             Summary: struts2+spring intergration,when user aop, maybe inject 
fail
                 Key: WW-4110
                 URL: https://issues.apache.org/jira/browse/WW-4110
             Project: Struts 2
          Issue Type: Improvement
          Components: Plugin - Spring
    Affects Versions: 2.3.1.1
            Reporter: zhangkaitao


1、
    @Autowired
    private Resource resource; //no setter

<action name="myAction" class="cn.javass.MyAction">

2、use aop, for example
    <aop:config proxy-target-class="true">
        <aop:aspect ref="myAspect">
            <aop:before method="before" pointcut="execution(* 
cn.javass.MyAction.*(..))"/>
        </aop:aspect>
    </aop:config>


3、StrutsSpringObject
 bean = autoWiringFactory.autowire(clazz, 
AutowireCapableBeanFactory.AUTOWIRE_CONSTRUCTOR, false);
                bean = 
autoWiringFactory.applyBeanPostProcessorsBeforeInitialization(bean, 
bean.getClass().getName());
                // We don't need to call the init-method since one won't be 
registered.
                bean = 
autoWiringFactory.applyBeanPostProcessorsAfterInitialization(bean, 
bean.getClass().getName());  //generate proxy
return autoWireBean(bean, autoWiringFactory); //inject error  because proxy


spring`s  processing flow :

(org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory)：

1、InstantiationAwareBeanPostProcessor.applyBeanPostProcessorsBeforeInstantiation
2、InstantiationAwareBeanPostProcessor.applyBeanPostProcessorsAfterInitialization
如果此时有bean返回 直接返回；
3、doCreateBean
3.1、createBeanInstance
3.2、populateBean
3.2.1、InstantiationAwareBeanPostProcessor.postProcessAfterInstantiation
3.2.2、autowire， for example AUTOWIRE_BY_NAME，AUTOWIRE_BY_TYPE
3.2.3、InstantiationAwareBeanPostProcessor.postProcessPropertyValues
3.2.4、applyPropertyValues


4、initializeBean
4.1、invokeAwareMethods
4.2、BeanPostProcessor.postProcessBeforeInitialization
4.3、invokeInitMethods
4.4、BeanPostProcessor.postProcessAfterInitialization



5、solution

bean = autoWiringFactory.createBean(clazz, 
AutowireCapableBeanFactory.AUTOWIRE_CONSTRUCTOR, false);

bean = autoWireBean(bean, autoWiringFactory);

bean = autoWiringFactory.initializeBean(bean, bean.getClass().getName());
