Bus road challenge

Project structure

Project contains few packages:

• aspect
  • BusStationsControllerLoggingAspect - logging logic for BusStationsController
  • BusStationsFileValidatorLoggingAspect - logging logic for BusStationsFileValidator
  • FileOrientedGraphReaderLoggingAspect - logging logic for FileOrientedGraphReader
• controller
  • BusStationsController - main controller
  • ResponseExceptionHandler - controller advice
• dto
  • BusRoadResponse - response object which uses for BusStationsController. Contains dep_sid, arr_sid and direct_bus_road which says if road exist or not
  • ErrorResponse - response object which uses for controller advice. Contains error message
• exception
  • IllegalBusStationFileException - Custom exception which uses for file reading and validation
• graph
  • OrientedGraph - graph of bus stations which uses for road searching
  • OrientedGraphInitializer - graph initializer
• service
  • BFSGraphRoadFinder - component which uses BFS algorithm for searching a way between two vertexes
  • BusRoadCheckerImpl - main service which uses BFSGraphRoadFinder for inputted params and construct response
  • BusStationsFileValidator - component which validates inputted file with bus stations by validation rules which specified in properties
  • OrientedGraphFileReader - component which reads bus stations matrix and convert it into OrientedGraph
  • PropertyHolder - component which contains all application properties
