Implementation of few functionalities of Redis

Built With

• Maven - Dependency Management
• JDK - Java™ Platform, Standard Edition Development Kit
• Spring Boot - Framework to ease the bootstrapping and development of new Spring Applications
• git - Free and Open-Source distributed version control system
• MongoDB - MongoDB is a general purpose, document-based, distributed database.

External Tools Used

• Postman - API Development Environment (Testing Docmentation)

To-Do

• RESTful Web Service (CRUD)
• Cache implementation
• LRU Cache Eviction Policy
• Security (Basic Authentication)
• Docker
• Spring Boot Admin
• Multithreaded operation(Thread Safe)

Running the application locally

packages

• models — to hold our entities;

• repositories — to communicate with the database;

• services — to hold our business logic;

• controllers — to listen to the client;

• resources/ - Contains all the static resources, templates and property files.

• resources/static - contains static resources such as css, js and images.

• resources/templates - contains server-side templates which are rendered by Spring.

• resources/application.properties - It contains application-wide properties. Spring reads the properties defined in this file to configure your application. You can define server’s default port, server’s context path, database URLs etc, in this file.
