如何向WebClient添加OAuth 2.0承载令牌

import org.springframework.security.oauth2.client.DefaultOAuth2AuthorizedClientManager;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClient;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClientManager;
import org.springframework.security.oauth2.client.annotation.RegisteredOAuth2AuthorizedClient;
import org.springframework.security.oauth2.client.annotation.WithOAuth2Scope;
import org.springframework.security.oauth2.client.annotation.WithOAuth2Token;
import org.springframework.security.oauth2.client.registration.ClientRegistrationRepository;
import org.springframework.security.oauth2.core.OAuth2AccessToken;
import org.springframework.web.reactive.function.client.WebClient;

// 注入ClientRegistrationRepository和OAuth2AuthorizedClientManager
public class MyWebClient {
    private final WebClient webClient;
    private final OAuth2AuthorizedClientManager authorizedClientManager;

    public MyWebClient(ClientRegistrationRepository clientRegistrationRepository,
                       OAuth2AuthorizedClientManager authorizedClientManager) {
        this.webClient = WebClient.builder().build();
        this.authorizedClientManager = authorizedClientManager;
    }

    // 使用OAuth 2.0承载令牌进行请求
    @WithOAuth2Token // 使用默认的OAuth 2.0承载令牌
    public Mono<String> getResource() {
        return webClient.get()
                .uri("https://api.example.com/resource")
                .retrieve()
                .bodyToMono(String.class);
    }

    // 使用OAuth 2.0承载令牌和指定的作用域进行请求
    @WithOAuth2Scope("read") // 指定作用域为"read"
    public Mono<String> getScopedResource() {
        return webClient.get()
                .uri("https://api.example.com/scoped-resource")
                .retrieve()
                .bodyToMono(String.class);
    }

    // 使用指定的OAuth 2.0承载令牌进行请求
    public Mono<String> getResourceWithToken(@RegisteredOAuth2AuthorizedClient("example") OAuth2AuthorizedClient authorizedClient) {
        OAuth2AccessToken accessToken = authorizedClient.getAccessToken();
        String tokenValue = accessToken.getTokenValue();

        return webClient.get()
                .uri("https://api.example.com/resource")
                .header("Authorization", "Bearer " + tokenValue)
                .retrieve()
                .bodyToMono(String.class);
    }
}
