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',

),
'service_manager' => array(
'factories' => array(

);
?>
testconfig.php.dist
<?php
echo PHP_EOL . "TestConfig.php.dist executed." . PHP_EOL;
return array(
'modules' => array(

'module_paths' => array(

?>
application.config.php
<?php

'module_paths' => array(

);
?>
module.php只是为了完整......
<?php

$resultSetPrototype = new ResultSet();

答案 0 :(得分:2)
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。
答案 1 :(得分:1)
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。
答案 2 :(得分:1)
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.
