hyperf 缓存

Cache代理类

Cache代理类 app/Utils/Cache.php

<?php
namespace App\Utils;


use Hyperf\Utils\ApplicationContext;
use Psr\SimpleCache\CacheInterface;

class Cache
{
        public static function getInstance()
        {
                return ApplicationContext::getContainer()->get(CacheInterface::class);
        }

        public static function __callStatic($name, $arguments)
        {
                return self::getInstance()->$name(...$arguments);
        }
}

控制器 app/Controller/IndexController.php

<?php
namespace App\Controller;

use Hyperf\HttpServer\Annotation\AutoController;
use App\Utils\Cache;

/**
 * @AutoController();
 */
class IndexController
{

        public function index(){
                Cache::getInstance()->set('user:1', ['name'=>'huyongjian', 'id'=>'1']);
                $re = Cache::get('user:1');
                return $re;
        }
}

cache配置文件 config/autoload/cache.php

<?php

declare(strict_types=1);

return [
    'default' => [
        'driver' => Hyperf\Cache\Driver\RedisDriver::class,
        'packer' => Hyperf\Utils\Packer\PhpSerializerPacker::class,
        'prefix' => 'c:',
    ],
];

env配置文件 /.env

//redis是docker link的Redis
REDIS_HOST=redis
REDIS_AUTH=(null)
REDIS_PORT=6379
REDIS_DB=0

客户端测试

curl 118.195.173.53:9501/index/index

结果显示

{"name":"huyongjian","id":"1"}

Model缓存

控制器 app/Controller/IndexController.php

<?php
namespace App\Controller;

use Hyperf\HttpServer\Annotation\AutoController;
use App\Model\User;
use Hyperf\Di\Annotation\Inject;
use App\Service\UserService;
use App\Service\SystemService;

/**
 * @AutoController();
 */
class IndexController
{

         /**
         * @Inject()
         * @var UserService
          */
        private $user;

        /**
         * @Inject()
         * @var SystemService
         */
        private $systemService;

        public function getUser(){
                return $this->user->user(1);
        }

        public function updateUser(){
                /** @var User $user */
                $user = User::query()->find(1);
                $user->name = 'HuYongjian'.rand(1,10);
                $user->save();

                $this->systemService->flushUserCache(1);
        }
}

UserService类 app/Service/UserService.php

<?php
namespace App\Service;

use App\Model\User;
use Hyperf\Cache\Annotation\Cacheable;

class UserService
{


        /**
         * @Cacheable(prefix="user", ttl=9000, listener="user-update")
         */
        public function user($id)
        {
                $user = User::query()->where('id',$id)->first();

                if($user){
                        return $user->toArray();
                }

                return null;
        }
}

SystemService类 app/Service/SystemService.php

<?php

declare(strict_types=1);

namespace App\Service;

use Hyperf\Di\Annotation\Inject;
use Hyperf\Cache\Listener\DeleteListenerEvent;
use Psr\EventDispatcher\EventDispatcherInterface;

class SystemService
{
    /**
     * @Inject
     * @var EventDispatcherInterface
     */
    protected $dispatcher;

    public function flushUserCache($userId)
    {
        $this->dispatcher->dispatch(new DeleteListenerEvent('user-update', [$userId]));

        return true;
    }
}

Model类 app/Model/User.php

<?php

declare (strict_types=1);
namespace App\Model;

use Hyperf\DbConnection\Model\Model;
/**
 * @property int $id 
 * @property string $name 
 * @property int $status 
 */
class User extends Model
{
    /**
     * The table associated with the model.
     *
     * @var string
     */
    protected $table = 'user';
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [];

    /**
     * @var bool
     */
    public $timestamps = false;

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = ['id' => 'integer', 'status' => 'integer'];
}

进入MySQL 查看user表记录

select * from user;
+----+-------------+--------+
| id | name        | status |
+----+-------------+--------+
|  1 | HuYongjian6 |      1 |
|  2 | huyongjian2 |      0 |
+----+-------------+--------+

访问测试(多次刷新看是否是缓存数据)

curl 118.195.173.53:9501/index/getUser

{"id":1,"name":"HuYongjian6","status":1}

更新后重新访问getUser (看缓存数据是否改变)

curl 118.195.173.53:9501/index/updateUser
