Master AWS deployment: Build & Deploy a Java full stack App

Configure JPA repositories for user and task entities, and define methods like find by user name, find by role, and find by completed status, with JPA auto-generating queries.

Implement a custom user details service that loads a user by username. Retrieve the user from the repository, throw not found if missing, and build the auth user details.

Implement an auth filter that intercepts requests, extracts a bearer token from the authorization header, validates the JWT, loads user details, and sets the security context before proceeding.

Create a React app for the task front end, install react-router-dom, react-date-picker, and Axios, then run npm start and organize files into API, guard, common, and pages.

Develop an api service class to handle http requests, token-based authentication, and task management calls in a React app, including register, login, and protected routes.

Launch an EC2 instance on AWS to host your backend by creating a new key pair, selecting Amazon Linux, and using the free tier for deployment.

Package the generated jar and deploy it to the cloud server using scp with a pem key, creating a projects directory to host the file.

Fix routing by adding a fallback url that redirects unknown paths to the tasks page and corrects the navigation bar router link, improving navigation and user experience.

Deploy a spring boot task service to an AWS server by moving the jar, running java -jar on port 3030, and using screen to keep it alive with log redirection.
