1. Spring Framework

Fundamental Concepts

Spring is an open - source framework that provides a comprehensive programming and configuration model for modern Java - based enterprise applications. It follows the Inversion of Control (IoC) and Aspect - Oriented Programming (AOP) principles. IoC allows objects to have their dependencies injected rather than creating them directly, while AOP enables modularization of cross - cutting concerns like logging and security.

Usage Methods

To use Spring in a web application, you first need to add the Spring dependencies to your project. If you are using Maven, you can add the following dependencies to your pom.xml:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring - webmvc</artifactId>
    <version>5.3.18</version>
</dependency>

Here is a simple example of a Spring MVC controller:

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {
    @RequestMapping("/hello")
    @ResponseBody
    public String hello() {
        return "Hello, Spring!";
    }
}

Common Practices

  • Use Spring Boot for quick project setup and embedded server support.
  • Follow the MVC pattern for clear separation of concerns.

Best Practices

  • Use dependency injection properly to improve testability.
  • Leverage Spring’s security features to protect your application.

2. JavaServer Faces (JSF)

Fundamental Concepts

JSF is a Java web application framework that simplifies the development of user interfaces for web applications. It is a component - based framework, where the UI is composed of reusable components. It provides a set of standard UI components and a lifecycle model for handling user interactions.

Usage Methods

To use JSF, you need to add the JSF dependencies to your project. For Maven:

<dependency>
    <groupId>javax.faces</groupId>

</dependency>

Here is a simple JSF page example (index.xhtml):

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html">
<h:head>
    <title>JSF Example</title>
</h:head>
<h:body>
    <h:form>
        <h:outputText value="Hello, JSF!" />
    </h:form>
</h:body>
</html>

Common Practices
