说在前面

client管理检查client配置

源码解析

进入到这个方法，org.apache.rocketmq.broker.processor.ClientManageProcessor.checkClientConfig(ChannelHandlerContext, RemotingCommand)

public RemotingCommand checkClientConfig(ChannelHandlerContext ctx, RemotingCommand request)        throws RemotingCommandException {        final RemotingCommand response = RemotingCommand.createResponseCommand(null);
        CheckClientRequestBody requestBody = CheckClientRequestBody.decode(request.getBody(),            CheckClientRequestBody.class);
        if (requestBody != null && requestBody.getSubscriptionData() != null) {            SubscriptionData subscriptionData = requestBody.getSubscriptionData();
            if (ExpressionType.isTagType(subscriptionData.getExpressionType())) {                response.setCode(ResponseCode.SUCCESS);                response.setRemark(null);                return response;            }
            if (!this.brokerController.getBrokerConfig().isEnablePropertyFilter()) {                response.setCode(ResponseCode.SYSTEM_ERROR);                response.setRemark("The broker does not support consumer to filter message by " + subscriptionData.getExpressionType());                return response;            }
            try {                FilterFactory.INSTANCE.get(subscriptionData.getExpressionType()).compile(subscriptionData.getSubString());            } catch (Exception e) {                log.warn("Client {}@{} filter message, but failed to compile expression! sub={}, error={}",                    requestBody.getClientId(), requestBody.getGroup(), requestBody.getSubscriptionData(), e.getMessage());                response.setCode(ResponseCode.SUBSCRIPTION_PARSE_FAILED);                response.setRemark(e.getMessage());                return response;            }        }
        response.setCode(ResponseCode.SUCCESS);        response.setRemark(null);        return response;    }

返回到这个方法，org.apache.rocketmq.broker.processor.ClientManageProcessor.checkClientConfig(ChannelHandlerContext, RemotingCommand)结束。
