继承映射抛出异常与MOXy

我遵循JAXB inheritance in MOXY中提到的第二个选项来映射我的父类和子类。莫西抛出以下异常，并不能确定是什么问题继承映射抛出异常与MOXy

父类

public class UnitedStatesAddressData extends AbstractAddress implements UnitedStatesAddress, Serializable, Cloneable 
{ 
    private String primaryAddress; 

    public String getPrimaryAddress() 
    { 
     return primaryAddress; 
    } 

    public void setPrimaryAddress(final String primaryAddress) 
    { 
     this.primaryAddress = primaryAddress; 
    } 
}

子类

public class TokenizedUnitedStatesAddressData extends UnitedStatesAddressData implements TokenizedUnitedStatesAddress, 
     CloneableAddress 
{ 
    private String houseNumber; 

    private String preDirectional; 

    private String streetName; 

    private String streetType; 

//getters and setters ignored 
}

UPDATE

我已经通过去除“丙顺序”测试这一点，并能正常工作除了我不能再控制中产生的元素的顺序XML。我相信这是代码中的一个错误。

原因是子类重写了父类的方法，如下所示，但由于父类已被定义为xml-transient =“true”，因此TypeInfo的下面的检查失败。

子类中重写getPrimaryAddress

public class TokenizedUnitedStatesAddressData extends UnitedStatesAddressData implements TokenizedUnitedStatesAddress, 
     CloneableAddress 
{ 
@override 
public String getPrimaryAddress() 
{ 
    return primaryAddress; 
} 
}

TypeInfo.java违规代码

if (p.isTransient() && propOrderList.contains(p.getPropertyName())) 
{ 
throw org.eclipse.persistence.exceptions.JAXBException.transientInProporder(p.getPropertyName()); 
}

更新2

该问题不在AbstractAddress中。一些调试后，这个问题似乎是与下面的逻辑在AnnotationProcessor.getPropertyPropertiesForClass(final JavaClass cls, final TypeInfo info, final boolean onlyPublic, final boolean onlyExplicit)

if ((setMethod == null) && !(hasJAXBAnnotations(getMethod))) 
{ 
    // if there's no corresponding setter, and not explicitly 
    // annotated, don't process 
    isPropertyTransient = true; 
}

这种方法标签不具有定义为“短暂” 都的get/set方法的任何方法。在我的情况下，我只覆盖TokenizedUnitedStatesAddressData类中的getPrimaryAddress()方法，而不是相应的setter。因此，Annotationprocessor将其指定为瞬态属性，忽略了这种方法被覆盖的事实。

FIX

问题是确保被覆盖的方法是在短暂的检查处理不当如下图所示

if ((setMethod == null) && !(hasJAXBAnnotations(getMethod))) 
{ 
    if (!isMethodOverrriden(cls.getQualifiedName(), getMethod.getName())) 
    { 
     // if there's no corresponding setter, and not explicitly 
     // annotated, don't process 
     isPropertyTransient = true; 
    } 
} 

public static boolean isMethodOverrriden(final String classQualifiedName, final String methodName) 
    { 
     Method myMethod; 
     try 
     { 
      myMethod = Class.forName(classQualifiedName).getMethod(methodName, null); 
     } 
     catch (Exception e1) 
     { 
      return false; 
     } 

     Class<?> declaringClass = myMethod.getDeclaringClass(); 
     if (declaringClass.equals(Object.class)) 
     { 
      return false; 
     } 

     Class<?> superclass = declaringClass.getSuperclass(); 
     if (superclass == null) 
     { 
      return false; 
     } 
     else 
     { 
      try 
      { 
       superclass.getMethod(myMethod.getName(), myMethod.getParameterTypes()); 
      } 
      catch (NoSuchMethodException e) 
      { 
       // recursively check all super classes 
       isMethodOverrriden(superclass.getName(), methodName); 
      } 
      return true; 
     } 
    }

这不是一个bug，问题是在你的模型中'AbstractAddress'仍然是一个映射类。请参阅：http://stackoverflow.com/a/11908405/383861 – 2012-08-11 11:26:21

即使您已标记后固定UnitedStatesAddressData为@XmlTransient（使用莫西的外部映射文档），它的超类AbstractAddress仍然是映射类。由于AbstractAddress的此类属性无法在TokenizedUnitedStatesAddressData的propOrder设置中指定。解决办法也是制作AbstractAddress@XmlTransient。

修复

我已经修改了你的映象文件要做到这一点下面假设AbstractAddress类在同一个包中域模型的其余部分。
