  • Or in Angular UI
  • Customer Database console: http://localhost:5051/h2-console/ - 'jdbc:h2:mem:customerdb'
• Item Service can be tested:
  • Either using API Gateway: http://localhost:5555/itemsApi/swagger-ui.html
  • Or using direct URL: http://localhost:5052/swagger-ui.html
  • Or in Angular UI
  • Item Database console: http://localhost:5052/h2-console/ - 'jdbc:h2:mem:itemdb'
