springboot整合oauth2.0

Spring Boot可以与OAuth 2.0协议进行整合，实现授权和认证功能。下面是一些步骤：

1. 配置pom.xml文件，添加Spring Security OAuth2依赖。

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.3.7.RELEASE</version>
</dependency>

2. 配置application.properties文件，添加OAuth2配置。

# OAuth2 configuration
security.oauth2.client.client-id=client-id
security.oauth2.client.client-secret=client-secret
security.oauth2.client.access-token-uri=https://example.com/oauth/token
security.oauth2.client.user-authorization-uri=https://example.com/oauth/authorize
security.oauth2.client.scope=read,write
security.oauth2.client.grant-type=authorization_code
security.oauth2.resource.token-info-uri=https://example.com/oauth/check_token
security.oauth2.resource.user-info-uri=https://example.com/userinfo

3. 创建一个OAuth2客户端，用于向授权服务器发送请求并获取访问令牌。

@Configuration
@EnableOAuth2Sso
public class OAuth2ClientConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/", "/login**", "/error**")
            .permitAll()
            .anyRequest()
            .authenticated()
            .and()
            .logout()
            .logoutSuccessUrl("/")
            .permitAll()
            .and()
            .csrf()
            .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
    }

    @Bean
    public OAuth2RestTemplate oauth2RestTemplate(OAuth2ProtectedResourceDetails resource,
                                                 OAuth2ClientContext context) {
        return new OAuth2RestTemplate(resource, context);
    }

    @Bean
    @ConfigurationProperties("security.oauth2.client")
    public OAuth2ProtectedResourceDetails oauth2RemoteResource() {
        return new AuthorizationCodeResourceDetails();
    }

    @Bean
    public FilterRegistrationBean oauth2ClientFilterRegistration(
            OAuth2ClientContextFilter filter) {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(filter);
        registration.setOrder(-100);
        return registration;
    }
}

4. 创建一个OAuth2资源服务器，用于保护受保护的资源。

@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/api/**")
            .authenticated();
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.resourceId("my-resource-id");
    }
}

5. 创建一个授权服务器，用于颁发访问令牌。

@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private BCryptPasswordEncoder passwordEncoder;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            .withClient("client-id")
            .secret(passwordEncoder.encode("client-secret"))
            .authorizedGrantTypes("authorization_code", "refresh_token")
            .scopes("read", "write")
            .accessTokenValiditySeconds(3600)
            .refreshTokenValiditySeconds(7200)
            .redirectUris("http://localhost:8080/login/oauth2/code/my-client");
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager)
            .userDetailsService(userDetailsService);
    }

}

以上是整合OAuth2.0的一些步骤和代码示例。需要注意的是，OAuth2.0是一个复杂的协议，需要深入理解和熟练掌握。同时，需要根据实际业务需求进行相应的配置和开发。
