前言
文章较长，步骤比较繁琐，请各位读者耐心观看。 上篇文章大概了解了下框架的相关理论，本篇文章将带大家一步步构建一个简单的认证服务器 开始之前先放一下文档的链接：官网文档
项目环境要求(当前框架版本1.1.0)
- Spring Boot版本大于等于3.1.0-RC1
- JDK版本大于等于17
认证项目搭建
1. 在Idea中或Spring Initializr中创建spring boot项目
-
Spring Boot版本选择3.1.0，Java版本选择17以上，在Dependencies中勾选Spring Authorization Server和spring web依赖，其它看自己需要
引入持久层框架（本人用的是MybatisPlus，读者可自选）
<dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.5.3.1</version> </dependency>引入webjars和bootstrap，自定义登录页和确认页面时使用
<dependency> <groupId>org.webjars</groupId> <artifactId>webjars-locator-core</artifactId> </dependency> <dependency> <groupId>org.webjars</groupId> <artifactId>bootstrap</artifactId> <version>5.2.3</version> </dependency>项目pom.xml示例
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>3.1.0</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>authorization-example</artifactId> <version>0.0.1-SNAPSHOT</version> <name>authorization-example</name> <description>authorization-example</description> <properties> <java.version>17</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-oauth2-authorization-server</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.5.3.1</version> </dependency> <dependency> <groupId>org.webjars</groupId> <artifactId>webjars-locator-core</artifactId> </dependency> <dependency> <groupId>org.webjars</groupId> <artifactId>bootstrap</artifactId> <version>5.2.3</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <excludes> <exclude> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </exclude> </excludes> </configuration> </plugin> </plugins> </build> </project> -
初始化框架自带数据库表
schema位置如图
修改后适配MySQL的SQL如下
-- 用户授权确认表 CREATE TABLE oauth2_authorization_consent ( registered_client_id varchar(100) NOT NULL, principal_name varchar(200) NOT NULL, authorities varchar(1000) NOT NULL, PRIMARY KEY (registered_client_id, principal_name) ); -- 用户认证信息表 CREATE TABLE oauth2_authorization ( id varchar(100) NOT NULL, registered_client_id varchar(100) NOT NULL, principal_name varchar(200) NOT NULL, authorization_grant_type varchar(100) NOT NULL, authorized_scopes varchar(1000) DEFAULT NULL, attributes blob DEFAULT NULL, state varchar(500) DEFAULT NULL, authorization_code_value blob DEFAULT NULL, authorization_code_issued_at DATETIME DEFAULT NULL, authorization_code_expires_at DATETIME DEFAULT NULL, authorization_code_metadata blob DEFAULT NULL, access_token_value blob DEFAULT NULL, access_token_issued_at DATETIME DEFAULT NULL, access_token_expires_at DATETIME DEFAULT NULL, access_token_metadata blob DEFAULT NULL, access_token_type varchar(100) DEFAULT NULL, access_token_scopes varchar(1000) DEFAULT NULL, oidc_id_token_value blob DEFAULT NULL, oidc_id_token_issued_at DATETIME DEFAULT NULL, oidc_id_token_expires_at DATETIME DEFAULT NULL, oidc_id_token_metadata blob DEFAULT NULL, refresh_token_value blob DEFAULT NULL, refresh_token_issued_at DATETIME DEFAULT NULL, refresh_token_expires_at DATETIME DEFAULT NULL, refresh_token_metadata blob DEFAULT NULL, user_code_value blob DEFAULT NULL, user_code_issued_at DATETIME DEFAULT NULL, user_code_expires_at DATETIME DEFAULT NULL, user_code_metadata blob DEFAULT NULL, device_code_value blob DEFAULT NULL, device_code_issued_at DATETIME DEFAULT NULL, device_code_expires_at DATETIME DEFAULT NULL, device_code_metadata blob DEFAULT NULL, PRIMARY KEY (id) ); -- 客户端表 CREATE TABLE oauth2_registered_client ( id varchar(100) NOT NULL, client_id varchar(100) NOT NULL, client_id_issued_at DATETIME DEFAULT CURRENT_TIMESTAMP NOT NULL, client_secret varchar(200) DEFAULT NULL, client_secret_expires_at DATETIME DEFAULT NULL, client_name varchar(200) NOT NULL, client_authentication_methods varchar(1000) NOT NULL, authorization_grant_types varchar(1000) NOT NULL, redirect_uris varchar(1000) DEFAULT NULL, post_logout_redirect_uris varchar(1000) DEFAULT NULL, scopes varchar(1000) NOT NULL, client_settings varchar(2000) NOT NULL, token_settings varchar(2000) NOT NULL, PRIMARY KEY (id) );
