kiritokun07 opened a new issue #395:
URL: https://github.com/apache/rocketmq-spring/issues/395
1.环境
```
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.2</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>rocketmq-spring-boot-starter</artifactId>
<version>2.2.1</version>
</dependency>
```
2.我做了什么
简单实现了RocketMQLocalTransactionListener接口的两个方法，都是返回`RocketMQLocalTransactionState.COMMIT`
```
@Service
@RocketMQTransactionListener
public class OrderServiceImpl4Listener implements
RocketMQLocalTransactionListener {
}
```
在Controller中发送了一个事务消息
```
@Resource
private RocketMQTemplate rocketMQTemplate;
@RequestMapping("/test2")
public void test2() {
Message<String> message = MessageBuilder.withPayload("发送了一个事务消息")
.setHeader(RocketMQHeaders.TRANSACTION_ID,"KEY_").build();
rocketMQTemplate.sendMessageInTransaction(topic, message, null);
}
```
3.报错
>java.lang.IllegalStateException: The rocketMQTemplate does not exist
TransactionListener at
org.apache.rocketmq.spring.core.RocketMQTemplate.sendMessageInTransaction(RocketMQTemplate.java:1014)
~[rocketmq-spring-boot-2.2.1.jar:2.2.1]
进入`sendMessageInTransaction`方法后，因为`transactionListener`不存在抛出异常了
这篇文章说：In sendMessageInTransaction(), the first parameter transaction name
("test") must be same with the @RocketMQTransactionListener's member field
'transName'
但是由于版本的问题，我没有办法设置transName
[事务消息](https://github.com/apache/rocketmq-spring/wiki/%E4%BA%8B%E5%8A%A1%E6%B6%88%E6%81%AF)
我也曾试图使用一个新的Template，然后在Controller中注入新的template，但是仍然报错
```
@ExtRocketMQTemplateConfiguration
public class ExtRocketMQTemplate extends RocketMQTemplate {
}
```
