Enum Deserializer

This library smooths out differences in the way that different versions of jackson deserialize enums to ease the process of upgrading between versions. In jackson-databind-2.3.3, an int can be successfully deserialized into an enum while in jackson-databind-2.5.4 and newer, it can't. The custom deserializer handles the following cases:

  • Deserializing from int
    • If there is a @JsonCreator method that takes in int, use that
    • If there isn't and there is a single field in the enum of type int, match based on that
  • Deserializing from string
    • If the string parses to an int, parse it and use the int creation method instead
    • If there isn't and there is a @JsonCreator method that takes in string, use that
    • If there isn't match based on the name of the enum variants
