FAQPage Schema

How do I build a Java microservice with Spring Boot 3.x?▼

Build a Spring Boot 3.x microservice by designing JPA entities, repository patterns, service layer logic, and REST controllers. The framework uses Java 21 and Spring Modulith to establish conventions for project structure, naming, and testing.

What is the best way to structure a modular monolith in Spring Boot?▼

Structure a modular monolith using Spring Modulith, which provides well-structured application modules. This approach integrates Spring Data JPA for data persistence while maintaining clear boundaries between different domain logic components.

How do I implement REST controllers and DTOs in a Spring Boot application?▼

Implement REST controllers and DTOs by following established conventions for mapping entities to data transfer objects. The skill covers service layer logic, mappers, and exception handling to ensure robust API endpoint implementation.

Does Spring Data JPA work with Spring Modulith for database interactions?▼

Spring Data JPA integrates seamlessly with Spring Modulith for efficient database interactions. It leverages Hibernate to manage data persistence within the modular monolith architecture, ensuring clean separation between modules.

Can I use this Spring Boot framework for e-commerce order management?▼

Yes, you can develop a new microservice for an e-commerce platform. The framework provides the necessary components for order management, including REST controllers, service logic, and JPA repositories.

What Java version is required for Spring Boot 3.x microservices?▼

Spring Boot 3.x microservices require Java 21. Using this version ensures compatibility with the latest Spring Boot features and the modular architecture provided by Spring Modulith.
