Spring Boot Jte Example

This example shows the usage of jte as a template engine for Spring Boot. It includes a table products that can be managed via the frontend (CRUD functions).

All jte templates are in src/main/jte, using layout.jte as a layout and components/inputRow.jte for forms. During development with the local profile, gg.jte.developmentMode=true is active, so that changes are immediately visible in the browser. In addition the Maven plugin jte-maven-plugin is configured – this precompiles all templates for the final jar and uses them by setting gg.jte.usePrecompiledTemplates=true.

Create your own personalized application with jte frontend on Bootify.io. Choose between Bootstrap and Tailwind CSS, add webpack, activate htmx, use Maven or Gradle and much more.

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/jte-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/jte
