• helpful classes
• design patterns I was using
• some best practices I wanted to share
• Examples of new features introduced in java 11/12/13/14/15

• JUnit5
• GeoTools

• First, run SpringBootApp with gradle (in order to have all git information)
• actuator
  • with build info in /info (http://localhost:8080/actuator/info)
  • it displays all endpoints in /actuator (http://localhost:8080/actuator)
  • display all health details (http://localhost:8080/actuator/health)
  • display git information (http://localhost:8080/actuator/info)
• springdoc-openapi (replaces swagger)
  • http://localhost:8080/v3/api-docs : returns json doc
  • http://localhost:8080/swagger-ui.html/ : returns pretty UI
• Custom failure analyzer (see MyFailureAnalyzerController)
• Basic Spring Boot Security example (http://localhost:8080/requires-login)
• Basic test of lombok
• Basic test of Selma mapper
  • selma is a fast mapper (https://javaetmoi.com/2015/09/benchmark-frameworks-java-mapping-objet)
  • selma is using annotation processing
• FeignClient: enables to easily write web service clients
  • It uses Spring Cloud OpenFeign
  • It connects to a fake API : https://instantwebtools.net/fake-rest-api
  • http://localhost:8080/airlines/1
  • http://localhost:8080/passengers?page=1&size=10
• ControllerAdvice: Custom exception handling
  • http://localhost:8080/throwexception : a generic exception has been caught
  • http://localhost:8080/thrownfe : a NumberFormatException but it is caught by its parent class (IllegalArgumentException)
  • http://localhost:8080/throwfeign : Feign was calling a non existing end point, ErrorDecoder is handling cases
  • http://localhost:8080/throwlocalized : The returned exception is localized
