    For containerizing Spring Boot applications to ensure consistency across environments.

    Kubernetes

    Manages containerized Spring Boot applications in production.

    Heroku/AWS Elastic Beanstalk

    Simplified platforms for deploying Spring Boot applications to the cloud.

    8. Version Control#

    • Git A must-have for version control, often integrated with platforms like GitHub, GitLab, or Bitbucket.

    9. Productivity Boosters#

    Lombok

    Reduces boilerplate code by generating getters, setters, and constructors at compile-time.

    ModelMapper/MapStruct

    Simplifies mapping between DTOs and entities.

    10. Security Tools#

    Spring Security

    Handles authentication and authorization.

    OWASP Dependency-Check

    Ensures dependencies are secure and free from known vulnerabilities.

    11. Other Useful Tools#

    REST Client (for HTTP Requests in Spring Boot)

    Use Spring’s WebClient or other libraries like Apache HttpClient.

    Thymeleaf/Freemarker

    Templates for building server-side rendered views.

    DevTools

    A Spring Boot dependency that simplifies live reloading during development.
