GetFit-Spring-Native
GetFit-Spring-Native is a sample PoC (Proof of Concept) Spring Native console-based application designed to parse exercise entries found in a text file and convert them into a CSV file for analysis.
When taking a new technology for a test drive, a sample application is a developer's best friend.
This small application and the programming challenge it solves, presents a way to do just that.
Technologies Used
- Spring Native
- Spring Boot
- Gradle 7.x
- JUnit 5
- Java OpenJDK 17
- GraalVM CE with Native Image Support
Application Background
As part of their terms of service, many of today's wearable and smartphone based fitness trackers require users to upload metrics to third-party cloud services for analysis.
However, some users have privacy concerns with publicly sharing this data. Reference: USA today article
The GetFit Sample Spring Native application reads as input a local text file containing user log entries exercise details data and converts it into a CSV file.
Sample Input Text File Format
Each exercise log entry is separated by a blank line. Record entries are all optional and can appear in any order. The application is capable of normalizing this data and will report errors to the user during parsing in the event it reads record entries that cannot be parsed.
Usage
getfit --inFile fileName
CSV Output
The output CSV file will be generated to the same directory that the input file exists.
It conforms to the CSV Format standardization rules found in RFC-4180
