@Retention(value=RUNTIME) @Target(value={字段,METHOD}) public @interface XmlMixed
注释JavaBean多值属性以支持混合内容。
用法受以下限制:
以下内容可以插入到@XmlMixed注释的多值属性中
JAXBElement
的实例,或具有使用@XmlRootElement注释的类的实例。 Element
。 (假定用@XmlAnyElement注释的属性) <!-- 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(){...}
}
以下是具有混合内容的XML实例文档
<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调用构建。
LetterBody lb = ObjectFactory.createLetterBody();
JAXBElement<LetterBody> lbe = ObjectFactory.createLetterBody(lb);
List gcl = lb.getContent(); //add mixed content to general content property.
gcl.add("Dear Mr."); // add text information item as a String.
// add child element information item
gcl.add(ObjectFactory.createLetterBodyName("Robert Smith"));
gcl.add("Your order of "); // add text information item as a String
// add children element information items
gcl.add(ObjectFactory.
createLetterBodyQuantity(new BigInteger("1")));
gcl.add(ObjectFactory.createLetterBodyProductName("Baby Monitor"));
gcl.add("shipped from our warehouse"); // add text information item
