Introduction to Spring Security

In web development, security is a critical aspect that cannot be ignored. Today, we will dive into the world of Spring Security and understand its importance in ensuring a secure web application.

Spring Security is a powerful and highly customizable security framework for Java applications. It provides a wide range of security features, including authentication, authorization, and protection against common security vulnerabilities.

As a senior engineer with experience in Java, Spring Boot, and MySQL, you already have a solid foundation in building web applications. Spring Security will further enhance your skills and make you a better programmer by enabling you to implement robust security measures in your applications.

Let's start by writing a simple Java program to greet the world:

1  public class Main {
2    public static void main(String[] args) {
3        System.out.println("Hello, world!");
4    }
5  }

In the above code, we have a main method that simply prints "Hello, world!" to the console. This program demonstrates the basic structure of a Java application. As we progress through this lesson, we will explore more advanced topics and delve into the intricacies of Spring Security.
