php 互斥锁

锁类型	堵塞类型	分布式	锁时间	多个锁加锁解锁	客户端异常终止(加锁解锁)
互斥锁(Mutex)	堵塞	支持	毫秒级	支持	支持(未实现)
业务互斥锁(BusinessMutex)	堵塞	支持	毫秒级	支持	支持(未实现)
示例订单业务互斥锁(OrderBusinessMutex)	非堵塞	支持	毫秒级	支持	支持(未实现)

仓储类型请使用非堵塞类型

锁仓储类型	是否支持	堵塞类型	多个锁加锁解锁	客户端异常终止(加锁解锁)
Redis	支持	非堵塞	支持	支持
Mysql	支持	非堵塞	支持	支持

优势: 
  1. 提升用户体验
  2. 减少修改代码影响范围
  3. 减少程序修复时间

场景: 
 1. 业务禁止多人同时操作
 2. 业务有单个和批量操作
 2. 订单出库
 3. 新增入库单

安装方式1

创建composer.json文件,并写入以下内容:

{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/qq1060656096/php-sync.git"
        }
    ],
    "require": {
        "zwei/php-sync": "dev-master"
    }
}

执行composer install

使用Mysql仓储请导入sql到数据库中

CREATE TABLE `sync_lock` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'id',
  `name` varchar(255) CHARACTER SET ascii COLLATE ascii_bin NOT NULL COMMENT '锁名',
  `expired` decimal(30,0) NOT NULL COMMENT '有效期多少毫秒',
  `expired_time` decimal(30,0) NOT NULL DEFAULT '0' COMMENT '过期时间',
  `client_id` varchar(255) CHARACTER SET ascii COLLATE ascii_bin NOT NULL COMMENT 'client_id',
  PRIMARY KEY (`id`),
  UNIQUE KEY `uniq_index` (`name`)
) ENGINE=InnoDB AUTO_INCREMENT=1;

示例：订单业务锁示例1

<?php
use Zwei\Sync\Exception\LockFailException;
use Zwei\Sync\Exception\LockTimeoutException;
use Zwei\Sync\Exception\UnLockTimeoutException;
use Zwei\Sync\Helper\Helper;
use Zwei\Sync\Mutex\OrderBusinessMutex;
use Zwei\Sync\Repository\RedisLockRepository;
try {
    $host = '199.199.199.199';
    $post = 16379;
    $password = '000000';
    $redis = new \Redis();
    $redis->connect($host, $post);
    $redis->auth($password);
    
    $redisRepository = new RedisLockRepository($redis);
    $expired = Helper::secondsToMilliseconds(30);
    $orderId = 1;
    $orderDemoBusinessMutex = new OrderBusinessMutex($redisRepository, $expired, $orderId);
    $orderDemoBusinessMutex->lock();
    // todo
    $orderDemoBusinessMutex->unlock();
} catch (LockParamException $exception) {
    // 参数错误
}  catch (LockFailException $exception) {
    // 其他人正在操作, 请稍后在试
} catch (LockTimeoutException $exception) {
    // 加锁超时
} catch (UnLockTimeoutException $exception) {
    // 解锁超时
} catch (NoLockUnLockFailException $exception) {
    // 没有加锁时，解锁
}

    $password = '000000';
    $redis = new \Redis();
    $redis->connect($host, $post);
    $redis->auth($password);

    $redisRepository = new RedisLockRepository($redis);
    $expired = Helper::secondsToMilliseconds(30);
    $orderId = 1;
    $orderBusinessMutex = new OrderBusinessMutex($redisRepository, $expired, $orderId);
    $orderBusinessMutex->synchronized(function(){
        // todo
    });
} catch (LockParamException $exception) {
    // 参数错误
}  catch (LockFailException $exception) {
    // 其他人正在操作, 请稍后在试
} catch (LockTimeoutException $exception) {
    // 加锁超时
} catch (UnLockTimeoutException $exception) {
    // 解锁超时
} catch (NoLockUnLockFailException $exception) {
    // 没有加锁时，解锁
}
