Project Assignment for CRED Internship 2020
Description - Geocoding is the process of converting the address like (Indiranagar, Bangalore) into geographic coordinates (like latitude: 12.978369 and longitude: 77.640836).
Example: When we enter: Bangalore
Result:
● Latitude: 12.971599
● Longitude: 77.594563
Framework - Spring Boot
Architecture - Model - View - Controller - Service
In Memory Caching - Redis
Library - Jackson , Jedis (Redis)
Flow of Control -
1. GeoCodeApplication (main function - [src/main/java/demo/Geocode1Application.java])
2. GeocodeController (Controller - [src/main/java/controller/GeocodeController.java])
3. GeocodeService (Service Layer - [src/main/java/service/GeocodeService.java])
*Data Transfer Object (DTO) - (geodata - model layer - [src/main/java/model/geodata.java])*
Caching -
As we know it is expensive to call the third party API repeatedly we need to reduce the number of API calls
to Google Geocode API. Hence, if we get multiple requests asking for geo coordinates for same city we need to
avoid network call to Google API and serve the request from cache.
API Contract
API - http://localhost:8080/apicall/geocode?locname=mysore
Response (for first call) - {"latitude":"12.2958104","longitude":"76.6393805","source":"API"}
Response (for subsequent calls) - {"latitude":"12.2958104","longitude":"76.6393805","source":"CACHE"}
*SOURCE field in API response is to identify the response source i.e API call or CACHE*
