Jackson Data Binding Source Code

Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

  • Jackson Data Binding module allows you to converts JSON to and from POJO (Plain Old Java Object) using property accessor or using annotations.
  • Jackson Databind Source Code files are provided in the source packge (jackson-databind-2.14.0-sources.jar). You can download it at Jackson Maven Website.
