This project is a simple REST application for serving a blog. It uses Spring Boot, Spring Data JPA and some other helper libraries.

Currently, application can only serve blog post details by executing GET request at /posts/{id}, where {id} is a post identifier.

Your task is to add comments feature. The application should be able to serve two new kinds of requests:

• POST at /posts/{id}/comments which should:

  • Save a new comment with current date and time for post with passed {id}
  • Return 201 Created if comment is created successfully for post with passed {id}
  • Return 404 Not Found if post with passed {id} does not exist

• GET at /posts/{id}/comments which should:

  • Return all comments sorted by creation date in descending order for a post with passed {id}
  • Return empty list if a post with passed {id} does not exists or when it does not contain any comments

There is a service class CommentService that you should implement. See contents of that class to see detailed requirements. For each method, there is a javadoc comment that describes expected behavior.

There are some tests that are currently failing and your solution should satisfy these tests requirements. Remember that provided tests verify the functional correctness, however, you should remember to fulfill all best practices as well.

Feel free to create new and modify existing files. You can add some new dependencies if you will, to do so just modify appropriate pom.xml. Do not change unit tests, however.

Please follow conventions used in this project.
