在Jaxb编组地图的问题

问题描述

我有一个包含人类地图的世界类。如果我编组课堂世界，我得到以下输出：

I have a class world that contains a map of humans. If I marshal the class world I get following output:

<world>
    <humans>
        <human key="2">
            <value>
                <name>Tom</name>
            </value>
        </human>
        <human key="1">
            <value>
                <name>Max</name>
            </value>
        </human>
    </humans>
</world>

但是我不想显示值-Tag。它应该看起来像：

But I dont want to display the "value"-Tag. It should look like:

<world>
    <humans>
        <human key="2">
            <name>Tom</name>
        </human>
        <human key="1">
            <name>Max</name>
        </human>
    </humans>
</world>

这是可能吗？

类世界和人类的代码：

@XmlRootElement
public class Human {

    @XmlElement
    private String name;

    public Human(){}
}

@XmlRootElement
public class World {

    private Map<String, Human> humans = new HashMap<String, Human>();

    public World(){}

    @XmlElementWrapper( name = "humans")
    @XmlElement(name = "human")
    public HumanEntry[] getMap() {
        List<HumanEntry> list = new ArrayList<HumanEntry>();
        for (Entry<String, Human> entry : humans.entrySet()) {
            HumanEntry mapEntry =new HumanEntry();
            mapEntry.key = entry.getKey();
            mapEntry.value = entry.getValue();
            list.add(mapEntry);
        }
        return list.toArray(new HumanEntry[list.size()]);
    }

    public void setMap(HumanEntry[] arr) {
        for(HumanEntry entry : arr) {
            this.humans.put(entry.key, entry.value);
        }
    }

    public static class HumanEntry {
        @XmlAttribute
        public String key;

        @XmlElement
        public Human value;
    }

    public void addHuman(String key, Human human){
        this.humans.put(key, human);
    }
}

推荐答案

被指出， XmlAdapter 可用于应用替代映射到JAXB中的Map（或任何类型）。以下是一个具体示例的链接：

As was pointed out by ilcavero an XmlAdapter can be used to apply an alternative mapping to Map (or any type) in JAXB. Below is a link to a concrete example:
