             Summary: Allow conduit match pattern to be customized by PropertyPlaceholderConfigurer
                 Key: CXF-4811
                 URL: https://issues.apache.org/jira/browse/CXF-4811
             Project: CXF
          Issue Type: New Feature
          Components: Integration
    Affects Versions: 2.4.3
            Reporter: Ivan Latysh
            Priority: Critical


Use-case:
  Developed jaxrs client has no knowledge of the server URL until it is shipped to a customer.
  To address the issue, server name and port has been externalized and handled by a standard {{PropertyPlaceholderConfigurer}}:
{code}
<jaxrs:client id="serviceClient"
address="http://${server.name}:${server.port}/services/*"/>

<context:property-placeholder/>

<bean class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer">
		<property name="order" value="1"/>
		<property name="ignoreUnresolvablePlaceholders" value="false"/>
</bean>
{code}

But currently http conduit can not be configured as match pattern is set the conduit name, rather than a property.
{code}
<cxf-http:conduit name="http://localhost/services.*" />
{code}

The best option is to introduce custom URL Matchers, so conduit delegate actual URL matching to a configurable implementation.

Than a simple solution would be to extend org.apache.cxf.configuration.spring.ConfigurerImpl and resolve the property placeholders before compiling the pattern in {{initWildcardDefinitionMap}} method. But the poor architectural decisions led to {{PropertyResourceConfigurer}} to be non-reusable. It supports rigid visitor pattern, and do not even provide a method to resolve a property placeholder after {{postProcessBeanFactory}} has been called.

So the dirty hack would be to configure pattern in the conduit property, rather in the name.
{code}
<cxf-http:conduit id="service1Conduit">
  <property name="url" value="http://${server.name}:${server.port}/services/*">
</cxf-http:conduit>
{code}
