上代码：

public static void main(String[] args) throws IntrospectionException {        SysUser obj = new SysUser();        obj.setId(1L);        obj.setUserName("测试");        obj.setCreatedDate(LocalDateTime.now());        Class
      clazz = SysUser.class;        Field[] tableFields = clazz.getDeclaredFields();        Class
      superClazz = clazz.getSuperclass();        if (superClazz.equals(Object.class)) {            System.out.println("没有父类");        } else {            Field[] tableSuperFields = superClazz.getDeclaredFields();            Field[] superFields = new Field[tableFields.length + tableSuperFields.length];            System.arraycopy(tableFields, 0, superFields, 0, tableFields.length);            System.arraycopy(tableSuperFields, 0, superFields, tableFields.length, tableSuperFields.length);            Field[] allFields = getSuperClassFields(superFields, superClazz);            for (int i = 0; i < allFields.length; i++) {                PropertyDescriptor pd = new PropertyDescriptor(allFields[i].getName(), clazz);                Method getMethod = pd.getReadMethod();//获得get方法                Object fieldValue = ReflectionUtils.invokeMethod(getMethod, obj);                if(fieldValue == null){                    continue;                }                System.out.println(allFields[i].getName() + "的值：" +  fieldValue.toString());            }        }    }    //获取父类的所有字段    private static Field[] getSuperClassFields(Field[] tableFields, Class
      clazz) {        Class
      superClazz = clazz.getSuperclass();        if (superClazz.equals(Object.class)) {            return tableFields;        }        Field[] tableSuperFields = superClazz.getDeclaredFields();        Field[] c = new Field[tableFields.length + tableSuperFields.length];        System.arraycopy(tableFields, 0, c, 0, tableFields.length);        System.arraycopy(tableSuperFields, 0, c, tableFields.length, tableSuperFields.length);        getSuperClassFields(c, superClazz);        return c;    }

输出结果：
