此版本仍在开发中，尚未被视为稳定版本。对于最新的稳定版本，请使用 Spring Boot 3.4.0！spring-doc.cadn.net.cn

Spring Security

如果 Spring Security 在 Classpath 上，则默认情况下 Web 应用程序是安全的。 Spring Boot 依靠 Spring Security 的内容协商策略来确定是否使用httpBasic或formLogin. 要向 Web 应用程序添加方法级安全性，您还可以添加@EnableMethodSecurity替换为所需的设置。其他信息可以在 Spring Security Reference Guide 中找到。spring-doc.cadn.net.cn

默认的UserDetailsService具有单个用户。用户名为user，并且密码是随机的，并且在应用程序启动时以 WARN 级别打印，如以下示例所示：spring-doc.cadn.net.cn

Using generated security password: 78fa095d-3f4c-48b1-ad50-e24c31d5cf35

This generated password is for development use only. Your security configuration must be updated before running your application in production.

如果您微调日志记录配置，请确保org.springframework.boot.autoconfigure.securitycategory 设置为 logWARN-level 消息。否则，不会打印默认密码。

您可以通过提供spring.security.user.name和spring.security.user.password.spring-doc.cadn.net.cn

默认情况下，您在 Web 应用程序中获得的基本功能包括：spring-doc.cadn.net.cn

一个UserDetailsService（或ReactiveUserDetailsService如果是 WebFlux 应用程序），则具有内存存储和具有生成密码的单个用户（参见SecurityProperties.User对于用户的属性）。spring-doc.cadn.net.cn
基于表单的登录或 HTTP Basic 安全性（取决于Accept标头）对于整个应用程序（如果 Actuator 在 Classpath 上，则包括 Actuator 端点）。spring-doc.cadn.net.cn
一个DefaultAuthenticationEventPublisher用于发布身份验证事件。spring-doc.cadn.net.cn

您可以提供不同的AuthenticationEventPublisher通过为其添加 Bean 来获取。spring-doc.cadn.net.cn

MVC 安全性

默认安全配置在SecurityAutoConfiguration和UserDetailsServiceAutoConfiguration.SecurityAutoConfiguration进口SpringBootWebSecurityConfiguration用于 Web 安全，以及UserDetailsServiceAutoConfiguration配置身份验证，这在非 Web 应用程序中也相关。spring-doc.cadn.net.cn

要完全关闭默认的 Web 应用程序安全配置，包括 Actuator 安全性，或者组合多个 Spring Security 组件，例如 OAuth2 客户端和资源服务器，请添加一个 bean 类型的SecurityFilterChain（这样做不会禁用UserDetailsService配置）。要同时关闭UserDetailsServiceconfiguration 中，添加一个UserDetailsService,AuthenticationProvider或AuthenticationManager.spring-doc.cadn.net.cn

自动配置UserDetailsService还将退出 Classpath 上的以下任何 Spring Security 模块：spring-doc.cadn.net.cn

spring-security-oauth2-clientspring-doc.cadn.net.cn
spring-security-oauth2-resource-serverspring-doc.cadn.net.cn
spring-security-saml2-service-providerspring-doc.cadn.net.cn

要使用UserDetailsService除了这些依赖项中的一个或多个之外，还可以定义您自己的InMemoryUserDetailsManager豆。spring-doc.cadn.net.cn

可以通过添加自定义SecurityFilterChain豆。 Spring Boot 提供了方便的方法，可用于覆盖 actuator endpoints 和 static 资源的访问规则。EndpointRequest可用于创建RequestMatcher基于management.endpoints.web.base-path财产。PathRequest可用于创建RequestMatcher以获取常用位置中的资源。spring-doc.cadn.net.cn

WebFlux 安全性

与 Spring MVC 应用程序类似，您可以通过添加spring-boot-starter-securityDependency。默认安全配置在ReactiveSecurityAutoConfiguration和UserDetailsServiceAutoConfiguration.ReactiveSecurityAutoConfiguration进口WebFluxSecurityConfiguration用于 Web 安全，以及UserDetailsServiceAutoConfiguration配置身份验证，这在非 Web 应用程序中也相关。spring-doc.cadn.net.cn

