README.md

This project is the main hub to all kinds of documentation related to the Jackson JSON Processor.

For your first steps in understanding how to use Jackson, following tutorials are good places to start:

• Baeldung Jackson JSON Tutorial
• Jackson in N minutes ( README for jackson-databind project)
• Jenkov.com Jackson Tutorial
• JournalDev JacksonTutorial
• LogicBig.com Jackson Tutorial
• Mkyong.com’s Jackson Tutorial (part of larger Java JSON Tutorials
• StudyTrails Jackson Introduction
• TedBlob Jackson Tutorial

JVM Languages beyond Java

(need links to Scala, Kotlin, Clojure tutorials, articles)

Documentation under Jackson GH projects

Jackson project hub has links to all active Jackson projects. These projects contain plenty of project-specific documentation, such as:

• Core Annotations
  • List of Jackson Core Annotations
  • On/off features, per-factory: JsonFactory.Features
  • On/off features, reading: StreamReadFeatures, JsonReadFeatures, JsonParser.Features.
  • On/off features, writing: StreamWriteFeatures, JsonWriteFeatures, JsonGenerator.Features
  • Databind Annotations
  • On/off features: DeserializationFeatures, SerializationFeatures, MapperFeatures.

  External (off-GitHub) documentation

  Blogs that regularly write about Jackson include:

  And here are good articles around the web:

  • General usage
    • Jackson JSON Tutorial by Eugen Paraschiv
    • Jackson — Installation at Jenkov.com
    • Processing JSON with Jackson (DZone)
    • Jackson jr for casual JSON processing

      The easiest ways to participate is to join one of Jackson mailing lists (Jackson google groups):

      • Jackson Announce: Announcement-only list for new Jackson releases, meetups and other events related to Jackson
      • Jackson User: List dedicated for discussion on Jackson usage
      • Jackson Dev: List for developers of Jackson core components and modules, discussing implementation details, API changes.

      There are other related lists and forums as well:

      • Smile Format Discussion: List for discussing details of the binary JSON format called Smile (see Smile Specificat
        ion)
      • Jackson Users is a Jackson-specific discussion forum for usage questions.

      Note that there are two major Jackson versions: 1.x (1.0 — 1.9) and 2.x (2.0 — 2.13). These versions can co-exist as they are located in different Java packages and use different jar naming and Maven group/artifact ids. But this means that you have to make sure that all components in use have matching major versions: specifically, Jackson 2.x code does NOT understand or support Jackson 1.x annotations, or vice versa.

      Minor versions (like 2.1 and 2.2) are backwards compatible with respect to public API: old code should work without recompilation, if (but only if) it relies on external API; public methods, annotations. When overriding internal functionality, we try hard to maintain backwards compatibility between adjacent minor versions; need for changes is indicated by deprecating internal methods. Recompilation is thus recommended when extending by sub-classing, for example.

      README.md

      This project contains core low-level incremental («streaming») parser and generator abstractions used by Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format. The core abstractions are not JSON specific, although naming does contain ‘JSON’ in many places, due to historical reasons. Only packages that specifically contain word ‘json’ are JSON-specific.

      This package is the base on which Jackson data-binding package builds on. It is licensed under Apache License 2.0.

      Alternate data format implementations (like Smile (binary JSON), XML, CSV, Protobuf, and CBOR) also build on this base package, implementing the core interfaces, making it possible to use standard data-binding package regardless of underlying data format.

      Project contains versions 2.0 and above: source code for earlier (1.x) versions can be found from Jackson-1 github repo.

      Functionality of this package is contained in Java package com.fasterxml.jackson.core .

      To use the package, you need to use following Maven dependency:

      dependency> groupId>com.fasterxml.jackson.coregroupId> artifactId>jackson-coreartifactId> version>$ version> dependency>

      or download jars from Maven repository or links on Wiki. Core jar is a functional OSGi bundle, with proper import/export declarations.

      Package has no external dependencies, except for testing (which uses JUnit ).

      For non-Maven use cases, you download jars from Central Maven repository.

      Core jar is also a functional OSGi bundle, with proper import/export declarations, so it can be use on OSGi container as is.

      Jackson 2.10 and above include module-info.class definitions so the jar is also a proper Java module (JPMS).

      Jackson 2.12 and above include additional Gradle 6 Module Metadata for version alignment with Gradle.

      Usage typically starts with creation of a reusable (and thread-safe, once configured) JsonFactory instance:

      // Builder-style since 2.10: JsonFactory factory = JsonFactory.builder() // configure, if necessary: .enable(JsonReadFeature.ALLOW_JAVA_COMMENTS) .build(); // older 2.x mechanism, still supported for 2.x JsonFactory factory = new JsonFactory(); // configure, if necessary: factory.enable(JsonReadFeature.ALLOW_JAVA_COMMENTS);

      Alternatively, you have an ObjectMapper (from Jackson Databind package) handy; if so, you can do:

      JsonFactory factory = objectMapper.getFactory();

      All reading is by using JsonParser (or its sub-classes, in case of data formats other than JSON), instance of which is constructed by JsonFactory .

      All writing is by using JsonGenerator (or its sub-classes, in case of data formats other than JSON), instance of which is constructed by JsonFactory :

      List is incomplete due to recent addition of compatibility checker.

      for information on Android SDK versions to Android Release names see Android version history

      Starting with Jackson 2.15, releases of this module will be SLSA compliant: see issue #844 for details.

      Release process is triggered by

      script which uses Maven Release plug-in under the hood (earlier release plug-in was directly invoked).

      Jackson components are supported by the Jackson community through mailing lists, Gitter forum, Github issues. See Participation, Contributing for full details.

      Differences from Jackson 1.x

      Project contains versions 2.0 and above: source code for the latest 1.x version (1.9.13) is available from FasterXML/jackson-1 repo (unmaintained).

      Note that the main differences compared to 1.0 core jar are:

      • Maven build instead of Ant
      • Annotations carved out to a separate package (that this package depends on)
      • Java package is now com.fasterxml.jackson.core (instead of org.codehaus.jackson )
      • Project Wiki has JavaDocs and links to downloadable artifacts
      • Jackson (portal) has links to all FasterXML-maintained «official» Jackson components
      • Jackson Docs is the portal/hub for all kinds of Jackson documentation
