我只使用了一个 Java 类文件。

import org.springframework.context.annotation.Bean;

import com.google.cloud.spring.pubsub.core.PubSubTemplate;

@SpringBootApplication

    private static final String TOPIC = "order";

    @Bean

        return new PubSubMessageHandler(pubsubTemplate, TOPIC);

    @Autowired

    @PostMapping("/publishMessage")
    public String publishMessage() 
        messagingGateway.sendToPubsub("Hello! This is a Publisher message");
        return "Message published successfully";

这些是我的依赖项（pom.xml）

请帮忙。谢谢。

【问题讨论】：

Spring Cloud 2020.0.4 基本一天了。 2020.0.3之前的版本你试过了吗？好的，我试试以前的版本。 @João Dias 我试过这个版本（2020.0.3）。仍然遇到同样的错误。可能是您缺少触发自动配置的内容吗？也许尝试关注spring.io/guides/gs/messaging-gcp-pubsub。 @João Dias 我从您提供的上述链接下载了项目，但仍然遇到相同的错误。 【参考方案1】：

我解决了这个问题。由于我在application.properties 文件中犯了一个较小的错误，因此出现了这个问题。我用spring.cloud.gcp.project.id代替了spring.cloud.gcp.project-id。