要完全关闭默认的 Web 应用程序安全配置，包括 Actuator 安全性，请添加一个 bean 类型的WebFilterChainProxy（这样做不会禁用UserDetailsService配置）。要同时关闭UserDetailsServiceconfiguration 中，添加一个ReactiveUserDetailsService或ReactiveAuthenticationManager.spring-doc.cadn.net.cn

当以下任何 Spring Security 模块位于 Classpath 上时，自动配置也将退缩：spring-doc.cadn.net.cn

spring-security-oauth2-clientspring-doc.cadn.net.cn
spring-security-oauth2-resource-serverspring-doc.cadn.net.cn

要使用ReactiveUserDetailsService除了这些依赖项中的一个或多个之外，还可以定义您自己的MapReactiveUserDetailsService豆。spring-doc.cadn.net.cn

访问规则和多个 Spring Security 组件（如 OAuth 2 客户端和资源服务器）的使用可以通过添加自定义SecurityWebFilterChain豆。 Spring Boot 提供了方便的方法，可用于覆盖 actuator endpoints 和 static 资源的访问规则。EndpointRequest可用于创建ServerWebExchangeMatcher基于management.endpoints.web.base-path财产。spring-doc.cadn.net.cn

PathRequest可用于创建ServerWebExchangeMatcher以获取常用位置中的资源。spring-doc.cadn.net.cn

例如，您可以通过添加如下内容来自定义您的安全配置：spring-doc.cadn.net.cn

OAuth2

OAuth2 是 Spring 支持的广泛使用的授权框架。spring-doc.cadn.net.cn

客户端

如果你有spring-security-oauth2-client在您的 Classpath 上，您可以利用一些自动配置来设置 OAuth2/Open ID Connect 客户端。此配置使用OAuth2ClientProperties. 相同的属性适用于 servlet 和 reactive 应用程序。spring-doc.cadn.net.cn

您可以在spring.security.oauth2.clientprefix，如以下示例所示：spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.client.registration.my-login-client.client-id=abcd

spring:
  security:
    oauth2:
      client:
        registration:

            provider: "my-oauth-provider"
            scope: "openid,profile,email,phone,address"
            redirect-uri: "{baseUrl}/login/oauth2/code/{registrationId}"
            client-authentication-method: "client_secret_basic"

            client-authentication-method: "client_secret_basic"
            authorization-grant-type: "authorization_code"

          my-client-2:
            client-id: "abcd"
            client-secret: "password"
            client-name: "Client for email scope"
            provider: "my-oauth-provider"
            scope: "email"
            redirect-uri: "{baseUrl}/authorized/email"
            client-authentication-method: "client_secret_basic"

            token-uri: "https://my-auth-server.com/oauth2/token"
            user-info-uri: "https://my-auth-server.com/userinfo"
            user-info-authentication-method: "header"
            jwk-set-uri: "https://my-auth-server.com/oauth2/jwks"
            user-name-attribute: "name"

对于支持 OpenID Connect 发现的 OpenID Connect 提供商，可以进一步简化配置。提供程序需要配置一个issuer-uri，这是它断言为其颁发者标识符的 URI。例如，如果issuer-uri如果是 “https://example.com”，则将向 “https://example.com/.well-known/openid-configuration” 发出“OpenID 提供程序配置请求”。结果应为“OpenID Provider Configuration Response”。以下示例显示了如何使用issuer-uri:spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.client.provider.oidc-provider.issuer-uri=https://dev-123456.oktapreview.com/oauth2/default/

spring:
  security:
    oauth2:
      client:

          oidc-provider:
            issuer-uri: "https://dev-123456.oktapreview.com/oauth2/default/"

默认情况下，Spring Security 的OAuth2LoginAuthenticationFilter仅处理匹配的 URL/login/oauth2/code/*. 如果要自定义redirect-uri要使用其他模式，您需要提供配置来处理该自定义模式。例如，对于 servlet 应用程序，您可以添加自己的SecurityFilterChain类似于以下内容：spring-doc.cadn.net.cn

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;

@Configuration(proxyBeanMethods = false)
@EnableWebSecurity
public class MyOAuthClientConfiguration {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests((requests) -> requests
				.anyRequest().authenticated()
			)
			.oauth2Login((login) -> login
				.redirectionEndpoint((endpoint) -> endpoint
					.baseUri("/login/oauth2/callback/*")
				)
			);
		return http.build();
	}

