# Create Spring Boot Kotlin project prompt - Please make sure you have the following software installed on your system: - Java 21 - Docker - Docker Compose - If you need to custom the project name, please change the `artifactId` and the `packageName` in [download-spring-boot-project-template](#download-spring-boot-project-template) - If you need to update the Spring Boot version, please change the `bootVersion` in [download-spring-boot-project-template](#download-spring-boot-project-template) ## Check Java version - Run following command in terminal and check the version of Java ```shell java -version ``` ## Download Spring Boot project template - Run following command in terminal to download a Spring Boot project template ```shell curl https://start.spring.io/starter.zip \ -d artifactId=${input:projectName:demo-kotlin} \ -d bootVersion=3.4.5 \ -d dependencies=configuration-processor,webflux,data-r2dbc,postgresql,data-redis-reactive,data-mongodb-reactive,validation,cache,testcontainers \ -d javaVersion=21 \ -d language=kotlin \ -d packageName=com.example \ -d packaging=jar \ -d type=gradle-project-kotlin \ -o starter.zip ``` ## Unzip the downloaded file - Run following command in terminal to unzip the downloaded file ```shell unzip starter.zip -d ./${input:projectName:demo-kotlin} ``` ## Remove the downloaded zip file - Run following command in terminal to delete the downloaded zip file ```shell rm -f starter.zip ``` ## Unzip the downloaded file - Run following command in terminal to unzip the downloaded file ```shell unzip starter.zip -d ./${input:projectName:demo-kotlin} ``` ## Add additional dependencies - Insert `springdoc-openapi-starter-webmvc-ui` and `archunit-junit5` dependency into `build.gradle.kts` file ```gradle.kts dependencies { implementation("org.springdoc:springdoc-openapi-starter-webflux-ui:2.8.6") testImplementation("com.tngtech.archunit:archunit-junit5:1.2.1") } ``` - Insert SpringDoc configurations into `application.properties` file ```properties # SpringDoc configurations springdoc.swagger-ui.doc-expansion=none springdoc.swagger-ui.operations-sorter=alpha springdoc.swagger-ui.tags-sorter=alpha ``` - Insert Redis configurations into `application.properties` file ```properties # Redis configurations spring.data.redis.host=localhost spring.data.redis.port=6379 spring.data.redis.password=rootroot ``` - Insert R2DBC configurations into `application.properties` file ```properties # R2DBC configurations spring.r2dbc.url=r2dbc:postgresql://localhost:5432/postgres spring.r2dbc.username=postgres spring.r2dbc.password=rootroot spring.sql.init.mode=always spring.sql.init.platform=postgres spring.sql.init.continue-on-error=true ``` - Insert MongoDB configurations into `application.properties` file ```properties # MongoDB configurations spring.data.mongodb.host=localhost spring.data.mongodb.port=27017 spring.data.mongodb.authentication-database=admin spring.data.mongodb.username=root spring.data.mongodb.password=rootroot spring.data.mongodb.database=test ``` - Create `docker-compose.yaml` at project root and add following services: `redis:6`, `postgresql:17` and `mongo:8`. - redis service should have - password `rootroot` - mapping port 6379 to 6379 - mounting volume `./redis_data` to `/data` - postgresql service should have - password `rootroot` - mapping port 5432 to 5432 - mounting volume `./postgres_data` to `/var/lib/postgresql/data` - mongo service should have - initdb root username `root` - initdb root password `rootroot` - mapping port 27017 to 27017 - mounting volume `./mongo_data` to `/data/db` - Insert `redis_data`, `postgres_data` and `mongo_data` directories in `.gitignore` file - Run gradle clean test command to check if the project is working ```shell ./gradlew clean test ``` - (Optional) `docker-compose up -d` to start the services, `./gradlew spring-boot:run` to run the Spring Boot project, `docker-compose rm -sf` to stop the services. Let's do this step by step.
