GCP ADC 模拟服务帐户无法识别

Question

我正在将 ADC 与服务帐户模拟一起使用。当尝试使用 spring-cloud-gcp-pubsub 项目执行此操作时，我收到以下异常：“从流读取凭据时出错，无法识别‘type’值‘impersonated_service_account’。需要‘authorized_user’或‘service_account’。”。

这很奇怪，因为https://github.com/googleapis/google-auth-library-java/blob/8cf273815f197a8b6b3d08043151005456824cbc/oauth2_http/java/com/google/auth/oauth2/GoogleCredentials.java#L164-L179似乎显示“type”：“impersonated_service_account”应该被识别。

运行此参考项目时发生故障：https://spring.io/guides/gs/messaging-gcp-pubsub/更新到 Java17 和 SpringBoot 3.x 并更新依赖项以考虑 spring-cloud-gcp项目现在属于 com.google.cloud 而不是此处引用的 org.springframework.cloud https://spring.io/projects/spring-cloud-gcp 解决了问题。
