laravel框架事件监听boot用法

控制器：

<?php

namespace App\Http\Controllers;

use App\Base\BaseController;
use App\Service\TestService;
use Symfony\Component\HttpFoundation\Request;

class TestController extends BaseController{

	public function delete(Request $request)
    {
    	$id = $request->input('id');
		$this->service('test')->delete($id);
	}
}

service：

<?php

namespace App\Service;

use App\Base\BaseService;

class TestService extends BaseService
{

    public function delete($id)
    {
        //必须查询后再删除，为了使用deleting监听事件，否则无法调用
        return Test::where(['id' => $id])->first()->delete();
    }
}

Model：

<?php

namespace App\Models;

use App\Base\BaseModel;

class Test extends BaseModel
{
	protected $table   = "test";
    protected $guarded = [];


	public function test1()
    {
        return $this->belongsTo(test1::class, 'test1_id', 'id');
    }


    /**
     *监听事件
     */
    protected static function boot()
    {
        parent::boot();
        //删除前执行-调用方式（需删除对象->delete）
        static::deleting(function($model){
            $model->test1()->delete();
        });

		//creating - 对象已经 ready 但未写入数据库
		//created - 对象已经写入数据库
		//updating - 对象已经修改但未写入数据库
		//updated - 修改已经写入数据库
		//saving - 对象创建或者已更新但未写入数据库
		//saved - 对象创建或者更新已经写入数据库
		//deleting - 删除前
		//deleted - 删除后
		//restoring - 恢复软删除前
		//restored - 恢复软删除后
    }
