Jackson XML - 无法反序列化 Boolean

Question

我正在尝试使用 Jackson 解析 XML 内容，但我对 Boolean 值有一些困难。 这是我的 XML 内容的一部分：

<?xml version="1.0" encoding="UTF-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soap:Body xmlns:ns1="http://somecontent">
    <wsResponse xmlns="http://somecontent">
      <responseType>SUCCESS</responseType>
      <response>
        <successfullResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="InterchangeSearchResponse">
          <totalResult>1</totalResult>
          <returnedResults>1</returnedResults>
          <pageIndex>1</pageIndex>
          <interchanges>
            <interchange>
              <depositId>somecontent</depositId>
              <interchangeId>somecontent</interchangeId>
              <depositDate>2021-03-26T11:45:05.000+01:00</depositDate>
              <depositSubject>dépôt WS</depositSubject>
              <numADS>number</numADS>
              <adsDate>2021-03-26T11:45:05.000+01:00</adsDate>
              <alias>contentAsString</alias>
              <version xsi:nil="true"/>
              <isTest>false</isTest>
              <deposantAccount>
                <name>someString</name>
              </deposantAccount>
              <teleProcedure>someString</teleProcedure>
              <statesHistory>

这是我的 XML 结构为 class：

    @JacksonXmlProperty(localName = "Body")
    private Body body;

    public Body getBody() {
        return body;
    }

    public void setBody(Body body) {
        this.body = body;
    }
}

@JacksonXmlRootElement
public class Body {
    @JacksonXmlProperty(localName = "Fault")
    private Fault fault;
    private WsResponse wsResponse;

    public Fault getFault() {
        return fault;
    }
    public void setFault(Fault fault) {
        this.fault = fault;
    }
    public WsResponse getWsResponse() {
        return wsResponse;
    }
    public void setWsResponse(WsResponse wsResponse) {
        this.wsResponse = wsResponse;
    }
}

}

        return declarationId;
    }

    public void setDeclarationId(List<String> declarationId) {
        this.declarationId = declarationId;
    }
}

正如您在立交桥 class 中看到的那样，我尝试了一些东西，但没有任何效果。

我像这样生成我的 class ：

JacksonXmlModule xmlModule = new JacksonXmlModule();
            xmlModule.setDefaultUseWrapper(false);

            XmlMapper xmlMapper = new XmlMapper(xmlModule);
            xmlMapper.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
            xmlMapper.enable(MapperFeature.ACCEPT_CASE_INSENSITIVE_VALUES);
            System.out.println(responseAsString);
            Envelope envelope = xmlMapper.readValue(responseAsString, new TypeReference<>() {

但是当我尝试解析我的内容时，我得到了这个异常：

无法构造payload.response.Interchange的实例（尽管至少存在一个 Creator）：没有字符串参数构造函数/工厂方法可以从 [Source: (StringReader) 处的字符串值 ('false') 进行反序列化； line: 20, column: 28] （通过引用链：payload.response.Envelope["Body"]->payload.response.Body["wsResponse"]->payload.response.WsResponse["response"]->payload .response.Response["successfullResponse"]->payload.response.SuccessfulResponse["interchanges"]->payload.response.Interchanges["interchange"]->java.util.ArrayList[1])

我尝试了很多东西，但没有任何效果，所以我想知道问题是否不在这里......如果您有任何解决方案或探索的线索，请告诉我！

感谢。

根据 JavaBean 规范，您必须命名 getter isTest() 。
