Question

当我正在尝试加载我的symfony 2应用程序时，这个问题就出现了，

AppKernel.php第25行中的ClassNotFoundException：尝试从命名空间“Sonata \ DoctrineORMAdminBundle”加载类“SonataDoctrineORMAdminBundle”。您是否忘记了另一个命名空间的“use”语句？

这是我的AppKernel.php文件，

    <?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new AppBundle\AppBundle(),
            new kcc\AdminBundle\kccAdminBundle(),
            new JMS\SerializerBundle\JMSSerializerBundle(),
            new Sonata\CoreBundle\SonataCoreBundle(),
            new Sonata\BlockBundle\SonataBlockBundle(),
            new Knp\Bundle\MenuBundle\KnpMenuBundle(),
            new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
            new Sonata\AdminBundle\SonataAdminBundle(),
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'), true)) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    }
}

我也试图更新作曲家，但由于这个问题它也无法更新

Answer 1

首先要做的事情。您确定您的composer.json文件包含以下标记为＆lt; ==重要：

的条目

@RequestMapping(
        method = RequestMethod.GET,
        path = "/mappings")
@ResponseStatus(HttpStatus.OK)
@ApiImplicitParams({
        @ApiImplicitParam(name = "page", dataType = "int", paramType = "query"),
        @ApiImplicitParam(name = "size", dataType = "int", paramType = "query"),
        @ApiImplicitParam(name = "sort", dataType = "string",  paramType = "query", allowMultiple = true),
        @ApiImplicitParam(name = RestConfiguration.HEADER_ACCEPT_LANGUAGE, dataType = "string",  paramType = "header", defaultValue = RestConfiguration.DEFAULT_LOCALE_TAG)
})
public PagedResources<MappingResource> getMappings(@ApiParam(required = true) @PathVariable final Integer customerId,
                                                   @ApiIgnore @PageableDefault final Pageable pageable,
                                                   HttpServletRequest request) {

    ApplicationResourcesValidator.validateCustomerId(customerId);
    if (customerRepository.findOne(customerId) == null) {
        throw new CustomerNotFoundException(customerId);
    }

    customerIdProvider.set(customerId);

    Page<UserdbFormMapping> mappings = userdbFormMappingRepository.findAllIfUserdbValid(pageable);

    MappingResourceAssembler mappingResourceAssembler = new MappingResourceAssembler(
            MappingController.class,
            MappingResource.class,
            customerId,
            facebookApiClient,
            userdbRepository,
            userdbFormMappingRepository,
            userdbFormMappingFieldRepository,
            userdbFormSubscriptionLogCacheRepository,
            persistenceManager);

    LOGGER.info("serving " + request.getRequestURI());

    return mappingPagedResourceAssembler.toResource(mappings, mappingResourceAssembler);
}

Answer 2

写在documentation中，你必须由作曲家安装SonataDoctrineORMAdminBundle：

composer require sonata-project/doctrine-orm-admin-bundle

如果您按照instructions on the symfony page进行操作可能会有帮助。

Answer 3

只需运行此命令

composer install/update
