I have a bean. It have ee field
@PersistenceContext
EntityManager entityManager;
And i have a interceptor. When interceptor do aroundInvoke context's target have null entityManager
I edit org.jboss.weld.injection.FieldInjectionPoint.java
public void inject(Object declaringInstance, Object value)
{
try
{
delegate().set(declaringInstance, value);
}
catch (IllegalArgumentException e)
{
rethrowException(e);
}
catch (IllegalAccessException e)
{
rethrowException(e);
}
}
to
public void inject(Object declaringInstance, Object value)
{
try
{
Object instanceToInject = declaringInstance;
if (!isDelegate())
{
// if declaringInstance is a proxy, unwrap it
instanceToInject = InterceptionUtils.getRawInstance(declaringInstance);
}
delegate().set(instanceToInject,value);
}
catch (IllegalArgumentException e)
{
rethrowException(e);
}
catch (IllegalAccessException e)
{
rethrowException(e);
}
}
It works.
I user tomcat6.1.20 and JpaInjectionServices show below:
public class SpringJpaInjectionService implements JpaInjectionServices{
private WebApplicationContext webApplicationContext;
public SpringJpaInjectionService(ServletContext servletContext) {
webApplicationContext=WebApplicationContextUtils.getWebApplicationContext(servletContext);
}
@Override
public EntityManager resolvePersistenceContext(InjectionPoint injectionPoint) {
if (!injectionPoint.getAnnotated().isAnnotationPresent(PersistenceContext.class))
{
throw new IllegalArgumentException("No @PersistenceContext annotation found on injection point " + injectionPoint);
}
String unitname=injectionPoint.getAnnotated().getAnnotation(PersistenceContext.class).unitName();
Map<String, AbstractEntityManagerFactoryBean> emfbeans=webApplicationContext.getBeansOfType(AbstractEntityManagerFactoryBean.class, true, true);
for(Entry<String, AbstractEntityManagerFactoryBean> entry:emfbeans.entrySet())
{
AbstractEntityManagerFactoryBean absenfBean=entry.getValue();
if(unitname==null || unitname.equals(""))
return ExtendedEntityManagerCreator.createContainerManagedEntityManager(absenfBean.getNativeEntityManagerFactory());
else if(absenfBean.getPersistenceUnitName()!=null && absenfBean.getPersistenceUnitName().equals(unitname))
return ExtendedEntityManagerCreator.createContainerManagedEntityManager(absenfBean.getNativeEntityManagerFactory());
}
return null;
}
@Override
public EntityManagerFactory resolvePersistenceUnit(InjectionPoint injectionPoint) {
if (!injectionPoint.getAnnotated().isAnnotationPresent(PersistenceUnit.class))
{
throw new IllegalArgumentException("No @PersistenceContext annotation found on injection point " + injectionPoint);
}
String unitname=injectionPoint.getAnnotated().getAnnotation(PersistenceUnit.class).unitName();
Map<String, AbstractEntityManagerFactoryBean> emfbeans=webApplicationContext.getBeansOfType(AbstractEntityManagerFactoryBean.class, true, true);
for(Entry<String, AbstractEntityManagerFactoryBean> entry:emfbeans.entrySet())
{
AbstractEntityManagerFactoryBean absenfBean=entry.getValue();
if(unitname==null || unitname.equals(""))
return absenfBean.getNativeEntityManagerFactory();
else if(absenfBean.getPersistenceUnitName()!=null && absenfBean.getPersistenceUnitName().equals(unitname))
return absenfBean.getNativeEntityManagerFactory();
}
return null;
}
@Override
public void cleanup() {
// TODO Auto-generated method stub
}
}
