我一直在尝试从类型Customer类对象的列表中生成 XML 文件。我已经成功完成了。但是我的 XML 文件的结构是嵌套的，我想将其展平。

以下是我的 XML 文件内容：

<Customers>
<customer>

    <taxable>false</taxable>
    <unbilledOrders>76.8</unbilledOrders>
    <webLead>No</webLead>
</customer>
</Customers>

所以我有嵌套结构<accessRole>，我想像这样展平 <accessRole-name>，我不想像<internalId>.

请找到我的模型的代码片段：

try {
             FileWriter fileWriter = new FileWriter ("D:\\adapter-framework\\Customer_XML.xml");
             JAXBContext jaxbContext = JAXBContext.newInstance(extractedRecordsArray[0].getClass());
             Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
             fileWriter.append("<Customers>");
             fileWriter.append('\n');
             for(int i = 0; i < extractedRecordsArray.length - 761 ; i++)
             {          
                jaxbMarshaller.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE);
                jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
                //jaxbMarshaller.marshal(extractedRecordsArray[i],fileWriter);
                jaxbMarshaller.marshal(extractedRecordsArray[i],System.out);
                fileWriter.append('\n');
                AdapterLogger.debug(this.getClass().getName(), "Extracted record number : " + i);
             }        
            fileWriter.append("</Customers>");
            fileWriter.close();
          } catch (JAXBException e) {
            e.printStackTrace();
           }

如果有人知道，请帮助我。

谢谢。

注意： 我是EclipseLink JAXB (MOXy)负责人，也是JAXB (JSR-222)专家组的成员。

您可以使用@XmlPathMOXy 中的扩展来扁平化 XML 结构。

顾客

import javax.xml.bind.annotation.*;
import org.eclipse.persistence.oxm.annotations.XmlPath;

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Customer {

    @XmlPath(".")
    private AccessRole accessRole;

}

访问角色

import javax.xml.bind.annotation.*;

@XmlAccessorType(XmlAccessType.FIELD)
public class AccessRole {

    @XmlElement(name="accessRoleName")
    private String name;

}
