如何自动为phpstorm中的类生成属性? [英] How to automate property generation for a class in phpstorm?

问题描述

如果我实现一个类，并注入了一些服务，则必须编写以下大量代码:

If I implement a class, which gets some services injected, I have to write this bulk of code:

<?php
namespace Hn\AssetDbBundle\Services;

use Psr\Log\LoggerInterface;
use Symfony\Bundle\TwigBundle\TwigEngine;
use Symfony\Component\HttpKernel\KernelInterface;

/**
 * Class SomeNewService
 * @package Hn\AssetDbBundle\Services
 */

class SomeNewService {
    /**
     * @var TwigEngine
     */
    private $engine;
    /**
     * @var KernelInterface
     */
    private $kernel;
    /**
     * @var LoggerInterface
     */
    private $logger;

    public function __construct(TwigEngine $engine, KernelInterface $kernel, LoggerInterface $logger) {
        $this->engine = $engine;
        $this->kernel = $kernel;
        $this->logger = $logger;
    }
}

这似乎是多余的.有什么办法可以减少必须编写的代码量?是否有用于初始化字段的实时模板，否则我可以自动生成该块的大部分内容吗?

This seems redundant. Is there a way I can reduce the amount of code I have to write? Is there a live template for initializing the fields or can I autogenerate the bulk of this block otherwise?

推荐答案

您可以使用Initialize field功能.

这样，您只需要这样编写构造方法:

This way, you only have to write the constructor method this way:

class SomeNewService {
    public function __construct(TwigEngine $engine, KernelInterface $kernel, LoggerInterface $logger) {        
    }
}

然后，您可以使用初始化字段.将光标移到构造函数的一个属性上，然后在MacOS上使用 Alt + Enter .

Then you can use initialize fields. Get the cursor over one property of the constructor, then on MacOS use Alt + Enter.

它看起来像这样:

按Enter键后，您将看到一个属性列表，可以通过 Shift 和箭头键进行选择.通过选择所有属性，您的代码将如下所示:

After you press enter you are confronted with a list of properties, which you can select by Shift and arrow keys. By selection all the properties, your code will look like this:

    class SomeNewService {
    /**
     * @var TwigEngine
     */
    private $engine;
    /**
     * @var KernelInterface
     */
    private $kernel;
    /**
     * @var LoggerInterface
     */
    private $logger;

    /**
     * @param TwigEngine $engine
     * @param KernelInterface $kernel
     * @param LoggerInterface $logger
     */
    public function __construct(TwigEngine $engine, KernelInterface $kernel, LoggerInterface $logger) {
        $this->engine = $engine;
        $this->kernel = $kernel;
        $this->logger = $logger;
    }
}
