/Maps-Directions

Primary LanguageJava

Locus Assignment: SDE

Running the application:

Dependencies: Java8+Maven The user can use controller to get the coordinates using the following endpoint

FYI: The following is a GET request

{BASE_URI}/directions?origin={startLat, startLong}&dest={endLat, endLog}

Heroku: https://maps-directions.herokuapp.com/directions?origin={startLat,startLong}&dest={endLat,endLog}

Eg: localhost:8080/directions?origin=12.93175,77.62872&dest=12.92662,77.63696

Heroku Eg: https://maps-directions.herokuapp.com/directions?origin=12.93175,77.62872&dest=12.92662,77.63696 (Include request-id in header for traceability)

The project is distributed in three sections:

  1. Configuring the maps SDK
  2. Getting the route using Directions API
  3. Playing with the legs.steps provided by google api to get the points

1 - Configuring the Directions API

  • Used JAVA SDK
  • Setting up API: src/main/java/com/locus/maps/directions/config/GeoApiContextConfiguration.java

2 - Getting the route using Directions API

  • Used standard Directions API as per Java SDK
  • File: src/main/java/com/locus/maps/directions/services/MapService.java

3 - Getting the list of coordinates

  • Used azimuth for calculating the bearing (for angling length)
  • Used radian distancing to find points
  • File: src/main/java/com/locus/maps/directions/services/DirectionService.java

Items added for production readiness

  • Used exception handling for Http Error code handling
  • Used log4j for logging
  • Configured RequestInterceptors along-with logback for logging request-id to all logs
  • Added Zipkin libraries for distributed tracing in cloud.
