Java配置文件读取示例-优快云博客

本文介绍如何在Java中读取properties及XML配置文件。通过示例代码展示了使用Properties类加载properties文件的方法，以及利用SAXReader和Document对象解析XML文件的过程。

1. 读properties文件

Properties prop = new Properties();
InputStream in = this.class.getClassLoader().getResourceAsStream("cn/com/sever.properties");
prop.load(in);
String b2bic_ip = prop.getProperty("b2bic.sever.ip").trim();
in.close();

2. 读xml文件

Setting setting = new Setting();
File lppzXmlFile = new ClassPathResource("cn/aa.xml").getFile();
Document document = new SAXReader().read(lppzXmlFile);
List elements = document.selectNodes("/lppz/setting");
for (Element element : elements) {
	String name = element.attributeValue("name");
	String value = element.attributeValue("value");
	try {
		beanUtils.setProperty(setting, name, value);
	} catch (IllegalAccessException e) {
		e.printStackTrace();
	}
}

Element element = null;
// 可以使用绝对路劲
File f = new File("D:/aa.xml");
DocumentBuilder db = null;
DocumentBuilderFactory dbf = null;
try {
	dbf = DocumentBuilderFactory.newInstance();
	db = dbf.newDocumentBuilder();
	Document dt = db.parse(f);
	element = dt.getDocumentElement();
	System.out.println("根元素：" + element.getNodeName());
	NodeList childNodes = element.getChildNodes();
	for (int i = 0; i < childNodes.getLength(); i++) {
		Node node1 = childNodes.item(i);
		if ("Account".equals(node1.getNodeName())) {
			node1.getAttributes().getNamedItem("type").getNodeValue();
			NodeList nodeDetail = node1.getChildNodes();
			for (int j = 0; j < nodeDetail.getLength(); j++) {
				Node detail = nodeDetail.item(j);
				if ("code".equals(detail.getNodeName())) // 输出code
					System.out.println("卡号: " + detail.getTextContent());
			}
		}
	}
} catch (Exception e) {
	e.printStackTrace();
}
