读取properties.xml配置文件的类

public class Utils {
	protected final static Logger log = Logger.getLogger(Utils.class);
	private static Properties props = new Properties();

	// 读取配置文件
	public static void readFile(String filePath) {
		try {
			InputStream in = new BufferedInputStream(new FileInputStream(
					filePath));
			props.load(in);
		} catch (Exception e) {
			log.debug("配置文件不存在");
			e.printStackTrace();
		}
	}

	/**
	 * @description:读取key对应的value
	 * @author:yehui
	 * @return:String
	 */

	public static String readValue(String key) {
		String value = props.getProperty(key);
		log.debug("key:"+value);
		return value;
	}

	//读取properties中全部内容
	public static void readProperties(String filePath) {
		Properties props = new Properties();
		try {
			InputStream in = new BufferedInputStream(new FileInputStream(
					filePath));
			props.load(in);
			Enumeration en = props.propertyNames();
			while (en.hasMoreElements()) {
				String key = (String) en.nextElement();
				String Property = props.getProperty(key);
				System.out.println(key + Property);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static Logger getLog() {
		return log;
	}

只需要传properties文件的path即可

借鉴了别人的代码。
