Overview

This is a multi-module project that contains Jackson-based Jakarta-RS (*) providers for following data formats:

• JSON
• Smile (binary JSON)
• CBOR (another kind of binary JSON)
• XML
• YAML

Providers implement Jakarta-RS MessageBodyReader and MessageBodyWriter handlers for specific data formats. They also contain SPI settings for auto-registration.

(*) NOTE: Jakarta-RS is the package under jakarta.ws.rs, replacing older JAX-RS which lived under javax.ws.rs. For JAX-RS variant, see repo jackson-jaxrs-providers

Build

Usual Maven build like other Jackson repos, with one difference: requires JDK 11 to build (as opposed to JDK 8 for most other repos), as of Jackson 2.13

Status

Module is fully functional and considered mature.

Maven dependency

To use Jakarta-RS on Maven-based projects, use dependencies like:

<dependency>
  <groupId>com.fasterxml.jackson.jakarta.rs</groupId>
  <artifactId>jackson-jakarta-rs-json-provider</artifactId>
  <version>2.14.1</version>
</dependency>

(above is for JSON provider; modify appropriately for other providers)

Usage: registering providers

Due to auto-registration, it should be possible to simply add Maven dependency (or include jar if using other build systems) and let Jakarta-RS implementation discover provider. If this does not work you need to consult documentation of the Jakarta-RS implementation for details.

To use Jackson with Jersey see their documentation.

Annotations on resources

In addition to annotation value classes, it is also possible to use a subset of Jackson annotations with provider.

Here is a short list of supported annotations that work with all formats:

• @JsonView can be used to define active view for specific endpoint
• @JsonRootName can be used to specify alternate rootname; most often used with XML, but possibly with JSON as well.
• @JacksonAnnotationsInside meta-annotation may be used as a marker, to create "annotation bundles", similar to how they are used with value type annotations
• com.fasterxml.jackson.jakarta.rs.annotation.JacksonFeatures can be used with all provid to enable/disable
  • SerializationFeature / DeserializationFeature for data-binding configuration
  • JsonParser.Feature / JsonGenerator.Feature for low(er) level Streaming read/write options

In addition there are format-specific annotations that may be used:

• JSON has:
  • com.fasterxml.jackson.jakarta.rs.json.annotation.JSONP to define JSONP wrapping for serialized result
