jsonschema2pojo generates Java types from JSON Schema (or example JSON) and can annotate those types for data-binding with Jackson 2.x or Gson.

You can use jsonschema2pojo as a Maven plugin, an Ant task, 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:

<plugin>
    <groupId>org.jsonschema2pojo</groupId>
    <artifactId>jsonschema2pojo-maven-plugin</artifactId>
    <version>1.2.1</version>
    <configuration>
        <sourceDirectory>${basedir}/src/main/resources/schema</sourceDirectory>
        <targetPackage>com.example.types</targetPackage>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
</plugin>

A very simple Gradle example:

plugins {
  id "java"
  id "org.jsonschema2pojo" version "1.2.1"
}

repositories {
  mavenCentral()
}

dependencies {
  implementation 'com.fasterxml.jackson.core:jackson-databind:2.15.2'
}

jsonSchema2Pojo {
  targetPackage = 'com.example'
}
