dom4j读写XML及封存批量数据对象

dom4j读写XML及保存批量数据对象

1. 创建一个People对象

package XML;public class People {public People() {// TODO Auto-generated constructor stub}   private String name;   private int age;   private String sex;      public void tell(){  //取得信息的方法       System.out.println(" 姓名:"+this.getName()+"  年龄:"+this.getAge()+"  性别:"+this.getSex());   }      public People(String name,int age,String sex){   this.setName(name);   this.setAge(age);   this.setSex(sex);   }   public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {if(age&gt;=0){this.age = age;}else{this.age = 0;}}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}   public static void main(String args[]){     new People("wangwu",-10,"男").tell();   } }

2. 创建，解析XML及导入批量数据到XML中

package XML;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.DocumentHelper;import org.dom4j.Element;import org.dom4j.io.OutputFormat;import org.dom4j.io.XMLWriter;import org.dom4j.io.SAXReader;import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.util.ArrayList;import java.util.Iterator;import java.util.List;public class XmlOperate {//创建XMLpublic void CreateXml(){   Document doc = DocumentHelper.createDocument();      //创建文档  (树形结构)  Element e1 = doc.addElement("province");          //定义根节点 (第一层)  Element e2 = e1.addElement("people");               //定义子节点(第二层)  Element name1 = e2.addElement("name");          //定义子节点(第三层)  Element age1 = e2.addElement("age");                //定义子节点(第三层)  Element sex1 = e2.addElement("sex");                //定义子节点(第三层)    name1.setText("张三");                                       //设置子节点内容  age1.setText("30");   sex1.setText("男");  Element xe2 = e1.addElement("people");        //定义子节点(第二层)  Element name2 = xe2.addElement("name");    //定义子节点(第三层)  Element age2 = xe2.addElement("age");        //定义子节点(第三层)  Element sex2 = xe2.addElement("sex");         //定义子节点(第三层)   name2.setText("李四");                                    //设置子节点内容 age2.setText("29");  sex2.setText("女");  OutputFormat format= OutputFormat.createPrettyPrint();       //设置输出格式  format.setEncoding("GBK");                           //设置输出编码   try {       XMLWriter write = new  XMLWriter(new FileOutputStream("D:"+File.separator+"output.xml"),format);  //创建输出文件     write.write(doc);                           //输出     write.close();       System.out.println("xml文件创建成功！");        } catch (IOException e) {           e.printStackTrace();        }    }   //解析XML   public void ReadXml(){    File file1 = new File("D:"+File.separator+"output.xml");    //读取XML文件对象   SAXReader read=new SAXReader();              //建立SAX解析读取   Document doc = null;                                     //创建文档     try {doc= read.read(file1);            } catch (DocumentException e) {e.printStackTrace();            }       //取得根元素     Element root= doc.getRootElement();                  //取得全部的子节点     Iterator it1= root.elementIterator();        while(it1.hasNext()){              Element linkname=(Element)it1.next();    //取得一个节点对象         System.out.print("姓名:"+linkname.elementText("name"));                 //取得name元素内容        System.out.print(" 年龄:"+linkname.elementText("age"));                //取得age元素内容       System.out.println(" 性别:"+linkname.elementText("sex"));             //取得sex元素内容     } //取得节点 id="test" 里边的数据   }//批量数据生成xmlpublic void ImpAllXml(List&lt;People&gt; people){Document doc = DocumentHelper.createDocument();            //创建文档Element root= doc.addElement("shanxi");                     //创建根节点int  m= people.size();for(int i=0; i&lt;m; i++){  Element ele =root.addElement("people");       //定义对象节点  ele.addAttribute("id", "test"+(i+1)+"");           //增加节点属性  Element name = ele.addElement("name");      //定义属性节点   Element age = ele.addElement("age");                       Element sex = ele.addElement("sex");   name.setText(people.get(i).getName());         //为对应节点赋值  age.setText(String.valueOf(people.get(i).getAge()));   sex.setText(people.get(i).getSex());}  OutputFormat format= OutputFormat.createPrettyPrint();          //设置输出格式   format.setEncoding("GBK");                                //设置输出编码 try {   XMLWriter write = new XMLWriter(new FileOutputStream("D:"+File.separator+"test.xml"),format);    write.write(doc);    write.close();    System.out.println("创建text.xml文件成功！");     } catch (IOException e) {e.printStackTrace();       }}/** * xml创建和解析 */public static void main(String[] args) {// TODO Auto-generated method stubXmlOperate  xml = new XmlOperate();//xml.ReadXml();             //读取xml//批量数据生成xmlList&lt;People&gt; list = new ArrayList&lt;People&gt;();  list.add(new People("川",28,"男") ); list.add(new People("春",28,"男")); list.add(new People("小田",28,"男")); list.add(new People("liu",32,"男")); list.add(new People("燕",26,"女")); list.add(new People("郭",29,"男"));xml.ImpAllXml(list); }}

3.相关的XML

&lt;?xml version="1.0" encoding="GBK"?&gt;&lt;province&gt;  &lt;people&gt;    &lt;name&gt;张三&lt;/name&gt;    &lt;age&gt;30&lt;/age&gt;    &lt;sex&gt;男&lt;/sex&gt;  &lt;/people&gt;  &lt;people id="test"&gt;    &lt;name&gt;李四&lt;/name&gt;    &lt;age&gt;20&lt;/age&gt;    &lt;sex&gt;女&lt;/sex&gt;  &lt;/people&gt;&lt;/province&gt;

&lt;?xml version="1.0" encoding="GBK"?&gt;&lt;shanxi&gt;  &lt;people id="test1"&gt;    &lt;name&gt;川&lt;/name&gt;    &lt;age&gt;28&lt;/age&gt;    &lt;sex&gt;男&lt;/sex&gt;  &lt;/people&gt;  &lt;people id="test2"&gt;    &lt;name&gt;春&lt;/name&gt;    &lt;age&gt;28&lt;/age&gt;    &lt;sex&gt;男&lt;/sex&gt;  &lt;/people&gt;  &lt;people id="test3"&gt;    &lt;name&gt;小田&lt;/name&gt;    &lt;age&gt;28&lt;/age&gt;    &lt;sex&gt;男&lt;/sex&gt;  &lt;/people&gt;  &lt;people id="test4"&gt;    &lt;name&gt;liu&lt;/name&gt;    &lt;age&gt;32&lt;/age&gt;    &lt;sex&gt;男&lt;/sex&gt;  &lt;/people&gt;  &lt;people id="test5"&gt;    &lt;name&gt;燕&lt;/name&gt;    &lt;age&gt;26&lt;/age&gt;    &lt;sex&gt;女&lt;/sex&gt;  &lt;/people&gt;  &lt;people id="test6"&gt;    &lt;name&gt;郭&lt;/name&gt;    &lt;age&gt;29&lt;/age&gt;    &lt;sex&gt;男&lt;/sex&gt;  &lt;/people&gt;&lt;/shanxi&gt;