}

import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.security.config.annotation.web.builders.HttpSecurity
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity
import org.springframework.security.config.annotation.web.invoke
import org.springframework.security.web.SecurityFilterChain

@Configuration(proxyBeanMethods = false)
@EnableWebSecurity
open class MyOAuthClientConfiguration {

	@Bean
	open fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			authorizeHttpRequests {
				authorize(anyRequest, authenticated)
			}
			oauth2Login {
				redirectionEndpoint {
					baseUri = "/login/oauth2/callback/*"
				}
			}
		}
		return http.build()
	}

}

Spring Boot 会自动配置InMemoryOAuth2AuthorizedClientServiceSpring Security 使用它来管理 Client 端注册。这InMemoryOAuth2AuthorizedClientService功能有限，我们建议仅将其用于开发环境。对于生产环境，请考虑使用JdbcOAuth2AuthorizedClientService或创建您自己的OAuth2AuthorizedClientService.

常见提供商的 OAuth2 客户端注册

对于常见的 OAuth2 和 OpenID 提供程序（包括 Google、Github、Facebook 和 Okta），我们提供了一组提供程序默认值（google,github,facebook和okta）。spring-doc.cadn.net.cn

如果您不需要自定义这些提供程序，则可以设置provider属性设置为需要推断 defaults 的 URL。此外，如果 Client 端注册的密钥与默认支持的提供程序匹配，则 Spring Boot 也会推断这一点。spring-doc.cadn.net.cn

换句话说，以下示例中的两个配置使用 Google 提供程序：spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.client.registration.my-client.client-id=abcd
spring.security.oauth2.client.registration.my-client.client-secret=password
spring.security.oauth2.client.registration.my-client.provider=google
spring.security.oauth2.client.registration.google.client-id=abcd
spring.security.oauth2.client.registration.google.client-secret=password

spring:
  security:
    oauth2:
      client:
        registration:
          my-client:
            client-id: "abcd"
            client-secret: "password"
            provider: "google"
          google:
            client-id: "abcd"
            client-secret: "password"

资源服务器

如果你有spring-security-oauth2-resource-server在你的 Classpath 上，Spring Boot 可以设置一个 OAuth2 资源服务器。对于 JWT 配置，需要指定 JWK Set URI 或 OIDC Issuer URI，如以下示例所示：spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.resourceserver.jwt.jwk-set-uri=https://example.com/oauth2/default/v1/keys

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          jwk-set-uri: "https://example.com/oauth2/default/v1/keys"

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.resourceserver.jwt.issuer-uri=https://dev-123456.oktapreview.com/oauth2/default/

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          issuer-uri: "https://dev-123456.oktapreview.com/oauth2/default/"

如果授权服务器不支持 JWK 集 URI，则可以使用用于验证 JWT 签名的公钥来配置资源服务器。这可以使用spring.security.oauth2.resourceserver.jwt.public-key-location属性，其中该值需要指向包含 PEM 编码的 x509 格式的公钥的文件。

这spring.security.oauth2.resourceserver.jwt.audiences属性可用于指定 JWT 中 aud 声明的预期值。例如，要求 JWT 包含值为my-audience:spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.resourceserver.jwt.audiences[0]=my-audience

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          audiences:
            - "my-audience"

相同的属性适用于 servlet 和响应式应用程序。或者，您可以定义自己的JwtDecoderbean 用于 servlet 应用程序或ReactiveJwtDecoder用于响应式应用。spring-doc.cadn.net.cn

如果使用不透明令牌而不是 JWT，您可以配置以下属性以通过自省验证令牌：spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.resourceserver.opaquetoken.introspection-uri=https://example.com/check-token
spring.security.oauth2.resourceserver.opaquetoken.client-id=my-client-id
spring.security.oauth2.resourceserver.opaquetoken.client-secret=my-client-secret

spring:
  security:
    oauth2:
      resourceserver:
        opaquetoken:
          introspection-uri: "https://example.com/check-token"
          client-id: "my-client-id"
          client-secret: "my-client-secret"

