Annotation Type JacksonInject



  • @Target(value={ANNOTATION_TYPE,METHOD,FIELD,PARAMETER})
     @Retention(value=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 possible to have injected value as default and still allow optional override from JSON.
    • Optional Element Summary

      Optional Elements 
      Modifier and Type Optional Element and Description
      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.
      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.

      • value

        public abstract 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

        public abstract 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.
        Since:
        2.9
        Default:
        com.fasterxml.jackson.annotation.OptBoolean.DEFAULT
