1.项目依赖

<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>   <groupId>com.me.mengyu.auth.net</groupId>   <artifactId>mengyu-love</artifactId>   <version>0.0.1-SNAPSHOT</version>   <packaging>war</packaging>   <description>Auth</description>   <dependencies>   <!-- JWT认证利用 -->   <dependency>     <groupId>io.jsonwebtoken</groupId>     <artifactId>jjwt-api</artifactId>     <version>0.11.5</version>     </dependency>     <dependency>       <groupId>io.jsonwebtoken</groupId>       <artifactId>jjwt-impl</artifactId>       <version>0.11.5</version>       <scope>runtime</scope>     </dependency>     <dependency>       <groupId>io.jsonwebtoken</groupId>       <artifactId>jjwt-jackson</artifactId>       <version>0.11.5</version>   </dependency>     <!-- OIDC认证利用 -->   <dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-oauth2-client</artifactId>     <version>3.0.0</version>   </dependency>   <dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-web</artifactId>     <version>3.0.0</version>   </dependency>   <dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-thymeleaf</artifactId>     <version>3.0.0</version>   </dependency>   <dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-security</artifactId>     <version>3.0.0</version>   </dependency> </dependencies> <build>     <plugins>       <plugin>         <groupId>org.apache.maven.plugins</groupId>         <artifactId>maven-war-plugin</artifactId>         <version>3.3.2</version>         <configuration>             <failOnMissingWebXml>false</failOnMissingWebXml>         </configuration>       </plugin>     </plugins>   </build> </project>

2.配置应用程序属性

       在 src/main/resources/application.yml 中配置 OIDC 相关属性，具体取决于您使用的身份提供者（如 Google、Okta、Auth0 等）：

spring:   security:     oauth2:       client:         registration:           my-client:             client-id: your-client-id             client-secret: your-client-secret             scope: openid, profile, email             redirect-uri: "{baseUrl}/login/oauth2/code/{registrationId}"             authorization-grant-type: authorization_code         provider:           my-provider:             authorization-uri: https://your-authorization-server.com/auth             token-uri: https://your-authorization-server.com/token             user-info-uri: https://your-authorization-server.com/userinfo

3.创建安全配置类

创建一个安全配置类，继承 WebSecurityConfigurerAdapter，以配置安全性：

package com.me.mengyu.love.config; 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; import org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint; @Configuration @EnableWebSecurity public class SecurityConfig {     @Bean     public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {         http             .authorizeRequests()                 .requestMatchers("/", "/login", "/error").permitAll() // 允许所有用户访问的页面                 .anyRequest().authenticated() // 其余请求需要认证             .and()             .oauth2Login()                 .loginPage("/login") // 自定义登录页                 .defaultSuccessUrl("/home", true) // 登录成功后的默认跳转页                 .failureUrl("/login?error=true") // 登录失败后的跳转页             .and()             .exceptionHandling()                 .authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/login")); // 未认证用户访问的处理                 return http.build(); // 返回构建的 HttpSecurity     } }

注意1：在 Spring Security 5.0 及以后的版本中，WebSecurityConfigurerAdapter 类已被标记为不推荐使用（deprecated）。因此，Spring Boot 3.0 和 Spring Security 5.7 及更高版本也不再需要使用 WebSecurityConfigurerAdapter。相应的配置可以通过新的安全配置方法来实现，使用 SecurityFilterChain 和 @EnableWebSecurity 注解来定义安全规则。

4.创建控制器

package com.me.mengyu.love.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; @Controller public class HomeController {     @GetMapping("/")     public String index() {         return "index"; // 返回首页视图     }     @GetMapping("/home")     public String home() {         return "home"; // 返回用户主页视图     }     @GetMapping("/login")     public String login() {         return "login"; // 返回登录视图     } }

5.创建视图

       在 src/main/resources/templates/ 下创建相应的 HTML 视图文件（例如，index.html, home.html, login.html）。

<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0">     <title>Index Page</title> </head> <body>     <h1>Welcome to the OIDC Demo!</h1>     <a href="/login">Login</a> </body> </html>

<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0">     <title>Login Page</title> </head> <body>     <h1>Login</h1>     <a href="/oauth2/authorization/my-client">Login with OIDC</a>     <div th:if="${param.error}">         <p>Login failed. Please try again.</p>     </div> </body> </html>

<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0">     <title>Home Page</title> </head> <body>     <h1>Welcome Home!</h1>     <p>You are successfully logged in.</p>     <a href="/">Logout</a> </body> </html>

6.运行应用程序

         可以通过访问 http://localhost:8080 来访问应用程序，进行 OIDC 登录测试。

7.处理用户信息

         要获取用户信息，您可以在控制器中注入 OAuth2AuthenticationToken，并提取用户详细信息：

package com.me.mengyu.love.controller; import org.springframework.security.core.annotation.AuthenticationPrincipal; import org.springframework.security.oauth2.client.authentication.OAuth2AuthenticationToken; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class UserController {     @GetMapping("/user")     public String user(@AuthenticationPrincipal OAuth2AuthenticationToken authentication) {         return "User: " + authentication.getPrincipal().getAttributes().toString();     } }