2. 在config包下创建AuthorizationConfig类，并添加配置
配置端点的过滤器链
/**
* 配置端点的过滤器链
*
* @param http spring security核心配置类
* @return 过滤器链
* @throws Exception 抛出
*/
@Bean
public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http) throws Exception {
// 配置默认的设置，忽略认证端点的csrf校验
OAuth2AuthorizationServerConfiguration.applyDefaultSecurity(http);
http.getConfigurer(OAuth2AuthorizationServerConfigurer.class)
// 开启OpenID Connect 1.0协议相关端点
.oidc(Customizer.withDefaults())
// 设置自定义用户确认授权页
.authorizationEndpoint(authorizationEndpoint -> authorizationEndpoint.consentPage(CUSTOM_CONSENT_PAGE_URI));
http
// 当未登录时访问认证端点时重定向至login页面
.exceptionHandling((exceptions) -> exceptions
.defaultAuthenticationEntryPointFor(
new LoginUrlAuthenticationEntryPoint("/login"),
new MediaTypeRequestMatcher(MediaType.TEXT_HTML)
)
)
// 处理使用access token访问用户信息端点和客户端注册端点
.oauth2ResourceServer((resourceServer) -> resourceServer
.jwt(Customizer.withDefaults()));
return http.build();
}
配置身份验证过滤器链
/**
* 配置认证相关的过滤器链
*
* @param http spring security核心配置类
* @return 过滤器链
* @throws Exception 抛出
*/
@Bean
public SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {
http.authorizeHttpRequests((authorize) -> authorize
// 放行静态资源
.requestMatchers("/assets/**", "/webjars/**", "/login").permitAll()
.anyRequest().authenticated()
)
// 指定登录页面
.formLogin(formLogin ->
formLogin.loginPage("/login")
);
// 添加BearerTokenAuthenticationFilter，将认证服务当做一个资源服务，解析请求头中的token
http.oauth2ResourceServer((resourceServer) -> resourceServer
.jwt(Customizer.withDefaults()));
return http.build();
}
配置密码解析器
/**
* 配置密码解析器，使用BCrypt的方式对密码进行加密和验证
*
* @return BCryptPasswordEncoder
*/
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
配置客户端repository
/**
* 配置客户端Repository
*
* @param jdbcTemplate db 数据源信息
* @param passwordEncoder 密码解析器
* @return 基于数据库的repository
*/
@Bean
public RegisteredClientRepository registeredClientRepository(JdbcTemplate jdbcTemplate, PasswordEncoder passwordEncoder) {
RegisteredClient registeredClient = RegisteredClient.withId(UUID.randomUUID().toString())
// 客户端id
.clientId("messaging-client")
// 客户端秘钥，使用密码解析器加密
.clientSecret(passwordEncoder.encode("123456"))
// 客户端认证方式，基于请求头的认证
.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
// 配置资源服务器使用该客户端获取授权时支持的方式
.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
.authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN)
.authorizationGrantType(AuthorizationGrantType.CLIENT_CREDENTIALS)
// 授权码模式回调地址，oauth2.1已改为精准匹配，不能只设置域名，并且屏蔽了localhost
.redirectUri("http://127.0.0.1:8080/login/oauth2/code/messaging-client-oidc")
// 配置一个百度的域名回调，稍后使用该回调获取code
.redirectUri("https://www.baidu.com")
// 该客户端的授权范围，OPENID与PROFILE是IdToken的scope，获取授权时请求OPENID的scope时认证服务会返回IdToken
.scope(OidcScopes.OPENID)
.scope(OidcScopes.PROFILE)
// 自定scope
.scope("message.read")
.scope("message.write")
// 客户端设置，设置用户需要确认授权
.clientSettings(ClientSettings.builder().requireAuthorizationConsent(true).build())
.build();
// 基于db存储客户端，还有一个基于内存的实现 InMemoryRegisteredClientRepository
JdbcRegisteredClientRepository registeredClientRepository = new JdbcRegisteredClientRepository(jdbcTemplate);
