properties配置文件：

username=mike
      pwd=123           

public class UtilBundle{

       public static String getValue(String username,String pwd){
        
              ResourceBundle resource=ResourceBundle.getBundle("config");//根据ResourceBundle类来读取配置文件中信息                                                                          
        	 if(resource!=null){
        		username=resource.getString(username);//通过getString()方法获取value的值
        	    pwd=resource.getString(pwd);
        	 }else{
        		 username=null;
        		 pwd=null;
        	 }
        	 
        	 return username+","+pwd;
         }

}           

public class TestBundle {
         public static void main(String[] args) {
		String value=UtilBundle.getValue("username","pwd");
        	 System.out.println("value:"+value);
		}
}
