onno-frameworkModel the business. Generate the rest.

Reusable Spring Boot starters that turn typed Java metadata — catalogs, documents, registers — into a database schema, a generic REST API, a server-driven UI, and an MCP tool surface for AI agents.

🗂️

Model the business

Catalogs, documents, tabular sections, accumulation/information registers, enumerations, and constants — all typed Java, compiler-checked. No tables or DTOs by hand.

⚙️

Generated, not hand-written

Schema, repositories, generated query services, the generic REST API, and migration history are all derived from the model at boot.

🖥️

Server-driven UI + MCP

A DivKit admin UI and a Model Context Protocol tool surface for AI agents, both generated from the same metadata and gated by the same RBAC.

Docs from the source of truth

The configuration reference is generated from the @ConfigurationProperties Javadoc — and the build fails if it ever drifts from the code.

Get started

Add the starter (Java 21, Spring Boot 3.4.x). Packages are su.onno.*; the Maven group is su.onno (open core, Apache-2.0).

xml

<dependency>
  <groupId>su.onno</groupId>
  <artifactId>onno-framework-starter</artifactId>
  <version>1.10.2</version>
</dependency>

Then read Architecture for how it fits together, or the handoff guide for building an ERP on the published libraries.

How these docs are built

This site mixes hand-written guides with reference generated from the source of truth, so the reference can't drift from the code:

Surface	Source of truth	How it's produced
Configuration properties	the `@ConfigurationProperties` Javadoc	`./gradlew generateConfigDocs` renders each starter's `spring-configuration-metadata.json`; `./gradlew check` fails if the committed file drifts
Java API (Javadoc)	the Java source	`./gradlew aggregateJavadoc`
Architecture, guides	maintained by hand	written Markdown

Changing a property? Edit its Javadoc and run ./gradlew generateConfigDocs — never hand-edit the table. See Keeping docs in sync.
