Java 将PubSub emulator与Spring Cloud GCP一起使用时出错（未实现：未找到方法）

我正在尝试使用SpringCloudGCPpubsub与PubSub模拟器通信

依赖关系：

org.springframework.cloud
spring cloud gcp starter pubsub
1.2.0.2平方米

我还有一个

应用程序。属性

：

spring.cloud.gcp.pubsub.emulator-host=localhost:8081
spring.cloud.gcp.pubsub.project-id=test

在启动集成测试以检查主题是否存在后，出现以下错误：

com.google.api.gax.rpc.UnimplementedException: io.grpc.StatusRuntimeException: UNIMPLEMENTED: Method not found: google.pubsub.v1.Publisher/GetTopic

原因：

使用的代码：

package br.com.stilingue.pubsub；
导入br.com.stilingue.pubsub.pubsub应用程序；
导入org.junit.Assert；
导入org.junit.Test；
导入org.junit.runner.RunWith；
导入org.springframework.beans.factory.annotation.Autowired；
导入org.springframework.boot.test.context.SpringBootTest；
导入org.springframework.cloud.gcp.autoconfigure.pubsub.GcpPubSubProperties；
导入org.springframework.cloud.gcp.pubsub.PubSubAdmin；
导入org.springframework.cloud.gcp.pubsub.core.PubSubTemplate；
导入org.springframework.test.context.ContextConfiguration；
导入org.springframework.test.context.junit4.SpringRunner；
@RunWith（SpringRunner.class）
@SpringBootTest（类=PubSubApplication.class）
@ContextConfiguration（类={PubSubApplication.class}）
公共类PubSubApplicationTest{
@自动连线GcpPubSubProperties；
@自动连线PubSubTemplate PubSubTemplate；
@自动连线PubSubAdmin PubSubAdmin；
@试验
public void testTopicIsNull（）{
Assert.assertNull（this.pubSubAdmin.getTopic（“主题名”）；
}
}

我的搜索没有找到此代码不起作用的任何原因

有什么建议吗
