Description

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
3. doCreateBean
   1. createBeanInstance
   2. populateBean
      1. InstantiationAwareBeanPostProcessor.postProcessAfterInstantiation
      2. autowire， for example AUTOWIRE_BY_NAME，AUTOWIRE_BY_TYPE
      3. InstantiationAwareBeanPostProcessor.postProcessPropertyValues
      4. applyPropertyValues
4. initializeBean
   1. invokeAwareMethods
   2. BeanPostProcessor.postProcessBeforeInitialization
   3. invokeInitMethods
   4. BeanPostProcessor.postProcessAfterInitialization
5. solution

   bean = autoWiringFactory.createBean(clazz, AutowireCapableBeanFactory.AUTOWIRE_CONSTRUCTOR, false);
   bean = autoWireBean(bean, autoWiringFactory);
   bean = autoWiringFactory.initializeBean(bean, bean.getClass().getName());
   

please delete src/main/java patch
com.opensymphony.xwork2.spring.SpringObjectFactory
test, will see resource is null；
but use this patch will be not null
