[GitHub] [shardingsphere] ICannerxy opened a new issue, #26658: Connection occasionally closed when using the jdbc parameter `useServerPrepStmts=true`
ICannerxy opened a new issue, #26658:

## Bug Report
Before report a bug, make sure you have:
- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more details.
If no response anymore and we cannot reproduce it on current information, we will **close it**.
Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
5.1.2
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavio
Connection is always available, not closed.
### Actual behavior
In the case of continuous calls, the connection will be closed after about a few minutes.
### Reason analyze (If you can)
- before jdbcUrl: `useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&allowMultiQueries=true`
- after jdbUrl: `useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useServerPrepStmts=true`
When we use before jdbcUrl, Connection is ok, not closed.
But we need to use the jdbc batch update function, so we have added the parameter `useServerPrepStmts=true` to support the batch function, and also removed the `allowMultiQueries=true` parameter. when we use after jdbUrl, the connection will be closed after about a few minutes.
The error is as follows:

### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
