[GitHub] [incubator-eventmesh] mistyzyq opened a new issue, #3248: [Bug] MQClientException: The AdminExt service state not OK, maybe started once, SHUTDOWN_ALREADY
mistyzyq opened a new issue, #3248:
URL: https://github.com/apache/incubator-eventmesh/issues/3248
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/eventmesh/issues?q=is%3Aissue) and found no similar issues.
### Environment
Windows
### EventMesh version
master
### What happened
The RocketMQAdmin#getTopic method can only be called once, all subsequent calls will get this error:
org.apache.rocketmq.client.exception.MQClientException: The AdminExt service state not OK, maybe started once, SHUTDOWN_ALREADY\nSee http://rocketmq.apache.org/docs/faq/ for further details.
I read the source code cursoryly, in RocketMQAdmin.java, in the follow code, the _adminExt_ saves it's state and can only be _start_ once, but here we _start_ and _shutdown_ every time.
```
@Override
public List<TopicProperties> getTopic() throws Exception {
try {
adminExt.start();
List<TopicProperties> result = new ArrayList<>();
Set<String> topicList = adminExt.fetchAllTopicList().getTopicList();
for (String topic : topicList) {
long messageCount = 0;
TopicStatsTable topicStats = adminExt.examineTopicStats(topic);
HashMap<MessageQueue, TopicOffset> offsetTable = topicStats.getOffsetTable();
for (TopicOffset topicOffset : offsetTable.values()) {
messageCount += topicOffset.getMaxOffset() - topicOffset.getMinOffset();
}
result.add(new TopicProperties(
topic, messageCount
));
}
result.sort(Comparator.comparing(t -> t.name));
return result;
} finally {
adminExt.shutdown();
}
}
```
### How to reproduce
1. startup eventmesh-runtime, and run dashboard
2. open dashboard page in brower, and click the Topic menu, the page url is: http://localhost:3000/topic
3. an red error toast shows: Failed to fetch the list of topics \ Unable to connect to the EventMesh daemon
