Stack trace showed io.opentelemetry.exporter.internal.http.HttpExporter
sending to :4317 — Tempo on 4317 expects gRPC frames, gets HTTP, sends
RST. Switch endpoint to :4318 (Tempo OTLP HTTP receiver) and protocol to
http/protobuf so the SDK and Tempo speak the same protocol.
The gRPC config never took effect — Spring Boot SDK on micrometer-tracing-
otlp pulls in only the HTTP exporter by default; gRPC needs the explicit
opentelemetry-exporter-otlp jar.
K8s profile relied on shared/dev defaults for spring.datasource.url, but those
live inside the dev profile block — invisible when k8s profile is active.
Result: 'APPLICATION FAILED TO START — Failed to configure a DataSource'.
Move full datasource (and kafka/redis for projection-writer) wiring into the
k8s profile section. ENV vars come from Vault Agent injector
(ORDINIS_PG_USER/PASSWORD, ORDINIS_KAFKA_USER/PASSWORD, ORDINIS_REDIS_PASSWORD)
and chart-supplied ENV (ORDINIS_PG_HOST, ORDINIS_KAFKA_BOOTSTRAP, etc).
application.yml fallback URL was http://config-server.ordinis-dev:8888 — namespace
removed. Default now points to staging; SPRING_CLOUD_CONFIG_URI env still overrides
via Helm chart for any deployment.
ordinis-read-api модуль полностью реализован:
- OrdinisReadApiApplication main + EnableJpaRepositories/EntityScan
- LocaleNegotiator: RFC 7231 / Locale.LanguageRange.parse + Locale.lookup
по supported_locales справочника, fallback на default_locale,
поддержка Accept-Language: * (raw mode)
- LocaleAwareJsonFlattener: walk schema_json.properties, для x-localized
полей в data заменяет {locale:text} на string выбранной локали
с fallback на default_locale; recursive walk для nested objects
- RecordReadService: read с scope filtering + locale negotiation +
flatten, метрика ordinis_read_api_query_duration_seconds, scope
access enforcement (ScopeAccessDeniedException)
- DictionaryReadController: GET /api/v1/{name}/records/{businessKey}
и list, with @RequestHeader(Accept-Language), Content-Language
response header, Vary: Accept-Language; query param as_scope для
v1 (заменим на JWT scope claim позже)
- ReadApiExceptionHandler: 404 NoSuchElement, 403 ScopeAccessDenied,
400 IllegalArgument, 500 fallback
- application.yml profile-based: dev (port-forward, ddl-auto=none —
read-api не валидирует schema, это work writer/migrations), k8s
(Vault role ordinis-read-api, hikari read-only=true)
- logback-spring.xml: MDC включает 'locale' для Loki query
E2E (port 8081 параллельно с writer на 8080):
- GET MOSCOW-1 без Accept-Language → name=Москва-1, Content-Language: ru-RU
- GET MOSCOW-1 с Accept-Language: en-US → name=Moscow-1, Content-Language: en-US
- GET MOSCOW-1 с Accept-Language: fr,en-US;q=0.8,ru;q=0.5 → выбрал en-US (fr нет в supported)
- GET MOSCOW-1 с Accept-Language: * → raw {ru-RU,en-US}, _meta.locale=null
- GET list → массив с flatten для каждой записи
- GET NONEXISTENT → 404 not_found
- GET с as_scope=INTERNAL для PUBLIC записи → 403 scope_access_denied
- Remove spring-cloud-starter-bootstrap (deprecated в SC 2024.x; используем
spring.config.import вместо bootstrap context)
- Profile-based config: dev отключает Cloud Config + Vault + OTel + JPA
auto-config для standalone smoke testing; k8s profile подключает реальную
инфру (vault + config server)
- Dockerfile: COPY всех модулей parent pom их видит при reactor
- Уберём spring-boot-maven-plugin из read-api/projection-writer пока нет main
Validated:
- mvn install all 11 modules: BUILD SUCCESS
- Spring Boot стартует за 2.7s в dev profile
- /actuator/health UP, /actuator/prometheus отдаёт http_server_requests + jvm
- HelloController отвечает на GET /
