我想使用客户端凭据授权生成访问令牌https://docs.spring.io/spring-security/site/docs/5.4.6/reference/html5/#oauth2client-客户信誉补助金
我们使用的是SpringSecurity 5.4.6
我已导入这些依赖项：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-oauth2-client</artifactId>
        </dependency>

这是一个资源服务器，它还必须根据cron计划发出服务器到服务器的身份验证请求。这就是为什么我需要 resource-server 及 oauth2-client 依赖关系。

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          jwk-set-uri: https://auth.pingone.com/...
      client:
        provider:
          pingidentity:
            token-uri: https://auth.pingone.com/.../as/token
        registration:
          pingidentity:
            client-id: "69bxxxxx..."
            client-secret: "Xxxxx"
            scope: openid
            authorization-grant-type: "client_credentials"

@Bean
    public OAuth2AuthorizedClientManager authorizedClientManager(
            ClientRegistrationRepository clientRegistrationRepository,
            OAuth2AuthorizedClientRepository authorizedClientRepository ) {

        OAuth2AuthorizedClientProvider authorizedClientProvider =
                OAuth2AuthorizedClientProviderBuilder.builder()
                        .clientCredentials()
                        .build();

        DefaultOAuth2AuthorizedClientManager authorizedClientManager =
                new DefaultOAuth2AuthorizedClientManager(
                        clientRegistrationRepository, authorizedClientRepository );
        authorizedClientManager.setAuthorizedClientProvider( authorizedClientProvider );

        return authorizedClientManager;
    }

    protected void setSecurityContext() {
        OAuth2AuthorizeRequest authorizeRequest = OAuth2AuthorizeRequest.withClientRegistrationId( "pingidentity" )
                .principal( "69bbfc70-8fcf-4740-a11a-b86562d1c9f8" )
//              .attributes( attrs -> {
//                  attrs.put( HttpServletRequest.class.getName(), servletRequest );
//                  attrs.put( HttpServletResponse.class.getName(), servletResponse );
//              } )
                .build();
        OAuth2AuthorizedClient authorizedClient = this.authorizedClientManager.authorize( authorizeRequest );

        OAuth2AccessToken accessToken = authorizedClient.getAccessToken();
}

我得到了这个错误：java.lang.illegalargumentexception:servletrequest不能在org.springframework.util.assert.notnull（assert.java:201）处为null，在org.springframework.security.oauth2.client.web.defaultoauth2authorizedclientmanager.authorize（defaultoauth2authorizedclientmanager.java:144）处为nullcom.edlogics.heathrow.api.scheduling.jobs.abstractschedulerjob.setsecuritycontext（abstractschedulerjob.java:42）位于com.edlogics.heathrow.api.scheduling.jobs.CheckFormisingCacheEntriesJob.execute（CheckFormisingCacheEntriesJob.java:32），位于org.quartz.siml.simplethreadpool$workerthread.run（simplethreadpool.java:573）
如何在web请求之外使用客户端凭据授权？
