Java full-stack refers to web developers that use Java to develop the entire technology. This means they use Javascript for front-end programming and Java for back-end programming. There are many steps to web development and many tools that go along with each step.
Technologies commonly used include:
Front-end: HTML, CSS, JavaScript, Angular, React.
Back-end: Java, Spring Boot, Hibernate, RESTful APIs.
Databases: MySQL, MongoDB, PostgreSQL.
Tools: Maven, Git, Jenkins, Docker.
Spring Boot is a framework that simplifies Java-based web applications. It is popular because it reduces the amount of configuration needed to set up and run an application, making it easier to create stand-alone, production-ready applications.
RESTful APIs are web services that use HTTP methods to communicate between a client and server. In Java, RESTful APIs are often implemented using frameworks like Spring Boot with annotations like @GetMapping, @PostMapping, etc.
Model: Represents the data layer, interacts with the database.
View: Represents the UI layer, displaying data to the user.
Controller: Handles user input, communicates between the model and the view.
Hibernate is an ORM (Object-Relational Mapping) framework used in Java to map objects to database tables. It simplifies database operations by allowing developers to write database queries in Java, abstracting away SQL.
GET: Retrieves data from the server and is idempotent (no side effects).
POST: Submits data to the server, often creating or updating resources.
Docker is a containerization tool that allows developers to package their application and its dependencies into a container, ensuring that the application runs the same in all environments (development, testing, production).
Maven is a build automation tool used in Java projects for managing dependencies, building projects, and packaging code into deployable formats like JAR or WAR.
Microservice architecture breaks down a large application into smaller, independently deployable services that communicate with each other over HTTP or messaging systems. Each microservice is responsible for a specific business function.
Angular: A full-fledged MVC framework developed by Google, offering two-way data binding.
React: A JavaScript library developed by Facebook, offering one-way data binding, focused on building reusable UI components.
Dependency Injection (DI) is a design pattern in Spring where objects are automatically injected into a class, avoiding the need for manual instantiation. It promotes loose coupling and enhances testability.
JWT (JSON Web Token) is a compact, URL-safe token used to securely transmit information between parties. In Java Full Stack, it is commonly used for authentication and authorization of users in web applications.
NoSQL databases (like MongoDB) store data in formats such as key-value pairs, documents, or graphs and are scalable horizontally.
SQL databases (like MySQL) store data in relational tables and are vertically scalable.
Session: Stored on the server and used to maintain user state across requests.
Cookie: Stored on the client (browser) and can be used for tracking or remembering user preferences.
These annotations are used to define Spring-managed beans:
@Component: Generic stereotype for a Spring bean.
@Service: Denotes a service layer component.
@Repository: Marks a Data Access Object (DAO) that handles database operations.
@RestController is a specialized version of the @Controller annotation in Spring Boot. It indicates that the controller methods will return JSON/XML responses instead of rendering a view. It is commonly used to build RESTful APIs.
CI is a practice where developers integrate code into a shared repository multiple times a day. Each integration is automatically tested using tools like Jenkins to ensure the application functions as expected.
A Promise in JavaScript represents an operation that hasn’t completed yet but is expected to in the future. It is used in asynchronous programming to handle the eventual success or failure of an operation, such as fetching data from an API.
Use caching mechanisms like Redis or EhCache to reduce database load.
Optimize database queries using indexing or query tuning.
Minimize HTTP requests by bundling JavaScript and CSS files.
Enable lazy loading for images and heavy resources.
Implement pagination for large data sets to reduce server load.
Java is used on the back-end for server-side development. With frameworks like Spring Boot, it enables developers to build robust, scalable, and secure web applications.
