android - 无法使用 Retrofit 2 和简单 XML 转换器获取 SOAP 信封正文

Question

我正在使用 Retrofit 2.2.0 和 Retrofit SimpleXML Converter 2.2.0。我使用 addConverterFactory 方法将 SimpleXmlConverter 添加到 Retrofit 实例。

问题是当我收到响应时，出现以下错误

java.lang.RuntimeException: org.simpleframework.xml.core.ElementException: Element 'Body' does not have a match in class ResponseEnvelope at line 1

我应该得到这样的 XML 响应:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <ns:autenticarUsuarioPorEmailResponse xmlns:ns="http://business.curitiba.org.br">
         <ns:return xsi:type="ax2471:AutenticaUsuarioPorEmailSaida" xmlns:ax2471="http://saidas.curitiba.org/xsd" xmlns:ax2469="http://entities.curitiba.org/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ax2467="http://entradas.curitiba.org/xsd">
            <ax2471:idCredencial>3282</ax2471:idCredencial>
            <ax2471:tokenAcesso>635E3DA9-7C02-4DB7-9653-E7688C66B02C</ax2471:tokenAcesso>
         </ns:return>
      </ns:autenticarUsuarioPorEmailResponse>
   </soapenv:Body>
</soapenv:Envelope>

响应信封.java

@Root(name = "soapenv:Envelope")
@Namespace(prefix = "soapenv", reference = "http://schemas.xmlsoap.org/soap/envelope/")
public class ResponseEnvelope {

    @Element(name = "soapenv:Body", required = false)
    private ResponseBody body;

    public ResponseBody getBody() {
        return body;
    }

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

响应体.java

@Root(name = "soapenv:Body", strict = false)
public class ResponseBody {

    @Element(name = "ns:cadastrarCredencialEmailResponse", required = false)
    private ResponseData requestData;

    public ResponseData getRequestData() {
        return requestData;
    }

    public void setRequestData(ResponseData requestData) {
        this.requestData = requestData;
    }

}

响应数据.java

@Root(name = "ns:cadastrarCredencialEmailResponse", strict = false)
@Namespace(prefix = "ns", reference = "http://business.curitiba.org")
public class ResponseData {

    @Element(name = "ns:return", required = false)
    private ResponseInfo info;

    public ResponseInfo getInfo() {
        return info;
    }

    public void setInfo(ResponseInfo info) {
        this.info = info;
    }
}

响应信息.java

@Root(name = "ns:return", strict = false)
@NamespaceList({
        @Namespace(prefix = "ax2471", reference = "http://saidas.curitiba.org/xsd"),
        @Namespace(prefix = "ax2469", reference = "http://entities.curitiba.org/xsd"),
        @Namespace(prefix = "xsi", reference = "http://www.w3.org/2001/XMLSchema-instance"),
        @Namespace(prefix = "ax2467", reference = "http://entradas.curitiba.org/xsd")
})
public class ResponseInfo {

    @Element(name = "ax2471:codigoAtivacao", required = false)
    private String codigoAtivacao;
    @Element(name = "ax2471:idCredencial", required = false)
    private String idCredencial;

    public String getCodigoAtivacao() {
        return codigoAtivacao;
    }

    public void setCodigoAtivacao(String codigoAtivacao) {
        this.codigoAtivacao = codigoAtivacao;
    }

    public String getIdCredencial() {
        return idCredencial;
    }

    public void setIdCredencial(String idCredencial) {
        this.idCredencial = idCredencial;
    }
}

我想问题出在 ResponseInfo 类中，我不知道如何将属性 xsi:type 放入其中。谁能帮帮我？

Answer 1

我不知道简单 XML 转换器的具体工作原理，但元素名称就是元素名称，它们可以前缀。这似乎是混淆，因为 : 字符用于分隔物理 XML 文档(标签)中的 namespace 前缀和元素名称。

您可以只从名称中删除“前缀”并添加 @Namespace 注释。例如:

响应信封.java

@Root(name = "Envelope")
@Namespace(prefix = "soapenv", reference = "http://schemas.xmlsoap.org/soap/envelope/")
final class ResponseEnvelope {

    @Element(name = "Body", required = false)
    @Namespace(prefix = "soapenv", reference = "http://schemas.xmlsoap.org/soap/envelope/")
    final ResponseBody body;

    private ResponseEnvelope(
            @Element(name = "Body") final ResponseBody body
    ) {
        this.body = body;
    }

}

响应体.java

@Root(name = "Body", strict = false)
@Namespace(prefix = "soapenv", reference = "http://schemas.xmlsoap.org/soap/envelope/")
final class ResponseBody {

    @Element(name = "autenticarUsuarioPorEmailResponse", required = false)
    @Namespace(prefix = "ns", reference = "http://business.curitiba.org")
    final ResponseData requestData;

    private ResponseBody(
            @Element(name = "autenticarUsuarioPorEmailResponse") final ResponseData requestData
    ) {
        this.requestData = requestData;
    }

}

响应数据.java

@Root(name = "autenticarUsuarioPorEmailResponse", strict = false)
@Namespace(prefix = "ns", reference = "http://business.curitiba.org")
final class ResponseData {

    @Element(name = "return", required = false)
    @Namespace(prefix = "ns", reference = "http://business.curitiba.org")
    final ResponseInfo info;

    private ResponseData(
            @Element(name = "return") final ResponseInfo info
    ) {
        this.info = info;
    }

}

响应信息.java

@Root(name = "return", strict = false)
@Namespace(prefix = "ns", reference = "http://business.curitiba.org")
final class ResponseInfo {

    @Element(name = "tokenAcesso", required = false)
    @Namespace(prefix = "ax2471", reference = "http://saidas.curitiba.org/xsd")
    final String accessToken;

    @Element(name = "idCredencial", required = false)
    @Namespace(prefix = "ax2471", reference = "http://saidas.curitiba.org/xsd")
    final String credentialId;

    private ResponseInfo(
            @Element(name = "tokenAcesso") final String accessToken,
            @Element(name = "idCredencial") final String credentialId
    ) {
        this.accessToken = accessToken;
        this.credentialId = credentialId;
    }

}

所以下面的例子:

final ResponseInfo info = responseEnvelope.body.requestData.info;
System.out.println(info.accessToken);
System.out.println(info.credentialId);

将输出:
