Spring Boot 错误：“找不到能够从类型 [java.lang.String] 转换为类型 [....client.OAuth2ClientProperties$Registration] 的转换器”

Question

application.yaml

security:
    oauth2:
      resourceserver:
        jwt:
          issuer-uri: <okta issuer uri>
      client:
        registration:
          internal-client: okta
          client-id: <My- client id>
          client-secret: <My client secret>
          authorization-grant-type: client_credentails
          scope: internal
        provider:
          okta:
            issuer-uri: <okta issuer uri>
            
          
        
okta:
  oauth2:
    issuer: <okta issuer uri>
    audience: api://default

上面的代码是我的Spring Boot应用程序的application.yaml文件。

package DemoService.ConfigClasses;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.ClientHttpRequestInterceptor;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClientManager;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClientProvider;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClientProviderBuilder;
import org.springframework.security.oauth2.client.registration.ClientRegistrationRepository;
import org.springframework.security.oauth2.client.web.DefaultOAuth2AuthorizedClientManager;
import org.springframework.security.oauth2.client.web.OAuth2AuthorizedClientRepository;
import org.springframework.web.client.RestTemplate;

import DemoService.ConfigClasses.Interceptors.RestTemplateInterceptor;

@Configuration
public class DemoConf {

    @Autowired
    private ClientRegistrationRepository clientRegistrationRepository;
    @Autowired
    private OAuth2AuthorizedClientRepository oAuth2AuthorizedClientRepository;
    
    @Bean
    public RestTemplate restTemplate() {
        RestTemplate restTemplate= new RestTemplate();
        List<ClientHttpRequestInterceptor> interceptor=new ArrayList<>();
        interceptor.add(new RestTemplateInterceptor(manager(clientRegistrationRepository,oAuth2AuthorizedClientRepository)));
        return restTemplate;
    }
    @Bean
    public OAuth2AuthorizedClientManager manager(ClientRegistrationRepository clientRegistrationRepository,
            OAuth2AuthorizedClientRepository auth2AuthorizedClientRepository) {
        OAuth2AuthorizedClientProvider provider=OAuth2AuthorizedClientProviderBuilder.builder().clientCredentials().build();
        DefaultOAuth2AuthorizedClientManager defaultOAuth2AuthorizedClientManager=new DefaultOAuth2AuthorizedClientManager(clientRegistrationRepository, auth2AuthorizedClientRepository);
        defaultOAuth2AuthorizedClientManager.setAuthorizedClientProvider(provider);
        return defaultOAuth2AuthorizedClientManager;
    }

}

这是我的配置类

package DemoService.ConfigClasses;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.SecurityFilterChain;
import org.springframework.security.web.server.SecurityWebFilterChain;

@Configuration
@EnableWebFluxSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig {

    @Bean
    public SecurityWebFilterChain securityFilterChain(ServerHttpSecurity httpSecurity) {
        httpSecurity.authorizeExchange()
                    .anyExchange()
                    .authenticated()
                    .and()
                    .oauth2ResourceServer()
                    .jwt();
        
        return httpSecurity.build();
    }
}

网络安全配置类

package DemoService.ConfigClasses.Interceptors;

import java.io.IOException;

import org.springframework.http.HttpRequest;
import org.springframework.http.client.ClientHttpRequestExecution;
import org.springframework.http.client.ClientHttpRequestInterceptor;
import org.springframework.http.client.ClientHttpResponse;
import org.springframework.security.oauth2.client.OAuth2AuthorizeRequest;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClientManager;

public class RestTemplateInterceptor implements ClientHttpRequestInterceptor{

    private OAuth2AuthorizedClientManager manager;
    
    
    
    public RestTemplateInterceptor(OAuth2AuthorizedClientManager manager) {
        super();
        this.manager = manager;
    }



    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution)
            throws IOException {
        String token=manager.authorize(OAuth2AuthorizeRequest.withClientRegistrationId("internal-client").principal("internal").build()).getAccessToken().getTokenValue();
        
        request.getHeaders().add("Authorization", "Bearer "+token);
        return execution.execute(request, body);
    }
    
}

Rest 模板拦截器类

我正在尝试创建一个内部服务，并使用 okta oauth2 添加 spring security 来保护该服务。我正在为此服务实施基于令牌的授权。启动服务时显示以下错误：

Answer 1

您的属性至少有两个错误：

• registration

  属性下缺少一个级别（您稍后引用为

  internal-client

  的注册 ID）（这是当前异常的原因）
• 在您的

  registration

  中，您使用

  internal-client

  （而不是

  provider

  ）引用提供商

尝试：

okta-issuer: change-me
internal-client-id: change-me
internal-client-secret: change-me

security:
    oauth2:
      resourceserver:
        jwt:
          issuer-uri: ${okta-issuer}
      client:
        registration:
          internal-client:
            provider: okta
            client-id: ${internal-client-id}
            client-secret: ${internal-client-secret}
            authorization-grant-type: client_credentails
