Apache CXF，选择发生约束错误无法解析参数编号：“ {0}”

Question

我正在尝试执行以下脚本：Example 35.18. Choice Occurrence Constraints

我在示例中编写了完全相同的代码：

@XmlType(name = "ClubEvent", propOrder = {
"memberNameOrGuestName"
})
public class ClubEvent {

@XmlElementRefs({
    @XmlElementRef(name = "GuestName", type = JAXBElement.class),
    @XmlElementRef(name = "MemberName", type = JAXBElement.class)
})
protected List<JAXBElement<String>> memberNameOrGuestName;

public List<JAXBElement<String>> getMemberNameOrGuestName() {
    if (memberNameOrGuestName == null) {
        memberNameOrGuestName = new ArrayList<JAXBElement<String>>();
    }
    return this.memberNameOrGuestName;
}
}

但是当我尝试启动我的Spring Boot应用程序时，我有一个错误：

Caused by: javax.xml.ws.WebServiceException: java.lang.IllegalArgumentException: can't parse argument number: ''{0}''

我的项目正在使用带有Apache CXF 3.2.7的Spring Boot。在配置类中，这是例如端点的代码：

@Bean(name = "ship")
public Endpoint endpoint() {
    EndpointImpl endpoint = new EndpointImpl(bus(), new ShipImpl(shipDAO, callerDAO));
    endpoint.publish("/ship");
    return endpoint;
}
