我在symfony 2.0中使用自己的User类和安全系统的实体提供程序.

我注意到,每次重新加载页面时,symfony都会从db中获取用户:

SELECT t0.id AS id1,t0.username AS username2,t0.salt AS salt3,t0.password AS password4,t0.email AS email5,t0.is_active AS is_active6,t0.credentials AS credentials7 FROM w9_users t0 WHERE t0.id = ？参数:['23']时间:4.43毫秒

有没有简单的方法来禁用此行为？也许在会话变量中序列化用户数据或以某种方式缓存它们？

我正在关注symfony 2的"如何公开Bundle的语义配置"官方手册.

我有我的configuration.php

namespace w9\UserBundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritDoc}
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('w9_user');

        $rootNode
            ->children()
                ->scalarNode('logintext')->defaultValue('Zareejstruj si?')->end()
            ->end()
        ;        

        return $treeBuilder;
    }
}

和w9UserExtension.php:

namespace w9\UserBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;

class w9UserExtension extends Extension
{
    /**
     * {@inheritDoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config')); …
