实体的 Spring Boot JPA 投影，Postgresql JSON 字段为 Map<Key, Value>

如何解决实体的 Spring Boot JPA 投影，Postgresql JSON 字段为 Map<Key, Value>

我使用带有 Kotlin 和 Postgresql 作为数据库的 Spring Boot。对于 JSON 字段，我使用 hibernate-types-52:

dependencies {
    ...
    implementation("com.vladmihalcea:hibernate-types-52:2.10.2")
    ...
}

我有一个带有街道 JSON 字段的实体地址：

@Entity
@Table(name = "addresses")
@TypeDefs(
  TypeDef(name = "jsonb",typeClass = JsonBinaryType::class),TypeDef(name = "json",typeClass = JsonStringType::class),)
data class Address(

  @Id
  var id: Int? = null,@Type(type = "jsonb")
  @Column(name = "street",columnDeFinition = "json",nullable = false)
  var street: Map<Language,String>,@Column(name = "zip_code" nullable = false)
  var zipCode: String,@Column(name = "created_at",nullable = false,updatable = false)
  @CreationTimestamp
  var createdAt: Date? = null,@Column(name = "updated_at",nullable = false)
  @UpdateTimestamp
  var updatedAt: Date? = null,}

对应的仓库是：

@Repository
interface AddressRepository : JpaRepository<Address,Int> {

    fun findStreetByZipCode(zipCode: String): Addressstreetonly?
}

其中 Addressstreetonly 是一个接口：

interface Addressstreetonly {
    val id: Int
    val street: Map<Language,String>
}

和 Language 是一个枚举 enum class Language { EN,RU,KZ,TJ }

问题是当我调用 findStreetByZipCode 时，底层 sql 语句在选择查询中具有所有字段：

select
    address0_.id as id1_9_,address0_.created_at as created_2_9_,address0_.street as street3_9_,address0_.updated_at as updated4_9_,address0_.zip_code as zip_cod5_9_
from
    addresses
where
    address0_.zip_code = ?

但如果我将 Addressstreetonly 接口中的 val street: Map<Language,String> 类型更改为 val street: Any，一切都会按预期进行：

select
    address0_.id as col_0_0_,address0_.street as col_1_0_
from
    addresses
where
    address0_.zip_code = ?

我认为问题出在街道字段的类型上，即 Map 并且 Map 强制获取实体的所有字段。我该如何解决这个问题？
