如何使用Elasticsearch重命名实体中的ID字段？

Question

嗨，朋友们，我在Spring Boot项目中使用弹性搜索，我的主要数据库是mysql。 我的项目在默认配置下运行良好。 假设我的实体是CancelReason.java

@Entity
@Table(name = "cancel_reason")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@Document(indexName = "cancelreason")
public class CancelReason implements Serializable {

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


    @NotNull
    @Size(max = 10)        
    @Column(name = "reason_code", length = 10, nullable = false)
    private String reasonCode;
    .......
}

现在使用此配置，我的项目正在运行，弹性搜索工作正常，但是我的要求是使reasonCode主键代替id所以我想删除

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

此代码。 当我删除id字段并设置原因代码主键时，当我运行我的项目时，它给了我这个错误：

虽然mysql工作正常，但实体是在mysql数据库中创建的，而不是在elasticsearch中创建的。 请帮忙！

尝试在主键字段中添加以下注释：

@Id
@org.springframework.data.annotation.Id

问候。
