核心配置

Spring Boot 示例

Spring Boot 为 OAuth 2.0 登录提供了完整的自动配置功能。

本节展示了如何使用Google作为身份验证提供程序配置OAuth 2.0 登录示例,并涵盖以下主题

初始设置

要使用 Google 的 OAuth 2.0 身份验证系统进行登录,您必须在 Google API 控制台中设置一个项目以获取 OAuth 2.0 凭据。

Google 的 OAuth 2.0 实现 用于身份验证,符合OpenID Connect 1.0 规范,并且已获得OpenID 认证

按照OpenID Connect 页面上的说明进行操作,从“设置 OAuth 2.0”部分开始。

完成“获取 OAuth 2.0 凭据”说明后,您应该会拥有一个新的 OAuth 客户端,其凭据由客户端 ID 和客户端密钥组成。

设置重定向 URI

重定向 URI 是应用程序中终端用户的用户代理在他们使用 Google 进行身份验证并在同意页面上向 OAuth 客户端(在先前步骤中创建)授予访问权限后重定向回的路径。

在“设置重定向 URI”小节中,确保授权的重定向 URI字段设置为localhost:8080/login/oauth2/code/google

默认重定向 URI 模板为{baseUrl}/login/oauth2/code/{registrationId}registrationIdClientRegistration 的唯一标识符。

如果 OAuth 客户端位于代理服务器后面,则应检查代理服务器配置以确保应用程序配置正确。此外,请参阅受支持的URI 模板变量,以获取redirect-uri

配置 application.yml

现在您有了新的使用 Google 的 OAuth 客户端,您需要配置应用程序以使用 OAuth 客户端进行身份验证流程。为此

  1. 转到application.yml并设置以下配置

    spring:
      security:
        oauth2:
          client:
            registration:	(1)
              google:	(2)
                client-id: google-client-id
                client-secret: google-client-secret
    OAuth 客户端属性
    1 spring.security.oauth2.client.registration 是 OAuth 客户端属性的基本属性前缀。
    2 在基本属性前缀之后是ClientRegistration 的 ID,例如 Google。
  2. client-idclient-secret属性中的值替换为您之前创建的 OAuth 2.0 凭据。

启动应用程序

启动 Spring Boot 示例并访问 localhost:8080。然后您将重定向到默认的自动生成的登录页面,该页面显示了一个 Google 链接。

点击 Google 链接,然后您将重定向到 Google 进行身份验证。

使用您的 Google 帐户凭据进行身份验证后,您将看到同意屏幕。同意屏幕会要求您允许或拒绝访问您之前创建的 OAuth 客户端。点击允许授权 OAuth 客户端访问您的电子邮件地址和基本个人资料信息。

此时,OAuth 客户端从用户信息端点检索您的电子邮件地址和基本个人资料信息,并建立已认证的会话。

Spring Boot 属性映射

下表概述了 Spring Boot OAuth 客户端属性与ClientRegistration 属性的映射关系。

Spring Boot ClientRegistration

spring.security.oauth2.client.registration.[registrationId]

registrationId

spring.security.oauth2.client.registration.[registrationId].client-id

clientId

spring.security.oauth2.client.registration.[registrationId].client-secret

clientSecret

spring.security.oauth2.client.registration.[registrationId].client-authentication-method

clientAuthenticationMethod

spring.security.oauth2.client.registration.[registrationId].authorization-grant-type

authorizationGrantType

spring.security.oauth2.client.registration.[registrationId].redirect-uri

redirectUri

spring.security.oauth2.client.registration.[registrationId].scope

scopes

spring.security.oauth2.client.registration.[registrationId].client-name

clientName

spring.security.oauth2.client.provider.[providerId].authorization-uri

providerDetails.authorizationUri

spring.security.oauth2.client.provider.[providerId].token-uri

providerDetails.tokenUri

spring.security.oauth2.client.provider.[providerId].jwk-set-uri

providerDetails.jwkSetUri

spring.security.oauth2.client.provider.[providerId].issuer-uri

providerDetails.issuerUri

spring.security.oauth2.client.provider.[providerId].user-info-uri

providerDetails.userInfoEndpoint.uri

spring.security.oauth2.client.provider.[providerId].user-info-authentication-method

