概要

IoCConf提供了一种方便的方式，使用xml处理依赖注入。例如，可以使用构造函数或setter注入来设置控制器。

安装

IocConf需要XmlConf才能运行。

将thapp/iocconf和thapp/xmlconf添加到composer.json的要求中

{
    "require": {
        "thapp/iocconf": "1.0.*",
        "thapp/xmlconf": "1.0.*"
    }
}

然后运行composer update或composer install

下一步是告诉Laravel加载serviceprovider。在app/config/app.php中添加

  // ...
  'Thapp\IocConf\IocConfServiceProvider' 
  // ...

到providers数组。

确保XmlConf安装正确，然后告诉XmlConf在哪里找到ioc配置（app/config/packages/thapp/xmlconf/config.php）

return array(

    /*
    |--------------------------------------------------------------------------
    | Basedir relative to the install directory
    |--------------------------------------------------------------------------
     */
    'basedir' => array(
        'ioc'      => 'vendor/thapp/iocconf/src/Thapp/IocConf'
    ),

    /*
    |--------------------------------------------------------------------------
    | Reader dictionary
    |--------------------------------------------------------------------------
     */
    'namespaces' => array(
        'ioc'      => 'Thapp\\IocConf'
    ),
);

示例

假设你想要将Laravel的视图对象注入到控制器中，xml配置可能看起来像这样

<?php

namespace Acme;

use \BaseController;

class FrontController extends BaseController
{

    // ... setter method on your controller
    public function setView(\Illuminate\View\Environment $view)
    {
        $this->view = $view;
    }

}   

配置xml可能看起来像这样

<container xmlns="http://getsymphony.com/schema/ioc">

  <entities>
    <entity class="Acme\FrontController" scope="prototype"/>
        <!-- the controller has a setter method for setting the view object -->
        <call method="setView">
    		<argument id="view"/>
    	</call>
    </entity>
  </entities>

</container>    

用法

xml

注意：实体节点可以有一个id属性，但必须有class和scope属性，参数节点必须具有id或class属性。

可能的实体作用域

- prototype // see Container::bind();
- singleton // see Container::singleton();
- shared    // see Container::share();

<?xml version="1.0" encoding="UTF-8"?>

<container xmlns="http://getsymphony.com/schema/ioc">

  <entities>

    <entity id="acme.frontcontroller" class="FrontController" scope="prototype"/>
    
    <entity id="acme.admincontroller" class="AdminController" scope="prototype">
    	<call method="setView">
    		<argument id="view"/>
    	</call>
    </entity>

    <entity class="ControllerRepository" scope="singleton">
      <argument id="acme.frontcontroller"/>
      <argument id="acme.admincontroller"/>
    </entity>

  </entities>

</container>    

php

$repo = App::make('ControllerRepository');

$repo2 = App::make('ControllerRepository');

$repo === $repo2 // true
