【背景】业务应用中会自定义`Filter`，里面会使用`RpcContext.getServiceContext().isConsumerSide()`。 `dubbo-3.2.10`还有出现这个异常，原因是`RpcContext.getServiceContext().getUrl()`返回是null，所以调用`RpcContext.getServiceContext().isConsumerSide()`报NPE。 根因是`context=ContextFilter`没有最先执行，`dubbo-3.2.10.jar`好像不会自动加载这些`Filter`。 <img width="892" alt="image" src="https://github.com/apache/dubbo/assets/1811851/13e2d80b-64ff-463b-b274-26ac9b9f819d";> <img width="1023" alt="image" src="https://github.com/apache/dubbo/assets/1811851/fa6ef112-3a8e-41f1-b437-6d4403621580";> ```java @Activate(group = {CommonConstants.PROVIDER, CommonConstants.CONSUMER}, order = -1) public class DubboAccessLogFilter implements Filter { @Trace public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException { RpcContext rpcContext = RpcContext.getServiceContext(); try { // ... if (rpcContext.isProviderSide()) { // ... } else { // ... } } catch (Throwable e) { // ... } Result result = invoker.invoke(invocation); return result; } } ``` -- This is an automated message from the Apache Git Service.
