Spring Boot has become a go-to framework for building scalable and efficient web applications, but security remains a critical concern for developers. One way to ensure the security of your Spring Boot application is by using Spring Security.
Spring Security is a powerful and flexible authentication and authorization framework that can be easily integrated into your Spring Boot application. In this article, we’ll explore the basics of Spring Security and how to use it to secure your Spring Boot applications.
What is Spring Security?
Spring Security is a framework that provides authentication and authorization functionality for your Spring Boot application. With Spring Security, you can easily secure your application by adding features such as authentication, authorization, and access control.
How to Use Spring Security
To use Spring Security in your Spring Boot application, you first need to add the Spring Security dependency to your pom.xml file:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>5.4.1</version>
</dependency>After adding the dependency, you need to configure Spring Security by creating a class that extends the WebSecurityConfigurerAdapter class:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/admin/**").hasRole("ADMIN")
.antMatchers("/user/**").hasRole("USER")
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("admin").password("{noop}password").roles("ADMIN")
.and()
.withUser("user").password("{noop}password").roles("USER");
}
}This class is responsible for configuring the security of your application. In the example above, we have configured our application to require authentication for all requests except the login page, and to authorize access based on the user’s role. We have also defined two users with their roles.

Common Security Features in Spring Security
Spring Security provides several features to help you secure your Spring Boot application. Some of the most common features include:
Authentication
Spring Security provides several authentication mechanisms, such as basic authentication, form-based authentication, and OAuth. You can choose the authentication mechanism that best fits your needs.
Authorization
Spring Security provides authorization mechanisms that allow you to control access to your application based on user roles or other criteria. You can use annotations or configuration to define access rules for your application.
Session Management
Spring Security provides session management features that allow you to manage user sessions, such as limiting the number of concurrent sessions, setting session timeouts, and invalidating sessions.
Conclusion
Securing your Spring Boot application is critical for protecting your users and data. With Spring Security, you can easily add authentication and authorization functionality to your application. In this article, we explored the basics of Spring Security and how to use it to secure your Spring Boot applications. By following the steps outlined in this article, you can ensure that your Spring Boot application is secure and reliable.
