API

This is the REST Api for ArjMart. It uses Jersey (JAX-RS) as its framework. The backend is a JDBC Database (currently MySQL but abstracted away behind HikariCP).

Running this yourself

First and foremost, add your database info to 'src/jdbc.properties'. The application will not start without that. Second, compile a war file and deploy it to your application server of choice. Third, sit back and enjoy a fully working E-Commerce API system.

Technologies

• JAX-RS
• Jackson JSON
• JDBC (MySQL)
• HikariCP
• HK2 Dependency Injection
• Slf4j (logging framework)
• JMS (ActiveMQ backend)

Best Practices

• All database logic is abstracted away into DAOs
• HK2 Dependency Injection encapsulates logic into interfaces for DAOs and implementations
• Connections to database are pooled for maximum performance
• Authentication and authorization logic are abstracted into a filter and used with simple annotations
• Exception handling is delegated to dedicated ExceptionMappers so resource methods only handle best-case scenarios

Unit Testing

• Everything is very testable. DAOs can be replaced with mocks to test resource methods, and Jersey can handle everything else. DAOs themselves can be tested via giving them a mocked ConnectionFactory with connections to a fake in-memory database.
