Restart CamelContext won't restart services on CxfBeanEndpoint
--------------------------------------------------------------
Key: CAMEL-2991
URL: https://issues.apache.org/activemq/browse/CAMEL-2991
Project: Apache Camel
Issue Type: Bug
Components: camel-core, camel-cxf
Reporter: William Tam
Fix For: 2.5.0
A route that sends to a CxfBean destination is unusable after the CamelContext
has been stopped and re-started. The following is an example of a route that
demonstrates the problem.
{code}
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";>
<route>
<from
uri="jetty:http://localhost:9000?matchOnUriPrefix=true"; />
<to uri="cxfbean:customerServiceBean" />
</route>
</camelContext>
<util:list id="customerServiceBean">
<bean
class="org.apache.camel.component.cxf.jaxrs.testbean.CustomerService" />
</util:list>
{code}
The follow issues have been identified.
1) SendProcessor should implement the Navigate interface so that its children
(if they are Services) can be managed by the lifecycle methods. This will
address any destination endpoint that requires services to be re-started.
2) CxfBeanEndpoint should be a Service itself. The reason why the start() on
CxfBeanEndpoint gets called during the first start is because
CxfBeanComponent.start() gets invoked during route definition initialization.
The problem is that re-starting doesn't trigger the CxfBeanComponent.start()
method. Therefore, putting the hook in CxfBeanComponent to start/stop
CxfBeanEndpoint was a bug.
3) The default type converter which is a Service won't get "re-started' as the
(lazy-instantiation) getTypeConverter() method won't perform addService() on a
created but "stopped' typeConverter. We need to discuss the correct remedy
since I am not sure how to fix it. It is kind of strange that the type
converter is a service (which has the start/stop semantics) and yet it can be
used even the CamelContext is stopped (or never started). In the patch, I just
set the type converter to null in DefaultCamelContext doStop() for now.
