缓存清除时的mongodb LockException错误

Question

我最近在我的 symfony 3.4 项目中添加了"doctrine/mongodb-odm-bundle": "^3.5"，但是一旦我想运行任何命令或第一次尝试调用端点，我就会得到 LockException.php line 69:

Invalid version field type integer. Version field must be int or date. 想知道是否有人可以帮助我 异常跟踪： at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/LockException.php:69 Doctrine\ODM\MongoDB\LockException::invalidVersionFieldType() at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataInfo.php:2074 Doctrine\ODM\MongoDB\Mapping\ClassMetadataInfo->setVersionMapping() at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataInfo.php:1461 Doctrine\ODM\MongoDB\Mapping\ClassMetadataInfo->mapField() at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadata.php:77 Doctrine\ODM\MongoDB\Mapping\ClassMetadata->mapField() at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/Driver/XmlDriver.php:218 Doctrine\ODM\MongoDB\Mapping\Driver\XmlDriver->addFieldMapping() at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/Driver/XmlDriver.php:173 Doctrine\ODM\MongoDB\Mapping\Driver\XmlDriver->loadMetadataForClass() at /home/neda/project/community/vendor/doctrine/persistence/lib/Doctrine/Common/Persistence/Mapping/Driver/MappingDriverChain.php:77 Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain->loadMetadataForClass() at /home/neda/project/community/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataFactory.php:160 Doctrine\ODM\MongoDB\Mapping\ClassMetadataFactory->doLoadMetadata() at /home/neda/project/community/vendor/doctrine/persistence/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php:304 Doctrine\Common\Persistence\Mapping\AbstractClassMetadataFactory->loadMetadata() at /home/neda/project/community/vendor/doctrine/persistence/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php:183 Doctrine\Common\Persistence\Mapping\AbstractClassMetadataFactory->getMetadataFor() at /home/neda/project/community/vendor/doctrine/persistence/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php:89 Doctrine\Common\Persistence\Mapping\AbstractClassMetadataFactory->getAllMetadata() at /home/neda/project/community/vendor/doctrine/mongodb-odm-bundle/CacheWarmer/ProxyCacheWarmer.php:78 Doctrine\Bundle\MongoDBBundle\CacheWarmer\ProxyCacheWarmer->getClassesForProxyGeneration() at /home/neda/project/community/vendor/doctrine/mongodb-odm-bundle/CacheWarmer/ProxyCacheWarmer.php:66 Doctrine\Bundle\MongoDBBundle\CacheWarmer\ProxyCacheWarmer->warmUp() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/CacheWarmer/CacheWarmerAggregate.php:52 Symfony\Component\HttpKernel\CacheWarmer\CacheWarmerAggregate->warmUp() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php:681 Symfony\Component\HttpKernel\Kernel->initializeContainer() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php:135 Symfony\Component\HttpKernel\Kernel->boot() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php:152 Symfony\Component\HttpKernel\Kernel->reboot() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Command/CacheClearCommand.php:199 Symfony\Bundle\FrameworkBundle\Command\CacheClearCommand->warmup() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Command/CacheClearCommand.php:133 Symfony\Bundle\FrameworkBundle\Command\CacheClearCommand->execute() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/Console/Command/Command.php:255 Symfony\Component\Console\Command\Command->run() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/Console/Application.php:981 Symfony\Component\Console\Application->doRunCommand() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Console/Application.php:86 Symfony\Bundle\FrameworkBundle\Console\Application->doRunCommand() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/Console/Application.php:254 Symfony\Component\Console\Application->doRun() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Console/Application.php:74 Symfony\Bundle\FrameworkBundle\Console\Application->doRun() at /home/neda/project/community/vendor/symfony/symfony/src/Symfony/Component/Console/Application.php:147 Symfony\Component\Console\Application->run() at /home/neda/project/community/bin/console:28

您正在您的一个文档（映射为@Version 的字段）中使用版本控制，并且它的类型不是 int 也不是日期，如异常所述。 Int 和 date 字段类型是唯一可以与 @Version (docs for reference) 结合使用的字段类型
