javax.xml.bind.annotation
註釋型別 XmlMixed


@Retention(value=RUNTIME)
@Target(value={FIELD,METHOD})
public @interface XmlMixed

註釋 JavaBean 多值屬性,以支持混合內容。

用法受到以下約束的限制:

以下內容可以插入 @XmlMixed 註釋的多值屬性中:

以下是綁定和創建混合內容的一個範例:

  <!-- schema fragment having  mixed content -->
  <xs:complexType name="letterBody" mixed="true">
    <xs:sequence>
        <xs:element name="name" type="xs:string"/>
        <xs:element name="quantity" type="xs:positiveInteger"/>
        <xs:element name="productName" type="xs:string"/>
        <!-- etc. -->
    </xs:sequence>
  </xs:complexType>
  <xs:element name="letterBody" type="letterBody"/>
 
 // Schema-derived Java code: 
 // (Only annotations relevant to mixed content are shown below, 
 //  others are ommitted.)
 import java.math.BigInteger;
 public class ObjectFactory {
        // element instance factories
        JAXBElement<LetterBody> createLetterBody(LetterBody value);
        JAXBElement<String>     createLetterBodyName(String value);
        JAXBElement<BigInteger> createLetterBodyQuantity(BigInteger value);
        JAXBElement<String>     createLetterBodyProductName(String value);
      // type instance factory
        LetterBody> createLetterBody();
 }
 
 public class LetterBody {
        // Mixed content can contain instances of Element classes
        // Name, Quantity and ProductName. Text data is represented as
        // java.util.String for text.
        @XmlMixed 
        @XmlElementRefs({
                @XmlElementRef(name="productName", type=JAXBElement.class),
                @XmlElementRef(name="quantity", type=JAXBElement.class),
                @XmlElementRef(name="name", type=JAXBElement.class)})
        List getContent(){...}
 }
 
以下是具有混合內容的一個 XML 實例文檔:

 <letterBody>
Dear Mr.<name>Robert Smith</name>
Your order of <quantity>1</quantity> <productName>Baby
Monitor</productName> shipped from our warehouse. ....
 </letterBody>
 
可以使用以下 JAXB API 調用來建構上述文檔:

LetterBody lb = ObjectFactory.createLetterBody();
JAXBElement<LetterBody> lbe = ObjectFactory.createLetterBody(lb);
List gcl = lb.getContent();  //add mixed content to general content property.
gcl.add(&quot;Dear Mr.&quot;);  // add text information item as a String.
 
// add child element information item
gcl.add(ObjectFactory.createLetterBodyName(&quot;Robert Smith&quot;));
gcl.add(&quot;Your order of &quot;); // add text information item as a String
 
// add children element information items
gcl.add(ObjectFactory.
                        createLetterBodyQuantity(new BigInteger(&quot;1&quot;)));
gcl.add(ObjectFactory.createLetterBodyProductName(&quot;Baby Monitor&quot;));
gcl.add(&quot;shipped from our warehouse&quot;);  // add text information item
