Expired Contract Microservice

[cassidyxu]

Overview

Implements a microservice that processes expired contracts in the database. The microservice identifies expired contracts, determines if they qualify as a "hit," pays out their value to users, and marks them as archived.

Changes Made

Application.java

• Added a scheduled task to periodically check the contracts database for expired contracts.
• Logic to identify expired contracts based on expiration time and ensure they are not already marked as expired.
• Abstracted logic for identifying if a contract qualifies as a hit
• Implemented payout functionality to credit the contract value to the owner's balance if the contract qualifies as a hit
• Archived processed contracts by marking them as expired.

Contract.java

• added expired, expirationTime properties

ContractFactory.java

• updated fields to match new Contract model

Test Coverage

Created unit tests to verify the following:

• Tested the scheduled task to ensure expired contracts are processed correctly.
• Verified payouts to users for contracts marked as hits.
• Confirmed contracts are marked as expired after processing.
• Checked that contracts not meeting the criteria remain unaffected.
