出于某种原因,我认为我的 'service_manager'
配置没有被正确读取 . 这主要是一个全新的骨架结账 . 也许一天工作 .
我最近做了另一个,并尝试比较 . 我无法弄清楚我哪里出错了 .
在 Controller\DbBuilderController::class => function(ContainerInterface $container, $requestedName) {
指向的匿名函数下,行 $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?
我已经尝试将 \Application\Service\UserService::class
更改为简短,愚蠢的文字字符串,因此我确信该服务未被注册 .
我不确定为什么会这样 . 任何接受者?

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 .确保自动加载器已为
Application
命名空间注册,使用Module.php中的getAutoloaderConfig
函数或添加到composer.json中:(显然,根据需要更改了目录)然后运行composer update .
如果您正在使用
Zend\Loader\StandardAutoloader
,也可以检查包含UserServiceFactory
的目录结构是否存在拼写错误 .
