Question

我收到错误：Zend \ ServiceManager \ Exception \ ServiceNotCreatedException：创建“Zend \ Db \ Adapter \ Adapter”时引发异常;没有实例返回。

追踪它，我发现Zend \ Db \ Adapter \ Adapter在global.php中显示。但是，global.php永远不会被调用，或至少在module.php getserviceconfig（）之前没有被调用，其中错误是跳闸。 testconfig.php.dist和application.config.php都将global.php呈现给侦听器定义。但是，global.php永远不会执行。

有人可以告诉我为什么吗？定义如下。

global.php

<?php
echo PHP_EOL . "Global.php executed." . PHP_EOL;
return array(
    'db' => array(
        'driver'         => 'Pdo',
        'dsn'            => 'mysql:dbname=zf2tutorial;host=album.techmate.com',
        'driver_options' => array(
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        ),
    ),
    'service_manager' => array(
        'factories' => array(
            'Zend\Db\Adapter\Adapter'
                    => 'Zend\Db\Adapter\AdapterServiceFactory',
        ),
    ),
);
?>

testconfig.php.dist

<?php

echo PHP_EOL . "TestConfig.php.dist executed." . PHP_EOL;
return array(
    'modules' => array(
        'Album', // <-- Add this line
    ),
    'module_listener_options' => array(
        'config_glob_paths' => array(
            'config/autoload/{,*.}{global,local}.php',
        ),
        'module_paths' => array(
            './module',
            './vendor',
        ),
    ),
);
?>

application.config.php

<?php
echo PHP_EOL . "Application.config.php executed." . PHP_EOL;
return array(
    'modules' => array(
        'Album',                  // <-- Add this line
    ),
    'module_listener_options' => array(
        'config_glob_paths'    => array(
            'config/autoload/{,*.}{global,local}.php',
        ),
        'module_paths' => array(
            './module',
            './vendor',
        ),
    ),
);
?>

module.php只是为了完整......

Answer 1

根据PHPUnit bootstrapping instructions，在TestConfig.php.dist中看起来似乎以下行可能有误：

'config/autoload/{,*.}{global,local}.php',

将行更改为：

'../../../config/autoload/{,*.}{global,local}.php',

如果您有一个local.php配置文件，它也可能无法加载。

当然，如果目录结构是非标准的，那么相应地更改一行，但你明白了。

Answer 2

我认为global.php没有自动加载，因为文件的命名不匹配：

'config/autoload/{,*.}{global,local}.php',

因此，如果您将文件命名为myconfig.global.php，则应将其取出。

Answer 3

我找到了解决这个问题的方法，但是我非常失望。阅读ZF2手册，我发现了一个注释，即global.php和local.php应该由ModuleManager与module.config.php合并。从我看到的，这实际上应该发生在ModuleManagerFactory但是......

无论如何，我手动将global.php和local.php信息添加到module.config.php中。这有效，但同样，它不应该是必要的。

与往常一样，我很乐意得到比这更好的答案。

为了清楚起见，我提供了手动参考。它来自第700页。请注意，它还包含一个调用文件my.global.config.php和my.local.config.php的错误。我确实尝试过这些名字以防万一，但是没有用。

154.5 Default Configuration Options
The following options are available when using the default services configured by the ServiceManagerConfig
and ViewManager.
These configuration directives can go to the config/autoload/{,*.}{global,local}.php files, or in the
module/<module name>/config/module.config.php configuration files. The merging of these configuration
files is done by the ModuleManager. It first merges each module’s module.config.php file, and then
the files in config/autoload (first the *.global.php and then the *.local.php files). The order of the
merge is relevant so you can override a module’s configuration with your application configuration. If you have both
a config/autoload/my.global.config.php and config/autoload/my.local.config.php, the
local configuration file overrides the global configuration.
