你知道 hibernate-enhance-maven-plugin 和 spring-boot-starter-data-elasticsearch 之间的不兼容性吗？

Question

我使用 Hibernate（版本 5.4.27.Final）和 elasticsearch（spring-boot- starter-data-elasticsearch).

我想启用字节码增强延迟加载来提高我的@OneToOne 关系的性能。

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

但是当我启动我的应用程序时，出现以下错误堆栈跟踪：

如果我删除我的应用程序的所有 ElasticSearchRepositories，它会正常工作并且@LazyToOne 字段是延迟加载的。

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

你见过这样的东西吗？

编辑：正如评论中所问，这是我的 elasticsearch 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）。

@Entity

@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@Document(indexName = "language")

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@NotNull
@Column(name = "name", nullable = false, unique = true)
private String name;

@NotNull
@Size(max = 10)
@Column(name = "code", length = 10, nullable = false, unique = true)
private String code;

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

    this.name = name;
    return this;

public Language code(String code) {

}

@Override

    if (this == o) {
        return true;
    }
    if (o == null || getClass() != o.getClass()) {
        return false;
    }
    Language language = (Language) o;
    if (language.getId() == null || getId() == null) {
        return false;
    }
    return Objects.equals(getId(), language.getId());
}

Answer 1

您观察到的第一个错误已在更新的版本中得到修复，即带有 getActualType() 的版本。另一个我无法确定，但我认为 Hibernate 字节码操作 destroys/removes 来自 Spring Data 需要的某些属性类型的信息 - 不仅是 Spring Data Elasticsearch。我想您也没有为关系数据库部分使用 Spring 数据模块。

就我个人而言，我从不使用同一个实体在两个不同的存储中存储数据，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，但经常会导致像这里那样的问题。

我想使用一个实体将数据存储在 Spring Data Elasticsearch 中，另一个实体用于数据库，甚至三分之一用于您的 damain 逻辑；您将需要映射器函数将一个映射到另一个。这是更多类和更多转换，但如果您随后将休眠设置配置为仅处理 DB 实体而不处理用于 SDE 的实体，您将不会遇到这些问题。

你知道 hibernate-enhance-maven-plugin 和 spring-boot-starter-data-elasticsearch 之间的不兼容性吗？

Are you aware of uncomptability between hibernate-enhance-maven-plugin and spring-boot-starter-data-elasticsearch?
