您是否知道 hibernate-enhance-maven-plugin 和 spring-boot-starter-data-elasticsearch 之间的不兼容性？

【问题描述】：

我正在使用 Hibernate（版本 5.4.27.Final）和弹性搜索（spring-boot-starter-data-elasticsearch）开发一个 spring-boot 项目（版本 2.3.8.RELEASE）。

我想启用字节码增强延迟加载以提高我的@OneToOne 关系的性能。

我在这篇 Hibernate LazyToOne annotation 文章之后将 hibernate-enhance-maven-plugin 添加到了我的配置中。

但是当我启动我的应用程序时，我得到了以下错误堆栈跟踪：

如果我删除我的应用程序的所有 ElasticSearchRepositories，它可以正常工作，并且 @LazyToOne 字段可以很好地延迟加载。

错误似乎来自 Spring Data 的 Elasticsearch 实现...

你见过这样的事情吗？

编辑：正如 cmets 所要求的，这是我的弹性搜索实体之一，它也是我的 postgres 数据库中的一个实体（由休眠提供支持）。

【问题讨论】：

  • 请显示您在 Spring Data Elasticsearch 中使用的实体类的代码。你是否也使用这些实体类来存储在一些具有休眠功能的关系数据库中？
  • 您好，感谢您的评论。我用我的一个实体类编辑了我的帖子。实际上，这个实体被 elasticsearch 使用，并且在我的带有休眠的关系数据库中也是如此。

标签： java spring-boot hibernate spring-data spring-data-elasticsearch


【解决方案1】：

您观察到的第一个错误已在更新的版本中得到修复，即getActualType()。另一个我无法确定，但我认为 Hibernate 字节码操作会破坏/删除 Spring Data 需要的某些属性类型中的信息——不仅仅是 Spring Data Elasticsearch。我想您也没有将 Spring Data 模块用于关系数据库部分。

就我个人而言，我从不使用相同的实体将数据存储在两个不同的存储中，或者存储它们并将它们传递出去，例如通过 REST 接口。一开始这可能很方便，但通常会导致类似这里的问题。

我想使用一个实体将数据存储在 Spring Data Elasticsearch 中，而另一个用于数据库的实体可能甚至是您的 daomain 逻辑的三分之一；您需要映射器函数将一个映射到另一个。那是更多的类和更多的转换，但是如果您随后将 hibernate 设置配置为仅处理 DB 实体而不处理用于 SDE 的实体，您将不会遇到这些问题。
