> CXF JAX-WS: @PostConstruct methods invoked twice in Spring-based projects
> -------------------------------------------------------------------------
>
> Key: CXF-3959
> URL: https://issues.apache.org/jira/browse/CXF-3959
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 2.4.2, 2.5
> Reporter: Rolf Schäuble
> Attachments: cxf-postconstruct-bug.zip
>
>
> Under the following circumstances, @PostConstruct methods on classes exported
> as JAX-WS WebService are invoked twice:
> - The application uses Spring as IoC container
> - Spring's support for JSR 250 annotations is active (using the
> CommonAnnotationBeanPostProcessor bean or <context:annotation-config/>
> - The exported bean is declared as Spring bean in the application context
> - The <jaxws:endpoint> declaration refers to the declared bean
> (<jaxws:endpoint implementor="#beanName"/>
> The last point is important:
> - <jaxws:endpoint implementor="the.bean.class.name"/> *does not* not show the
> wrong behavior
> - <bean id="theBean" class="the.bean.class.name"/>
> <jaxws:endpoint implementor="#theBean'"/> *does* show the wrong behaviur
>
> I have built an example application (based on CXF's java_first_spring_support
> sample) that shows the problem. It contains two classes:
> 1. PostConstructCalledOnce: this class is exported using the <jaxws:endpoint
> implementor="the.bean.class.name"/> synxtax
> 2. PostConstructCalledTwice.java: this class is exported using the
> <jaxws:endpoint implementor="#theBean'"/>
> Both classes contain a postConstruct method; both method print the class's
> name to the console. When the application is started ("mvn -Pserver"), it can
> be observed that PostConstructCalledOnce#postConstruct is called once and
> PostConstructCalledTwice#postConstruct is called twice.
> Desired behavior: both postConstruct methods should only be invoked once.
> Workaround:
> 1. Annotate the affected classes with CXF's @NoJSR250Annotations annotation
> 2. Use the <jaxws:endpoint implementor="the.bean.class.name"/> syntax.
> Problem: This way, Spring is not able to wrap the bean with a proxy (e.g. for
> transaction support)
