Kotlin modelMapper, Int to Float

Question

我使用 kotlin/springboot，我想使用 ModelMapper 映射到数据类。我想将Account:balance:Amount:Int 映射到AccountDto:balance:Float

发件人：

data class Account(
        val id: String,
        var balance: Amount
)

data class Amount(var value: Int)

收件人：

data class AccountDto(
        var id: String,
        var balance: Float?)

我试过这个：

val modelMapper = ModelMapper()

modelMapper.addMappings(object : PropertyMap<Account, AccountDto>() {
    override fun configure() {
        map(source.balance.value / 100f, destination.balance)
    }
})

但我有这样的错误：

Caused by: org.modelmapper.ConfigurationException: ModelMapper configuration errors:

1) Cannot map final type ....accounts.Account.

2) Cannot map final method ....accounts.Account.getBalance().

3) Cannot map final type ....accounts.Amount.

4) Cannot map final method ....accounts.Amount.getValue().

5) Cannot map final type ....account.dto.AccountDto.

6) Cannot map final method ....account.dto.AccountDto.getBalance().

我现在没有更多的想法。

Answer 1

将val 更改为var

data class Account(
        val id: String,
        var balance: Amount
)
