JAVA 动态加载properties配置文件

package cn.itcast.utils;

import java.io.IOException;
import java.util.Properties;

public class SUrl {
	private static Properties properties = new Properties();
	static{
		try {
			properties.load(SiteUrl.class.getClassLoader().getResourceAsStream("url.properties"));
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	public static String readUrl(String key){
		return properties.getProperty(key);
	}

<span style="white-space:pre">	</span>public static String getShortMsg(String arg){
<span style="white-space:pre">	</span>     String path = Thread.currentThread().getContextClassLoader().getResource("").getPath();
		 //获取绝对路径，完美解决动态加载properties
	     Properties prop = new Properties();
	     try {
	    	 InputStream in = new FileInputStream(path + "/con.properties");
	    	 prop.load(in);
	     }catch (FileNotFoundException e) {
				e.printStackTrace();
		 }catch (IOException e) {
	    	  e.printStackTrace();
	     }
	     
		 return prop.getProperty(arg);
	}
