Spring_使用XML配置文件进行读取

先去下载jdom配置文件包下载http://www.jdom.org/downloads/index.html

然后找到jdom-x.x.x.jar添加到项目JAR包中。

下面代码是对xml进行文件读取代码

package com.bjsxt.demo;

import java.util.List;

import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.input.SAXBuilder;

public class Sample1 {
public static void main(String[] args) throws Exception {
SAXBuilder sb = new SAXBuilder();// SAX生成
Document doc = sb.build(Sample1.class.getClassLoader().getResource(
"test.xml"));// 构造文档对象(文档路径生成)
Element root = doc.getRootElement();// 获取根元素
List list = root.getChildren("disk");// 取名字为disk的所有元素
for (int i = 0; i < list.size(); i++) {
Element element = (Element) list.get(i);
String name = element.getAttributeValue("name");
String capacity = element.getChildText("capacity");// 获取disk子元素capacity的内容
String directories = element.getChildText("directories");
String files = element.getChildText("files");
System.out.println("磁盘信息:");
System.out.println("分区盘符:" + name);
System.out.println("分区容量:" + capacity);
System.out.println("目录数:" + directories);
System.out.println("文件数:" + files);
System.out.println("----------------------------------");

}
}
}
<?xml version="1.0" encoding="UTF-8"?>
<HD>
<disk name="C">
<capacity>8G</capacity>
<directories>200</directories>
<files>1580</files>
</disk>

<disk name="D">
<capacity>10G</capacity>
<directories>500</directories>
<files>3000</files>
</disk>
