One occasionally requested feature for enums is that enum values be numbers (e.g. for flags) or strings (e.g. to compare with values in HTTP headers). That can be achieved by making those values properties of enum values. For example: ...
本文介绍了Java中生成随机数的方法和枚举的使用。生成随机数需通过Random类并指定最大值,如nextint(10)。枚举类型可通过enum定义,适用于有限个固定常量的场景,并能与switch语句结合使用。

I actually had setFAIL_ON_NUMBERS_FOR_ENUMStotrueto skip evaluating ints as the index of the enum value. But the code crashes anyway. I see that the problem lies inEnumDeserializer.deserialize(). For Strings, it looks up the enum value, as given by@JsonValue. For ints, it looks up...
