Java用JAXB解封对象列表

Question

我有如下所示的XML：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ObjectList>
  <object attributeOne="somedate" attributeTwo="false" attributeThree="id" attributeFour="true"/>
  <object attributeOne="somedate" attributeTwo="false" attributeThree="id" attributeFour="true"/>
  <object attributeOne="somedate" attributeTwo="false" attributeThree="id" attributeFour="true"/>
  <object attributeOne="somedate" attributeTwo="false" attributeThree="id" attributeFour="true"/>
  <object attributeOne="somedate" attributeTwo="false" attributeThree="id" attributeFour="true"/>
</ObjectList>

我有一个ObjectList类,它如下所示：

@XmlRootElement
public class ObjectList {

    @XmlElementWrapper(name = "ObjectList")
    @XmlElement(name = "Object")
    private ArrayList<Object> ObjectList;

    public ArrayList<Object> getObjectList() {
        return ObjectList;
    }

    public void html" target="_blank">setObjectList(ArrayList<Object> objectList) {
        ObjectList = objectList;
    }
}

和如下所示的对象类：

@XmlRootElement(name = "Object")
public class Object {

    Date attributeOne;
    boolean attritbuteTwo;
    String attributeThree;
    boolean attributeFour;

    @XmlAttribute
    public Date getAttributeOne() {
        return attributeOne;
    }
    public void setAttributeOne(Date attributeOne) {
        this.attributeOne = attributeOne;
    }

    @XmlAttribute
    public boolean isAttributeTwo() {
        return attritbuteTwo;
    }
    public void setAttributeTwo(boolean attritbuteTwo) {
        this.AttributeTwo = AttributeTwo;
    }

    @XmlAttribute
    public String getAttributeThree() {
        return attributeThree;
    }
    public void setAttributeThree(String attributeThree) {
        this.attributeThree = attributeThree;
    }

    @XmlAttribute
    public boolean isAttributeFour() {
        return attributeFour;
    }
    public void setAttributeFour(boolean attributeFour) {
        this.attributeFour = attributeFour;
    }
}

当我尝试使用以下代码将xml解封到and对象中时：

JAXBContext jaxbContext = JAXBContext.newInstance(ObjectList.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

RESTResponse response = getObjects();

ObjectList objects = (ObjectList) unmarshaller.unmarshal(new StringReader(response.getResponseBody()));

我得到以下错误：

UnMarshalException：意外元素（URI：“”，本地：“ObjectList”）。需要的元素为<{}Object>、<{}ObjectList>

编辑：我刚刚注意到两个问题我将我的ObjectList对象的XmlRootElement标记更改为@XmlRootElement（名称=“ObjectList”）并且将我的对象的XmlRootElement标记更改为@XmlRootElement（名称=“object”）。

非常感谢任何帮助。

好吧，它说的是预期元素:object或objectlist（以小写“O”开头），但它读的是objectlist（以大写“O”开头）！
