**Issue Evaluation**
Category: `question` | Status: **Answered**
Yes, rocketmq-spring-boot-starter 2.3.3 supports ordered (sequential)
messages.
**Usage:**
Add `selectorExpression = "*"` and set the message key to your ordering key
(e.g., order ID). Use `@RocketMQMessageListener` with the `selectorExpression`
attribute, and send messages with the same hash key:
```java
// Producer: send with ordering key
rocketMQTemplate.syncSendOrderly("topic-name", message, "order-id-123");
```
Messages with the same `hashKey` will be sent to the same queue and consumed
in order.
