Java Spring Boot Oauth2客户端（反应式）相互TLS/SSL令牌uri

Spring boot2.3.x和Spring 5.x最近添加了对基于类配置反应式oauth2客户端的支持

我需要客户端凭据授予流配置

在没有相互TLS/SSL的情况下执行此调用是简单的

正常（无TLS/SSL）配置（

@configuration

）代码提取如下：-

@Bean
public ReactiveOAuth2AuthorizedClientManager authorizedClientManager(
        ReactiveClientRegistrationRepository clientRegistrationRepository,
        ServerOAuth2AuthorizedClientRepository authorizedClientRepository){

    ReactiveOAuth2AuthorizedClientProvider authorizedClientProvider = ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
            .clientCredentials()
            .build();

    DefaultReactiveOAuth2AuthorizedClientManager authorizedClientManager = new DefaultReactiveOAuth2AuthorizedClientManager(clientRegistrationRepository, authorizedClientRepository);

    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
    return authorizedClientManager;
}

@Bean("testClient")
public WebClient webClient(ReactiveOAuth2AuthorizedClientManager authorizedClientManager,
                           @Value("${test.client.base.url}") String baseUrl) {
    ServerOAuth2AuthorizedClientExchangeFilterFunction oauthFunction = new ServerOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager);
    oauthFunction.setDefaultClientRegistrationId("local");
    return WebClient.builder()
            .baseUrl(baseUrl)
            .filter(oauthFunction)
            .build();
}

@Bean
public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
    http.oauth2Client();
    return http.build();
}

属性文件

spring.security.oauth2.client.registration.local.authorization-grant-type=client_credentials
spring.security.oauth2.client.registration.local.client-id=client_id
spring.security.oauth2.client.registration.local.client-secret=client_secret

spring.security.oauth2.client.provider.local.token-uri=http://hostname:port/oauth/token
test.client.base.url=http://protected-resource/v1/apis

但是通过相互TLS（客户端证书）调用oauth2授权服务器是一件大事

怎么做？我希望与社区分享这一点，并在下面回答相同的问题。对该要求的回答和主要更改将在bean

authorizedClientManager

答案的范围是仅客户端凭据授权流，尽管其他oauth2授权流的更改应该类似，这也会有所帮助

@Bean
public ReactiveOAuth2AuthorizedClientManager authorizedClientManager(
        ReactiveClientRegistrationRepository clientRegistrationRepository,
        ServerOAuth2AuthorizedClientRepository authorizedClientRepository){

    // construct client credential token response client yourself
    WebClientReactiveClientCredentialsTokenResponseClient accessTokenResponseClient = new WebClientReactiveClientCredentialsTokenResponseClient();

    // construct the sslContext as per your needs and inject in below
    // and create httpClient by injecting your sslContext here
    HttpClient httpClient = HttpClient.create()
            .tcpConfiguration(client -> client.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 10000))
            .secure(sslContextSpec -> sslContextSpec.sslContext(sslContext));

    ClientHttpConnector httpConnector = new ReactorClientHttpConnector(httpClient);

    accessTokenResponseClient.setWebClient(WebClient.builder().clientConnector(httpConnector).build());

    ReactiveOAuth2AuthorizedClientProvider authorizedClientProvider = ReactiveOAuth2AuthorizedClientProviderBuilder
            .builder()
            .clientCredentials(c -> {
                c.accessTokenResponseClient(accessTokenResponseClient);
            }).build();

    DefaultReactiveOAuth2AuthorizedClientManager authorizedClientManager = new DefaultReactiveOAuth2AuthorizedClientManager(clientRegistrationRepository, authorizedClientRepository);

    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
    return authorizedClientManager;
}

在这里，如果您看到行

.secure（sslContextSpec->sslContextSpec.sslContext（sslContext））

您需要构造sslContext并注入相同的内容，这完全取决于您的代码设置
