Minimal Integration

This page explains how to start a new Geelato-based project from scratch and keep the first integration focused on the framework foundation instead of platform-heavy extensions.

  1. Import geelato-framework-bom
  2. Add geelato-framework-starter
  3. Start from geelato-sample-quickstart
  4. Verify the primary datasource, JdbcTemplate, Dao, ORM, and one sample endpoint
  5. Move to geelato-app-scaffold once the project needs ready-to-use backend services
  6. Add runtime, designer, or business extensions only after the minimal path is stable

Minimal Dependency Rule​

At the beginning, keep only:

  • geelato-framework-bom
  • geelato-framework-starter
  • one primary datasource driver
  • a Spring Boot web application

Do not start with:

  • platform-specific upload runtime
  • designer-side metadata governance
  • message, market, schedule, or similar extensions
  • heavy platform capabilities that require extra middleware

Minimal Configuration Surface​

The current starter wiring is triggered by spring.datasource.primary.jdbc-url, and it creates these default beans:

  • primaryDataSource
  • primaryJdbcTemplate
  • primaryDao
  • dbGenerateDao

If spring.datasource.secondary.jdbc-url is also provided, the secondary beans are created as well.

The official minimal sample is geelato-sample-quickstart, which uses:

  • geelato-framework-starter
  • an in-memory H2 datasource
  • geelato.orm.dao-bean-name=dynamicDao
  • JTA and Seata proxy disabled by default

Its purpose is to prove that the framework foundation can be consumed independently.

When to Switch to the Scaffold​

If the project already needs these baseline backend capabilities:

  • login
  • MQL
  • organization and user management
  • dictionary
  • upload

do not keep growing the minimal sample. Move to:

  • geelato-app-scaffold

Its role is to be the official ready-to-start scaffold, not the minimal verification sample.

Minimal Success Criteria​

The shortest successful path should verify:

  • the application starts
  • the primary datasource is available
  • JdbcTemplate and Dao can be injected
  • ORM auto-configuration is active
  • one runtime endpoint can be called
