在Laravel 4中创建命名空间

Question

I am struggling to set up a working name space in Laravel 4, I've read some guides on here and in the code bright book. But I still can't seem to figure it out. My app is set up as follows:

app/controllers/itemController app/services/itemValidator

in my composer json file (which I dump-autoload evertime it gets changed) I have:

"autoload": {
    "classmap": [
        <usual data...>
        "app/repositories",
        "app/services",
    ],
    "psr-0": {
        "Services": "app/services/"
    }

my items controller is set up as:

<?php
use Services\ItemValidator;

class ItemsController extends BaseController {

public function store()
{
   $validator = new ItemValidator;
.....etc.....

and my ItemsValidator class is set up as:

 <?php namespace Services;

 class ItemValidator extends BaseValidator
 {
 ....code....

Which gives me the following error when it gets to the $validator = new ItemValidator line:

Class 'Services\ItemValidator' not found 

Answer 1

Just to clarify: according to comments, what works in this case is a composer.json formatted this way:

"autoload": {
    "classmap": [
        <usual data...>
        "app/repositories",
        "app/services",       <---- this is the only entry needed to autoload your services
    ],

Then you should execute

composer dump-autoload

And check if your class appeared in the file

vendor/composer/autoload_namespaces.php