// 初始化客户端
RegisteredClient repositoryByClientId = registeredClientRepository.findByClientId(registeredClient.getClientId());
if (repositoryByClientId == null) {
registeredClientRepository.save(registeredClient);
}
// 设备码授权客户端
RegisteredClient deviceClient = RegisteredClient.withId(UUID.randomUUID().toString())
.clientId("device-message-client")
// 公共客户端
.clientAuthenticationMethod(ClientAuthenticationMethod.NONE)
// 设备码授权
.authorizationGrantType(AuthorizationGrantType.DEVICE_CODE)
.authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN)
// 自定scope
.scope("message.read")
.scope("message.write")
.build();
RegisteredClient byClientId = registeredClientRepository.findByClientId(deviceClient.getClientId());
if (byClientId == null) {
registeredClientRepository.save(deviceClient);
}
return registeredClientRepository;
}
如果数据库已经存在客户端数据或不需要默认设置，则直接注入一个JdbcRegisteredClientRepository即可
/**
* 配置客户端Repository
*
* @param jdbcTemplate db 数据源信息
* @return 基于数据库的repository
*/
@Bean
public RegisteredClientRepository registeredClientRepository(JdbcTemplate jdbcTemplate) {
return new JdbcRegisteredClientRepository(jdbcTemplate);
}
配置授权管理服务
/**
* 配置基于db的oauth2的授权管理服务
*
* @param jdbcTemplate db数据源信息
* @param registeredClientRepository 上边注入的客户端repository
* @return JdbcOAuth2AuthorizationService
*/
@Bean
public OAuth2AuthorizationService authorizationService(JdbcTemplate jdbcTemplate, RegisteredClientRepository registeredClientRepository) {
// 基于db的oauth2认证服务，还有一个基于内存的服务InMemoryOAuth2AuthorizationService
return new JdbcOAuth2AuthorizationService(jdbcTemplate, registeredClientRepository);
}
配置授权确认管理服务
/**
* 配置基于db的授权确认管理服务
*
* @param jdbcTemplate db数据源信息
* @param registeredClientRepository 客户端repository
* @return JdbcOAuth2AuthorizationConsentService
*/
@Bean
public OAuth2AuthorizationConsentService authorizationConsentService(JdbcTemplate jdbcTemplate, RegisteredClientRepository registeredClientRepository) {
// 基于db的授权确认管理服务，还有一个基于内存的服务实现InMemoryOAuth2AuthorizationConsentService
return new JdbcOAuth2AuthorizationConsentService(jdbcTemplate, registeredClientRepository);
}
配置jwk
/**
* 配置jwk源，使用非对称加密，公开用于检索匹配指定选择器的JWK的方法
*
* @return JWKSource
*/
@Bean
public JWKSource<SecurityContext> jwkSource() {
KeyPair keyPair = generateRsaKey();
RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();
RSAKey rsaKey = new RSAKey.Builder(publicKey)
.privateKey(privateKey)
.keyID(UUID.randomUUID().toString())
.build();
JWKSet jwkSet = new JWKSet(rsaKey);
return new ImmutableJWKSet<>(jwkSet);
}
/**
* 生成rsa密钥对，提供给jwk
*
* @return 密钥对
*/
private static KeyPair generateRsaKey() {
KeyPair keyPair;
try {
KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
keyPairGenerator.initialize(2048);
keyPair = keyPairGenerator.generateKeyPair();
} catch (Exception ex) {
throw new IllegalStateException(ex);
}
return keyPair;
}
配置jwt解析器
/**
* 配置jwt解析器
*
* @param jwkSource jwk源
* @return JwtDecoder
*/
@Bean
public JwtDecoder jwtDecoder(JWKSource<SecurityContext> jwkSource) {
return OAuth2AuthorizationServerConfiguration.jwtDecoder(jwkSource);
}
配置认证服务器设置
/**
* 添加认证服务器配置，设置jwt签发者、默认端点请求地址等
*
* @return AuthorizationServerSettings
*/
@Bean
public AuthorizationServerSettings authorizationServerSettings() {
return AuthorizationServerSettings.builder().build();
}
配置一个基于内存的默认用户
/**
* 先暂时配置一个基于内存的用户，框架在用户认证时会默认调用
* {@link UserDetailsService#loadUserByUsername(String)} 方法根据
* 账号查询用户信息，一般是重写该方法实现自己的逻辑
*
* @param passwordEncoder 密码解析器
