在XML和自定义绑定中具有匿名内部类型的JAXB ClassCastException

<xs:element name="shiporder">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="item" minOccurs="0" nillable="true" maxOccurs="unbounded">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="title" type="xs:string"/>
                        <xs:element name="item" minOccurs="0" nillable="true" maxOccurs="unbounded">
                            <xs:complexType>

                                    <xs:element name="note" type="xs:string" minOccurs="0"/>

以及以下绑定.xjb

<jxb:bindings version="1.0"

<shiporder>

    <title>string1</title>
     <item>

import test.Shiporderrrr;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Unmarshaller;
import java.nio.file.Paths;

public class JaxbTest {
    public static void main(String[] args) {
       try {
        JAXBContext jaxbContext = JAXBContext.newInstance(Shiporderrrr.class);
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        Shiporderrrr shiporder = (Shiporderrrr)unmarshaller.unmarshal(Paths.get("src/main/resources/model1.xml").toFile());
        System.out.println(shiporder.getItems().get(0).getValue().getTitle());
    } catch (Exception e) {
        e.printStackTrace();
    }
}
}

我得到以下例外:

你能帮我查出我在这里做错了什么吗?

我应该以其他方式重写绑定吗?