同样，相同的属性适用于 servlet 和 reactive 应用程序。或者，您可以定义自己的OpaqueTokenIntrospectorbean 用于 servlet 应用程序或ReactiveOpaqueTokenIntrospector用于响应式应用。spring-doc.cadn.net.cn

授权服务器

如果你有spring-security-oauth2-authorization-server在你的 Classpath 上，你可以利用一些自动配置来设置基于 Servlet 的 OAuth2 授权服务器。spring-doc.cadn.net.cn

您可以在spring.security.oauth2.authorizationserver.clientprefix，如以下示例所示：spring-doc.cadn.net.cn

Propertiesspring-doc.cadn.net.cn
YAMLspring-doc.cadn.net.cn

spring.security.oauth2.authorizationserver.client.my-client-1.registration.client-id=abcd

              client-secret: "{noop}secret1"
              client-authentication-methods:

                - "email"
                - "phone"
                - "address"
            require-authorization-consent: true
          my-client-2:
            registration:

              client-secret: "{noop}secret2"
              client-authentication-methods:
                - "client_secret_jwt"
              authorization-grant-types:

            jwk-set-uri: "https://my-client-2.com/jwks"
            token-endpoint-authentication-signing-algorithm: "RS256"

这client-secret属性的格式必须与配置的PasswordEncoder. 默认的PasswordEncoder通过以下方式创建PasswordEncoderFactories.createDelegatingPasswordEncoder().

Spring Boot 为 Spring Authorization Server 提供的自动配置旨在快速入门。大多数应用程序都需要定制，并且希望定义多个 bean 以覆盖自动配置。spring-doc.cadn.net.cn

可以将以下组件定义为 bean 以覆盖特定于 Spring Authorization Server 的自动配置：spring-doc.cadn.net.cn

RegisteredClientRepositoryspring-doc.cadn.net.cn
AuthorizationServerSettingsspring-doc.cadn.net.cn
SecurityFilterChainspring-doc.cadn.net.cn
com.nimbusds.jose.jwk.source.JWKSource<com.nimbusds.jose.proc.SecurityContext>spring-doc.cadn.net.cn
JwtDecoderspring-doc.cadn.net.cn

Spring Boot 会自动配置InMemoryRegisteredClientRepositorySpring Authorization Server 使用它来管理已注册的 Client 端。这InMemoryRegisteredClientRepository功能有限，我们建议仅将其用于开发环境。对于生产环境，请考虑使用JdbcRegisteredClientRepository或创建您自己的RegisteredClientRepository.

其他信息可以在 Spring Authorization Server Reference Guide 的 Getting Started 章节中找到。spring-doc.cadn.net.cn

SAML 2.0 版本

依赖方

如果你有spring-security-saml2-service-provider在您的 Classpath 上，您可以利用一些自动配置来设置 SAML 2.0 依赖方。此配置使用Saml2RelyingPartyProperties.spring-doc.cadn.net.cn

信赖方注册表示身份提供程序（IDP）和服务提供商（SP）之间的配对配置。您可以在spring.security.saml2.relyingpartyprefix，如以下示例所示：spring-doc.cadn.net.cn

对于 SAML2 注销，默认情况下， Spring Security 的Saml2LogoutRequestFilter和Saml2LogoutResponseFilter仅处理匹配的 URL/logout/saml2/slo. 如果要自定义urlAP 发起的注销请求将发送到哪个 AP 或response-urlAP 向其发送注销响应，要使用其他模式，您需要提供配置以处理该自定义模式。例如，对于 servlet 应用程序，您可以添加自己的SecurityFilterChain类似于以下内容：spring-doc.cadn.net.cn

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.SecurityFilterChain;

import static org.springframework.security.config.Customizer.withDefaults;

@Configuration(proxyBeanMethods = false)
public class MySamlRelyingPartyConfiguration {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http.authorizeHttpRequests((requests) -> requests.anyRequest().authenticated());
		http.saml2Login(withDefaults());
		http.saml2Logout((saml2) -> saml2.logoutRequest((request) -> request.logoutUrl("/SLOService.saml2"))
			.logoutResponse((response) -> response.logoutUrl("/SLOService.saml2")));
		return http.build();
	}
