REST Based Webservice

RESTful web service which handles POST and GET methods.

1. POST: Stores the received JSON data to a file
2. GET: Sends the requested data, if available, to the user in JSON format.
3. Error scenarios are handled by sending appropriate HTTP error codes.

Environment and Additional Libraries Used

• Java 8
• Maven
• Spark Java http://sparkjava.com/
• Gson
• Lombok https://projectlombok.org/
• log4j http://logging.apache.org/log4j/1.2/
• slf4j 1.7.25 https://www.slf4j.org/

Running the Webservice

1. Clone the project.
2. In command line, navigate to REST-Web-Service/ and execute the following to start the service

java -jar RestWebService.jar

3. Send the POST or GET requests (use url http://localhost:5000/) - I used Postman for this.
4. The projects will be stored in the file "projects.txt" in the same location as the jar
5. The server logs will be stored in the file "web_service_logs.txt" in the same location as the jar

Testing the Webservice Using Postman

• Import the file "TestRESTWebService.postman_collection.json" to Postman (https://www.getpostman.com/). This will create a "TestRESTWebService" folder in Postman.
• Keep the server running.
