jaxb2簡化xs的插件：具有相同類型的選擇

Question

我試圖使用jaxb2基礎爲我的模式簡化JAXB插件的插件。 它適用於像下面這樣的複雜類型。 xs:choice中定義的每個元素都有不同的類型（type1和type2）。

sample.xsd（複雜類型的選擇具有不同的類型）

<xs:complexType name="doclist"> 
    <xs:sequence> 
     <xs:choice minOccurs="0" maxOccurs="unbounded"> 
      <xs:annotation> 
       <xs:appinfo> 
        <simplify:as-element-property /> 
       </xs:appinfo> 
      </xs:annotation> 
      <xs:element name="document1" type="type1" /> 
      <xs:element name="document2" type="type2" /> 
     </xs:choice> 
    </xs:sequence> 
    <xs:attribute name="heading" type="xs:string" /> 
</xs:complexType> 

但是，如果複雜類型包含具有相同的類型（xs:string）多於一個的元件，如下所示，然後Maven的安裝拋出錯誤。

sample.xsd（複選類型同類型）

<xs:complexType name="addressTEST"> 
    <xs:choice minOccurs="0" maxOccurs="unbounded"> 
     <xs:annotation> 
      <xs:appinfo> 
       <simplify:as-element-property /> 
      </xs:appinfo> 
     </xs:annotation> 
     <xs:element name="street" type="xs:string" /> 
     <xs:element name="city" type="xs:string" /> 
    </xs:choice> 
</xs:complexType> 

是否JAXB2簡化，如果我有相同類型的多個元素將無法​​正常工作？

Answer 1

它應該可以工作，但可以嘗試自定義其中一個xs:element。

根據所生產的房產類型，您需要自定義xs:choice或其中一個子xs:elements。

如果您收到「元素」屬性，請自定義xs:choice。見the documentation。這是你在第一種情況下所擁有的。

如果您收到「元素引用」屬性，請自定義其中一個xs:elements。請參閱the documentation。這是你在第二種情況下所擁有的。
