jaxb解組xml元素以包含一些字段

Question

我有一些課：

class Location  {   

    private Long id;   

    private String roomTitle;  

    protected Specialization specialization;
}

public class Specialization  {

    private Long id;

    private boolean archived;

    private String title;
}

和xml：

<location id="10"> 
  <roomTitle>string</roomTitle>
  <specializationId>10</specializationId>
</location>

我可以將specializationId解組為Location.specialization.id嗎？

Answer 1

我不了解jaxb，但SimpleXml可以做到。

首先，我們需要添加一些注釋：

public class Location  {
    private Long id;
    private String roomTitle;
    @XmlName("specializationId")
    protected Specialization specialization;
}

public class Specialization  {
    @XmlTextNode
    private Long id;
    private Boolean archived;
    private String title;
}

注意， archived現在是一個布爾類。 常規布爾值不能為null。 接下來，我們將xml序列化為Location類。

final SimpleXml simple = new SimpleXml();
final Location l = simple.fromXml(xml, Location.class);

然后我們可以打印值

System.out.println(l.specialization.id);

這將打印
