How to Implement Role-Based Authentication in Spring Boot: Secure Your Application with Step-by-Step Code Examples

Role-based authentication is a common security requirement for many applications. In this article, we will explore how to implement role-based authentication using Spring Security and create a token for authenticated users. We will provide code examples to help you understand the implementation.

Example of implementing role-based authentication using Spring Security in Java:

Step-1 : Add Spring Security dependencies to your project’s pom.xml file:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>${spring-security.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>${spring-security.version}</version>
</dependency>

Step-2 :Create a configuration class that extends WebSecurityConfigurerAdapter and overrides the configure(HttpSecurity http) method to define the security rules for your application:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
    protected void configure(HttpSecurity http) throws Exception…
