using var conn = GetDbConnection();
if (conn.State == ConnectionState.Closed)
{
conn.Open();
}
var transaction = conn.BeginTransaction();
await conn.ExInsertAsync(message.MallOrder, transaction, isEnabled: false);
conn.ExInsertBatch(message.MallOrderDetails, "Mall_OrderDetail", transaction, false);
transaction.Commit();
