Java DOM4J 方式生成XML文件

Dom4jCreateXML.java文件

package Dom4jCreateXMLFile;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;
import org.junit.Test;

public class Dom4jCreateXML {

	public void createXMLFile(File file) throws IOException {
		//创建一个文档模型
        Document document  = DocumentHelper.createDocument();
        //定义一个根节点bookstore
        Element bookstore = document.addElement("bookstore");
        //根节点下添加子节点book
        Element book = bookstore.addElement("book");
        //节点添加属性
        book.addAttribute("id", "1");
        //节点添加子节点并设置节点值
        Element name = book.addElement("name");
        name.addText("Hello World");
        Element author = book.addElement("author");
        author.addText("Azzan");
        Element year = book.addElement("year");
        year.addText("2017-04-25");
        Element price = book.addElement("price");
        price.addText("121.00");
        
        //创建XML格式
        OutputFormat xmlFormat = new OutputFormat();
        xmlFormat.setEncoding("UTF-8");
        xmlFormat.setNewlines(true);
        xmlFormat.setIndent("    ");
        FileWriter fileWriter = new FileWriter(file);
        XMLWriter xmlWriter = new XMLWriter(fileWriter,xmlFormat);
        xmlWriter.write(document);
        xmlWriter.close(); 
	}

	@Test
	public void test() throws IOException {
		File file =  new File("createBook.xml");
		createXMLFile(file);
	}

}

createBook.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<bookstore>
    <book id="1">
        <name>Hello World</name>
        <author>Azzan</author>
        <year>2017-04-25</year>
        <price>121.00</price>
    </book>
</bookstore>
