Spring C-notation

In a previous post, I talked about Spring P-notation.  In this blog post, I will give an example of the Spring C-notation for constructor arguments.

The C-notation namespace needs to be added to your configuration file.

xmlns:c="http://www.springframework.org/schema/c"

All that is left is to use it for a constructor argument

    <!-- removed unnecessary configurations -->

    <bean id="requestFactory" class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory"
          p:readTimeout="250"
          p:connectTimeout="250"/>

    <bean id="restTemplate" class="org.springframework.web.client.RestTemplate"
          c:requestFactory-ref="requestFactory"/>
</beans>
