Please select your favorite engineering paradigm - Database First

Build RESTful, stateless, cloud-native, three-tier Docker-based architectural applications around type-safe, reusable, Debug-enabled SQL with databases as first-class citizens.

• Model First

Build RESTful, stateless, cloud-native, Docker-based, domain-driven applications with models, domains, and modules as first-class citizens around the revolutionary modern ORM.

Database First

Mjga is a completely redesigned, modern Java Web scaffolding built on a cloud-native philosophy with the following features:

• Containerized applications
• Components that can be loaded and unloaded
• Reputable unit testing
• Customizable meta-information

🍹 Custom Metadata

Containerization and Cloud-Native

1. Manage the entire lifecycle and configuration of the application via docker-compose.yml.
2. Customize all configurations through the .env file.
3. Deliver the entire application and its ecosystem components via docker-compose.yml.

Out-of-the-Box

1. Integrates common basic business functionalities such as authentication, permission management, and cache abstraction.
2. Code Check & Format, CI/CD Plugin, Docker Integration are all ready to use out of the box.
3. Comprehensive, design-driven, and environment-isolated unit testing.

Modernization

1. Modern: Technology choices align with the latest trends in the open-source community.
2. Configurable: Supports component selection on the web.
3. Best Practices: Every variable, function, module, and component is designed with best practices in mind.
4. Focused Boundaries: Stays within its functional boundaries, avoiding an "All In One" approach.

Quick Start

Confirm Environment Variables and Execution Permissions

# confirm .env and make sure process can use it
vim ${projectRoot}/.env
# confirm gradlew executable (unix-like OS)
chmod 755 ${projectRoot}/gradlew

Install Docker and Start Containers

cd ${projectRoot}
docker compose up -d database
docker compose build web
docker compose up -d web

(Optional) Start Locally

# confirm .env and gradle.properties make sure process can use it
vim ${projectRoot}/.env
docker compose up -d database
./gradlew jooqCodegen
${projectRoot}/gradlew bootRun

Common Tools

Compile the Project and Generate Table Mapping Objects and Data Access Layer Based on Database Schema

# generate schema mapping codes
./gradlew jooqCodegen
# output ->
# projectRootDir/build/generated-sources
# └── org.jooq.generated
#    └── tables # table mapping
#       ├── daos # Data Access Layer
#       ├── pojos # mapping dto
#       └── records # jooq query record

Global Code Formatting

./gradlew spotlessApply

Global Code Inspection

./gradlew pmdMain

Unit Testing

# will automatically generate jacocoTestReport
./gradlew test
