JWT Auth Spring Boot Starter

The JWT Authorization Spring Boot Starter is designed to simplify the implementation of JSON Web Token (JWT) based authentication and authorization within Spring Boot applications. This starter provides a robust foundation for developers looking to secure their Spring Boot applications using JWT, a widely adopted industry standard for token-based authentication.

Features

• JWT-based authentication for secure REST APIs.
• Easy integration with Spring Boot applications.
• Based on Spring Security.

Getting Started

Dependency Setup

Add the dependency to your project.

Maven

<dependency>
    <groupId>dev.junsung</groupId>
    <artifactId>jwt-auth-spring-boot-starter</artifactId>
    <version>0.2.0</version>
</dependency>

Gradle

implementation("dev.junsung:jwt-auth-spring-boot-starter:0.2.0")

Usage

Step 1: Add Required Dependencies

Include the following dependencies in your build.gradle.kts file:

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-oauth2-resource-server")
    implementation("dev.junsung:jwt-auth-spring-boot-starter:0.2.0")
}

Step 2: Configure Security Filter Chain

Set up your SecurityFilterChain to include JWT authentication. Add authorizationServer configuration as shown below:

@Configuration
@EnableWebSecurity
class SecurityConfig {
    @Bean
    fun filterChain(http: HttpSecurity): SecurityFilterChain {
        return http
            // Additional security configurations...
            .oauth2ResourceServer { it.jwt {} }
            .authorizationServer { }
            .build()
    }
}

Additional Notes

• The JWT Auth Spring Boot Starter depends on Spring Security's OAuth2 components.
• Ensure you have the proper Spring Security configurations to protect your endpoints.
