JAXB를 사용하여 다음 XML을 어떻게 생성 할 수 있습니까?
<sport type="" gender="">
sport description
</sport>
답변:
유형 및 성별 속성에 다음 @XmlAttribute
과 같이 주석을 달고 설명 속성에 주석을 추가합니다 @XmlValue
.
package org.example.sport;
import javax.xml.bind.annotation.*;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement
public class Sport {
@XmlAttribute
protected String type;
@XmlAttribute
protected String gender;
@XmlValue;
protected String description;
}
자세한 내용은
올바른 계획은 다음과 같아야합니다.
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.example.org/Sport"
xmlns:tns="http://www.example.org/Sport"
elementFormDefault="qualified"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
jaxb:version="2.0">
<complexType name="sportType">
<simpleContent>
<extension base="string">
<attribute name="type" type="string" />
<attribute name="gender" type="string" />
</extension>
</simpleContent>
</complexType>
<element name="sports">
<complexType>
<sequence>
<element name="sport" minOccurs="0" maxOccurs="unbounded"
type="tns:sportType" />
</sequence>
</complexType>
</element>
SportType에 대해 생성 된 코드는 다음과 같습니다.
package org.example.sport;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sportType")
public class SportType {
@XmlValue
protected String value;
@XmlAttribute
protected String type;
@XmlAttribute
protected String gender;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public String getType() {
return type;
}
public void setType(String value) {
this.type = value;
}
public String getGender() {
return gender;
}
public void setGender(String value) {
this.gender = value;
}
}
다음은 작업 솔루션입니다.
산출:
public class XmlTest {
private static final Logger log = LoggerFactory.getLogger(XmlTest.class);
@Test
public void createDefaultBook() throws JAXBException {
JAXBContext jaxbContext = JAXBContext.newInstance(Book.class);
Marshaller marshaller = jaxbContext.createMarshaller();
StringWriter writer = new StringWriter();
marshaller.marshal(new Book(), writer);
log.debug("Book xml:\n {}", writer.toString());
}
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "book")
public static class Book {
@XmlElementRef(name = "price")
private Price price = new Price();
}
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "price")
public static class Price {
@XmlAttribute(name = "drawable")
private Boolean drawable = true; //you may want to set default value here
@XmlValue
private int priceValue = 1234;
public Boolean getDrawable() {
return drawable;
}
public void setDrawable(Boolean drawable) {
this.drawable = drawable;
}
public int getPriceValue() {
return priceValue;
}
public void setPriceValue(int priceValue) {
this.priceValue = priceValue;
}
}
}
산출:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<book>

업데이트 된 솔루션-우리가 논의한 스키마 솔루션을 사용합니다. 이것은 당신의 대답을 얻습니다.
샘플 스키마 :

jaxb:version="2.0">
<complexType name="sportType">
<attribute name="type" type="string" />
<attribute name="gender" type="string" />
</complexType>
<element name="sports">
<complexType>
<sequence>
<element name="sport" minOccurs="0" maxOccurs="unbounded"

출력 클래스 파일은 명령 줄에서 스키마에 대해 xjc를 실행하여 생성됩니다.
