Java JAXB复杂子XmlRootElement

我需要使用JAXB的以下格式输出

<?xml version="1.0" encoding="UTF-8"?>
<tata-sky>
    <change-package-request>
        <sub-no>1064781105</sub-no>
        <ivr-id>ubona_7301341344310891411101430133</ivr-id>
        <date-time>05/29/2013 00:16:13</date-time>
        <package-list>
            <package-ref>Punjabi Regional Free Pack</package-ref>
            <action-code>Delete</action-code>
        </package-list>
    </change-package-request>
</tata-sky>

主要方法：ChangePackageService.java

package com.tsg.flow;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

/** 
 *
 * @author Shafiq
 */
public class ChangePackageService {

    public static void main(String... args) {
        // public String createXMLString() {
        ChangePackage objCP = new ChangePackage();
        ChangepackageRequest cr = new ChangepackageRequest();

        cr.setSub_no("1064781105");
        cr.setIvr_id("ubona_7301341344310891411101430133");
        cr.setDate_time("05/29/2013 00:16:13");
        PackageRef pl = new PackageRef();
        pl.setPackage_ref("Punjabi Regional Free Pack");
        pl.setAction_code("Delete");
        objCP.setPackageList(pl);
        objCP.setChangePReq(cr);


        // create JAXB context and instantiate marshaller
        JAXBContext context = null;
        Marshaller m = null;
        try {
            context = JAXBContext.newInstance(ChangePackage.class);
            m = context.createMarshaller();
            m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
            // Write to System.out
            //m.marshal(cs, System.out);
            // Write to File
            m.marshal(objCP, System.out);
        } catch (JAXBException ex) {
            System.out.println("Error XML Generation" + ex.getMessage());
            // System.out.println("Exception Occured during marshalling: " + ex.getMessage());

        }

        //  return "";
        //  }
    }
}

请大家尽早回复解决方案。谢谢

看起来您已经注释掉了

ChangepackageRequest

中的部分代码，该代码告诉JAXB，

包列表

是

更改包请求

的子项

@XmlElement(name = "package-ref")
public PackageList getPackageList() {`

你需要做的是

• 取消对该代码的注释
• 更新它以使用

  PackageRef

  类而不是

  PackageList

• 从

  ChangePackage

---

我找到了解决方案
在ChangePakageRequest.java中

"added @XmlType(propOrder = {""}))"

所以

@XmlType（proporter={”、“日期时间”、“ivr\U id”、“子编号”}）

---

因此，它假设package ref是change package request的子元素。
您希望

package ref

元素是

change package request

的子元素，那么

PackageRef

不应该是

ChangepackageRequest

类的属性吗？您正在

ChangePackage

实例上设置它……这听起来并不是解决此问题的正确方法。将

ChangeRequest

中的

PackageRef

字段改为

ChangeRequest

是一个更好的解决方案！
