* 1. Jackson 会先查找指定枚举类型对应的反序列化器（例如：GenderEnum 枚举类型，则是找 GenderEnum 枚举类型的对应反序列化器）；<br>
* 2. 如果找不到则开始查找 Enum 类型（所有枚举父类）的反序列化器；<br>
* 3. 如果都找不到则会采用默认的枚举反序列化器（它仅能根据枚举类型的 name、ordinal 来进行反序列化）。

* <p>
* 重写增强后：<br>
* 1. 同默认 1；<br>
* 2. 同默认 2；<br>
* 3. 如果也找不到 Enum 类型（所有枚举父类）的反序列化器，开始查找指定枚举类型的接口的反序列化器（例如：GenderEnum 枚举类型，则是找它的接口 BaseEnum 的反序列化器）；<br>
* 4. 同默认 3。