providerDetails.userInfoEndpoint.authenticationMethod

spring.security.oauth2.client.provider.[providerId].user-name-attribute

providerDetails.userInfoEndpoint.userNameAttributeName

您可以通过发现 OpenID Connect 提供商的配置端点或授权服务器的元数据端点,并指定spring.security.oauth2.client.provider.[providerId].issuer-uri属性来初始配置ClientRegistration

CommonOAuth2Provider

CommonOAuth2Provider 为许多知名提供商预定义了一组默认客户端属性:Google、GitHub、Facebook 和 Okta。

例如,authorization-uritoken-uriuser-info-uri 对于提供商来说并不经常更改。因此,提供默认值是有意义的,以减少所需的配置。

如前所述,当我们配置 Google 客户端时,只需要client-idclient-secret属性。

以下列表显示了一个示例

spring:
  security:
    oauth2:
      client:
        registration:
          google:
            client-id: google-client-id
            client-secret: google-client-secret
客户端属性的自动默认值在此处无缝工作,因为registrationIdgoogle)与CommonOAuth2Provider中的GOOGLE 枚举(不区分大小写)匹配。

在您可能希望指定不同registrationId(例如google-login)的情况下,您仍然可以通过配置provider属性来利用客户端属性的自动默认值。

以下列表显示了一个示例

spring:
  security:
    oauth2:
      client:
        registration:
          google-login:	(1)
            provider: google	(2)
            client-id: google-client-id
            client-secret: google-client-secret
1 registrationId设置为google-login
2 provider属性设置为google,它将利用CommonOAuth2Provider.GOOGLE.getBuilder()中设置的客户端属性的自动默认值。

配置自定义提供商属性

一些 OAuth 2.0 提供商支持多租户,这会导致每个租户(或子域)的协议端点不同。

例如,在 Okta 中注册的 OAuth 客户端被分配到特定的子域,并拥有自己的协议端点。

对于这些情况,Spring Boot 提供了以下基本属性来配置自定义提供商属性:spring.security.oauth2.client.provider.[providerId]

以下列表显示了一个示例

spring:
  security:
    oauth2:
      client:
        registration:
          okta:
            client-id: okta-client-id
            client-secret: okta-client-secret
        provider:
          okta:	(1)
            authorization-uri: https://your-subdomain.oktapreview.com/oauth2/v1/authorize
            token-uri: https://your-subdomain.oktapreview.com/oauth2/v1/token
            user-info-uri: https://your-subdomain.oktapreview.com/oauth2/v1/userinfo
            user-name-attribute: sub
            jwk-set-uri: https://your-subdomain.oktapreview.com/oauth2/v1/keys
1 基本属性(spring.security.oauth2.client.provider.okta)允许自定义配置协议端点位置。

覆盖 Spring Boot 自动配置

OAuth 客户端支持的 Spring Boot 自动配置类是OAuth2ClientAutoConfiguration

它执行以下任务

  • 注册一个ClientRegistrationRepository @Bean,该@Bean由配置的 OAuth 客户端属性中的ClientRegistration组成。

  • 注册一个SecurityFilterChain @Bean并通过httpSecurity.oauth2Login()启用 OAuth 2.0 登录。

如果您需要根据您的具体需求覆盖自动配置,您可以通过以下方式进行

注册一个 ClientRegistrationRepository @Bean

以下示例显示了如何注册一个ClientRegistrationRepository @Bean

  • Java

  • Kotlin

@Configuration
public class OAuth2LoginConfig {

	@Bean
	public ClientRegistrationRepository clientRegistrationRepository() {
		return new InMemoryClientRegistrationRepository(this.googleClientRegistration());
	}

