laravel分库分表怎样实现
在Laravel中实现分库分表可以通过使用数据库迁移和模型来实现。以下是一个简单的示例:
php artisan make:migration create_users_table --table=db1.users
php artisan make:migration create_posts_table --table=db2.posts
// db1.users migration file
Schema::connection('db1')->create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->timestamps();
});
// db2.posts migration file
Schema::connection('db2')->create('posts', function (Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->text('content');
$table->timestamps();
});
// User model
namespace AppModels;
use IlluminateDatabaseEloquentModel;
class User extends Model
{
protected $connection = 'db1';
protected $table = 'users';
}
// Post model
namespace AppModels;
use IlluminateDatabaseEloquentModel;
class Post extends Model
{
protected $connection = 'db2';
protected $table = 'posts';
}
use AppModelsUser;
use AppModelsPost;
$users = User::all();
$posts = Post::all();
通过以上步骤,我们就能够在Laravel中实现分库分表的功能。在实际项目中,可以根据需求来定义更多的分库分表结构和模型。
