EJB 3.0 with Spring 1.2 SpringBeanAutowiringInterceptor

ejb3 Spring

The EJB
EJB3-compliant interceptor class that injects Spring beans into fields

and methods which are annotated with @Autowired. Performs injection after
construction as well as after activation of a passivated bean.
To be applied through an @Interceptors annotation in the

EJB Session Bean
or Message-Driven Bean class, or through an interceptor-binding XML
element in the EJB deployment descriptor.
Delegates to Spring's AutowiredAnnotationBeanPostProcessor underneath,
allowing for customization of its specific settings through overriding
the configureBeanPostProcessor(org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor,
java.lang.Object) template method.
The actual BeanFactory to obtain Spring beans from is determined by the getBeanFactory(java.lang.Object)
template method. The default implementation obtains the Spring ContextSingletonBeanFactoryLocator,
initialized from the default resource location classpath*:beanRefContext.xml,
and obtains the single ApplicationContext defined there
