Question

美好的一天。我已经在第二天了，我无法理解其中的问题......我在运行时收到错误：

PHP致命错误：未捕获的异常＆＃39;学说\ ORM \映射\ MappingException＆＃39;有消息＆＃39; The 目标实体Entity \ ItemsBags无法找到＆＃39;实体\玩家＃itemsBag＆＃39;＆＃39;在 /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:762 堆栈跟踪：＃0 /无功/网络/供应商/教义/ ORM / LIB /学说/ ORM /映射/ ClassMetadataInfo.php（1028）：学说\ ORM \制图\ MappingException :: invalidTargetEntityClass（＆＃39;实体\\ ItemsBag ...＆＃39 ;, ＆＃39;实体\\玩家＆＃39;，＆＃39; itemsBag＆＃39;）＃1 /无功/网络/供应商/教义/ ORM / LIB /学说/ ORM /映射/ ClassMetadataFactory.php（272）：教义\ ORM \映射\ ClassMetadataInfo-＆GT; validateAssociations（）＃2 /无功/网络/供应商/教义/ ORM / LIB /学说/ ORM /映射/ ClassMetadataFactory.php（251）：教义\ ORM \映射\ ClassMetadataFactory-＆GT; validateRuntimeMetadata（对象（学说\ ORM \映射\ ClassMetadata），空值）＃3 /无功/网络/供应商/教义/普通/ LIB /学说/普通/持久性/映射/ AbstractClassMetadataFactory.php（332）： Doctrine \ ORM \ Mapping \ ClassMetadataFactory-＆gt; doLoadM in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php 在762行

当我检查学说和更新时，一切顺利：

root @ comp：#php vendor / bin / doctrine orm：schema：update --force更新数据库架构...数据库架构更新成功！＆＃34; 4＆＃34;查询被处决了

root @ comp：#php vendor / bin / doctrine orm：validate-schema [Mapping]好的 - 映射文件是正确的。 [数据库]正常 - 数据库架构与映射文件同步。

我尝试清除缓存，删除代理并重新生成它们，但没有任何结果......

     * @JoinColumn(name="player_id", referencedColumnName="id")
     */
    private $player;

    ...

}

请告诉我，我做错了什么？

Answer 1

感谢@Sarcoma。我忘了在composer.json中指定自动加载部分

  "autoload": {
    "psr-4": { "": "core/" }
  },

P.S可以告诉我，为什么我的项目之前正常运行？）在我有很多内容之前，我的composer.json中没有那个部分，但一切正常。

Doctrine MappingException with message＆＃39;目标实体Entity \\ ItemsBags在＆＃39; Entity \\ Players＃itemsBag＆＃39;
