Subject [jira] [Updated] (WW-4110) struts2+spring intergration,when user aop, maybe inject fail
Date Mon, 28 Jul 2014 15:39:40 GMT

     [ https://issues.apache.org/jira/browse/WW-4110?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lukasz Lenart updated WW-4110:
------------------------------

    Description: 
1.
{code:java}
    @Autowired
    private Resource resource; //no setter
{code}

{code:xml}
<action name="myAction" class="cn.javass.MyAction">
{code}

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

3. StrutsSpringObject
{code:java}
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
{code}

spring`s  processing flow :

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

# InstantiationAwareBeanPostProcessor.applyBeanPostProcessorsBeforeInstantiation
# InstantiationAwareBeanPostProcessor.applyBeanPostProcessorsAfterInitialization
# doCreateBean
## createBeanInstance
## populateBean
### InstantiationAwareBeanPostProcessor.postProcessAfterInstantiation
### autowire, for example AUTOWIRE_BY_NAME,AUTOWIRE_BY_TYPE
### InstantiationAwareBeanPostProcessor.postProcessPropertyValues
### applyPropertyValues
# initializeBean
## invokeAwareMethods
## BeanPostProcessor.postProcessBeforeInitialization
## invokeInitMethods
## BeanPostProcessor.postProcessAfterInitialization
# solution
{code:java}
bean = autoWiringFactory.createBean(clazz, AutowireCapableBeanFactory.AUTOWIRE_CONSTRUCTOR,
false);
bean = autoWireBean(bean, autoWiringFactory);
bean = autoWiringFactory.initializeBean(bean, bean.getClass().getName());
{code}


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


  was:
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());




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
