我在用弹簧设置动力装置时遇到了困难。我确定我的pom文件中存在问题，我的打印跟踪是指我的数据源问题以及我目前没有使用的hibernate问题。我最终希望完成的是从我的数据库中打印出信息。谢谢你的帮助。
配置课程：
@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);
}
}

我刚刚移走
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
从pom.xml开始，错误已解决。
确保您使用的是com.amazonaws.services.dynamodbv2.datamodeling注释，而不是JPA的注释。
