## 说明 ##

`Spring Authorization Server` 遵循[Oauth2.1][]和[OpenID Connect 1.0][]，它建立在`Spring Security`之上。

## 最小化项目 ##

### 创建项目 ###

要求JDK11以上

使用Idea创建一个Maven的Spring Boot(笔者使用的是`spring boot 2.7`)项目

pom需要引入`Authorization Server的配置`

<dependency>
 <groupId>org.springframework.security</groupId>
 <artifactId>spring-security-oauth2-authorization-server</artifactId>
 <version>0.3.1</version>
 </dependency>
 复制代码

完整的pom.xml文件如下：

### 配置 ###

使用`@Bean`和`@Configuration`创建配置，这是官方推荐的最小配置。
