我正在使用自定义FactoryBean来构建一组单例对象。从FactoryBean我以编程方式调用'autowireBeanProperties'将依赖项注入bean。
context.getAutowireCapableBeanFactory().autowireBeanProperties(o, AutowireCapableBeanFactory.AUTOWIRE_BY_NAME, false);
(我知道这不是一个最佳方案,但我有理由以这种方式设计东西,我打算改变,但我认为需要更多时间)
其中一个依赖项是自定义范围的bean,我们将其称为“userSession”范围。
我收到以下错误:
Property 'scopedBean' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.connector': Scope 'userSession' 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: Unknown identity: null
我尝试了两个和一个自定义的ScopedProxy(仅在方法调用时实例化内部userSession-scoped对象),但结果是相同的。 堆栈看起来像这样:
UserSessionScope.get(String, ObjectFactory) line: 23

DefaultListableBeanFactory(AbstractAutowireCapableBeanFactory).autowireBeanProperties(Object, int, boolean) line: 379
MyFactoryBean.processInjection(Object) line: 68
我无法想象为什么在实例化阶段调用了调用... 我没有逻辑可以做到这一点......
另一件事是:我没有名为'scopedTarget.connector'的bean。
感谢您提供任何线索
(顺便说一句:我使用的是Spring 3.2版本)
答案 0 :(得分:0)
好的,这是我的错。我想知道为什么我会得到那种不相关的堆栈跟踪...
问题出在其他地方......
