Spring Cloud Oauth2 初探
关键字
OAuth2
spring cloud
spring security
你需要知道的
一个原则: 使用前一定先看官方文档,看不懂再来搜寻第三方资料。
- 你需要熟悉OAuth2.0的相关规范,以及各种授权方式的应用场景与流程。
- Spring Security 官方文档
- Spring OAuth2 官方文档
为何开始
一个Spring框架的应用,需要一种能够保护 API 接口的实现,尝试过 OAuth1.0
,发现更多的是有关OAuth2.0
的讨论,且Spring Security 也有队OAuth2
的支持,于是转而使用OAuth2
。
环境
Frame | version |
---|---|
Centos | 7 |
Spring Boot | 2.0.0.RELEASE |
Spring Cloud | Finchley.M8 |
Oracle JDK | 1.8 |
IDE | Idea |
依赖
其中核心依赖仅有
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
其中 Spring Security 已经包含在 Starter 中,无需再次声明,以保持 pom 简洁。
OAuth2 Authorization Server
要使用OAuth2 服务器,仅需要使用 @EnableAuthorizationServer
注解。
此外OAuth2 Server还依赖于Spring Security,还需要加上@EnableWebSecurity
注解。
当然,这还不够,根据Spring Security官方文档,你还需要继承WebSecurityConfigurerAdapter
类以使Security配置生效。
你可以继承但不做任何改动,以使用默认配置。
默认的WebSecurity安全配置与OAuth2Server安全配置不会产生冲突,无需过滤
/oauth/**
端点。
该注解(@EnableAuthorizationServer)可以加在任何
@Configuration
注解的地方,推荐放在相关的配置类上,而不推荐放在入口类**Application
上。
OAuthServerConfig.class
@Configuration
@EnableAuthorizationServer
@EnableWebSecurity
public class Oauth2ServerConfig {
/**
* Spring Security 安全配置
*/
@Configuration
public static class CustomWebSecurityConfiguration extends WebSecurityConfigurerAdapter {}
}
启动程序,可以看到 OAuth2 的相关接口已经实现了,Spring 的自动配置已经为我们做了许多工作了,以致于我们可以开箱即用。
值得注意的是,自动配置类为我们生成了一个用户名为:user
的 "user" 和一个 "client" :

security.oauth2.client.client-secret = f8934b27-c7d6-4821-bd7e-1f7270e7e7b8
尝试携带上面的信息进行GET请求:
http://127.0.0.1:8080/oauth/authorize?client_id=64b5dabe-a97c-4f60-8492-acd24fc7599d&response_type=code&scope=user&redirect_uri=http://www.baidu.com
会跳转到/login
页面进行登录验证,填入 user
和 log 中的密码 d457f3b2-a3d7-4ace-bfaf-44ab7bfd8ccc
即可验证通过。
重新跳转回授权页面,选择Approve
同意并进行授权后,页面跳转至redirect_url
并携带code
信息。
https://www.baidu.com/?code=bPVWmn
取得 code 之后,就可以向服务器继续请求access-token
了,使用 POST 方法继续请求。
需要注意的是你需要添加 Basic Auth 信息在请求头,
username
为 "client_id" ,password
为 "client_secret"
不出意外,你将会看到以下信息:
{
"access_token":"9d646451-c672-4aa6-a864-2e10ed0f29f1",
"token_type":"bearer",
"refresh_token":"d7c1c3ca-a30e-4889-b993-abf32822117d",
"expires_in":42138,
"scope":"user"
}
至此,我们已经完成了一整个authorization_code
类型的OAuth2授权了。

依赖
同样的,你只需要一个依赖:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
