fengzhongye opened a new issue, #29734:
URL: https://github.com/apache/shardingsphere/issues/29734
## Bug Report
### Which version of ShardingSphere did you use?
```
<dependency>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>shardingsphere-jdbc-core</artifactId>
</dependency>
<dependency>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>shardingsphere-transaction-xa-core</artifactId>
</dependency>
```
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
Updating data based on primary key id will not deadlock
### Actual behavior
Updating data based on primary key id will deadlock
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
This is my class.
```
@Override
@Transactional(isolation = Isolation.READ_COMMITTED)
public UniSegmentId getNextSegmentId(String bizType) {
for (int i = 0; i < TinyIdConstants.RETRY; i++) {
UniIdInfo tinyIdInfo = tinyIdInfoService.queryByBizType(bizType);
if (tinyIdInfo == null) {
throw new TinyIdSysException("找不到业务类型: " + bizType);
}
Long newMaxId = tinyIdInfo.getMaxId() + tinyIdInfo.getStep();
Long oldMaxId = tinyIdInfo.getMaxId();
int row = tinyIdInfoService.updateMaxId(tinyIdInfo.getId(),
newMaxId, oldMaxId, tinyIdInfo.getVersion(), tinyIdInfo.getBizType());
if (row == 1) {
tinyIdInfo.setMaxId(newMaxId);
return convert(bizType, tinyIdInfo);
} else {
log.info("版本号冲突:{}", tinyIdInfo);
}
}
throw new TinyIdSysException("获取下一段冲突");
}
@Slf4j
@RestController
@Tag(name = "订单控制器")
@RequestMapping("/order")
@RequiredArgsConstructor
public class OrderController {
private ExecutorService executorService =
Executors.newVirtualThreadPerTaskExecutor();
@Resource
private IdGeneratorFactory idGeneratorFactoryServer;
@GetMapping
public void get(){
for(int i = 0; i< 10000; i++){
executorService.submit(() -> {
UniIdGenerator orderItemIdGenerator =
idGeneratorFactoryServer.getIdGenerator(TinyIdServiceNameConstant.NORMAL_ORDER_ITEM);
UniIdGenerator orderIdGenerator =
idGeneratorFactoryServer.getIdGenerator(TinyIdServiceNameConstant.NORMAL_ORDER);
log.info("子订单id: {}", orderItemIdGenerator.nextId());
log.info("订单id: {}", orderIdGenerator.nextId());
});
}
}
}
```
The same code, I have no problem using mybatis alone, but introducing
shardingsphere will lead to deadlock
