生成的WSDL具有nillable =＆＃34; true＆＃34;对于@RequestWrapper

Question

我的问题是：如何设置CXF系统以使服务方法签名与客户端签名相同？即使使用@RequestWrapper？ 另请参阅两年前提出的问题：old question

在@WebMethod上使用@RequestWrapper时，会导致nillable =＆＃34; true＆＃34;在生成的WSDL中。 从这个WSDL我用Maven（cxf-codegen-plugin）生成java，当设置nillable时，方法的参数被包装。

@WebMethod(action = "getAvailableMoments")
@RequestWrapper(className = "webservice.wrappers.GetAvailableMomentsWrapper")
public List<Moment> getAvailableMoments(LocalDate selectedDate) {
}

包装器看起来像这样：

@XmlAccessorType(XmlAccessType.FIELD)
public class GetAvailableMomentsWrapper implements Serializable {
    private static final long serialVersionUID = 1L;

    @XmlElement(required = true)
    @XmlJavaTypeAdapter(value = LocalDateAdapter.class, type = LocalDate.class)
    @XmlSchemaType(name = "date")
    private LocalDate selectedDate;
}

然后wsdl的一部分看起来像这样：

...
<xs:element name="getAvailableMoments" nillable="true" type="tns:getAvailableMomentsWrapper"/>
...

然后生成的java代码如下所示：

@WebMethod(action = "getAvailableMoments")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
@WebResult(name = "getAvailableMomentsResponse", targetNamespace = "calendar.service.vetsware.nl", partName = "parameters")
public GetAvailableMomentsResponse getAvailableMoments(
    @WebParam(partName = "parameters", name = "getAvailableMoments", targetNamespace = "calendar.service.vetsware.nl")
    GetAvailableMomentsWrapper parameters
);

但是当我设置nillable =＆＃34; false＆＃34;时，java代码看起来像我想要的那样：

@WebMethod(action = "getAvailableMoments")
@RequestWrapper(localName = "getAvailableMoments", targetNamespace = "calendar.service.vetsware.nl", className = "nl.vetsware.service.calendar.GetAvailableMomentsWrapper")
@ResponseWrapper(localName = "getAvailableMomentsResponse", targetNamespace = "calendar.service.vetsware.nl", className = "nl.vetsware.service.calendar.GetAvailableMomentsResponse")
@WebResult(name = "return", targetNamespace = "")
public java.util.List<nl.vetsware.service.calendar.Moment> getAvailableMoments(
    @WebParam(name = "selectedDate", targetNamespace = "")
    java.time.LocalDate selectedDate
);
