Spring Boot Architecture Templates

Enterprise Java and Spring Boot ecosystems rely on well-defined design patterns such as the Database-per-Service pattern, API Gateway pattern, and Event Sourcing. Rekhic provides dedicated blueprints for these topologies.

1. Enterprise Microservices Platform

This template models standard Spring Cloud patterns:

• API Gateway: Spring Cloud Gateway with token validation and rate limiting.
• Service Discovery: Eureka or HashiCorp Consul.
• Core Domain Services:
  • Order Service (Spring Boot + Spring Data JPA)
  • Customer Service (Spring Boot + PostgreSQL)
  • Inventory Service (Spring Boot + MongoDB)
• Database-per-Service: Each service owns its dedicated database, preventing shared database coupling.

2. Event-Driven Spring Kafka Pipeline

Models asynchronous event streaming:

• Producers: Spring Boot web services publishing business events via Spring for Apache Kafka.
• Event Broker: Multi-broker Apache Kafka cluster with partition topics (orders.created, payments.settled).
• Consumers: Worker services consuming topic partitions and maintaining localized read models.

3. Customizing Spring Blueprints

• Double-click connectors to specify communication protocols (e.g. REST JSON, gRPC Protobuf, Kafka Topic).
• Use the Auto Layout tool (LR or TB) to keep service tiers organized.
• Export to Markdown to automatically document all services and data stores for your engineering team wiki.
