无法在Spring Boot中配置DynamoDB

Question

我很难用Spring安装发电机。我确信我的pom文件中有一个问题，询问我的打印跟踪是指我的数据源的问题和我目前没有使用的Hibernate的问题。我最终希望完成的是从我的数据库中打印出信息。感谢任何帮助。

配置类：

@Configuration
@EnableDynamoDBRepositories
public class AWSConfig {

    @Value("${amazon.dynamodb.endpoint}")
    private String amazonDynamoDBEndpoint;

    @Value("${amazon.dynamodb.accesskey}")
    private String amazonAWSAccessKey;

    @Value("${amazon.dynamodb.secretkey}")
    private String amazonAWSSecreyKey;

    @Bean
    public AmazonDynamoDB amazonDynamoDB(){
        AmazonDynamoDB amazonDynamoDB = AmazonDynamoDBClientBuilder.standard().withEndpointConfiguration(
                new AwsClientBuilder.EndpointConfiguration("http://localhost:8080", "us-east-2"))
                .build();
        return amazonDynamoDB;
    }

    @Bean
    public AWSCredentials amazonAWSCredentials(){
        return new BasicAWSCredentials(amazonAWSAccessKey, amazonAWSSecreyKey);
    }

}

我刚搬走

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

从pom。xml，错误已解决。确保您正在使用com。亚马逊。服务。发电机BV2。数据建模注释，而不是JPA。
