使用XMLStreamWriter写XML

package com.hqh.stax;


import javax.xml.stream.FactoryConfigurationError;
import javax.xml.stream.XMLOutputFactory;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamWriter;

import org.junit.Test;

public class TestXMLStreamWriter {

	@Test
	public void test() {
		XMLStreamWriter writer = null;
		try {
			writer = XMLOutputFactory.newInstance().createXMLStreamWriter(System.out);
			//XML头
			writer.writeStartDocument("UTF-8", "1.0");
			writer.writeEndDocument();
			
			//正文
			writer.writeStartElement("person");
			writer.writeStartElement("id");
			writer.writeCharacters("1");
			writer.writeEndElement();
			writer.writeEndElement();
			
			//刷新流到目标
			writer.flush();
			
		} catch (XMLStreamException e) {
			e.printStackTrace();
		} catch (FactoryConfigurationError e) {
			e.printStackTrace();
		} finally {
			if(writer!=null) {
				try {
					writer.close();
				} catch (XMLStreamException e) {
					e.printStackTrace();
				}
			}
		}
	}

}

结果：
<?xml version="1.0" encoding="UTF-8"?><person><id>1</id></person>
