    $user->setId($userSaveResult);
    $deleteResult=$user ->delete()->getResult();

    return compact("resultArray",'userUpdateResult',"userSaveResult",'deleteResult','id');
}

// paste output here
{"msg":"Return value of Swoft\\Db\\QueryBuilder::getConnection() must be an instance of Swoft\\Db\\AbstractDbConnection, null returned","file":"\/var\/www\/swoft\/vendor\/swoft\/db\/src\/QueryBuilder.php","line":855,"code":0}

第一次访问的时候,可以update,第二次更新的时候会比较字段是否需要更新,如果不用更新的话,就会报错

解决方式就是 返回类型 加个?号,但是php 7.1 才支持nullable类型,你们看怎么处理吧.
    /**
     * @return \Swoft\Db\AbstractDbConnection
     */
    public function getConnection(): ?\Swoft\Db\AbstractDbConnection
    {
        return $this->connection;
    }
