annotations - 从数据库模式生成带注释的学说2实体

是否可以从现有数据库模式中生成带有相关docblock注释的Doctrine 2实体？

最佳答案

为了使上面的代码起作用，我必须进行这些更改。

<?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的连接配置如:

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