job4j_grabber

Project - Job Vacancy Aggregator ✨

job4j_grabber is a project for automating the search and collection of job vacancies from websites based on specified criteria.
The application runs on a schedule and gathers all relevant vacancies for Java developers from a specified website (career.habr.com, section /vacancies/java_developer).
The collected data is stored in a PostgreSQL database, and access to the interface is provided through a REST API.
The execution schedule is configured in the settings file - app.properties.

Main Features

1. Vacancy Parsing:
   • Uses the jsoup library for HTML parsing and extracting job vacancy data;
   • The application automatically navigates through job listing pages, identifies Java-related positions, and saves them to the database.
2. Task Scheduling:
   • The application runs on a schedule using the Quartz Scheduler library, with periodicity defined in the app.properties file.
3. Data Storage:
   • Job vacancy data is stored in a relational PostgreSQL database using JDBC.
4. Data Access:
   • A REST API is implemented to provide access to the collected data via HTTP requests.
5. CI/CD:
   • GitHub Actions is used for automatic project builds and testing.
