Question

因此，我正在使用Spring Boot和Kotlin。发布对象时，如果数据库中有一个对象，则使用uuid进行查找。如果这样做，我将修改该实例，否则使用一个新实例。

当我查看数据库时，我看到了更新的版本，然后看到了一个新的空行。

我可以看到更新的时间戳，如果我使用调试器来操纵它保存的值。但是总会有一个新行，带有新ID，并且所有字段均为空

服务

@Entity
data class Claim (

    @Id
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    var uuid: String = ""
    )
    {

    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    var claimNo: Long = 0

    var status: ClaimStatus = ClaimStatus.CREATED

    var billingDate: LocalDate = LocalDate.now()

    var lastUpdated: LocalDateTime = LocalDateTime.now()

    var facility: String = ""

    var payProgram: String = ""

    var createdAt:LocalDateTime = LocalDateTime.now()

    var createdBy: String = ""

    var dxCode: String = ""

    var notes: String = ""

    @ManyToOne(cascade = [CascadeType.ALL])
    var patient: Patient = Patient()

    @ManyToOne(cascade = [CascadeType.ALL])
    var doc: Doctor = Doctor()

    @OneToMany(cascade = [CascadeType.ALL], mappedBy = "claim")
    var billedCodes: MutableList<BilledCodes> = mutableListOf<BilledCodes>()

    @PrePersist
    @PreUpdate
    fun updateClaim()
    {
        lastUpdated = LocalDateTime.now()
    }
}

索赔

@Repository
interface ClaimRepository : CrudRepository<Claim, String>

所以答案是我对帐单代码进行映射的方式。删除该关系不再重复保存。

关系需要@Transient标志，而计费代码的映射则需要映射人
