如何使用JAXB创建POJO的XML文件？
下面的代码段显示了如何使用JAXB将POJO转换为XML文件。为此，我们可以将要保存XML的输出文件传递到该marshaller对象。
package org.nhooo.example.jaxb;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import java.io.File;
public class JAXBObjectToXmlFile {
public static void main(String[] args) {
Track track = new Track();
track.setId(2);
track.setTitle("She Loves You");
try {
JAXBContext context = JAXBContext.newInstance(Track.class);
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
File output = new File("Track.xml");
marshaller.marshal(track, output);
} catch (JAXBException e) {
e.printStackTrace();
}
}
}此代码片段将创建一个文件Track.xml，其内容如下：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<track id="2">
<title>She Loves You</title>
</track>
