Micronaut Framework and Microstream Java-Native Persistence Engine
Talkat JCON Europe 2023 · on Wednesday, 2023-06-21· at 10:00· Cinema Blackbox, Im Mediapark 1, 50670 Köln, Germany·
summary
Shows Micronaut integrated with MicroStream to build a Java REST CRUD demo (fruits) that persists a root object (FruitContainer with a List) into file storage, survives stop/start, and passes functional tests that start the server, save data, stop and restart to verify persistence. Uses Micronaut annotations like @StoreParams and a RootProvider helper, exposes a dev-only MicroStream REST GUI, integrates with Micrometer and the health endpoint, and can act as a JSR-107 cache (demo uses a 3s delay to prove caching).
