            val writeMethod = clazz.getDeclaredMethod(writeMethodName, it.type)
            writeMethod.invoke(product,13)*/

        	//通过Introspector获取javaBean信息
            val beanInfo = Introspector.getBeanInfo(clazz)
        	//通过beanInfo获取到所有的属性描述,遍历获取它们的set方法
            beanInfo.propertyDescriptors.forEach {
                println(it.writeMethod)
            }
