xml – JAXB：IllegalAnnotationExceptions的2个计数

这是我的Parser类

public class Test {
    public static void main(String args[]) throws Exception {

        File file = new File("D:\\Test.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(MyOrder.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        MyOrder customer = (MyOrder) jaxbUnmarshaller.unmarshal(file);
        System.out.println(customer.getorder().getSide());
    }
}

这是MyOrder.java文件

@XmlRootElement(name = "BXML")
public class MyOrder {
    @XmlElement(name = "Bag")
    protected Order order;

    public MyOrder() {

    }
    @XmlAttribute
    public Order getorder() {
        return order;
    }
    public void setorder(Order order) {
        this.order = order;
    }
}

这是我的域对象(Order.java)

@XmlRootElement(name = "BXML")
public class Order {

    public Order() {

    }

    @XmlAttribute(name = "Side")
    protected BigInteger Side;

    @XmlValue
    public BigInteger getSide() {
        return Side;
    }

    public void setSide(BigInteger side) {
        Side = side;
    }
}

这是我试图运行程序时遇到的异常

Exception in thread "main" com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions
@XmlAttribute/@XmlValue need to reference a Java type that maps to text in XML.
    this problem is related to the following location:
        at public com.Order com.MyOrder.getorder()
        at com.MyOrder
Class has two properties of the same name "order"
    this problem is related to the following location:
        at public com.Order com.MyOrder.getorder()
        at com.MyOrder
    this problem is related to the following location:
        at protected com.Order com.MyOrder.order
        at com.MyOrder

对于@ XmlAttribute / @ XmlValue,需要引用映射到XML中的文本的java类型.问题您需要将JAXBContext的初始化更改为以下内容：

JAXBContext jaxbContext = JAXBContext.newInstance(new Class[] {MyOrder.class,Order.class});

对于Class有两个同名“order”问题的属性,需要更改受保护Order顺序的定义;私人订单;

此外,您希望将Order类的@XmlRootElement(name =“BXML”)更改为@XmlRootElement(name =“Order”).
