无法将xml转换为java.How，无法使用retrofit2将xml转换为java

Question

嗨，我正在尝试使用rest来编写一个简单的REST客户机，我试图调用一个REST，它返回一个xml响应，但是REST不能解析xml。

改造代码

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(API_URL)
                .addConverterFactory(SimpleXmlConverterFactory.create())
                .build();
        // Create an instance of our OfferClient API interface.
        OfferClient offerClient = retrofit.create(OfferClient.class);

        // Create a call instance for looking up offers.
        String offerID="20000798";
        Call<Offer> call = offerClient.offers(offerID);
        Offer offer = call.execute().body();
        System.out.println("Offer Response..."+ offer.getDescription());

线程"main“中的异常: org.simpleframework.xml.core.ElementException:元素'featureSetID‘在retrofit2.converter.simplexml.SimpleXmlResponseBodyConverter.convert(SimpleXmlResponseBodyConverter.java:44)的第1行的com.intuit.schema.platform.webs.catalog.internal.offers.v3.Offer$Product类中没有匹配。

无法排除的反应。

Answer 1

在您的改造构建器中将addConverterFactory(SimpleXmlConverterFactory.create())替换为addConverterFactory(SimpleXmlConverterFactory.createNonStrict())。这将使解析器能够容忍在POJO中没有出现的xml标记。
