java - 如何从生成的 JAXB 中删除命名空间

Question

使用JAVA 7，XJC。

xsd 由使用 .NET 的第三方提供。

当前的问题是，当我将对象编码到 XML 中时，我得到了以下内容:

<SalesOrder xmlns:ns2="http://schemas.datacontract.org/2004/07/RKLServiceQueue">
  <ns2:BillToAddrLine1>7315 N Ritter Ave</ns2:BillToAddrLine1>
  <ns2:BillToAddrLine2></ns2:BillToAddrLine2>
  <ns2:BillToAddrName>David Kruse</ns2:BillToAddrName>
  <ns2:BillToCity>Indianapolis</ns2:BillToCity>
  <ns2:BillToCountryID>USA</ns2:BillToCountryID>
  <ns2:BillToPostalCode>46250</ns2:BillToPostalCode>
</SalesOrder

该服务期待这样的事情:

  <SalesOrder xmlns="http://schemas.datacontract.org/2004/07/RKLServiceQueue">
    <BillToAddrLine1>String content</BillToAddrLine1>
    BillToAddrLine2>String content</BillToAddrLine2>
    <BillToAddrLine3>String content</BillToAddrLine3>
    <BillToAddrLine4>String content</BillToAddrLine4>
    <BillToAddrLine5>String content</BillToAddrLine5>
    <BillToAddrName>String content</BillToAddrName>
    <BillToCity>String content</BillToCity>
  </SalesOrder>

这也是 xsd 的一部分

<xs:schema xmlns:tns="http://schemas.datacontract.org/2004/07/RKLServiceQueue" elementFormDefault="qualified" targetNamespace="http://schemas.datacontract.org/2004/07/RKLServiceQueue" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:complexType name="SalesOrder">
    <xs:sequence>
      <xs:element minOccurs="0" name="BillToAddrLine1" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToAddrLine2" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToAddrLine3" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToAddrLine4" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToAddrLine5" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToAddrName" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToCity" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToCountryID" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToPostalCode" nillable="true" type="xs:string" />
      <xs:element minOccurs="0" name="BillToStateID" nillable="true" type="xs:string" />

我在SoapUI上进行了测试来验证。

我在网上进行了一些搜索，包括 stackoverflow，它指出使用 NamespacePrefixMapper 但这似乎并不能解决问题。我不断收到以下异常:

javax.xml.bind.PropertyException: name: com.sun.xml.internal.bind.marshaller.namespacePrefixMapper value: com.heritage.jobs.MyPrefixMapper@29545330 

这是映射器

import com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper;


/**
 * 
 */
public class MyPrefixMapper extends NamespacePrefixMapper
{
    private static final String FOO_PREFIX = ""; // DEFAULT NAMESPACE
    private static final String FOO_URI = "http://schemas.datacontract.org/2004/07/RKLServiceQueue";


    /*
     * (non-Javadoc)
     * 
     * @see com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper#getPreferredPrefix(java.lang.String,
     * java.lang.String, boolean)
     */
    @Override
    public String getPreferredPrefix(final String pNameSpaceUri, final String pSuggestion, final boolean pRequirePrefix)
    {
        if (FOO_URI.equals(pNameSpaceUri))
        {
            return FOO_PREFIX;
        }

        return pSuggestion;
    }

这是我用来调用它的:

final JAXBContext context = JAXBContext.newInstance(SalesOrder.class);

marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");

final MyPrefixMapper prefixMapper = new MyPrefixMapper();
try
{
        marshaller.setProperty("com.sun.xml.internal.bind.marshaller.namespacePrefixMapper", prefixMapper);
}
catch (final PropertyException e)
{
LOG.error("perform(CronJobModel)", e);
}

我不清楚我缺少什么来完成这项工作 - 如何从每个字段/属性中删除命名空间 ns？

Answer 1

尝试像这样使用 package-info.java 中的注释:

@javax.xml.bind.annotation.XmlSchema(namespace = "http://myOutput", xmlns = {@XmlNs(prefix = "", namespaceURI = "http://myOutput")}, elementFormDefault = XmlNsForm.QUALIFIED)

这样我就摆脱了根元素上的 ns2...
