Question

我有一个mongo db集合，它的2个字段设置了复合索引，如下所示

@Document(collection = “customer”)
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@CompoundIndexes({ @CompoundIndex(name = idx1,unique=true ,def = “{‘customerId’ : 1, ‘managerId’: 1}") })
public class CustomerInfo implements Serializable{
private static final long serialVersionUID = -4743404231218445458L;
    private String customerName;
    private Long customerId;
    private Long managerId;
    private Date lastUpdatedTs;
}

现在，当我尝试使用MongoRepository.save（）方法更新集合时，我得到以下异常

Caused by: org.springframework.dao.DuplicateKeyException: Write failed with error code 11000 and error message 'E11000 duplicate key error collection: customerDB.customer index: idx1 dup key: { : 4790, : 17 }'; nested exception is com.mongodb.DuplicateKeyException: Write failed with error code 11000 and error message 'E11000 duplicate key error collection: customerDB.customer index: idx1 dup key: { : 4790, : 17 }'

我知道问题是因为MongoRepository.save（）方法依赖于entityInformation.isNew（）来识别它是一个保存还是更新用例。对我而言，它必须依赖于唯一性复合索引，以确定它是否是更新。对我来说复合索引是mongo集合的主键。任何想法将不胜感激!!
