- 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?
build.gradle:
`compile group: 'org.apache.shardingsphere', name: 'shardingsphere-jdbc-core-spring-boot-starter', version: "5.0.0-alpha"`
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
In one transaction, I'm trying to execute two same logic sqls with different hint. I think that it will execute two actual sql in different sharding table .
```
@Transactional
public Object hello(){
try (HintManager hintManager=HintManager.getInstance();){
// 指定查询的分表
hintManager.addTableShardingValue("t_order_hint","40");
TOrderExtend tOrder=tOrderExtendMapper.selectOne(Wrappers.<TOrderExtend>lambdaQuery().eq(TOrderExtend::getUserId,9));
LOGGER.info(tOrder.toString());
}
try (HintManager hintManager=HintManager.getInstance();){
// 指定查询的分表
hintManager.addTableShardingValue("t_order_hint","39");
TOrderExtend tOrder=tOrderExtendMapper.selectOne(Wrappers.<TOrderExtend>lambdaQuery().eq(TOrderExtend::getUserId,9));
LOGGER.info(tOrder.toString());
}
Map<String,String> result=new HashMap<>();
result.put("word","hello, world!");
return result;
}
```
### Actual behavior
```

[INFO] 2021-05-08 15:59:27.011 http-nio-9014-exec-2 com.nolouser.demo.service.impl.TOrderServiceImpl:49 - TOrder{orderId=548438947156963329, userId=9, addressId=9, status=INSERT_TEST, datetime=2020-12-23 09:40:34}
```
From log, we could see that it only executed the first logic sql.
### Reason analyze (If you can)
In the way of executing two same sqls in one transaction, mybatis-plus will actually execute the first one, and gets result of the second one from cache, so ShardingSphere will not work for the second logic sql.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).
[example codes](https://github.com/NOLouser/shardingsphere-demo)
