首先，我已经看过这里：
对于JodaTime使用JAXB.
我继承了一个代码库，其中的 impl（和 XML 适配器）在下面。
尝试使用for生成WSDL和客户端时，我得到以下信息：Apache CXF v2.7.2 Maven pluginjava2ws
Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
org.joda.time.base.BaseInterval does not have a no-arg default constructor.
this problem is related to the following location:
at org.joda.time.base.BaseInterval
at org.joda.time.MutableInterval
at com.etp.commons.persistence.model.time.Period
好吧，Period（下） extends MutableIntervalextends BaseIntervalextendsAbstractInterval在 中具有受保护的无参数构造函数JodaTime v2.1。 Period有一个公共的无参数构造函数，它调用MutableInterval传入一些默认值的构造函数变体。
关于如何进行的任何提示？

更新更多细节
假设我有这样的服务......
@WebService(targetNamespace="http://www.foo.com/DerivationModelServices")
public interface DerivationModelService extends InternalDerivationModelService{
public Determinant getDeterminant(DeterminantQueryParameters params) throws PersistenceServiceException;
public DeterminantDefinition getDeterminantDefinition(DeterminantDefinitionQueryParameters params) throws PersistenceServiceException;

public void saveReportDefinition(ReportDefinition def);
public PagedQueryResults<ReportDefinition> getReportDefinitions(ReportDefinitionsQueryParameters params);
public ReportDefinition getReportDefinition(ReportDefinitionQueryParameters params);
}
为什么我会得到无参数构造函数Period？此外，如果我将所有超级接口的方法都标记@WebMethod(excluded=true)为不暴露它们，我为什么会得到这个异常？我问是因为虽然我收到的第一个答案看起来像是要走的路，但我无法克服这个问题。（也许我没有在我的代码库中到处寻找所描述的案例？）
