Question

*解决方案在第一个答案中

我非常喜欢使用SimpleXML Converter，所以模型和注释可能是错误的。

这是我收到的XML：

<?xml version="1.0" encoding="UTF-8"?>
<cards-summary-response xmlns="http:/mywebpage.com/rest-api">
    <card-summary>
        <identifier>51641C1B23931</identifier>
        <display-name>Debit Card</display-name>
        <program-name>plastic_debit</program-name>
        <status>Blocked</status>
    </card-summary>
    <card-summary>
        <identifier>4E1BDFCC1D6</identifier>
        <display-name>Virtual Debit</display-name>
        <program-name>virtual_debit</program-name>
        <status>Active</status>
    </card-summary>
</cards-summary-response>

我的模特：

CardSummaryResponse.kt

@Root(strict = false, name = "cards-summary-response")
data class CardSummaryResponse constructor(
    @ElementList(
        required = false,
        name = "card-summary",
        entry = "card-summary",
        inline = true,
        empty = true
    )
    var cardsSummaryList: MutableList<CardSummary>? = null
)

CardSummary.kt

@Root(name = "card-summary")
data class CardSummary @JvmOverloads constructor(
    @field:Element(name = "identifier", required = true)
    var identifier: String = "",
    @field:Element(name = "status", required = true)
    var status: String = ""
)

API配置：

retrofit = Retrofit.Builder()
    .addConverterFactory(SimpleXmlConverterFactory.createNonStrict(
            Persister(AnnotationStrategy())
        )
    )
    .baseUrl(CallsConfiguration.BASE_URL_WIRECARD)
    .client(clientBuilder.build())
    .build()
service = retrofit.create(RetrofitInterface::class.java)

和RetrofitInterface（此类在Java中）：

@GET("webservices/wd-test.phtml")
Call<CardSummaryResponse> getCardsSummary();

我总是遇到相同的异常：

java.lang.Error：org.simpleframework.xml.core.ConstructorException：参数“ card-summary”在类中不匹配 com.app.account.model.CardSummaryResponse

有什么建议吗？

Answer 1

就我而言，我在数据类中使用了'val'。花了3个小时后，我找到了解决方案：只需将'val替换为'var'，然后给default value.

以下是我的数据类，它们在解决方案之后运行良好：

sealed class Feeds {

@Root(name = "rss", strict = false)
data class RssFeed constructor(@field:Element(name = "channel") var channel: RssChannel? = null) :
    Feeds()

@Root(name = "channel", strict = false)
data class RssChannel constructor(
    @field:ElementList(
        name = "item",
        inline = true,
        required = false
    ) var item: List<RssItem>? = null
) : Feeds()

@Root(name = "item", strict = false)
data class RssItem constructor(
    @field:Element(name = "title") var title: String = "",
    @field:Element(name = "description") var description: String = "",
    @field:Element(name = "link") var link: String = ""
) : Feeds()
}

快乐编码！！！

Answer 2

我设法使用以下模型使其工作：

CardSummaryResponse.tk

@Root(strict = false, name = "cards-summary-response")
data class CardSummaryResponse constructor(
    @field:ElementList(
        required = false,
        name = "card-summary",
        entry = "card-summary",
        inline = true,
        empty = true
    )
    var cardsSummaryList: MutableList<CardSummary>? = null
)

CardSummary.tk

@Root(name = "card-summary")
data class CardSummary constructor(
    @field:Element(name = "identifier", required = true)
    var identifier: String = "",
    @field:Element(name = "status", required = true)
    var status: String = ""
)

使用Retrofit和SimpleXML解析XML的ConstructorException（参数不匹配）
