Getting Spring #Autowired and #postconstuct work - spring

Question

I am trying to introduce a new bean to existing project
Current bean is
package w.x.y.z.pkgA
#Component
public class BeanA implements InterfaceA {
}
And I am trying to add new Bean to w.x.y.z.pkgB
package w.x.y.z.pkgB
public class BeanB implements InterfaceB {
#Autowired
private BeanA beanA
#PostConstruct
public void postConstructMethod() {
//Call some method in BeanA
}
}
From BeanB I want to access BeanA data and in BeanB post construct I want to register BeanB with BeanA. So I want to call BeanA method
And All these packages are packaged as jar
and spring context xml is
<context:annotation-config />
<context:component-scan base-package="w.x.y.z.pkgA,w.x.y.z.pkgB" />
<bean id="beanb" clas="w.x.y.z.pkgB.BeanB"></bean>
But during deployment I get exception about bean in create state
Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'context': Requested bean is currently in creation: Is there an unresolvable circular reference?

I have also tried removed #Autowired and getting the BeanA object using getBeanFactory().getBean(BeanA.class). But I get same error.
If I remove bean entry from xml file them it gets deployed properly but post construct is never called as it is no longer a bean.
BeanA is not dependent on BeanB at all. No references?
Is there a way to get this #Autowired and #PostConstruct to work when 2 beans are in same jar?

Answer 1

You declare the bean as <bean id="beanb" clas="w.x.y.z.BeanB"> from w.x.y.z package.
Try with
package w.x.y.z
#Component
public class BeanA implements InterfaceA {
}
package w.x.y.z
public class BeanB implements InterfaceB {
private BeanA beanA
#PostConstruct
public void postConstructMethod() {
//Call some method in BeanA
}
// Getters and Setters
}
and
<context:annotation-config />
<context:component-scan base-package="w.x.y.z" />
<bean id="beanb" clas="w.x.y.z.BeanB">
<property name="beanA" value="beanA"/> <!-- Spring will create beanA as it is annotated with #Component -->
</bean>
