Item 和 Commit不在一个事务的问题

[iambiglee]

各位大佬们，想问个简单的事务问题：
com.ctrip.framework.apollo.adminservice.controller.ItemController#create

public ItemDTO create(@PathVariable("appId") String appId,
                      @PathVariable("clusterName") String clusterName,
                      @PathVariable("namespaceName") String namespaceName, @RequestBody ItemDTO dto) {
  Item entity = BeanUtils.transform(Item.class, dto);

  ConfigChangeContentBuilder builder = new ConfigChangeContentBuilder();
  Item managedEntity = itemService.findOne(appId, clusterName, namespaceName, entity.getKey());
  if (managedEntity != null) {
    throw new BadRequestException("item already exists");
  }
  entity = itemService.save(entity);
  builder.createItem(entity);
  dto = BeanUtils.transform(ItemDTO.class, entity);

  Commit commit = new Commit();
  commit.setAppId(appId);
  commit.setClusterName(clusterName);
  commit.setNamespaceName(namespaceName);
  commit.setChangeSets(builder.build());
  commit.setDataChangeCreatedBy(dto.getDataChangeLastModifiedBy());
  commit.setDataChangeLastModifiedBy(dto.getDataChangeLastModifiedBy());
  commitService.save(commit);

  return dto;
}

在该方法中，itemService.save(entity) 和 commitService.save(commit) 在各自的事务中都是加了@Transaciton来确保各自的Service方法的事务一致，那为什么没有将整个ItemController#create 放在一个事务中呢？

I think it's better to mark this method with @Transactional.

Thanks for your advice.
