Bu bölümde, JWE tabanlı kimlik doğrulama için gerekli olan bean’leri ve ayarları tanımlıyoruz:
application.properties veya application.yml üzerinden okur.AdminProperties
SecurityJwtConfig
SecurityConfig
JwtProperties
UserProperties
Bu bölümde, Spring Boot uygulamanızda JSON Web Encryption (JWE) tokenları oluşturmak, şifrelemek ve çözmek için gereken temel yardımcı sınıfları ve sabitleri tanımlıyoruz. Bu bileşenler şunları sağlar:
ROLE_ ön ekiyle rol isimlerini merkezileştirir.Bu yardımcılar, Spring Security ile durumsuz (stateless) JWE tabanlı bir kimlik doğrulama akışının temelini oluşturur.
AuthoritiesConstants
CookieBearerTokenResolver
CookieUtils
JweUtil
KeyUtils
SecurityUtils
Bu bölümde, aşağıdakileri gerçekleştirmek için gerekli REST controller ve DTO’ları tanımlıyoruz:
Bu bileşenler, login işlemi, token oluşturma, cookie yönetimi ve kaynak korumasını işleyerek stateless(durumsuz) kimlik doğrulama akışını tamamlar.
Bu bölümde, kullanıcı kimlik doğrulamasını, token oluşturmayı ve korunan kaynak erişimini yönetmek için REST controller ve DTO’ları oluşturuyoruz.
AuthController
HelloController
LoginRequestDTO
TokenDTO
./mvnw spring-boot:run # or gradle bootRun
Bu bölümde Endpoint Testi konusunu netleştirip uygulamada kullanacağınız temel noktaları özetliyoruz.
admin olarak giriş yapın ve Set-Cookie başlığından JWE tokeni yakalayın:
curl -i -X POST http://localhost:8080/api/auth/login \ -H "Content-Type: application/json" \ -d '{"username":"admin","password":"adminpass"}'
accessToken=<jwe-token> içerir{ "accessToken": "<jwe-token>", "tokenType": "Bearer", "accessTokenExpiresIn": 3600 }
cookie kullanarak hello endpointine erişin:
curl -b "accessToken=<jwe-token>" http://localhost:8080/api/hello
Veya Authorization başlığıyla:
curl -H "Authorization: Bearer <jwe-token>" http://localhost:8080/api/hello
admin-özel endpointine erişin:
curl -H "Authorization: Bearer <jwe-token>" http://localhost:8080/api/hello/admin
user olarak giriş yapın ve cookie’den JWE tokeni yakalayın:
curl -i -X POST http://localhost:8080/api/auth/login \ -H "Content-Type: application/json" \ -d '{"username":"user","password":"userpass"}'
accessToken=<jwe-token> içerircookie kullanarak hello endpointine erişin:
curl -b "accessToken=<jwe-token>" http://localhost:8080/api/hello
Authorization başlığıyla:
curl -H "Authorization: Bearer <jwe-token>" http://localhost:8080/api/hello
Admin endpointini deneyince (403 Forbidden döner):
curl -H "Authorization: Bearer <jwe-token>" http://localhost:8080/api/hello/admin # HTTP/1.1 403 Forbidden
Artık Spring Boot JWE Kimlik Doğrulama için üretim odaklı bir Spring Boot temeliniz var. Sonraki adımda ayarları kendi domainine uyarlayıp test ve gözlemlenebilirlik katmanını ekleyerek gerçek trafik altında doğrulayın.
