弹簧请求范围 bean 代理 bean 不能注入

Question

我有一个代理的请求范围 bean，如下所示：

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

我想把它注入到服务类中：

@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：

• 启用注释处理，否则 AnyService 根本不会实例化
• AnyBean不是最终的
• 请求范围与AspectJ代理(ScopedProxyMode.TARGET_CLASS)一起在AnyBean中定义
• 存在启用方面JAuto代理注释

• 以下 jar 位于类路径上：

  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\repository\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.释放.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.释放

  .jar

所以看起来，一切都应该没事。它仍然不起作用。你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：

当我将断点添加到org.springframework.aop.config.ScopedProxyBeanDefinitionDecorator.decorate(Node，BeanDefinitionHolder，ParserContext)时，它根本不会被触发。

解决方案是我的春季上下文有点混乱。AnyBean 不是基于注释处理实例化的。我在XML配置中找到了它，它是直接像这样创建的：

<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>

我喜欢将注释和基于 xml 的配置混为一谈:)
