无需创建自己的连接表的解决方案。
我已经修改了我创建的 LoggableListener 以覆盖 Gedmo LoggableListener，我的版本可以正常工作，玩弄这个直到你让它工作。
基本上，使用您自己的版本扩展 Gedmo LoggableListener 并覆盖/添加一些修改后的函数：
prePersistLogEntry 已启用，允许您根据需要修改 logEntry。我的 logEntry 实体包含一个用户实体和用户全名而不是他们的用户名。
getCollectionsChangeSetData 是一个新函数，用于提取集合并访问 Doctrine PersistentCollections 方法。
[http://www.doctrine-project.org/api/orm/2.1/class-Doctrine.ORM.PersistentCollection.html]
stripCollectionArray 新函数，用于从集合实体中提取所需信息并将它们插入到 php 数组中以持久保存到 LogEntry。
有关信息，如果您计划使用 Loggable 原则扩展的恢复功能，那么您还需要扩展和覆盖 LogEntryRepository 中的恢复方法。当前的 revert 方法将无法识别 LogEntry 中保存的 ManyToMany 关联中的 id。这就是为什么 stripCollectionArray 函数还将 'id' 和 'class' 值保存到 LogEntry。
祝你好运。
