A collection of 10 practical best practices for Spring Boot development drawn from real-world experience. Topics covered include understanding Spring Boot's auto-configuration, leveraging built-in customization via properties instead of manual bean definitions, avoiding unnecessary starters, preferring constructor-based dependency injection, using TestContainers for integration tests with real databases, using test slice annotations like @WebMvcTest and @DataJpaTest to speed up tests, adopting database migration tools like Flyway or Liquibase, using off-the-shelf security solutions, organizing configuration into dedicated classes, and creating custom Spring Boot starters to reduce boilerplate across projects.
