jsonschema2pojo generates Java types from JSON Schema (or example JSON) and can annotate those types for data-binding with Jackson 2.x, Jackson 3.x, or Gson.
Try jsonschema2pojo online
or brew install jsonschema2pojo
You can use jsonschema2pojo as a Maven plugin, a command line utility, a Gradle plugin or embedded within your own Java app. The Getting Started guide will show you how.
A very simple Maven example:

repositories {
mavenCentral()
}
jsonSchema2Pojo {
targetPackage = 'com.example'
}
id "java"
id "org.jsonschema2pojo" version "1.3.3"
}
repositories {

}
jsonSchema2Pojo {
targetPackage = 'com.example'
}
