Foundations of Modern #Java Server Apps
summary
Modern Java microservices reuse the same underlying specs so HTTP endpoints, JSON, DI, validation, persistence, metrics and tracing are mostly standardized across frameworks. Examples: servlet engines like Tomcat, Jetty or Undertow and Vert.x/Grizzly; JSON via Jackson or Jakarta JSON-B; DI via CDI/Jakarta and JPA/Hibernate for persistence; security via JWT and metrics/tracing via Micrometer and MicroProfile Telemetry. Claim: those shared standards (Jakarta EE and MicroProfile) enable portability between runtimes, though the Jakarta namespace transition caused multi‑year upgrade pain.
