dkisser opened a new issue #8793: URL: https://github.com/apache/dubbo/issues/8793
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. - [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.0.1、3.0.2 * Operating System version: Mac OS * Java version: 1.8 ### Steps to reproduce this issue 1. 编写一个Filter和一个普通SpringBean 2. 装载Filter 3. 启动dubbo-demo-annotation-consumer(dubbo内置示例工程) Filter和SpringBean代码如下。 @Activate(group = {"consumer", "provider"}) public class DemoFilter implements Filter { private DemoServiceComponent demoServiceComponent; private ABTestBean abTestBean; public void setDemoServiceComponent(DemoServiceComponent demoServiceComponent) { this.demoServiceComponent = demoServiceComponent; } public void setAbTestBean(ABTestBean abTestBean) { this.abTestBean = abTestBean; } @Override public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException { System.out.println("1"); return invoker.invoke(invocation); } } @Service("abTestBean") public class ABTestBean { private String name = "1f2"; } 启动后发现DemoFilter中的SpringBean无法注入。经分析，IOC启动是就会通过DubboInfraBeanRegisterPostProcessor##setApplicationContex将上下文设置进SprinExtensionFactory#CONTEXTS属性中。  但是，在随后SpringExtensionFactory的初始化过程中又会调用SpringExtension#initialize，此处会清空当前的上下文  由于此处启动的是消费端，后面没有再次设置上下文进SpringExtensionFactory的地方，因此会导致Filter中相关的SpringBean注入不进去，结果如下所示。  Pls. provide [GitHub address] to reproduce this issue. ### Expected Result 期望后续能有一个好的解决方案，目前提供两个止血方案。 1. 使用SpringContext自行获取，参考如下：https://blog.csdn.net/sinat_21184471/article/details/81353431 2. 在DubboBootstrapApplicationListener#onContextRefreshedEvent中将上下文加入到SpringExtensionFactory(这只是暂时止血的方案，是否”优雅“有待讨论)  What do you expected from the above steps？ ### Actual Result What actually happens?