	private ClientRegistration googleClientRegistration() {
		return ClientRegistration.withRegistrationId("google")
			.clientId("google-client-id")
			.clientSecret("google-client-secret")
			.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
			.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
			.redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
			.scope("openid", "profile", "email", "address", "phone")
			.authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")
			.tokenUri("https://www.googleapis.com/oauth2/v4/token")
			.userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
			.userNameAttributeName(IdTokenClaimNames.SUB)
			.jwkSetUri("https://www.googleapis.com/oauth2/v3/certs")
			.clientName("Google")
			.build();
	}
}
@Configuration
class OAuth2LoginConfig {
    @Bean
    fun clientRegistrationRepository(): ClientRegistrationRepository {
        return InMemoryClientRegistrationRepository(googleClientRegistration())
    }

    private fun googleClientRegistration(): ClientRegistration {
        return ClientRegistration.withRegistrationId("google")
                .clientId("google-client-id")
                .clientSecret("google-client-secret")
                .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
                .scope("openid", "profile", "email", "address", "phone")
                .authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")
                .tokenUri("https://www.googleapis.com/oauth2/v4/token")
                .userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
                .userNameAttributeName(IdTokenClaimNames.SUB)
                .jwkSetUri("https://www.googleapis.com/oauth2/v3/certs")
                .clientName("Google")
                .build()
    }
}

注册一个 SecurityFilterChain @Bean

以下示例显示了如何使用@EnableWebSecurity注册一个SecurityFilterChain @Bean并通过httpSecurity.oauth2Login()启用 OAuth 2.0 登录

OAuth2 登录配置
  • Java

  • Kotlin

@Configuration
@EnableWebSecurity
public class OAuth2LoginSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests(authorize -> authorize
				.anyRequest().authenticated()
			)
			.oauth2Login(withDefaults());
		return http.build();
	}
}
@Configuration
@EnableWebSecurity
class OAuth2LoginSecurityConfig {

    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            authorizeRequests {
                authorize(anyRequest, authenticated)
            }
            oauth2Login { }
        }
        return http.build()
    }
}

完全覆盖自动配置

以下示例显示了如何通过注册一个ClientRegistrationRepository @Bean和一个SecurityFilterChain @Bean来完全覆盖自动配置。

覆盖自动配置
  • Java

  • Kotlin

@Configuration
public class OAuth2LoginConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests(authorize -> authorize
				.anyRequest().authenticated()
			)
			.oauth2Login(withDefaults());
		return http.build();
	}

	@Bean
	public ClientRegistrationRepository clientRegistrationRepository() {
		return new InMemoryClientRegistrationRepository(this.googleClientRegistration());
	}

	private ClientRegistration googleClientRegistration() {
		return ClientRegistration.withRegistrationId("google")
			.clientId("google-client-id")
			.clientSecret("google-client-secret")
			.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)

			.jwkSetUri("https://www.googleapis.com/oauth2/v3/certs")
			.clientName("Google")
			.build();
	}
}
@Configuration
class OAuth2LoginConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            authorizeRequests {
                authorize(anyRequest, authenticated)
            }
            oauth2Login { }
        }
        return http.build()
    }

    @Bean
    fun clientRegistrationRepository(): ClientRegistrationRepository {
        return InMemoryClientRegistrationRepository(googleClientRegistration())
    }

    private fun googleClientRegistration(): ClientRegistration {
        return ClientRegistration.withRegistrationId("google")
                .clientId("google-client-id")
                .clientSecret("google-client-secret")
                .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
                .scope("openid", "profile", "email", "address", "phone")
                .authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")
                .tokenUri("https://www.googleapis.com/oauth2/v4/token")
                .userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
                .userNameAttributeName(IdTokenClaimNames.SUB)
                .jwkSetUri("https://www.googleapis.com/oauth2/v3/certs")
                .clientName("Google")
                .build()
    }
}

无 Spring Boot 的 Java 配置

如果您无法使用 Spring Boot 并希望配置CommonOAuth2Provider中预定义的提供商之一(例如 Google),请应用以下配置
