java - XmlElementWrapper 和附加的奇怪值

Question

在我的代码中我有这个 bean:

@XmlRootElement
@XmlAccessorType(XmlAccessType.NONE)
public class Data implements Serializable {

@XmlAttribute
private String _name;

@XmlElementWrapper(name = "statuses")
@XmlElement(name="status")
    private List<Boolean> _statuses;

public String getName() {
    return _name;
}

public void setName(String name) {
    _name = name;
}

    public List<Boolean> getStatuses() {
        return _statuses;
    }

    public void setStatuses(List<Boolean> statuses) {
        _statuses = statuses;
    }

 ....

}

这是编码(marshal) bean 的代码:

Writer w = null;
    try {
        final JAXBContext context = JAXBContext.newInstance(Data.class);
        final Marshaller m = context.createMarshaller();
        m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
        w = new FileWriter("file.xml");
        m.marshal(obj, w);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try { w.close();}
        catch (Exception e) {}
    }

我的期望是:

<data name="data-test">
<statuses>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
</statuses>
...
</data>

但是我得到了:

<data name="data-test">
<statuses>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
    <status>true</status>
</statuses>

// strange repetition
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>
<statuses>true</statuses>

// attribute as separated element
<name>data-test</name>
...
</data>

如何避免这种奇怪的重复？

我的猜测是访问类型不起作用。您尝试过XmlAccessType.FIELD吗？另外，请确保您已经正确编译了您的类并且您的类路径设置正确(也许您有一个来自早期测试的旧类？)。

更新:

您可以尝试将 @XmlTransient 显式添加到 getter/setter 吗？
