### Ⅲ. Describe what you expected to happen

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. cd incubator-seata-samples/at-sample/dubbo-samples-seata
2. mvn clean package -DskipTests
3. docker build account image
4. kubectl create deployment

### Ⅴ. Anything else we need to know?
Nothing

### Ⅵ. Environment:

- JDK version(e.g. `java -version`): openjdk 11
- Seata client/server version: 2.0.0
- Database version: MYSQL Server 8.0
- OS(e.g. `uname -a`): MacOS M2 Version 14.4.1
- Docker Version: 24.0.6

Start in incubator-seata-samples/at-sample/dubbo-samples-seata and inspect the account application's database setup, with OrderApplication.java:29 as the reported entry point. Reproduce with the listed Maven, Docker, and kubectl steps; done means the account application starts without the SQLNonTransientConnectionException when connecting to MySQL.
