**rocketMq version**: rocketmq-all-5.1.3-bin-release **client version** : rocketmq-client-java 5.0.5 ### producer code : public static void main(String[] args) throws ClientException { // 接入点地址,需要设置成Proxy的地址和端口列表,一般是xxx:8081;xxx:8081。 String endpoint = "localhost:8081"; // 消息发送的目标Topic名称,需要提前创建。 String topic = "orderTopic4"; ClientServiceProvider provider = ClientServiceProvider.loadService(); ClientConfigurationBuilder builder = ClientConfiguration.newBuilder().setEndpoints(endpoint); ClientConfiguration configuration = builder.build(); // 初始化Producer时需要设置通信配置以及预绑定的Topic。 Producer producer = provider.newProducerBuilder() .setTopics(topic) .setClientConfiguration(configuration) .build(); // Define your message body. byte[] body = "This is a FIFO message for Apache RocketMQ".getBytes(StandardCharsets.UTF_8); String tag = "yourMessageTagA"; final Message message = provider.newMessageBuilder() // Set topic for the current message. .setTopic(topic) // Message secondary classifier of message besides topic. .setTag(tag) // Key(s) of the message, another way to mark message besides message id. .setKeys("yourMessageKey-1ff69ada8e0e") // Message group decides the message delivery order. .setMessageGroup("yourMessageGroup0") .setBody(body) .build(); try { final SendReceipt sendReceipt = producer.send(message); log.info("Send message successfully, messageId={}", sendReceipt.getMessageId()); } catch (Throwable t) { log.error("Failed to send message", t); } // Close the producer when you don't need it anymore. // You could close it manually or add this into the JVM shutdown hook. // producer.shutdown(); } **question:** the topic "orderTopic4" not exist,it report a bug with `DESC: No topic route info in name server for the topic: orderTopic4` I think i open `the autoCreateTopicEnable=true` but it doesn't create the topic ,it doesn't work GitHub link: https://github.com/apache/rocketmq/discussions/7378 ---- This is an automatically sent email for dev@rocketmq.apache.org.
