@Retention(RUNTIME) @Target({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:
- 可以与@XmlElementRef,@XmlElementRefs或@XmlAnyElement一起使用
以下内容可以插入到@XmlMixed注释的多值属性中
- XML文本信息项被添加为java.lang.String的值。
- 子元素信息项被添加为
JAXBElement
的实例,或具有使用@XmlRootElement注释的类的实例。 - 未绑定到JAXB映射类的未知内容将插入为
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 omitted.) 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>
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
