java.lang.Objectorg.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor
public class SpringBeanAutowiringInterceptor
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.
NOTE: If you have more than one shared ApplicationContext definition available
in your EJB class loader, you need to override the getBeanFactoryLocatorKey(java.lang.Object)
method and provide a specific locator key for each autowired EJB.
Alternatively, override the getBeanFactory(java.lang.Object) template method and
obtain the target factory explicitly.
WARNING: Do not define the same bean as Spring-managed bean and as
EJB3 session bean in the same deployment unit. In particular, be
careful when using the <context:component-scan> feature
in combination with the deployment of Spring-based EJB3 session beans:
Make sure that the EJB3 session beans are not autodetected as
Spring-managed beans as well, using appropriate package restrictions.
