spring-kafka-microservice
This is a repository for building a Spring Boot microservice using NetflixOSS and Apache Kafka.
Read the complete blog here - https://crunchytechbytz.wordpress.com/2018/02/09/microservice-with-apache-kafka-netflix-oss/
Prerequisite
- Java 1.8
- Kafka
- docker
Service Registry (Eureka)
- Build/Run
- mvn clean install
- java –jar target/EurekaServer-0.0.1-SNAPSHOT.jar
- Check
Config Server
- Update properties
- SET search-paths & git-url in /spring-kafka-microservice/ConfigServer/src/main/resources/application.yml
- SET USERNAME in spring-kafka-microservice/EmailServiceConfigProperties/email-service/dev/email-service.yml
- SET PASSWORD in spring-kafka-microservice/EmailServiceConfigProperties/email-service/dev/email-service.yml
- Build/Run
- mvn clean install
- java –jar target/ConfigServer-0.0.1-SNAPSHOT.jar
- Check
User Service
- Run
- mvn clean install
- java -jar target/UserAccount-0.0.1-SNAPSHOT.jar
- Check
- http://localhost:8081/member -- expect 0 records returned
Email service
- Run
- mvn clean install
- java -jar target/EmailService-0.0.1-SNAPSHOT.jar
Test Microservice
Once each micro service is setup and started correctly, you can test the complete flow by
- Create a new user by calling url – POST http://localhost:8081/register
- Verify that the new user is created.
- You can also verify the user by calling – GET http://localhost:8081/member
- Verify that registration success email was received at your email address
Deploying micro service in docker container
The same microservice can also be deployed in docker containers and I have published a blog on same here - https://crunchytechbytz.wordpress.com/2018/02/25/deploy-a-spring-boot-microservice-with-netflix-oss-stack-in-docker-container/
Simialry, if someone needs to refer to any help on installing Apache Kafka in docker container then they can refer here - https://crunchytechbytz.wordpress.com/2018/01/28/install-apache-kafka-in-docker-container/
