TP5模型开启事务

和Db开启事务类似,Db是静态方法

$userObj = new UserModel();

$userObj->startTrans();
try {
    $userObj->data($data,true)->isUpdate(false)->allowField(true)->save();
} catch(Exception $e) {
    $userObj->rollback();
    Log::write('error:' . $e->getMessage() . ';行:' . $e->getLine() . ';文件:' . $e->getFile() . ';trace:' . $e->getTraceAsString(),'error');
}

$userObj->commit();
