在 spring 啟動 2.6.1 中使用 spring-cloud-gcp-pub-sub-stream-binder 時未發現內部方法錯誤

Question

我正在嘗試將 spring-cloud-gcp-pub-sub-stream-binder 集成到我的 spring 啟動項目中，以使用來自 gcp pub 子主題的事件並在運行項目時出現以下錯誤。

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    com.google.cloud.spring.stream.binder.pubsub.provisioning.PubSubChannelProvisioner.provisionConsumerDestination(PubSubChannelProvisioner.java:81)

The following method did not exist:

    'boolean com.google.pubsub.v1.TopicName.isParsableFrom(java.lang.String)'

The calling method's class, com.google.cloud.spring.stream.binder.pubsub.provisioning.PubSubChannelProvisioner, was loaded from the following location:

    jar:file:/Users/pranay.garg/.m2/repository/com/google/cloud/spring-cloud-gcp-pubsub-stream-binder/3.3.0/spring-cloud-gcp-pubsub-stream-binder-3.3.0.jar!/com/google/cloud/spring/stream/binder/pubsub/provisioning/PubSubChannelProvisioner.class

The called method's class, com.google.pubsub.v1.TopicName, is available from the following locations:

    jar:file:/Users/pranay.garg/.m2/repository/com/google/api/grpc/proto-google-cloud-pubsub-v1/1.84.0/proto-google-cloud-pubsub-v1-1.84.0.jar!/com/google/pubsub/v1/TopicName.class

The called method's class hierarchy was loaded from the following locations:

    com.google.pubsub.v1.TopicName: file:/Users/pranay.garg/.m2/repository/com/google/api/grpc/proto-google-cloud-pubsub-v1/1.84.0/proto-google-cloud-pubsub-v1-1.84.0.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes com.google.cloud.spring.stream.binder.pubsub.provisioning.PubSubChannelProvisioner and com.google.pubsub.v1.TopicName

我正在使用 spring boot v2.6.1 和我的 dependencyManagement

            <artifactId>spring-cloud-stream-binder-kafka</artifactId>
        </dependency

我認為這是版本兼容性問題，其中 PubSubChannelProvisioner 試圖調用 TopicName 中不存在的方法，但我無法找出解決方案。 如果您需要任何其他可能遺漏的信息，請告訴我。 任何幫助表示贊賞，謝謝。

Answer 1

我相信 sc-function 中的 GCP 適配器使用的是 proto-google-cloud-pubsub v1.0.0，而在您的情況下，您使用的是 1.84。 所以也許我們需要更新。 隨時提出問題 - https://github.com/spring-cloud/spring-cloud-function/issues

Answer 2

我在 spring-cloud-gcp github repo 上提出了問題並解決了問題。 原來是由於libraries-bom依賴管理版本解決方案中的版本沖突
