Question

我有一个具有集合元素的Object。我确信它在集合中具有价值。当对象值被解组时，我在XML输出中没有得到任何单个值。你认为我命名我的包装器对象的方式不正确吗？

这是我的代码：

@XmlRootElement(namespace = "http://www.myself.com/schema/me/v16", name = "history")
@XmlAccessorType(XmlAccessType.NONE)
public class History extends SuperRecord {
    private List<PatientHistoryFinding> medicalHistory;

    @XmlElement(name = "medicalHistory")
    @XmlElementWrapper(name = "medicalHistoryList")
    public List<PatientHistoryFinding> getMedicalHistory() {
        return medicalHistory;
    }
    public void setMedicalHistory(List<PatientHistoryFinding> medicalHistory) {
        this.medicalHistory = medicalHistory;
    }
}

@XmlRootElement(namespace = "http://www.myself.com/schema/me/v16", name = "patientHistoryFinding")
@XmlAccessorType(XmlAccessType.NONE)
public class PatientHistoryFinding extends HistoryFinding {

    private String question;

    @XmlElement
    public String getQuestion() {
        return question;
    }
    public void setQuestion(String question) {
        this.question = question;
    }
}

@XmlAccessorType(XmlAccessType.NONE)
public abstract class SuperRecord{
    protected int id;

    @XmlElement
    public int getId() {
        return id;
    }

    @Override
    public void setId(int id) {
        this.id = id;
    }
}

根据您的映射，预期的XML如下所示，您的XML可能没有相应的命名空间限定条件：

<?xml version="1.0" encoding="UTF-8"?>
<ns0:history xmlns:ns0="http://www.myself.com/schema/me/v16">
   <id>0</id>
   <medicalHistoryList>
      <medicalHistory/>
      <medicalHistory/>
   </medicalHistoryList>
</ns0:history>

请注意，根元素上的预期命名空间是由namespace类@XmlRootElement注释上指定的History引起的：

@XmlRootElement(namespace = "http://www.myself.com/schema/me/v16", name = "history")
@XmlAccessorType(XmlAccessType.NONE)
public class History extends SuperRecord {
