手动 fieldproperty XML 映射配置
注释 @XmlElement
, @XmlAttribute
或 @XmlTransient
以及 javax.xml.bind.annotation
包中的其他内容允许程序员指定应该序列化哪些以及如何标记的字段或属性。
@XmlAccessorType(XmlAccessType.NONE) // we want no automatic field/property marshalling
public class ManualXmlElementsExample {
@XmlElement
private String field="field value";
@XmlAttribute
private String attribute="attr value";
@XmlAttribute(name="differentAttribute")
private String oneAttribute="other attr value";
@XmlElement(name="different name")
private String oneName="different name value";
@XmlTransient
private String transientField = "will not get serialized ever";
@XmlElement
public String getModifiedTransientValue() {
return transientField.replace(" ever", ", unless in a getter");
}
public void setModifiedTransientValue(String val) {} // empty on purpose
public static void main(String[] args) {
try {
JAXB.marshal(new ManualXmlElementsExample(), System.out);
} catch (Exception e) {
System.err.println("Exception occurred while writing in XML!");
}
}
}
