### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version 3.2.14 ### Steps to reproduce this issue How to get attachment data in the consumer ,attachment data set from provider cusome exception filter ? DubboProviderExceptionFilter: RpcContextAttachment serverContext = RpcContext.getServerContext(); serverContext.setObjectAttachment(ATTA_NAME_EXCEPTION_CODE, br.getCode()); DubboConsumerExceptionFilter: RpcContext.getServerContext().getObjectAttachments() ,RpcContext.getContext().getAttachments(); Neither method can be obtained ### What you expected to happen DubboProviderExceptionFilter set attachment data , DubboConsumerExceptionFilter get server attachment data ,used to customize exceptions extra data ### Anything else source code: ``` @Activate(group = CommonConstants.PROVIDER ) public class DubboProviderExceptionFilter implements Filter, Filter.Listener { protected final Logger logger = LoggerFactory.getLogger(this.getClass()); public static String ATTA_NAME_EXCEPTION_CODE = "__code"; public static String ATTA_NAME_EXCEPTION_DETAIL_MSG = "__detailMsg"; public static String ATTA_NAME_EXCEPTION_DETAIL_DATA = "__data"; @Override public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException { return invoker.invoke(invocation); } @Override public void onResponse(Result appResponse, Invoker<?> invoker, Invocation invocation) { if (appResponse.hasException() && GenericService.class != invoker.getInterface()) { try { Throwable exception = appResponse.getException(); String className = exception.getClass().getName(); //如果是我们系统自定义异常直接返回 if ( ClassUtil2.isAssignable(ServiceException.class, exception.getClass())) { //服务提供方写入回传参数 ServiceException br = (ServiceException) exception; invocation.setObjectAttachment(ATTA_NAME_EXCEPTION_CODE, br.getCode()); invocation.setObjectAttachment(ATTA_NAME_EXCEPTION_DETAIL_MSG, br.getDetailMsg()); invocation.setObjectAttachment(ATTA_NAME_EXCEPTION_DETAIL_DATA, br.getExtraData()); RpcContextAttachment serverContext = RpcContext.getServerContext(); serverContext.setObjectAttachment(ATTA_NAME_EXCEPTION_CODE, br.getCode()); serverContext.setObjectAttachment(ATTA_NAME_EXCEPTION_DETAIL_MSG, br.getDetailMsg()); serverContext.setObjectAttachment(ATTA_NAME_EXCEPTION_DETAIL_DATA, br.getExtraData()); return; } ``` ``` @Activate(group = CommonConstants.CONSUMER ) public class DubboConsumerExceptionFilter implements Filter, Filter.Listener { @Override public void onResponse(Result appResponse, Invoker<?> invoker, Invocation invocation) { Throwable exec = appResponse.getException(); if (exec != null && ServiceException.class.isAssignableFrom(exec.getClass())) { Map<String, String> attachments = invocation.getAttachments(); if (attachments.containsKey(ATTA_NAME_EXCEPTION_CODE)) { ReflectionUtil.setFieldValue(exec, "code", attachments.get(ATTA_NAME_EXCEPTION_CODE)); } if (attachments.containsKey(ATTA_NAME_EXCEPTION_DETAIL_MSG)) { ReflectionUtil.setFieldValue(exec, "detailMsg", attachments.get(ATTA_NAME_EXCEPTION_DETAIL_MSG)); } if (attachments.containsKey(ATTA_NAME_EXCEPTION_DETAIL_DATA)) { ReflectionUtil.setFieldValue(exec, "extraData", attachments.get(ATTA_NAME_EXCEPTION_DETAIL_DATA)); } } } ``` ### Are you willing to submit a pull request to fix on your own? - [X] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
