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.

Element Detail

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
