This is a sample repository to demonstrate some of the common anti-patterns in Spring Boot REST API development.

• Not following REST API conventions
  • No proper URL structure
  • Not returning proper HTTP status code
• Using Field Injection
• Not using pagination for collection type resources
• Not using request-specific payload structures (Using entity types as payloads)
• Using JPA DDL auto generation
• Misusing Spring Data JPA derived-query method names
• Loading entire entities and using only a small subset of fields
• Using JPA that results in N+1 Select problems
• Not implementing proper Exception Handling
• Using @SpringBootTest for testing slices (controller, repository)
• Testing with in-memory database
• Not using proper package structure
  • package-by-layer
  • package-by-feature
  • package-by-component
  • Hexagonal
  • Ports & Adapters
  • Clean Code
