Spring_使用XML配置文件进行读取

痛定思痛。 2022-06-15 02:49 232阅读 0赞

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>
    </HD>
