所有子元素都使用名稱空間進行標記[Spring Batch＆JAXB]

我想使用Spring Batch（JAXB2Marshaller）生成XML文件，但是我提前在此感謝下面的問題1周。所有子元素都使用名稱空間進行標記[Spring Batch＆JAXB]

預期的XML

<?xml version="1.0" encoding="UTF-8"?> 
<p:ContactList xmlns:p="test:ns:2012"> 
    <p:CompanyInfo> 
    <p:CompanyName>Oracle</p:CompanyName> 
    <p:DepartmentInfo> 
     <p:DepartmentName>Java</p:DepartmentName> 
    </p:DepartmentInfo> 
    </p:CompanyInfo> 
</p:ContactList>

但我得到

<?xml version="1.0" encoding="UTF-8"?> 
<ContactList> 
    <p:CompanyInfo xmlns:p="test:ns:2012"> 
    <p:CompanyName xmlns:p="test:ns:2012">Oracle</p:CompanyName> 
    <p:DepartmentInfo xmlns:p="test:ns:2012"> 
     <p:DepartmentName xmlns:p="test:ns:2012">Java</p:DepartmentName> 
    </p:DepartmentInfo> 
    </p:CompanyInfo> 
</ContactList>

下面是源代碼

Spring配置

<bean id="itemWriter" class="org.springframework.batch.item.xml.StaxEventItemWriter"> 
    <property name="resource" ref="outputResource" /> 
    <property name="marshaller" ref="myMarshaller" /> 
    <property name="rootTagName" value="ContactList" /> 
    <property name="overwriteOutput" value="true" /> 
</bean> 

<bean id="myMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> 
    <property name="contextPaths"> 
     <list> 
      <value>org.springframework.batch.contactlist</value> 
     </list> 
    </property> 
    <property name="marshallerProperties"> 
     <map> 
      <entry key="jaxb.formatted.output"><value type="boolean">true</value></entry> 
     </map> 
    </property> 
     <property name="supportJaxbElementClass" value="true"/> 
</bean>

XSD

     return new JAXBElement<CompanyInfo>(null, CompanyInfo.class, null, value);

CompanyInfo.java

DepartmentInfo.java

public class DepartmentInfo { 

    @XmlElement(name = "DepartmentName", required = true) 
    protected String departmentName; 
}

哪裏'加入getContextualNamespaceDecls（）解析<屬性名= 「rootTagName」值= 「ContactList」/>'進入應用程序中的發揮？有沒有機會導致根元素失去命名空間的限定，而創建一個沒有命名空間的'JAXBElement'？ –

非常感謝，新年快樂。「rootTagName」是org.springframework.batch.item.xml.StaxEventItemWriter的一個屬性，它將在startDocument（）方法中寫入根元素，writer.add（factory.createStartElement（「」，「」，getRootTagName（））） ;我沒有在我的應用程序中添加任何JAXBElement，除了在ObjectFactory中，返回新的JAXBElement （新的QName（「p」，「test-ns-2012」），CompanyInfo.class，null，value）; – Weber

問題在NamespacePrefixMapper

@Override 
public String[] getContextualNamespaceDecls() { 
    return new String[] {"p", "test-ns-2012" }; 
}
