Spring Security OAuth2 Client 使用 client_credentials 模式获取 AccessToken 和 RefreshToken

Spring Security OAuth2 Spring Boot About 1,860 words

说明

适用于所有OAuth2协议的IDP,本文以Keycloak为例。

添加依赖

本人以Spring Boot 3.1.5为例。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>

添加配置

spring:
  security:
    oauth2:
      client:
        registration:
          keycloak:
            client-id: my-client
            client-secret: 
            authorization-grant-type: client_credentials
            scope:
              - openid
        provider:
          keycloak:
            issuer-uri: http://localhost:8080/realms/my-realm

获取 Token

@Autowired
private ClientRegistrationRepository clientRegistrationRepository;

ClientRegistration keycloak = clientRegistrationRepository.findByRegistrationId("keycloak");
DefaultClientCredentialsTokenResponseClient client = new DefaultClientCredentialsTokenResponseClient();
OAuth2ClientCredentialsGrantRequest request = new OAuth2ClientCredentialsGrantRequest(keycloak);
OAuth2AccessTokenResponse tokenResponse = client.getTokenResponse(request);
String accessToken = tokenResponse.getAccessToken().getTokenValue();
String refreshToken = tokenResponse.getRefreshToken().getTokenValue();

刷新 Token

@Autowired
private ClientRegistrationRepository clientRegistrationRepository;

String refreshToken = "xxx";
DefaultRefreshTokenTokenResponseClient client = new DefaultRefreshTokenTokenResponseClient();
ClientRegistration keycloak = clientRegistrationRepository.findByRegistrationId("keycloak");
OAuth2AccessToken oAuth2AccessToken = new OAuth2AccessToken(OAuth2AccessToken.TokenType.BEARER, "1", null, null);
OAuth2RefreshToken oAuth2RefreshToken = new OAuth2RefreshToken(refreshToken, null);
OAuth2RefreshTokenGrantRequest request = new OAuth2RefreshTokenGrantRequest(keycloak, oAuth2AccessToken, oAuth2RefreshToken);
OAuth2AccessTokenResponse tokenResponse = client.getTokenResponse(request);
