Question

我有一个包含整数列表的类。此课程是从下面的XSD创建的。

  <xs:complexType name="Vehicle">
    <xs:sequence>
      <xs:element name="regNum" type="xs:string" />
      <xs:element name="company" type="xs:string" />
      <xs:element name="model" type="xs:string" />
      <xs:element name="lights" type="vehicle:Lights" />
    </xs:sequence>
  </xs:complexType>

  <xs:simpleType name="Lights">
    <xs:list>
      <xs:simpleType>
        <xs:restriction base="xs:int">
          <xs:minInclusive value="1" />
        </xs:restriction>
      </xs:simpleType>
    </xs:list>
  </xs:simpleType>

这产生了以下类：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Vehicle", propOrder = {
    "regNum",
    "company",
    "model",
    "lights"
})
@XmlSeeAlso({
    com.vcc.siig.domain.manual.vehicle.Car.class,
    com.vcc.siig.domain.manual.vehicle.Truck.class
})
public class Vehicle {

    @XmlElement(required = true)
    protected String regNum;
    @XmlElement(required = true)
    protected String company;
    @XmlElement(required = true)
    protected String model;
    @XmlList
    @XmlElement(type = Integer.class)
    @XmlSchemaType(name = "anySimpleType")
    protected List<Integer> lights;

    ...
}

当我从Vehicle Object编组到XML时。我收到以下错误：

Exception in thread "main" java.lang.ClassCastException: java.lang.Integer incompatible with java.lang.String

如果将Vehicle.lights设为null，我会得到XML。

我不确定这是我的xsd的错误还是问题。

JAXB java.lang.ClassCastException，同时编组整数列表
