[英]How to rename id field in an entity using with elasticsearch?
嗨,朋友們,我在Spring Boot項目中使用彈性搜索,我的主要數據庫是mysql。 我的項目在默認配置下運行良好。 假設我的實體是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;
.......
}
現在使用此配置,我的項目正在運行,彈性搜索工作正常,但是我的要求是使reasonCode
主鍵代替id
所以我想刪除
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
此代碼。 當我刪除id字段並設置原因代碼主鍵時,當我運行我的項目時,它給了我這個錯誤:

雖然mysql工作正常,但實體是在mysql數據庫中創建的,而不是在elasticsearch中創建的。 請幫忙!
嘗試在主鍵字段中添加以下注釋:
@Id
@org.springframework.data.annotation.Id
問候。
