BeanInCreationException when CXF client factorybean used
--------------------------------------------------------
Key: CXF-3805
URL: https://issues.apache.org/jira/browse/CXF-3805
Project: CXF
Issue Type: Bug
Components: JAX-WS Runtime
Affects Versions: 2.4.2
Reporter: Tomasz Bech
Priority: Critical
Attachments: beanincreationexction.zip
In complex spring context, when JaxWsProxyFactoryBean is used, context fails to
start with BeanCurrentlyInCreationException.
Part of exception:

The main reason of the problem is that JaxWsProxyFactoryBean calls spring
getBeanNamesForType, which
needs to instantiate all spring beans - and it is very easy to reach the case,
that in spring context
in creation there are beans not fully initialized yet - and when
getBeanNamesForType is called - BIG BUM - exception.
It is not proper pattern to use spring getBeanNamesForType from
FactoryBean.create method.
I've tracked the problem and isolated simple test case - it is attached.
Unpack it into
apache-cxf-2.4.2-src\apache-cxf-2.4.2-src\systests\jaxws\src\test\java
and run:
mvn -Dtest=BeanInCreationExceptionTest test
It fails for spring2 and spring3 as well.
When you look at beans.xml, you will see that there are no circular
dependencies which usually cause
BeanCurrentlyInCreationException - but JaxWsProxyFactoryBean.create is making
the problem.
Just comment one line as below in beans.xml:
<bean id="testBeanBBOImpl"
class="org.apache.cxf.systest.beanincreationexception.TestBeanABOImpl">
<property name="bean" ref="testBeanABO"/>
<!-- <property name="client" ref="client2"/> -->
</bean>
and test runs ok.
How to fix? Provide lighter version (or a switch) of JaxWsProxyFactoryBean - it
can just create the proxy,
and the rest (endpoint, client, all the stuff which requires
getBeanNamesForType) can be instantiated later - for example in
AfterpropertiesSet phase.
Or avoid getBeanNamesForType if possible.
Now the workaround we try, is to change the order of spring beans xml's and
have a luck. Eventually changing from injecting client service/portType to
getting them from applicationcontext.getBean - but it is not good practice.
