spring-boot - 无法使用 Spring Cloud 连接 AWS SES

Question

我使用 Spring Boot 制作了一个非常简单的 maven 项目。我正在尝试使用 Spring Cloud 连接 AWS SES。在运行项目时，我收到以下错误:

未定义有效的实例 ID

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cloud.aws.core.env.ResourceIdResolver.BEAN_NAME': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stackResourceRegistryFactoryBean' defined in class path resource [org/springframework/cloud/aws/autoconfigure/context/ContextStackAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.aws.core.env.stack.config.StackResourceRegistryFactoryBean]: Factory method 'stackResourceRegistryFactoryBean' threw exception; nested exception is java.lang.IllegalArgumentException: No valid instance id defined

我正在显示正在使用的文件片段:

         return AmazonSimpleEmailServiceClientBuilder.standard()
            .withCredentials(credentialsProvider)

        simpleMailMessage.setText("test content");
        this.mailSender.send(simpleMailMessage);

    @Override

        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

应用程序属性

cloud.aws.credentials.accessKey=${MyAccessKey}
cloud.aws.credentials.secretKey=${MySecretKey}
cloud.aws.region.static=us-east-1

我没有尝试连接到任何 EC2 实例。无法找到将 Spring Cloud 用于 SES 的任何适当文档

Answer 1

您几乎已经掌握了，只是缺少一个配置标志来阻止该异常的蔓延。

添加 cloud.aws.stack.auto = false到您的 application.properties 文件，因此它不会为应用程序启用自动堆栈名称检测。

您可以在文档中阅读更多相关信息:http://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_cloudformation_configuration_in_spring_boot
