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 Authorization Server 1.4.0！spring-doc.cn

开始

如果您刚刚开始使用 Spring Authorization Server，以下部分将引导您创建第一个应用程序。spring-doc.cn

系统要求

Spring Authorization Server 需要 Java 17 或更高版本的运行时环境。spring-doc.cn

安装 Spring 授权服务器

Spring Authorization Server 可以在您已经使用 Spring Security 的任何位置使用。spring-doc.cn

开始使用 Spring Authorization Server 的最简单方法是创建基于 Spring Boot 的应用程序。您可以使用 start.spring.io 生成基本项目，或使用默认授权服务器示例作为指南。然后将 Spring Boot 的 Spring Authorization Server Starters添加为依赖项：spring-doc.cn

Mavenspring-doc.cn
Gradlespring-doc.cn

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

implementation "org.springframework.boot:spring-boot-starter-oauth2-authorization-server"

有关将 Spring Boot 与 Maven 或 Gradle 一起使用的更多信息，请参见安装 Spring Boot。

或者，你可以使用以下示例添加 Spring Authorization Server，而不使用 Spring Boot：spring-doc.cn

Mavenspring-doc.cn
Gradlespring-doc.cn

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-oauth2-authorization-server</artifactId>
    <version>1.4.1-SNAPSHOT</version>
</dependency>

implementation "org.springframework.security:spring-security-oauth2-authorization-server:1.4.1-SNAPSHOT"

开发您的第一个应用程序

首先，您需要将所需的最少组件定义为 .使用依赖项时，定义以下属性， Spring Boot 将为你提供必要的定义：@Beanspring-boot-starter-oauth2-authorization-server@Beanspring-doc.cn

application.yml

server:
  port: 9000

logging:
  level:
    org.springframework.security: trace

spring:
  security:
    user:
      name: user
      password: password
    oauth2:
      authorizationserver:
        client:
          oidc-client:
            registration:
              client-id: "oidc-client"
              client-secret: "{noop}secret"
              client-authentication-methods:
                - "client_secret_basic"
              authorization-grant-types:
                - "authorization_code"
                - "refresh_token"
              redirect-uris:
                - "http://127.0.0.1:8080/login/oauth2/code/oidc-client"
              post-logout-redirect-uris:
                - "http://127.0.0.1:8080/"
              scopes:
                - "openid"
                - "profile"
            require-authorization-consent: true

除了 Getting Started 体验之外，大多数用户还希望自定义默认配置。下一节将演示如何自己提供所有必要的 bean。

定义必需的组件

如果要自定义默认配置（无论您是否使用 Spring Boot），则可以在 Spring 中定义最少的必需组件。@Bean@Configurationspring-doc.cn

这些组件可以定义如下：spring-doc.cn

这是快速入门的最低配置。要了解每个组件的用途，请参阅以下说明：spring-doc.cn

1	协议端点的 Spring Security 过滤器链。
2	用于身份验证的 Spring Security 过滤器链。
3	一个 `UserDetailsService` 实例，用于检索用户进行身份验证。
4	用于管理客户端的 `RegisteredClientRepository` 实例。
5	用于对访问令牌进行签名的实例。`com.nimbusds.jose.jwk.source.JWKSource`
6	的 with keys generated on startup 的实例，用于创建上述内容。`java.security.KeyPairJWKSource`
7	用于解码已签名访问令牌的 `JwtDecoder` 实例。
8	用于配置 Spring Authorization Server 的 `AuthorizationServerSettings` 实例。
