Jackson jr is a compact alternative to full Jackson Databind component. It implements a subset of functionality, for example for cases where:. And starting with 2. Jackson-jr also adds composer implementation that can be used to construct JSON output with builder-style API, but without necessarily having to build an in-memory representation: instead, it can directly use streaming-api for direct output. It is also possible to build actual in-memory JSON String or byte[] representation, if that is preferable. Main Jackson-jr artifact jackson-jr-objects itself is currently about kB in size, and only depends on Jackson Streaming API package. Combined size, for "all" jar, is bit over kB of which streaming API is about kB , for use cases where a single jar is preferred over more modular approach.

Spring is a framework of java that is used to build high-level, large-scale enterprise applications. And the most common thing we do in almost every application is transfer data between the front-end and back-end to the server. Supposedly, when we perform Update, Create, or any other operation that impacts changes in the Database then what happens is, data is sent in the form of a request from the client. And this request is received by the back end. It stores data in the form of plain-old-java-objects POJOs. So, if we were to convert data received or send in every request, there would be a lot of extra work and more code to do for programmers. See the diagram below. And vice-versa.

General data-binding package for Jackson 2. This project contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. Project is licensed under Apache License 2. While the original use case for Jackson was JSON data-binding, it can now be used to read content encoded in other data formats as well, as long as parser and generator implementations exist. Functionality of this package is contained in Java package com. Package also depends on jackson-core and jackson-annotations packages, but when using build tools like Maven or Gradle, dependencies are automatically included. You may, however, want to use jackson-bom to ensure compatible versions of dependencies. If not using build tool that can handle dependencies using project's pom. For use cases that do not automatically resolve dependencies from Maven repositories, you can still download jars from Central Maven repository. Jackson 2.

While the actual core components live under their own projects -- including the three core packages streaming , databind , annotations ; data format libraries; data type libraries; JAX-RS provider ; and a miscellaneous set of other extension modules -- this project act as the central hub for linking all the pieces together. Jackson suite has two major versions: 1. These two major versions use different Java packages and Maven artifact ids, so they are not mutually compatible, but can peacefully co-exist: a project can depend on both Jackson 1. This is by design and was chosen as the strategy to allow smoother migration from 1.
