Learn how to implement Spring Data JPA pagination to prevent OutOfMemoryErrors, the critical difference between Page and Slice, and when to switch to keyset pagination for large datasets.
Stop dealing with partial database updates. Learn how to use Spring's @Transactional to ensure atomicity, avoid the common self-invocation proxy trap, and optimize connection usage.
Define a paginated entity in JHipster's JDL, import it to generate the full Spring Boot and front-end stack, and verify pagination via the X-Total-Count header — with rollback steps for bad imports.
JHipster's JDL lets you declare entities, relationships, and pagination in one versionable file and regenerate both tiers of a Spring Boot + Angular/React app. Here's a worked example, how to verify it, and the regeneration trade-off.
Learn how to implement Thymeleaf's Natural Templating to bridge the gap between static prototypes and dynamic Java server-side rendering while maintaining strict data boundaries.
Learn how to implement server-side pagination in Spring Data JPA using Pageable and PageRequest, and why choosing Slice over Page can significantly improve performance for large datasets.
Stop duplicating HTML across your templates. Learn how to use Thymeleaf Fragments and dynamic expressions to create reusable UI components that simplify maintenance.

In current Spring Boot and Spring Cloud releases, Spring Cloud LoadBalancer can resolve service instances through DNS, but the framework does not define its own DNS cache TTL or negative caching policy.
