Spring Boot 整合 OAuth2 安全框架是一个常见的需求，特别是在构建现代 Web 应用时。以下是一个基本的步骤指南，帮助你整合 Spring Boot 和 OAuth2。

1. 添加依赖

首先，在你的 pom.xml 文件中添加必要的依赖项。你需要 Spring Security 和 Spring Boot 的 OAuth2 支持。

<dependencies>
    <!-- Spring Security -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <!-- Spring Security OAuth2 -->
    <dependency>
        <groupId>org.springframework.security.oauth.boot</groupId>
        <artifactId>spring-security-oauth2-autoconfigure</artifactId>
    </dependency>
    <!-- Spring Boot Starter Web for creating RESTful services -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

2. 配置 OAuth2

在你的 application.yml 或 application.properties 文件中配置 OAuth2 客户端信息。

application.yml 示例

spring:
  security:
    oauth2:
      client:
        registration:
          my-client:
            client-id: your-client-id
            client-secret: your-client-secret
            authorization-grant-type: password
            scope: read,write
        provider:
          my-provider:
            issuer-uri: https://your-auth-server/oauth/token

application.properties 示例

spring.security.oauth2.client.registration.my-client.client-id=your-client-id
spring.security.oauth2.client.registration.my-client.client-secret=your-client-secret
spring.security.oauth2.client.registration.my-client.authorization-grant-type=password
spring.security.oauth2.client.registration.my-client.scope=read,write
spring.security.oauth2.provider.my-provider.issuer-uri=https://your-auth-server/oauth/token

3. 配置 Spring Security

创建一个配置类来设置 Spring Security 和 OAuth2。

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.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.client.registration.ClientRegistrationRepository;
import org.springframework.security.oauth2.client.web.OAuth2AuthorizedClientRepository;
import org.springframework.security.oauth2.server.resource.authentication.JwtBearerAuthenticationConverter;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
public class SecurityConfig {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
            .authorizeRequests(authorize -> authorize
                .antMatchers("/actuator/**").permitAll()
                .anyRequest().authenticated()
            )
            .oauth2Login(oauth2 -> oauth2
                .loginPage("/login")
                .defaultSuccessUrl("/home")
            );
        return http.build();
    }
}

4. 创建登录页面

创建一个简单的登录页面 src/main/resources/templates/login.html。

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Login</title>
</head>
<body>
    <h1>Login</h1>
    <form method="post" action="/login">
        <label for="username">Username:</label>
        <input type="text" id="username" name="username" required><br><br>
        <label for="password">Password:</label>
        <input type="password" id="password" name="password" required><br><br>
        <button type="submit">Login</button>
    </form>
</body>
</html>

5. 创建受保护的资源

创建一个简单的 RESTful 服务来测试保护资源。

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @GetMapping("/home")
    public String home() {
        return "Welcome to the home page!";
    }

    @GetMapping("/protected")
    public String protectedResource(OAuth2AuthorizedClient authorizedClient) {
        return "This is a protected resource. User: " + authorizedClient.getName();
    }
}

6. 启动应用

启动你的 Spring Boot 应用，并尝试访问受保护的资源。你应该会被重定向到 OAuth2 登录页面，登录成功后可以访问受保护的资源。

总结

以上步骤涵盖了 Spring Boot 整合 OAuth2 的基本流程。你可以根据需要进一步扩展和定制配置，例如添加更多的授权类型、配置客户端凭证授权等。
