如何使用Elasticsearch重命名实体中的ID字段？

Question

Hi friends i am using elastic search with spring boot project and my primary database is mysql. My project is running fine with default configuration . Suppose my entity is 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;
    .......
}

Now with this configuration my project is running and elastic search is working fine but my requirment is to make reasonCode primary key instead of id so i want to remove

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

this code. as i remove id field and make reasonCode primarykey and when i run my project it gives me this error:

[WARN] org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt

Try adding this annotations in the primary key field:

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