Spring请求范围bean代理bean无法注入

Question

@Component
@Scope(value="request", proxyMode = ScopedProxyMode.TARGET_CLASS)
@Lazy
public class AnyBean {
...
}

@Service
@Transactional
public class AnyService {
    @Autowired
    private AnyBean anyBean;
}

@Configuration
@EnableCommonsPersistenceAutoConfguration
@ImportResource({
   ....
})
@EnableAspectJAutoProxy
public class ApplicationTest {
...
}

我得到的错误是：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'anyBean': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

我检查的内容：

>

已启用批注处理，否则AnyService根本不会实例化

AnyBean不是最终的

请求作用域在AnyBean中与AspectJ代理(ScopedProxyMode.target_class)

一起定义

存在EnableAspectJAutoproxy批注

类路径上有以下JAR：

Web XML还包含RequestContextListener：

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

当我向org.springframework.aop.config.ScopedProxyBeanDefinitionDecorator.Decorate（节点,BeanDefinitionHolder,ParserContext）添加断点时，它根本不会被触发。

解决方案是我的spring上下文有点混乱。AnyBean不是基于注释处理实例化的。我在一个XML配置中找到了它，在这里直接创建它，如下所示：

<bean id="anyBean" class="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.AnyBean"  scope="request" lazy-init="true"/>

我这样一改，就管用了：

<bean id="anyBean" class="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.AnyBean"  scope="request" lazy-init="true">
    <aop:scoped-proxy proxy-target-class="true"/>
</bean>

我喜欢将注释和基于xml的配置混在一起：）
