我开始学习ZF-2.2但是ServiceManager有问题。
module.config.php
'service_manager' => array(
'abstract_factories' => array(
'Zend\Cache\Service\StorageCacheAbstractServiceFactory',
'Zend\Log\LoggerAbstractServiceFactory',
),
module.php
public function getServiceConfig(){
return array(
'invokables' => array(
'PostDataMapper' => 'student\Model\PostDataMapper',
),
'factories' => array(
'PostIdentityMap' => function ($sm) {
}),
);
}
学生\ SRC \学生\模型\ PostDataMapper.php
namespace student\Model;
class PostDataMapper{
private $dbcon="postgresql";
protected $dbcon1 ="put";
}
学生\ SRC \学生\模型\ PostIdendityMap.php
class PostIdentityMap {
private $datamapper;
public function __construct(PostDataMapper $pdm) {
$this->datamapper = $pdm;
}
}
如果我这样尝试
$pim = $this->getServiceLocator()->get('PostIdentityMap');

答案 0 :(得分:1)
当您使用闭包作为服务工厂时,您需要确保创建并返回所需的实例。
例如
public function getServiceConfig(){
return array(
'invokables' => array(
'PostDataMapper' => 'student\Model\PostDataMapper',
),
'factories' => array(
'PostIdentityMap' => function ($sm) {
return new Model\PostIdendityMap();
}),
);
}
考虑到对象没有构造函数;您可以将定义移动到invokables
配置键。这意味着服务管理器将为您创建实例(无需工厂)。
public function getServiceConfig(){
return array(
'invokables' => array(
'PostDataMapper' => 'student\Model\PostDataMapper',
'PostIdentityMap' => 'student\Model\PostIdendityMap',
),
);
}
也;尝试遵循ZF2 skeleton application naming conventions - 'student'目录应该大写。
