@Target({ANNOTATION_TYPE,METHOD,FIELD,PARAMETER}) @Retention(RUNTIME) public @interface JacksonInject
Jackson-specific annotation used for indicating that value of annotated property will be "injected", i.e. set based on value configured by ObjectMapper (usually on per-call basis). Usually property is not deserialized from JSON, although it is possible to have injected value as default and still allow optional override from JSON.

    Whether matching value from input (if any) is used for annotated property or not; if disabled (`OptBoolean.FALSE`), input value (if any) will be ignored; otherwise it will override injected value.

      String value
      Logical id of the value to inject; if not specified (or specified as empty String), will use id based on declared type of property.
      Returns:
      Logical id of the value to inject
      Default:
      ""
    • useInput

      OptBoolean useInput
      Whether matching value from input (if any) is used for annotated property or not; if disabled (`OptBoolean.FALSE`), input value (if any) will be ignored; otherwise it will override injected value.

      Default is `OptBoolean.DEFAULT`, which translates to `OptBoolean.TRUE`: this is for backwards compatibility (2.8 and earlier always allow binding input value).

      Returns:
      OptBoolean.TRUE to enable use of value from input instead of injected value, if available; OptBoolean.FALSE if injected value will always be used regardless of input.
