JAXB：如何将映射编组到 keyvaluekey

JAXB：如何将映射编组到 value

java
public class KeyValue {
    private String key;
    private String value;
    // 省略构造函数、getter和setter方法
    @XmlElement(name = "key")
    public String getKey() {
        return key;
    }
    public void setKey(String key) {
        this.key = key;
    }
    @XmlElement(name = "value")
    public String getValue() {
        return value;
    }
    public void setValue(String value) {
        this.value = value;
    }
}

java
@XmlRootElement(name = "mapping")
public class Mapping {
    private List keyValueList;
    // 省略构造函数和getter/setter方法
    @XmlElement(name = "entry")
    public List getKeyValueList() {
        return keyValueList;
    }
    public void setKeyValueList(List keyValueList) {
        this.keyValueList = keyValueList;
    }
}

java
public class JAXBExample {
    public static void main(String[] args) throws JAXBException {
        List keyValueList = new ArrayList<>();
        keyValueList.add(new KeyValue("key1", "value1"));
        keyValueList.add(new KeyValue("key2", "value2"));
        keyValueList.add(new KeyValue("key3", "value3"));
        Mapping mapping = new Mapping();
        mapping.setKeyValueList(keyValueList);
        JAXBContext jaxbContext = JAXBContext.newInstance(Mapping.class);
        Marshaller marshaller = jaxbContext.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(mapping, System.out);
    }
}

xml
  
    key1
    value1
  
  
    key2
    value2
  
  
    key3
    value3
