About

This is simple project to show how to create a basic API using Java 11 + Maven + Spring Boot + PostgrSQL + Flyway.

• Tutorials
  • https://www.codejava.net/frameworks/spring-boot/connect-to-postgresql-database-examples
  • https://www.techgeeknext.com/spring-boot/spring-boot-flyway-example

• Install sdkman (sdkman installs command line, https://sdkman.io/install)
  • curl -s "https://get.sdkman.io" | bash
  • source "$HOME/.sdkman/bin/sdkman-init.sh"
  • sdk version -> should print version
• Install spring: sdk install springboot
• Create new project: spring init --dependencies=web,data-jpa first-mvn

• To avoid database setup, add this to main: @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
• To connect to PostgrSQL: https://www.codejava.net/frameworks/spring-boot/connect-to-postgresql-database-examples

• Start server dev mode: mvn spring-boot:run
• Install pom stuff and skip tests: mvn clean install -DskipTests
• Only install dependencies: mvn dependency:resolve

• Controller (@RestController) -> Service (@Service) -> Dao (@Repository) -> Repo (@Repository) -> Entity (@Component)

• Controller advise should account for each type of error
• Response should returns JSONs (can return JSONs using Map<String, Object> body = new LinkedHashMap<>();) not strings.
