Ignoring spring bean injection if class not avaliable

We have set of common spring application context configuration files. Depending on the deployment (We deploy one module or multiple module), bean injection classes will change e.g.

<bean id="tagService" class="com.ekaplus.service.tag.TagService" >

     <property name="mdmTagService" ref="mdmTagService" />

      <property name="physicalTagService" ref="physicalTagService" />
  </bean>

physcialTagService bean will be available if physical module is deployed else it won't be available. I don't want to change the common configuration for each deployment. Is there any way in spring to ignore certain beans injection if class is not available.

You could also use a parent-child implementation by using "abstract", ie

<bean id="tagServiceParent" class="com.ekaplus.service.tag.TagService" abstract="true">
<property name="implementedTagService" ref="defaultTagService" />
..other common properties here...
</bean>

<bean id="tagService" parent="tagServiceParent">
<property name="implementedTagService" ref="mdmTagService" />
</bean>

But im not sure how you're implementing, so it might not suit your needs.

Well if you just use autowiring by name or by type, Spring won't autowire anything it can't find:

<bean class="foo.bar.Phleem" autowire="byType" />
