如何在继承自Command.php的类中实现构造函数

使用symfony2.3.4和PHP5.6.3

我正在实现我自己的一个命令，实际上它与原则：generate:entity基本相同，只是有一些我的定制

我一直在尝试在我的类OwnEntityCommand.php中实现构造函数方法，它从GeneratedActineEntityCommand类扩展而来，该类遵循一行向上继承，直到到达Command.php

最后一个类中的构造函数如下所示：

public function __contruct($name = null) {  
    $this->definition = new InputDefinition();  
    $this->ignoreValidationErrors = false;  
    $this->applicationDefinitionMerged = false;  
    $this->applicationDefinitionMergedWithArgs = false;  
    $this->aliases = array();  

    if(null !== $name){  
        $this->setName($name);  
    }  
    $this->configure();  

    if($this->name){  
        throw new \LogicException('The command name cannot be empty.');
    }
}

public function __construct(Filesystem $filesystem, RegistryInterface $registry){  
    $this->filesystem = $filesystem;  
    $this->registry = $registry;  
}

class OwnEntityCommand extends GenerateDoctrineEntityCommand
{
    protected function configure()
    {
        $this
            ->setName('own:entity')
            ->setAliases(array('entity:own'))
            ->setDescription('Generates a new Doctrine entity inside a bundle')
            ->addOption('entity', null, InputOption::VALUE_REQUIRED, 'The entity class name to initialize (shortcut notation)')
            ->addOption('fields', null, InputOption::VALUE_REQUIRED, 'The fields to create with the new entity')
            ->addOption('format', null, InputOption::VALUE_REQUIRED, 'Use the format for configuration files (php, xml, yml, or annotation)', 'annotation')
            ->setHelp(<<<EOT
The <info>%command.name%</info> task generates a new Doctrine
entity inside a bundle:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post</info>
The above command would initialize a new entity in the following entity
namespace <info>Acme\BlogBundle\Entity\Blog\Post</info>.
You can also optionally specify the fields you want to generate in the new
entity:
<info>php %command.full_name% entity:own --entity=AcmeBlogBundle:Blog/Post --fields="title:string(255) body:text"</info>
By default, the command uses annotations for the mapping information; change it
with <comment>--format</comment>:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post --format=yml</info>
To deactivate the interaction mode, simply use the <comment>--no-interaction</comment> option
without forgetting to pass all needed options:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post --format=annotation --fields="title:string(255) body:text" --no-interaction</info>
This also has support for passing field specific attributes:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post --format=annotation --fields="title:string(length=255 nullable=true unique=true) body:text ranking:decimal(precision:10 scale:0)" --no-interaction</info>
EOT
        );
    }

我需要的那个应该是这样的：

public function __contruct($name = null) {  
    $this->definition = new InputDefinition();  
    $this->ignoreValidationErrors = false;  
    $this->applicationDefinitionMerged = false;  
    $this->applicationDefinitionMergedWithArgs = false;  
    $this->aliases = array();  

    if(null !== $name){  
        $this->setName($name);  
    }  
    $this->configure();  

    if($this->name){  
        throw new \LogicException('The command name cannot be empty.');
    }
}

public function __construct(Filesystem $filesystem, RegistryInterface $registry){  
    $this->filesystem = $filesystem;  
    $this->registry = $registry;  
}

class OwnEntityCommand extends GenerateDoctrineEntityCommand
{
    protected function configure()
    {
        $this
            ->setName('own:entity')
            ->setAliases(array('entity:own'))
            ->setDescription('Generates a new Doctrine entity inside a bundle')
            ->addOption('entity', null, InputOption::VALUE_REQUIRED, 'The entity class name to initialize (shortcut notation)')
            ->addOption('fields', null, InputOption::VALUE_REQUIRED, 'The fields to create with the new entity')
            ->addOption('format', null, InputOption::VALUE_REQUIRED, 'Use the format for configuration files (php, xml, yml, or annotation)', 'annotation')
            ->setHelp(<<<EOT
The <info>%command.name%</info> task generates a new Doctrine
entity inside a bundle:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post</info>
The above command would initialize a new entity in the following entity
namespace <info>Acme\BlogBundle\Entity\Blog\Post</info>.
You can also optionally specify the fields you want to generate in the new
entity:
<info>php %command.full_name% entity:own --entity=AcmeBlogBundle:Blog/Post --fields="title:string(255) body:text"</info>
By default, the command uses annotations for the mapping information; change it
with <comment>--format</comment>:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post --format=yml</info>
To deactivate the interaction mode, simply use the <comment>--no-interaction</comment> option
without forgetting to pass all needed options:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post --format=annotation --fields="title:string(255) body:text" --no-interaction</info>
This also has support for passing field specific attributes:
<info>php %command.full_name% --entity=AcmeBlogBundle:Blog/Post --format=annotation --fields="title:string(length=255 nullable=true unique=true) body:text ranking:decimal(precision:10 scale:0)" --no-interaction</info>
EOT
        );
    }

我班上唯一的属性是：

private $filesystem;  
private $registry;

当我尝试运行它抛出的命令时：

[无效辩论例外] 未定义命令“own:entity”

不知道如何实现自己的构造函数而不与父构造函数发生冲突（我认为这就是正在发生的事情）

如果需要更多的数据或代码，请告诉我

更新：

protected function configure() {
$this
        ->setName('own:entity')
        ->setAliases(array('generate:own:entity'))
        ->setDescription('Generates a new Doctrine entity inside a bundle')
        ->addOption('entity', null, InputOption::VALUE_OPTIONAL, 'The entity class name to initialize (shortcut notation)', 'UserBundle:TestEntity')
        ->addOption('fields', null, InputOption::VALUE_REQUIRED, 'The fields to create with the new entity')
        ->addOption('format', null, InputOption::VALUE_REQUIRED, 'Use the format for configuration files (php, xml, yml, or annotation)', 'annotation')
        ->addOption('with-repository', null, InputOption::VALUE_NONE, 'Whether to generate the entity repository or not');

}

我认为您必须覆盖configure函数，才能像这样更改name命令：

public function __contruct($name = null) {  
    $this->definition = new InputDefinition();  
    $this->ignoreValidationErrors = false;  
    $this->applicationDefinitionMerged = false;  
    $this->applicationDefinitionMergedWithArgs = false;  
    $this->aliases = array();  

    if(null !== $name){  
        $this->setName($name);  
    }  
    $this->configure();  

    if($this->name){  
        throw new \LogicException('The command name cannot be empty.');
    }
}

public function __construct(Filesystem $filesystem, RegistryInterface $registry){  
    $this->filesystem = $filesystem;  
    $this->registry = $registry;  
}

class OwnEntityCommand extends GenerateDoctrineEntityCommand
{
    protected function configure()
    {
        $this
            ->setName('own:entity')
            ->setAliases(array('entity:own'))
            ->setDescription('Generates a new Doctrine entity inside a bundle')
            ->addOption('entity', null, InputOption::VALUE_REQUIRED, 'The entity class name to initialize (shortcut notation)')
            ->addOption('fields', null, InputOption::VALUE_REQUIRED, 'The fields to create with the new entity')
            ->addOption('format', null, InputOption::VALUE_REQUIRED, 'Use the format for configuration files (php, xml, yml, or annotation)', 'annotation')
            ->setHelp(<<<EOT
