上篇讲解了laravel容器的基本使用和原理,这篇继续Application构造方法中的registerBaseServiceProviders方法
在app调用过registerBaseBindings方法后,打印app实例,发现bindings中存放的确实是闭包,shared为true表示单例绑定,instances中表示容器中可以直接复用的实例

下面继续基础服务注册
/**
* Register all of the base service providers.
*
* @return void
*/
protected function registerBaseServiceProviders()
{
// 跳转到register方法
$this->register(new EventServiceProvider($this));
$this->register(new LogServiceProvider($this));
$this->register(new RoutingServiceProvider($this));
}
/**
* Register a service provider with the application.
*
* @param \Illuminate\Support\ServiceProvider|string $provider
* @param bool $force
* @return \Illuminate\Support\ServiceProvider
*/
public function register($provider, $force = false)
{
// 跳转到getProvider
if (($registered = $this->getProvider($provider)) && !$force) {
// $this->registerBaseServiceProvider没进来
return $registered;
}
// If the given "provider" is a string, we will resolve it, passing in the
// application instance automatically for the developer. This is simply
// a more convenient way of specifying your service provider classes.
// 可以看到register方法 是官方更加推荐的注册服务提供者的方式
if (is_string($provider)) {
// 跳转到resolveProvider方法
// new一个provider
// 我们可以传递一个字符串 laravel会自动帮我们解析
// 框架启动后 可以在任何能够拿到app实例地方调用register方法 会执行自定义服务提供者中的register方法 大家可以自行尝试
$provider = $this->resolveProvider($provider);
}
$provider->register();
// If there are bindings / singletons set as properties on the provider we
// will spin through them and register them with the application, which
// serves as a convenience layer while registering a lot of bindings.
// laravel为我们提供了方便的进行绑定的方式 那就是将绑定映射写在对应服务提供者中的对应属性中
// 官方建议没有特殊要求的情况下 写在AppServiceProvider中即可
if (property_exists($provider, ‘bindings‘)) {
foreach ($provider->bindings as $key => $value) {
$this->bind($key, $value);
}
}
if (property_exists($provider, ‘singletons‘)) {
foreach ($provider->singletons as $key => $value) {
$this->singleton($key, $value);
}
}
// 将已经注册的服务保存到app实例中的对应属性中 serviceProviders loadedProviders
// 标识该服务已经注册
$this->markAsRegistered($provider);
// If the application has already booted, we will call this boot method on
// the provider class so it has an opportunity to do its boot logic and
// will be ready for any usage by this developer‘s application logic.
// 如果app已经引导完毕 那么在此刻意调用provider的boot方法
if ($this->isBooted()) {
$this->bootProvider($provider);
}
return $provider;
// 建议每进行一步都打印下app实例 看到容器中属性的变化即可
}
app构造方法中的最后一个registerCoreContainerAliases方法

下篇会从bootstrap/app.php讲解了。发现错误劳烦指教,感谢!
