spring data mongo db：扩展基本域类时出现重复键错误

编程问答 2022-08-15

问题描述

我有一个从BaseDomainObject扩展的域对象，它具有Lombok批注。

@Data
@EqualsAndHashCode(onlyExplicitlyIncluded = true,callSuper = false)
@Document(collection = "SubmissionApplication")
public class SubmissionApplication extends BaseDomainObject {

    @Id
    @JsonProperty("applicationId")
    @EqualsAndHashCode.Include
    private String id;
    private ApplicationSource applicationSource;
    private String applicationCompletionDate;

}

BaseDomainObject.java 

public abstract class BaseDomainObject implements Serializable {
    @CreatedBy
    private String createdBy;
    @CreatedDate
    private Date createdDate;
    @LastModifiedBy
    private String lastModifiedBy;
    private String updateDate;
    @LastModifiedDate
    private Date lastModifiedDate;
    @Version
    private Integer version;
    private String createDate;
    private Boolean active = true;
    private String updatedBy;
    private Integer totalCount;

    public BaseDomainObject() {
    }

    .... getters/setters
}

并且当我尝试repo.save(application)更新现有文档时，出现异常：

com.mongodb.MongoWriteException: E11000 duplicate key error collection: APP.SubmissionApplication index: _id_ dup key: { _id: ObjectId('5f43aef2e878fb1e0b34aab3') }

如果我删除扩展BaseDomainObject，spring数据mongodb将正确更新文档。

我在做什么错了？
