没有setter方法时，利用反射给自定义(Java)对象set值(JSONObject 转 自定义(Java)对象)

public  T convertJSONObjectToObject(JSONObject data, Class beanClass) 
		throws InstantiationException, IllegalAccessException{
	Object objClass = beanClass.newInstance();
	Field[] declaredFields = beanClass.getDeclaredFields();
	for (Field field : declaredFields) {
		int modifier = field.getModifiers();
		//检查变量是否为 Static 或者 Final
		if(Modifier.isStatic(modifier) || Modifier.isFinal(modifier)) {
			continue;
		}
		
		field.setAccessible(true);
		//field.getName(): Field对象的变量名
		//field.getGenericType(): Field对象的类型
		filed.set(objClass, data.getObject(field.getName(), field.getGenericType()))
	}
	return (T)objClass;
}
