📓 Common learnings
Learnt from: igorcampos-dev
PR: igorcampos-dev/spring-integrations-examples#21
File: spring-kafka-example/compose.yaml:30-32
Timestamp: 2025-07-22T01:30:57.054Z
Learning: User igorcampos-dev prefers to maintain environment parity between local development and production, avoiding development-specific configurations like ALLOW_PLAINTEXT_LISTENER even when they might provide clearer intent or safety nets.
Learnt from: igorcampos-dev
PR: igorcampos-dev/spring-integrations-examples#21
File: spring-kafka-example/README.md:12-17
Timestamp: 2025-07-22T01:35:41.406Z
Learning: User igorcampos-dev prefers minimal, high-level documentation in README files without detailed version specifications, choosing to keep tech stack information simple rather than adding precise version numbers.
Learnt from: igorcampos-dev
PR: igorcampos-dev/spring-integrations-examples#26
File: spring-kafka-example/compose.yaml:3-4
Timestamp: 2025-07-24T01:40:49.337Z
Learning: User igorcampos-dev requires hard-coded container names in Docker Compose files (like `container_name: app`) for CI pipeline validation purposes, which is a valid operational requirement that overrides the general best practice of avoiding hard-coded container names.

spring-kafka-example/pom.xml (4)
42-47: LGTM! Proper Lombok dependency configuration.The Lombok dependency is correctly configured as optional, which is appropriate since it's only needed at compile time.
69-80: LGTM! Correct annotation processor configuration.The Maven compiler plugin is properly configured with Lombok annotation processor path, enabling compile-time annotation processing.
86-93: LGTM! Appropriate exclusion of Lombok from final artifact.Correctly excludes Lombok from the packaged JAR since it's only needed during compilation.
25-25: Lombok version confirmed up-to-date and secureLombok 1.18.38 is the latest release (adds JDK 24 support) and has no known security vulnerabilities. Configuration can be approved as-is.

9-12: LGTM! Clean component structure with proper annotations.Good use of Lombok annotations and Spring component configuration for dependency injection.
spring-kafka-example/src/main/java/com/io/example/controller/ExampleController.java (1)
11-14: LGTM! Clean controller structure with proper annotations.Good use of Spring annotations and constructor injection pattern.
spring-kafka-example/src/main/java/com/io/example/consumer/KafkaConsumerServiceImpl.java (1)
18-22: LGTM! Well-structured Kafka listener implementation.The consumer method correctly uses configurable properties for topic and group ID, and properly handles message deserialization and logging.
spring-kafka-example/compose.yaml (1)
40-41: Kafka configuration aligns with single-node development setup.The configuration correctly sets
KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1andKAFKA_AUTO_CREATE_TOPICS_ENABLE: 'false'which is appropriate for development environments and aligns with the explicit topic creation strategy.
