java通过dom4j解析xml文件

java解析xml文件有很多种（dom4j、jdom）等等，下面记录下自己通过dom4j解析的xml的方法

1·首先解析的项目目录



2· 使用dom4j解析需要依赖的jar包就一个dom4j.jar包

3·解析的代码如下：

package com.util;

import java.util.ArrayList;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

import com.alibaba.fastjson.JSON;
import com.bean.XmlBean;

public class ParseXmlUtil {
public void parsexml() throws Exception{
SAXReader reader = new SAXReader();
/*读取resource.xml文件*/
Document document = reader.read("src/resource.xml");
/*获取xml文件的根节点*/
Element rootElement = document.getRootElement();
/*将获取到的根节点下的resourceitem节点放在list中*/
List items = rootElement.elements("resourceitem");
/*创建source存放每一个resourceitem中资源*/
List<XmlBean> beans = new ArrayList<XmlBean>();
for(int i = 0 ; i < items.size() ; i++){
XmlBean bean = new XmlBean();
Element resourceitem = (Element)items.get(i);
String id = resourceitem.element("id").getText();
String title = resourceitem.element("title").getText();
String keywords = resourceitem.element("keywords").getText();
String kind = resourceitem.element("kind").getText();
String describe = resourceitem.element("describe").getText();
String date = resourceitem.element("date").getText();
String url = resourceitem.element("url").getText();
String author = resourceitem.element("author").getText();
String publisher = resourceitem.element("publisher").getText();
bean.setAuthor(author);
bean.setDate(date);
bean.setDescribe(describe);
bean.setId(id);
bean.setKeywords(keywords);
bean.setKind(kind);
bean.setTitle(title);
bean.setUrl(url);
beans.add(bean);
}
System.out.println(JSON.toJSONString(beans));

}
}

4·我的资源文件的resource.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<allresource host="192.168.0.81" remote="192.168.0.82">
<resourceitem>
<id>1</id>
<title>锋利的jquery</title>
<keywords>jquery</keywords>
<kind>chm</kind>
<describe>详细描写jquery的书</describe>
<date>2015-03-25 00:17:01</date>
<url>http://192.168.0.81/book</url>
<author>释然</author>
<publisher>人民出版社</publisher>
</resourceitem>
<resourceitem>
<id>2</id>
<title>疯狂java基础讲义</title>
<keywords>java</keywords>
<kind>chm</kind>
<describe>讲解java的入门书籍</describe>
<date>2015-03-25 00:19:10</date>
<url>http://192.168.0.81:8080/</url>
<author>shiran</author>
<publisher>人民出版社</publisher>
</resourceitem>
</allresource>

5·需要创建的bean类

package com.bean;

public class XmlBean {
private String id;
private String title;
private String keywords;
private String kind;
private String describe;
private String date;
private String url;
private String author;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getKeywords() {
return keywords;
}
public void setKeywords(String keywords) {
this.keywords = keywords;
}
public String getKind() {
return kind;
}
public void setKind(String kind) {
this.kind = kind;
}
public String getDescribe() {
return describe;
}
public void setDescribe(String describe) {
this.describe = describe;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}

}

6·进行测试：

package com.test;

import com.util.ParseXmlUtil;

public class TestParseXml {

/**
* @param args
*/
public static void main(String[] args) {
ParseXmlUtil xmlUtil = new ParseXmlUtil();
try {
xmlUtil.parsexml();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

7·结果 ：

[{"author":"释然","date":"2015-03-25 00:17:01","describe":"详细描写jquery的书","id":"1","keywords":"jquery","kind":"chm","title":"锋利的jquery","url":"http://192.168.0.81/book"},
{"author":"shiran","date":"2015-03-25 00:19:10","describe":"讲解java的入门书籍","id":"2","keywords":"java","kind":"chm","title":"疯狂java基础讲义","url":"http://192.168.0.81:8080/"}]
