出于某种原因，我认为我的'service_manager'配置没有被正确读取。这几乎是一个全新的骨架结帐。也许一天的工作。

我最近又做了一个，并尝试比较。我不知道我哪里出错了。

Controller\DbBuilderController::class => function(ContainerInterface $container, $requestedName) {在该行指向的匿名函数下$userService = $container->get(\Application\Service\UserService::class);导致错误：Unable to resolve service "Application\Service\UserService" to a factory; are you certain you provided it during configuration?

我尝试更改\Application\Service\UserService::class为简短、愚蠢的文字字符串，因此我确信该服务没有被注册。

我不确定为什么会这样。有接盘侠吗？

    {
        $entityManager = $container->get('doctrine.entitymanager.orm_default');

        $user = new \Application\Service\UserService($entityManager);
        return $user;
    }

}

服务：

<?php

namespace Application\Service;

class UserService
{
    protected $entityManager;

    function __construct(\Doctrine\ORM\EntityManager $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function createUser($username, $password)
    {
        $user = new \Application\Entity\User();
        $user->setUserKey($password);
        $user->setUserName($username);
        $user->setIsAdmin(true);

        $this->entityManager->persist($user);
        $this->entityManager->flush();

        return $user;
    }
}

查看 ZF3 服务管理器表明它无法加载工厂类，即class_exists('Application\Service\Factory\UserServiceFactory')失败。

Application使用getAutoloaderConfigModule.php 中的函数或添加到 composer.json 中，确保自动加载器已为命名空间注册：

"autoload": {
    "psr-4": {
        "Application\\": "module/Application/src/"
    }
},

（显然根据需要更改了目录）然后运行 ​​composer update。

如果UserServiceFactory您使用Zend\Loader\StandardAutoloader.