* @return UserDetailsService
*/
@Bean
public UserDetailsService users(PasswordEncoder passwordEncoder) {
UserDetails user = User.withUsername("admin")
.password(passwordEncoder.encode("123456"))
.roles("admin", "normal")
.authorities("app", "web")
.build();
return new InMemoryUserDetailsManager(user);
}

3. 添加AuthorizationController，将请求转发至自定义的登录页面和用户确认授权页面

this.description = scopeDescriptions.getOrDefault(scope, DEFAULT_DESCRIPTION);
}
}
}
4. 在application.yml中配置db数据源
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/authorization-example?serverTimezone=UTC&userUnicode=true&characterEncoding=utf-8
username: root
password: root
5. 编写登录页面和用户授权确认页面
以下代码摘抄自官方示例
登录页面 login.html
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org">

<link rel="stylesheet" href="/assets/css/signin.css" th:href="@{/assets/css/signin.css}" />
</head>
<body>
<div class="container">
<form class="form-signin w-100 m-auto" method="post" th:action="@{/login}">
<div th:if="${param.error}" class="alert alert-danger" role="alert">

</div>
<div th:if="${param.logout}" class="alert alert-success" role="alert">

</div>
<h1 class="h3 mb-3 fw-normal">Please sign in</h1>
<div class="form-floating">
<input type="text" id="username" name="username" class="form-control" required autofocus>
<label for="username">Username</label>
</div>
<div class="form-floating">
<input type="password" id="password" name="password" class="form-control" required>
<label for="password">Password</label>
</div>
<div>
<button class="w-100 btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
</div>
</form>
</div>
</body>
</html>
登录页面css, signin.css
html,
body {
height: 100%;
}
body {
display: flex;
align-items: start;
padding-top: 100px;
background-color: #f5f5f5;
}
.form-signin {
max-width: 330px;
padding: 15px;
}
.form-signin .form-floating:focus-within {
z-index: 2;
}
.form-signin input[type="username"] {
margin-bottom: -1px;
border-bottom-right-radius: 0;
border-bottom-left-radius: 0;
}
.form-signin input[type="password"] {
margin-bottom: 10px;
border-top-left-radius: 0;
border-top-right-radius: 0;
}
用户授权确认页面consent.html

至此，一个简单的认证服务就搭建成功了。
本来不想设置自定义页面的，但是不知道是本人的网络问题，还是默认的页面里的css相关cdn无法访问，页面加载巨慢还丑，只能从官方示例中拿一下登录页面和用户授权确认页面，css改为从项目的webjars中引入
最后放一下项目结构图
6. 简单测试
1. 拼接url，访问授权接口
2. 授权接口检测到未登录，重定向至登录页面
3. 输入AuthorizationConfig中配置的账号密码
账号：admin, 密码：123456
4. 登录成功后跳转至授权确认页面
登录成功跳转至第1步的授权接口，授权接口检测到用户未确认授权，跳转至授权确认页面
选择对应的scope并提交确认权限
5. 提交后重定向至第1步的授权接口
授权接口生成code并重定向至第1步请求授权接口时携带的redirectUri地址，重定向时携带上参数code和state，我这里省略掉了state参数，重定向之后只会携带code参数；state用来防止CSRF攻击，正式请求需生成并携带state参数。
6. 用户确认授权后携带code跳转至redirectUri
一般来说配置的回调地址都是客户端的接口，接口在接收到回调时根据code去换取accessToken，接下来我会用postman模拟客户端发起一个http请求去换取token 不知道为什么在手机浏览器上看回调至百度的图片在平台显示违规，这里放一张另一个回调地址的替代图片
7. 根据code换取AccessToken
请求/oauth2/token接口
1. 设置Basic Auth
之前客户端设置的认证方式是CLIENT_SECRET_BASIC，所以需将客户端信息添加至请求头
2. 添加表单数据，发起POST请求
下列表单数据可添加至form-data也可添加至url params 参数中的code就是第6步回调时携带的code
注意：添加url params时redirect_uri参数要经过encodeURIComponent函数对回调地址进行编码
8. 参数解释
1. client_id: 客户端的id
2. client_secret: 客户端秘钥
3. redirect_uri：申请授权成功后的回调地址
4. response_type：授权码模式固定参数code
5. code_verifier：一段随机字符串
6. code_challenge：根据指定的加密方式将code_verifier加密后得到的字符串
7. code_challenge_method：加密方式
8. scope：客户端申请的授权范围
9. state：跟随authCode原样返回，防止CSRF攻击
10. grant_type：指定获取token 的方式：
1. refresh_token：刷新token
2. authorization_code：根据授权码模式的授权码获取
3. client_credentials：客户端模式获取
总结
本篇文章从0到1搭建了一个简单认证服务，解释了认证服务的各项配置用意，如何设置自己的登录页和授权确认页，如何让认证服务解析请求时携带的token，文章过长难免有遗漏的地方，如果文章中有遗漏或错误的地方请各位读者在评论区指出。
