代码

        ...
        SOAPMessage sm = response;
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        sm.writeTo(out);

        this.results = (SearchFlightsResponse) JAXB.unmarshal(sm.toString(), SearchFlightsResponse.class);

Answer 1

您从 SOAP 服务收到的 XML 响应不是有效的 XML。 xmlns 属性必须是绝对的 URI .

这意味着命名空间名称必须采用以下形式:<scheme>:<scheme-specific-part>

为了使 XML 有效，您调用的服务应该发回 urn:ElsyArres.API作为命名空间值。

<SearchFlightsResponse xmlns="urn:ElsyArres.API">

您的包信息文件将如下所示:

@XmlSchema( 
    namespace = "urn:ElsyArres.API", 
    elementFormDefault = XmlNsForm.QUALIFIED) 
package com.myProject.wegolo

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

如果您无法获得修复 URI 问题的服务，您可以在通过使用 SAXFilter 解码时将其删除。这是一个很好的例子，它支持在解码期间添加和删除 namespace :https://stackoverflow.com/a/2148541/73446
