Customer-Records

Description

This is a simple Spring Boot Java application that parses a JSON list of those customer records and outputs a list of customers within 100 kilometers of a known geo coordinate and sorts them by their 'user_id' field in ascending order.

Implementation Details

• Easily-runnable Spring Boot application bootstrapped using Spring Initializr
• Application properties are configurable via YAML file
• Idiomatic Spring and Java code using
• JUnit integration
• Gradle application with easy dependency management
• Easily extensible following industry-standard technologies
• Calculations using standard Math libraries
• SCM using git and GitHub
• gitignore file to keep commits junk-free
• MIT license

Technologies Used

• Java 8
• Spring
• Spring Boot
• Spring Initializr
• git

Dependencies Used

• Hamcrest
• Jackson(ObjectMapper for parsing)

Future Areas of Improvements

• Make the properties configurable via command-line arguments and/or a GUI
• Improve application architecture following an industry-standard design pattern
• Improve test coverage and application robustness
• Use multiple branches for SCM(define branching strategy)
• Adopt a code style(e.g. Google Java Style Guide)
• Implement SLF4J logging
• Implement bare-bones CI/CD pipeline(Jenkins, SonarQube, etc)
• Configure mocking for tests
• Implement validation services at controller-level
• Make port easily configurable
• Accept datasource and latlong reference geocoord as fields in the request body and return a proper JSON object in the response
