" from-field="themeResources" default-value="${layoutSettings}" global="true"/>
<set field="headerTemplateLocation" from-field="layoutSettings.VT_HDR_TMPLT_LOC[0]" default-value="component://ecommerce/webapp/ecommerce/includes/header.ftl"/>
<set field="footerTemplateLocation" from-field="layoutSettings.VT_FTR_TMPLT_LOC[0]" default-value="component://ecommerce/webapp/ecommerce/includes/footer.ftl"/>

mini 语言实现的服务在ofbiz\framework\common\script\org\ofbiz\common\CommonServices.xml 中。
