Symfony服务模式

我正在尝试在symfony2中配置服务：

服务.yml

我有一个错误：

ClassNotFoundException: Attempted to load class "TrendioRest" from namespace "Trendio\DelivBundle\Services" in /var/www/deliv/app/cache/dev/appDevDebugProjectContainer.php line 3176. Do you need to "use" it from another namespace?

TrendioRest.php

---

但，若我将类移动到顶级绑定名称空间Trendio\DeliverBundle，服务将正常工作。为什么类不从子文件夹名称空间加载

使用Symfony类是最佳实践

因为您可以这样简化它：

parameters:
    trendio.rest.backend_ip: 192.168.0.102

services:
    _defaults:
        autowire: true 

    Trendio\DelivBundle\TrendioUserProvider: ~
    Trendio\DelivBundle\Services\TrendioRest:
        arguments: [%trendio.rest.backend_ip%]

---

能否指定包含TrendioRest类的文件的路径？是否按照PSR-0进行放置？如果使用Symfony2而不进行任何自定义，则路径应为/src/Trendio/delivebundle/Services/TrendioRest.phpYes，路径为{root}/src/Trendio/delivebundle/Services/TrendioRest.php

<?php

namespace Trendio\DelivBundle\Services;

class TrendioRest { ... }

parameters:
    trendio.rest.backend_ip: 192.168.0.102

services:
    _defaults:
        autowire: true 

    Trendio\DelivBundle\TrendioUserProvider: ~
    Trendio\DelivBundle\Services\TrendioRest:
        arguments: [%trendio.rest.backend_ip%]
