Registering non-entity beans

Registering non-entity beans

To register a non-entity beans, you add the bean definition to your extension project's <webapp>-plugin.xml, located in src/main/resources/META-INF/conf. If you're overriding an existing bean definition, make sure the bean ID is the same as the original and that the class points to your extension class.

For example, ep-core\src\main\resources\spring\service\service.xml contains the following bean definition for productXmlService:

	<bean id="productXmlService" class="com.elasticpath.service.catalog.impl.ProductXmlServiceImpl">
		<property name="productLookup" ref="productLookup"/commerce-legacy/>
		<property name="categoryLookup" ref="categoryLookup"/commerce-legacy/>
		<property name="beanFactory" ref="coreBeanFactory"/commerce-legacy/>


You have overridden this with this custom class com.extensions.service.catalog.impl.MyProductXmlServiceImpl. To enable your overridden service, you need to add the following bean definition to the ep-core-plugin.xml of your core extension:

<bean id="productXmlService"
    <property name="productLookup">
        <ref bean="productLookup" />
    <property name="categoryLookup">
        <ref bean="categoryLookup" />
    <property name="beanFactory">
        <ref bean="coreBeanFactory" />

If your service only applies to a specific webapp project, you only need to add it to that <webapp>-plugin.xml.

Note: Bean Definition Clutter

Continually adding bean definitions to <webapp>-plugin.xml can lead to clutter. By using the import mechanism, you can store your custom and override bean definitions in files within a directory structure that mirrors the out-of-the-box application. For example, to override, bean definitions in storefront's serviceSF.xml and url-mapping.xml, recreate the directory structure of the OOTB project under conf and create Spring configuration files with the same names in the appropriate locations. Then import them into ep-storefront-plugin.xml as follows:

    <import resource="classpath*:spring/service/serviceSF.xml"/commerce-legacy/>
    <import resource="classpath*:spring/web/url-mapping.xml"/commerce-legacy/>

Note that these files should only contain your custom and overriding bean definitions. Do not include any out-of-the-box bean definitions.
