public EnumValueTypeHandler(Class<T> tClass) {
    if (tClass == null) {
        throw new IllegalArgumentException("参数类型不能为空");
    }
    if (BaseEnum.class.isAssignableFrom(tClass)) {
        // 如果实现了 BaseCodeEnum 则使用我们自定义的转换器
        typeHandler = new BaseEnumTypeHandler(tClass);
    } else {
        // 默认转换器 也可换成 EnumOrdinalTypeHandler
        typeHandler = new EnumTypeHandler(tClass);
