我的供应商为我提供了一个XSD
,其元素定义为String
。但是在他的规范中,他表示此字符串只能包含3个值中的1个:
例如:
<xs:complexType name="MitigationStatus">
<xs:annotation>
<xs:documentation>
This represents a list of mitigation statuses. Can be OPEN, CLOSED, INVALID
</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element name="status" minOccurs="0" maxOccurs="unbounded" type="xs:string"/>
</xs:sequence>
</xs:complexType>
我想在我的绑定文件中添加一些内容,以便在我解冻XML
时,状态不是String
,而是Enum
。
我找到的所有文档似乎都表明XSD
要求String
属于enum
类型。
即使Enum
不是XSD
,有没有办法将字符串绑定到enum
类型?

您可以使用下面指示的更改稍微修改XML架构中的此限制,并从中生成Java类。
<jaxb:bindings node="//xsd:complexType[@name='MitigationStatus']">
<jaxb:bindings node="./xsd:element[@name='status']">
<jaxb:property>
<jaxb:baseType>
<jaxb:javaType name="StatusImpl"
parseMethod="StatusImpl.parseStringToEnum"
printMethod="StatusImpl.printEnumToString"/>
</jaxb:baseType>
</jaxb:property>
</jaxb:bindings>
</jaxb:bindings>
这将导致枚举类StatusType。在XML中,无论如何都是字符串,所以它保持原样。
如果您确实想通过绑定文件执行此操作,可以使用以下内容:
public class StatusImpl {
public static StatusType parseStringToEnum( String value ){
return StatusType.valueOf( value );
}
public static String printEnumToString( StatusType impl ){
return impl.toString();
}
}
假设枚举状态类型,类StatusImpl只是

我不知道你有什么问题,但以下工作正常。如您所见,没有XSD,只需手动编码JAXB类。
public class Test {
public static void main(String[] args) throws Exception {
String xml = "<Path>\r\n" +
" <Direction>North</Direction>\r\n" +
" <Direction>North</Direction>\r\n" +
" <Direction>East</Direction>\r\n" +
" <Direction>South</Direction>\r\n" +
"</Path>";
JAXBContext jaxbContext = JAXBContext.newInstance(Path.class);
Path path = (Path)jaxbContext.createUnmarshaller().unmarshal(new StringReader(xml));
for (Direction dir : path.directions)
System.out.println(dir);
}
}
@XmlEnum
enum Direction {
@XmlEnumValue("North") NORTH,
@XmlEnumValue("South") SOUTH,
@XmlEnumValue("East") EAST,
@XmlEnumValue("West") WEST
}
@XmlRootElement(name = "Path")
class Path {
@XmlElement(name = "Direction")
List<Direction> directions = new ArrayList<>();
}
输出
NORTH
NORTH
EAST
SOUTH
