JAXB解组要映射的未定义元素？

Question

我有要[[unmarshall的XML：]]

<?xml version="1.0" encoding="UTF-8"?>
<ROW id='1'>
   <MOBILE>9831138683</MOBILE>
   <A>1</A>
   <B>2</B>
</ROW>

我想将其映射到
class

：

import java.util.*;
import javax.xml.bind.annotation.*;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
import org.eclipse.persistence.oxm.annotations.XmlPath;

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

    @XmlPath(".")
    @XmlJavaTypeAdapter(MapAdapter.class)
    private Map<String, Integer> map = new HashMap<String, Integer>();

    @XmlAttribute
    private int id;
    @XmlElement(name = "MOBILE")
    private int mobileNo;

}

为此，我尝试使用bdoughan的@XmlVariableNode("key")博客：

MapAdapter：

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

import javax.xml.bind.annotation.XmlTransient;
import javax.xml.bind.annotation.XmlValue;
import javax.xml.bind.annotation.adapters.XmlAdapter;

import org.eclipse.persistence.oxm.annotations.XmlVariableNode;

public class MapAdapter extends XmlAdapter<MapAdapter.AdaptedMap, Map<String, String>> {

    public static class AdaptedMap {

        @XmlVariableNode("key")
        List<AdaptedEntry> entries = new ArrayList<AdaptedEntry>();

    }

    public static class AdaptedEntry {

        @XmlTransient
        public String key;

        @XmlValue
        public String value;

    }

    @Override
    public AdaptedMap marshal(Map<String, String> map) throws Exception {
        AdaptedMap adaptedMap = new AdaptedMap();
        for(Entry<String, String> entry : map.entrySet()) {
            AdaptedEntry adaptedEntry = new AdaptedEntry();
            adaptedEntry.key = entry.getKey();
            adaptedEntry.value = entry.getValue();
            adaptedMap.entries.add(adaptedEntry);
        }
        return adaptedMap;
    }

    @Override
    public Map<String, String> unmarshal(AdaptedMap adaptedMap) throws Exception {
        List<AdaptedEntry> adaptedEntries = adaptedMap.entries;
        Map<String, String> map = new HashMap<String, String>(adaptedEntries.size());
        for(AdaptedEntry adaptedEntry : adaptedEntries) {
            map.put(adaptedEntry.key, adaptedEntry.value);
        }
        return map;
    }

}

使用这种方法，所有键（MOBILE, id, A, B）都映射到Map内部。我想将所有已定义的属性id，MOBILE映射到其在POJO中的属性，其余所有属性都映射到Map。
如何实现？

我有一个要解组的XML：

9831138683

我为您提供了一个解决方案，但与您上面的尝试略有不同。

让我们学习根类：
