Spring Boot Thymeleaf Example

This repository showcases a simple and modern Spring Boot app with Thymeleaf for managing books. Bootstrap is included as a WebJar for styling the page.

• using the Thymeleaf Layout Dialect, layout.html is applied as the page template
• an inputRow fragment in fragments/forms.html helps with form setup
• error.html is displayed for all application errors, including 404
• LocalDevConfig enables true hot reload – all changes are instantly visible in the browser during development

Create a Spring Boot application with Thymeleaf and your own database schema at Bootify.io. Choose from a wide range of settings to match your preferences and enable CRUD functions for your entities.

Development

Update your local database connection in application.properties or create your own application-local.properties file to override settings for development.

During development it is recommended to use the profile local. In IntelliJ -Dspring.profiles.active=local can be added in the VM options of the Run Configuration after enabling this property in "Modify options".

After starting the application it is accessible under localhost:8080.

Build

The application can be built using the following command:

mvnw clean package

Start your application with the following command - here with the profile production:

java -Dspring.profiles.active=production -jar ./target/thymeleaf-0.0.1-SNAPSHOT.jar

If required, a Docker image can be created with the Spring Boot plugin. Add SPRING_PROFILES_ACTIVE=production as environment variable when running the container.

mvnw spring-boot:build-image -Dspring-boot.build-image.imageName=io.bootify/thymeleaf
