Swoft 容器使用

 

可以借助Swoft下的Bean类操作容器

示例:

将类绑定至容器

use SwoftBeanAnnotationBean;

/**
 * @Bean("imageLogic")
 */
class ImageLogic extends BaseLogic
{
    /**
     * 根据id获取图片
     * @param int $id
     * @return array
     */
    public static function getOne(int $id): array
    {
        return Query::table(Image::class)->where('id',$id)->limit(1)->get(['url','thumb_url'])->getResult();
    }
}

从容器中取出对象:

方法一:注入

use SwoftBeanAnnotationInject;
use AppModelsLogicImageLogic;

class IndexController{
    /**
     * @Inject("imageLogic")
     * @var ImageLogic
     */
    private $imageLogic;
  
    public function index()
    {
        $this->imageLogic->getOne();
    }         
}

方法二:通过 BeanFactory 类获取

use SwoftBeanBeanFactory;

class IndexController
{
    /**
     * @RequestMapping(route="index",method=RequestMethod::GET)
     */
    public function index(Request $request){
        //判断容器中是否存在该实例
        var_dump(BeanFactory::hasBean('imageLogic'));
        //从容器中获取
        $bean = BeanFactory::getBean('imageLogic');
        return $bean->getOne();
    }

}
