annotations - 从 db 模式生成带注释的学说 2 实体

Question

是否可以从现有的数据库模式生成带有相关 docblock 注释的 Doctrine 2 实体？

Answer 1

我必须进行这些更改才能使上述代码正常工作..

<?php 
use Doctrine\ORM\Tools\EntityGenerator;
ini_set("display_errors", "On");
$libPath = __DIR__; // Set this to where you have doctrine2 installed
// autoloaders
require_once $libPath . '/Doctrine/Common/ClassLoader.php';

$classLoader = new \Doctrine\Common\ClassLoader('Doctrine', $libPath);
$classLoader->register();

$classLoader = new \Doctrine\Common\ClassLoader('Entities', __DIR__);
$classLoader->register();

$classLoader = new \Doctrine\Common\ClassLoader('Proxies', __DIR__);
$classLoader->register();

// config
$config = new \Doctrine\ORM\Configuration();
$config->setMetadataDriverImpl($config->newDefaultAnnotationDriver(__DIR__ . '/Entities'));
$config->setMetadataCacheImpl(new \Doctrine\Common\Cache\ArrayCache);
$config->setProxyDir(__DIR__ . '/Proxies');
$config->setProxyNamespace('Proxies');


$connectionParams = array(
    'path' => 'test.sqlite3',
    'driver' => 'pdo_sqlite',
);

$em = \Doctrine\ORM\EntityManager::create($connectionParams, $config);

// custom datatypes (not mapped for reverse engineering)
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('set', 'string');
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('enum', 'string');

// fetch metadata
$driver = new \Doctrine\ORM\Mapping\Driver\DatabaseDriver(
    $em->getConnection()->getSchemaManager()
);
$em->getConfiguration()->setMetadataDriverImpl($driver);
$cmf = new \Doctrine\ORM\Tools\DisconnectedClassMetadataFactory($em);
$cmf->setEntityManager($em); 
$classes = $driver->getAllClassNames();
$metadata = $cmf->getAllMetadata(); 
$generator = new EntityGenerator();
$generator->setUpdateEntityIfExists(true);
$generator->setGenerateStubMethods(true);
$generator->setGenerateAnnotations(true);
$generator->generate($metadata, __DIR__ . '/Entities');
print 'Done!';
?>

和mysql连接配置，如：

$connectionParams = array(
    'driver' => 'pdo_mysql',
    'host' => 'localhost',
    'port' => '3306',
    'user' => 'root',
    'password' => 'root',
    'dbname' => 'database',
    'charset' => 'utf8',
);

是的，尽管 RDBMS 数据类型不完全受支持，但在项目中使用它之前，您可能需要先尝试一下您的代码。它不像 Doctrine 1.x 过去那样简单，但仍然相当容易。这是我自己使用的一些示例代码（在使用之前正确创建文件夹）

使用 Doctrine\ORM\Tools\EntityGenerator；

ini_set("display_errors", "On");

$libPath = __DIR__ 。'/../lib/doctrine2';

// 自动加载器
需要一次 $libPath 。'/Doctrine/Common/ClassLoader.php';

$classLoader = new \Doctrine\Common\ClassLoader('Doctrine', $libPath);
$classLoader->register();

$classLoader = new \Doctrine\Common\ClassLoader('Entities', __DIR__);
$classLoader->register();

$classLoader = new \Doctrine\Common\ClassLoader('Proxies', __DIR__);
$classLoader->register();

// 配置
$config = 新的 \Doctrine\ORM\Configuration();
$config->setMetadataDriverImpl($config->newDefaultAnnotationDriver(__DIR__ . '/Entities'));
$config->setMetadataCacheImpl(new \Doctrine\Common\Cache\ArrayCache);
$config->setProxyDir(__DIR__ . '/Proxies');
$config->setProxyNamespace('代理');


$connectionParams = 数组（
    'dbname' => 'xx',
    '用户' => 'root',
    '密码' => '',
    '主机' => '本地主机'，
    '驱动程序' => 'pdo_mysql',
);

$em = \Doctrine\ORM\EntityManager::create($connectionParams, $config);

// 自定义数据类型（未映射用于逆向工程）
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('set', 'string');
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('enum', 'string');

// 获取元数据
$driver = 新的 \Doctrine\ORM\Mapping\Driver\DatabaseDriver(
    $em->getConnection()->getSchemaManager()
);
$classes = $driver->getAllClassNames();
foreach ($classes 作为 $class) {
    //任何不支持的表/模式都可以在这里处理以排除某些类
    如果真实） {
        $metadata[] = $cmf->getMetadataFor($class);
    }
}

$em->getConfiguration()->setMetadataDriverImpl($driver);
$cmf = new \Doctrine\ORM\Tools\DisconnectedClassMetadataFactory($em);

$generator = new EntityGenerator();
$generator->setUpdateEntityIfExists(true);
$generator->setGenerateStubMethods(true);
$generator->setGenerateAnnotations(true);
$generator->generate($metadata, __DIR__ . '/Entities');

打印“完成！”；

我已经实现了新命令来实现这一点https://github.com/umpirsky/doctrine2/blob/master/lib/Doctrine/ORM/Tools/Console/Command/GenerateEntitiesDbCommand.php

只需像这样添加它：

$cli->addCommands(array(
// DBAL Commands
new \Doctrine\DBAL\Tools\Console\Command\RunSqlCommand(),
new \Doctrine\DBAL\Tools\Console\Command\ImportCommand(),

// ORM Commands
new \Doctrine\ORM\Tools\Console\Command\ClearCache\MetadataCommand(),
new \Doctrine\ORM\Tools\Console\Command\ClearCache\ResultCommand(),
new \Doctrine\ORM\Tools\Console\Command\ClearCache\QueryCommand(),
new \Doctrine\ORM\Tools\Console\Command\SchemaTool\CreateCommand(),
new \Doctrine\ORM\Tools\Console\Command\SchemaTool\UpdateCommand(),
new \Doctrine\ORM\Tools\Console\Command\SchemaTool\DropCommand(),
new \Doctrine\ORM\Tools\Console\Command\EnsureProductionSettingsCommand(),
new \Doctrine\ORM\Tools\Console\Command\ConvertDoctrine1SchemaCommand(),
new \Doctrine\ORM\Tools\Console\Command\GenerateRepositoriesCommand(),
new \Doctrine\ORM\Tools\Console\Command\GenerateEntitiesCommand(),
new \Doctrine\ORM\Tools\Console\Command\GenerateEntitiesDbCommand(),
new \Doctrine\ORM\Tools\Console\Command\GenerateProxiesCommand(),
new \Doctrine\ORM\Tools\Console\Command\ConvertMappingCommand(),
new \Doctrine\ORM\Tools\Console\Command\RunDqlCommand(),
new \Doctrine\ORM\Tools\Console\Command\ValidateSchemaCommand(),

)); $cli->运行（）；

从https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/Tools/Console/ConsoleRunner.php开始，Doctrine 的默认 CLI 已经支持生成实体
