java - Jersey REST 日期 @XmlAttribute 导致非法参数异常

Question

我有一个 Jersey REST Web 服务，它接受 POSTed XML 字符串。我为 XML 的每个元素都有实体，以便将它们拆分为对象。当我传递日期参数时，例如InspectionDate="12/02/2012"我收到以下错误。

这是我的 XML 字符串:

        </site>
      </client>
    </user>

这是我的实体类的片段:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {"inspectionDate"})

public class Inspection {

    @XmlAttribute
    protected Date inspectionDate;

    @XmlAttribute
    protected String inspectionRef;

        public Date getInspectionDate() {
        return inspectionDate;
    }

    public void setInspectionDate(Date inspectionDate) {
        this.inspectionDate = inspectionDate;
    }
}

如果我使用以下 XMLJavaAdapter:

public class DateAdapter extends XmlAdapter<String, Date> {

    private SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");

    @Override
    public String marshal(Date v) throws Exception {
        return dateFormat.format(v);
    }

    @Override
    public Date unmarshal(String v) throws Exception {
        return dateFormat.parse(v);
    }

}

我收到以下错误:

如果有人有任何想法，请告诉我。

Answer 1

我的猜测是，您正在获取两个属性...，异常(exception)的是，在您的真实类中，您在 get 方法上添加了 @XmlJavaTypeAdapter(DateAdapter.class) 注释，而不是在具有 @XmlAttribute 注释的字段。
