通过Java的反射动态调用类的set和get方法

public static <T> void testGetOrSet(List<T> list) throws IntrospectionException, IllegalArgumentException, IllegalAccessException, InvocationTargetException{
        Class tClass = list.get(0).getClass();
        //获得该类的所有属性
        Field[] fields = tClass.getDeclaredFields();
        for(Field field:fields){
            PropertyDescriptor pd = new PropertyDescriptor(field.getName(), tClass);
            //获得set方法
            Method method = pd.getWriteMethod();
            method.invoke(list.get(0), new Object[]{"123"});
            //获得get方法
            Method get = pd.getReadMethod();
            Object getValue = get.invoke(list.get(0), new Object[]{});
            System.out.println("field:"+field.getName()+"---getValue:"+getValue);
        }
    }
