Question

Xml内容

<?xml version="1.0" encoding="UTF-8"?>
<COUNTRY xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.w3schools.com Country_Details.xsd">

    <STATE name="AndhraPradesh">
        <DISTRICT name="Chittoor">
            <PHONENO>255258</PHONENO>
            <ADDRESS>bazarr Street</ADDRESS>
        </DISTRICT>
        <DISTRICT name="Kadapa">
            <PHONENO>24137457</PHONENO>
            <ADDRESS>congtres Street</ADDRESS>
        </DISTRICT>
    </STATE>
    <STATE>
        ...
    </STATE>
</COUNTRY>

这是我的国家班的 Country.java

@XmlAccessorType(XmlAccessType.FIELD)

@XmlType(name = " ", propOrder = { "state" })

@XmlRootElement(name = "COUNTRY")

public class COUNTRY {

    @XmlElement(name = "STATE", required = true)
protected List<Districts> state;

    public List<Districts> getSTATE() {
        if (state == null) {
            state = new ArrayList<Districts>();
        }
        return this.state;
    }
}

套餐信息：

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.w3schools.com",
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.kk;

主要课程

public class App {

public static void main(String[] args) throws JAXBException {

    JAXBContext context = JAXBContext.newInstance(AddressDetails.class,
        COUNTRY.class, Details.class, Districts.class, ObjectFactory.class);
    Unmarshaller um = context.createUnmarshaller();
    JAXBElement<COUNTRY> jaxb = (JAXBElement<COUNTRY>) um
        .unmarshal(new File("src//Country.xml"));
    COUNTRY value = jaxb.getValue();
    System.out.println(value);
}

我收到了这样的错误：

Exception in thread "main"
javax.xml.bind.UnmarshalException:unexpected element(uri:"", local:"COUNTRY").

不知道故障在哪里，我尝试了很多，但我无法弄清楚..

Answer 1

根据您的映射，JAXB impl期望XML文档是名称空间限定的。您可以通过以下方式之一修复它：

将命名空间限定添加到XML文档。

 <COUNTRY xmlns="http://www.w3dchools.com">

从JAXB映射中删除命名空间元数据。您已使用包级别@XmlSchema注释指定了它。
- http://blog.bdoughan.com/2010/08/jaxb-namespaces.html
使用XmlFilter将正确的命名空间信息应用于当前的XML文档。
- JAXB unmarshal with declared type does not populate the resulting object with data

javax.xml.bind.UnmarshalException：意外元素（uri：“”，local：“COUNTRY”）预期元素是＆lt; {http://www.w3schools.com} COUNTRY＆gt;
