Spring请求范围bean代理bean无法注入

Question

我有一个这样的代理请求范围bean：

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

我想将其注入服务类中：

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

当我启动我的应用程序和/或集成测试时，它就不会启动。 应用程序如下所示：

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

我得到的错误：

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?

我检查了什么：

• 注释处理已启用，否则AnyService将完全不实例化
• AnyBean不是最终的
• 请求范围与AspectJ代理（ScopedProxyMode.TARGET_CLASS）一起在AnyBean中定义。
• 存在EnableAspectJAutoProxy批注

• 以下罐子位于类路径中：

  D：\\ Users \\ liptak.m2 \\ repository \\ org \\ aspectj \\ aspectjweaver \\ xxx \\ aspectjweaver-xxx.jar D：\\ Users \\ liptak.m2 \\ repository \\ org \\ aspectj \\ aspectjrt \\ xxx \\ aspectjrt-xxx.jar D： \\ Users \\ liptak.m2 \\存储库\\ cglib \\ cglib \\ xxx \\ cglib-xxx.jar D：\\ Users \\ liptak.m2 \\ repository \\ org \\ ow2 \\ asm \\ asm \\ xxx \\ asm-xxx.jar D：\\ Users \\ liptak.m2 \\ repository \\ org \\ springframework \\ spring-aop \\ xxx.RELEASE \\ spring-aop-xxx.RELEASE.jar D：\\ Users \\ liptak.m2 \\ repository \\ aopalliance \\ aopalliance \\ xxx \\ aopalliance-xxx.jar D：\\ Users \\ liptak.m2 \\ repository \\ org \\ springframework \\ spring-aspects \\ xxx.RELEASE \\ spring-aspects-xxx.RELEASE.jar

看来，一切都应该很好。 仍然不起作用。 您有什么想法要检查吗？ 您将调试哪个Spring类？

更新：

Web XML还包含RequestContextListener：

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

更新2：

当我向org.springframework.aop.config.ScopedProxyBeanDefinitionDecorator.decorate（Node，BeanDefinitionHolder，ParserContext）添加一个断点时，根本不会触发它。

解决的办法是我的春季背景有点混乱。 没有基于注释处理实例化AnyBean。 我已经在XML配置中找到了它，在其中直接像这样创建它：

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

一旦我像这样更改它，它就会起作用：

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

当注释和基于xml的配置混合在一起时，我很喜欢 :)
