问题描述

我想通过 Id 更新表格，但是当从邮递员端应用数据时，我在我的 intleij 控制台中发现了这种类型的异常

package com.nilmani.onetooneunidirectional.entiry

import com.fasterxml.jackson.annotation.JsonManagedReference

@Entity
data class Address(

    val id:Long=-1,
    var building:String="",
    var street:String="",
    var city:String="",

    var country:String="",
    var zipCode:String="",
    @JsonManagedReference
    @OneToOne(targetEntity = Organization::class,mappedBy = "address")
    val organization: Organization?=null
)

当我将调试点放在我的服务类中定义的行下方时

val address:Address = addressRepository.findById(organization.address.id).get()

当我将调试点放在控制器类中定义的行下方时，我得到了每个值，但 id 变量返回 id=-1

return organizationService.updateOrganization(id, organization)

我得到与上面相同的结果。这种类型的异常的原因是什么。我从不处理任何异常，默认情况下会发生异常处理。
