java 泛型带参数实例化

首先要把构造函数中的基本类型转换成基础类，例如int->Integer

	/**
	 * 得到带构造的类的实例
	 * */
	public static Object newInstance(String className, Object[] args) throws Exception {     
	    Class newoneClass = Class.forName(className);                                 
	    Class[] argsClass = new Class[args.length];                                   
	    for (int i = 0, j = args.length; i < j; i++) {                                
	        argsClass[i] = args[i].getClass();                                        
	    }	  
	    Constructor cons = newoneClass.getConstructor(argsClass);	    
	    return cons.newInstance(args);                                                 
	}
