java - 如何在java spring-boot上将xml转换为对象

Question

你好，我正在尝试用对象数量转换 xml，我得到一个 错误消息:文档中跟在根元素之后的标记必须格式正确。

XML:

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="test.example.com">
  <Item>
    <ItemKey>1111</ItemKey>
    <Start>2/10/2017</Start>
    <customNumber>12</customNumber>
    <End>2/10/2018</End>
    <Account>2221111</Account>
    <Name>John</Name>
    <Note>GOOD</Note>
    <CodeNo>4444-1</CodeNo>
    <Source>www.cnn.com</Source>
  </Item>
  <Item>
    <ItemKey>2222</ItemKey>
    <Start>2/10/2017</Start>
    <customNumber>75</customNumber>
    <End>2/10/2018</End>
    <Account>3333111</Account>
    <Name>Smith</Name>
    <Note>NOT GOOD</Note>
    <CodeNo>4444-2</CodeNo>
    <Source>www.fox.com</Source>
  </Item>
</string>

模型类:

package example.models;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "Item")
public class Model {

private String CodeNo;

private String ItemKey;

private String Start;

private String End;

private String Account;

private String Name;

private String Note;

...(gets and sets)

主要代码:

StringReader reader = new StringReader(response);
String response = restTemplate.getForObject(url, String.class);
...

 JAXBContext jaxbContext = JAXBContext.newInstance(Model.class);
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
            Model recordes = (Model) unmarshaller.unmarshal(reader);

解码异常: 文档中跟在根元素之后的标记必须格式正确。

xml 只有一项代码有效。

我缺少什么并且需要做什么才能无误地获取元素(项目)对象列表？

在 XML 文件中，您的根元素是 <string xmlns="test.example.com">标记，以便更正 XML 或更正 Model 类以使其正常工作。

编辑

您可以使用此工具生成 POJO:http://pojo.sodhanalibrary.com

下面是上述 XML 的 POJO 类:

public class MyXML
{
    private String string; // Change the class as String is Wrapper class

    public String getString ()
    {
        return string;
    }

    public void setString (String string)
    {
        this.string = string;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [string = "+string+"]";
    }
}

字符串类:

public class String // Change this className as String is Wrapper class in java
{
    private Item[] Item;

    private String xmlns;

    public Item[] getItem ()
    {
        return Item;
    }

    public void setItem (Item[] Item)
    {
        this.Item = Item;
    }

    public String getXmlns ()
    {
        return xmlns;
    }

    public void setXmlns (String xmlns)
    {
        this.xmlns = xmlns;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [Item = "+Item+", xmlns = "+xmlns+"]";
    }
}

public class Item
{
    private String Name;

    private String Source;

    private String End;

    private String CodeNo;

    private String Start;

    private String Account;

    private String ItemKey;

    private String Note;

    private String customNumber;

    public String getName ()
    {
        return Name;

    public void setName (String Name)

        this.Name = Name;
    }

    public String getSource ()

        return Source;
    }

    public void setSource (String Source)

        this.Source = Source;
    }

    public String getEnd ()
    {
        return End;
    }

    public void setEnd (String End)
    {
        this.End = End;
    }

    public String getCodeNo ()
    {
        return CodeNo;
    }

    public void setCodeNo (String CodeNo)
    {
        this.CodeNo = CodeNo;
    }

    public String getStart ()
    {
        return Start;
    }

    public void setStart (String Start)
    {
        this.Start = Start;
    }

    public String getAccount ()
    {
        return Account;
    }

    public void setAccount (String Account)
    {
        this.Account = Account;
    }

    public String getItemKey ()
    {
        return ItemKey;
    }

    public void setItemKey (String ItemKey)
    {
        this.ItemKey = ItemKey;
    }

    public String getNote ()
    {
        return Note;
    }

    public void setNote (String Note)
    {
        this.Note = Note;
    }

    public String getCustomNumber ()
    {
        return customNumber;
    }

    public void setCustomNumber (String customNumber)
    {
        this.customNumber = customNumber;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [Name = "+Name+", Source = "+Source+", End = "+End+", CodeNo = "+CodeNo+", Start = "+Start+", Account = "+Account+", ItemKey = "+ItemKey+", Note = "+Note+", customNumber = "+customNumber+"]";
    }
