使用带字符的JAXB

Question

我有一个类型为Character的@XMLElement但是当它被编组时,它似乎被放入二进制字符串中,例如......

'n' becomes 110
'e' becomes 101

没有将它们转换为字符串是否有一种方法可以输出文本字符而不是表示？

Answer 1

你可以写一个XmlAdapter.An XmlAdapter允许您将一种类型的对象转换为另一种类型,以便进行编组/解组.

XmlAdapter(CharacterAdapter)

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

public class CharacterAdapter extends XmlAdapter<String, Character> {

    @Override
    public Character unmarshal(String v) throws Exception {
        return v.charAt(0);
    }

    @Override
    public String marshal(Character v) throws Exception {
        return new String(new char[] {v});
    }

}

Java模型

在XmlAdapter使用指定的@XmlJavaTypeAdapter注释:

import javax.xml.bind.annotation.*;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

@XmlRootElement
public class Foo {

    private Character bar;

    @XmlJavaTypeAdapter(CharacterAdapter.class)
    public Character getBar() {
        return bar;
    }

    public void setBar(Character bar) {
        this.bar = bar;
    }

}
