Question

@XmlRootElement(name="ItemSearchResponse")
public class AmazonItem
{
    private String name;
    private String asin;
    private String price;

    public AmazonItem()
    {

    }

    @XmlJavaTypeAdapter(CollapsedStringAdapter.class)
    @XmlElement(name="Title")
    public String getName()
    {
        return name;
    }
    public void setName(String name)
    {
        this.name = name;
    }

    @XmlJavaTypeAdapter(CollapsedStringAdapter.class)
    @XmlElement(name="ASIN")
    public String getAsin()
    {
        return asin;
    }
    public void setAsin(String asin)
    {
        this.asin = asin;
    }

    @XmlJavaTypeAdapter(CollapsedStringAdapter.class)
    @XmlElement(name="FormattedPrice")
    public String getPrice()
    {
        return price;
    }
    public void setPrice(String price)
    {
        this.price = price;
    }
}

public class AmazonItemBuilder
{
    public AmazonItemBuilder()
    {

    }

    public List<AmazonItem> build(InputStream response)
    {
        try
        {
            JAXBContext context = JAXBContext.newInstance(AmazonItem.class);
            Unmarshaller unMarshaller = context.createUnmarshaller();
            AmazonItem newItem = (AmazonItem) unMarshaller.unmarshal(response);
            System.out.println(newItem);
        }
        catch (JAXBException e)
        {
            e.printStackTrace();
        }
        return null;
    }
}

好的，我忘记了错误-_-javax.xml.bind.UnMarshalException：意外元素（URI：“http://webservices.amazon.com/awsecommerceservice/2011-08-01”，本地：“ItemSearchResponse”）。所需元素为<{}ItemSearchResponse>

谢谢你！

XML文档似乎是命名空间限定的。您可以使用包级别的@xmlschema位置批注为整个文档指定命名空间限定。包级批注通过名为package-info的特殊调用进行，该调用如下所示：

包-信息

@XmlSchema(
    namespace = "http://webservices.amazon.com/AWSECommerceService/2011-08-01",
    elementFormDefault = XmlNsForm.QUALIFIED)
package com.your.pkg;

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
