Swoft2.x 小白学习笔记 (二) --- mysql、redis

介绍swoft中

　　1、mysql、

　　2、Redis

 

一、mysql使用：

　　1、配置,在 app\bean.php文件中

   'db' => [
        'class'    => Database::class,
        'dsn'      => 'mysql:dbname=webdemo;host=localhost',
        'username' => 'root',
        'password' => 'foto_cj1',
    ],
//链接池配置
    'db2.pool' => [
        'class'    => Pool::class,
        'database' => bean('db'),
        'minActive'   => 10,
        'maxActive'   => 20,
        'maxWait'     => 0,
        'maxWaitTime' => 0,
        'maxIdleTime' => 60,
    ],

　　2、生成Model，一个Model对应一张表。在 /App/Model/Entity/ 文件夹下新建文件

);

namespace App\Model\Entity;

use Swoft\Db\Annotation\Mapping\Column;
use Swoft\Db\Annotation\Mapping\Entity;
use Swoft\Db\Annotation\Mapping\Id;
use Swoft\Db\Eloquent\Model;

/**
 *
 * Class Demo
 *
 * @since 2.0
 *
 * @Entity(table="demo",pool="db2.pool")  //定义Model,参数是对应的表和连接池(选填)
 */
class Demo extends Model
{
    /**
     *默认自动添加 created_at 和 updated_at,不需要时设置为false
     * @var bool
     */
    public $modelTimestamps = false;

    /**
     *
     * @Id(incrementing=false)
     * @Column(name="id")    //定义列
     *
     * @var int
     */
    private $id;

    /**
     * @Column(name="name")
     *
     * @var string|null
     */
    private $name;

    /**
     * @param int $id
     *
     * @return void
     */
    public function setId(int $id): void
    {
        $this->id = $id;
    }

    /**
     * @param string|null $name
     *
     * @return void
     */
    public function setName(?string $name): void
    {
        $this->name = $name;
    }

    /**
     * @return int
     */
    public function getId(): ?int
    {
        return $this->id;
    }

    /**
     * @return string|null
     */
    public function getName(): ?string
    {
        return $this->name;
    }
}

 　3、使用(Model)    

//查询
    $user = Demo::find($)->toArray();

//修改
    $sdbuser = Demo::find($id);
    $sdbuser->setName("cjcjcjccj");
//或者
    $sdbuser->update(['name' => "dddddd"]);


  //删除
        $result = Demo::where('id', 1)->delete();

        $user = Demo::find($data["uid"]);
        $result = $user->delete();

//插入
        $count = new Demo();
        $count->setId(mt_rand(1, 100));
        $count->setName('attr');
        $result = $count->save();
        $nId = $count->getId();

//批量插入
     $insArr = [
            [
                'id'      => random_int(1, 100),
                'name'  => md5(uniqid())
            ],
            [
                'id'      => random_int(1, 100),
                'name'  => md5(uniqid())
            ]
        ];

    $result = Demo::insert($insArr);

   4、DB原生使用：https://www.swoft.org/docs/2.x/zh-CN/db/builder.html

 

二：Redis简单使用：

1、配置：在 app\bean.php文件中

'redis'             => [
        'class'    => RedisDb::class,
        'host'     => '127.0.0.1',
        'port'     => 6379,
        'database' => 0,
        'option'   => [
            'prefix' => 'swoft:'
        ]
    ],
    'redis.pool'     => [
        'class'   => \Swoft\Redis\Pool::class,
        'redisDb' => \bean('redis'),
        'minActive'   => 10,
        'maxActive'   => 20,
        'maxWait'     => 0,
        'maxWaitTime' => 0,
        'maxIdleTime' => 40,
    ]

2、使用

　　（1）、直接使用

Redis::set($key, $setData，$time);
Redis::get($key);

      (2)、通过 @Inject注入连接池方式使用

　　　　在/App/Http/Controller/中新建文件 

/**
 * Class RedisController
 *
 * @since 2.0
 * @Controller("redis")
 */
class RedisController
{
    /**
     * @Inject("redis.pool")   
     *
     * @var Pool
     */
    private $redis;

    /**
     * @return array
     * @RequestMapping("find")  //访问路由:  /redis/find
     * @throws \Throwable
     */
    public function find()
    {
        $us = $this->redis->get('user');
        if($us)
            $this->redis->set('user', ["name" => "gimi", "age" => "18"],120);

        return $us;
    }
}
