Java 无法从spring父（共享）上下文自动连接bean

我有一个简单的，有两个春天背景的战争。 My web.xml包含：

<context-param>
    <param-name>parentContextKey</param-name>
    <param-value>ejbContext</param-value>
</context-param>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml
    </param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context:annotation-config />
<context:component-scan base-package="ru.fns"/>

此外，将springBean注入到parentSpringBean中也可以，但是如何呢

parentSpringBean代码示例：

 // there's neither @Component nor @Service annotation
public class ParentSpringBean {
private static transient final Logger log = LoggerFactory.getLogger(ParentSpringBean.class);

private String stringProperty;

@EJB(mappedName = "EEBean")
private EEBean eeBean; // ok



@Autowired
private SpringBean springBean; // child context bean, works but why?

我已经在WebSphere上测试了几天，但仍然无法理解这种奇怪的行为。有人知道为什么会这样吗？先谢谢你

<context:annotation-config />
<context:component-scan base-package="ru.fns"/>

@Component()
@Qualifier("springBean")
public class SpringBean {
private static transient final Logger log = LoggerFactory.getLogger(SpringBean.class);

@Value("${logs.level}")
private String stringProperty;

@EJB(mappedName = "EEBean")
private EEBean eeBean;


@Autowired
@Qualifier("parentSpringBean")
private ParentSpringBean parentSpringBean; // it fails

 // there's neither @Component nor @Service annotation
public class ParentSpringBean {
private static transient final Logger log = LoggerFactory.getLogger(ParentSpringBean.class);

private String stringProperty;

@EJB(mappedName = "EEBean")
private EEBean eeBean; // ok



@Autowired
private SpringBean springBean; // child context bean, works but why?
