Hybris：如何将类作为参数传递给 cms:component？

Question

I've started to learn Hybris and I want to find out how to pass the class as a parameter to a custom CMS Component (for the component's root element).

Let's suppose that in a jsp file named customNavigationComponent.jsp I have this piece of code:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="cms" uri="http://hybris.com/tld/cmstags"%>

<c:forEach items="${navigation.entries}" var="navigationLink">
    <div class="custom-component-wrapper">
        <cms:component component="${navigationLink.item}"/>
    </div>
</c:forEach>

And the custom component looks like this:

<a href="${component.url}">
    <div>${component.linkText}</div>
</a>

I would like to understand what I need to do to pass the class navigation-link as a parameter, like this:

<cms:component component="${navigationLink.item}" class="navigation-link"/>

so that the rendered result will be similar to:

<a href="stackoverflow.com" class="navigation-link">
    <div>Lorem Ipsum</div>
</a>

Answer 1

There is no attribute called, class in cms:component and therefore the following statement will not work:

<cms:component component="${navigationLink.item}" class="navigation-link"/>

Please check https://help.sap.com/doc/a4265d5ea8314eb2929e6cf6fb8e35a5/1811/en-US/de/hybris/platform/cms2lib/cmstags/CMSComponentTag.html

In order to understand it better, you can compare it with c:forEach . At https://docs.oracle.com/javaee/5/jstl/1.1/docs/tlddocs/c/forEach.html , you will find a list of attributes available with c:forEach and if you want to dig deeper, you can further check https://tomcat.apache.org/taglibs/standard/apidocs/javax/servlet/jsp/jstl/core/LoopTagSupport.html

If you want to use your statement, you will need to create a custom tag.
