code1: colors類根節點

code1

package com.kangdy.test;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "Colors")
@XmlAccessorType(XmlAccessType.FIELD)
public class Colors {

   @XmlElement(name = "red",nillable=true)
   private Red red;

   @XmlElement(name = "blue",nillable=true)
   private Blue blue;

   public Red getRed() {
       return red;
   }

   public Blue getBlue() {
       return blue;
   }

   public void setRed(Red red) {
       this.red = red;
   }

   public void setBlue(Blue blue) {
       this.blue = blue;
   }
}

code2: Red類子節點

code2package com.kangdy.test;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "red")
@XmlAccessorType(XmlAccessType.FIELD)
public class Red {

   private String value;

   @XmlAttribute(name = "att1")
   private String att;

   public String getValue() {
       return value;
   }

   public void setValue(String value) {
       this.value = value;
   }

   public String getAtt() {
       return att;
   }

   public void setAtt(String att) {
       this.att = att;
   }

}

code3: 類 Blue 子節點

code3

package com.kangdy.test;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "blue")
@XmlAccessorType(XmlAccessType.FIELD)
public class Blue {
   private String value;

   @XmlAttribute(name = "att2")
   private String att2;

   @XmlAttribute(name = "att1")
   private String att;

   public String getAtt() {
       return att;
   }

   public void setAtt(String att) {
       this.att = att;
   }

   public String getValue() {
       return value;
   }

   public void setValue(String value) {
       this.value = value;
   }

   public String getAtt2() {
       return att2;
   }

   public void setAtt2(String att2) {
       this.att2 = att2;
   }
}

code4: main類

code4

package com.kangdy.test;

import java.io.StringWriter;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;

public class Jaxbtest {
   public static void main(String[] args) throws Exception {

       StringWriter writer = new StringWriter();
       JAXBContext jc = JAXBContext.newInstance(Colors.class);
       Marshaller ma = jc.createMarshaller();
       ma.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

       Colors colors = new Colors();
       Red red = new Red();
       red.setAtt("att-red");
       red.setValue("red");
       Blue blue = new Blue();
       blue.setValue("blue");
       blue.setAtt("att-blue");
       blue.setAtt2("blue-att2");
       colors.setRed(red);
       colors.setBlue(blue);

       ma.marshal(colors, writer);
       System.out.println(writer.toString());

   }
}

運行結果：

結果

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Colors>
    <red att1="att-red">
        <value>red</value>
    </red>
    <blue att1="att-blue" att2="blue-att2">
        <value>blue</value>
    </blue>
</Colors>
