JAXB：如何在包装类型中获得价值？

Question

@XmlRootElement(name = "toplist")
class toplist {

    private String description;

    private List<Item> items= new ArrayList<Item>();

    @XmlElement(name = "description")
    public String getDescription() {...}
    public String setDescription() {...}

    @XmlElement(name = "item")
    @XmlElementWrapper(name = "items")
    public List<ChartResultItem> getToplistEntries() {...}
}

class Item {
    private String attr1;
    private String attr2;
    private String attr3;

    // getter and setter with
    //     @XmlAttribute(name = "atter1"), @XmlAttribute(name = "atter2") and etc
}

AND xml

<?xml version="1.0" encoding="UTF-8"?>
<toplist>
    <description>This is description.</description>
    <items>
        <item attr1="" attr2="" attr3="">value1</item>
        <item attr1="" attr2="" attr3="">value2</item>
        <item attr1="" attr2="" attr3="">value3</item>
        ...
    </items>
</toplist>

如何在Item类中获取value1，value2，value3等（通过jaxb）？

Answer 1

您可能正在寻找XmlValue注释。

Answer 2

Jom的回答是正确的（+1）。这是一个进一步解释的例子：

@XmlAccessorType(XmlAccessType.FIELD)
public class Item {
    @XmlValue
    protected String value;

    @XmlAttribute
    protected String attr1;

    @XmlAttribute
    protected String attr2;

    @XmlAttribute
    protected String attr3;
}
