注释 JavaBean 多值属性,以支持混合内容。
用法受到以下约束的限制:
以下内容可以插入 @XmlMixed 注释的多值属性中:
JAXBElement
实例或带有使用 @XmlRootElement 注释的类的实例添加。Element
插入。(假定已使用 @XmlAnyElement 对属性进行注释。)<!-- 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一个 XML 实例文档:
可以使用以下 JAXB API 调用来构造上述文档:<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
