我正在尝试在以下spring / dynamoDB应用程序中运行测试。我不确定错误是什么试图告诉我，我只是确定这是一个映射错误。
我正在尝试做的是加载已经在我的AWS Dynamo数据库中说明的项目并拉入一个字符串以在System.out中输出。感谢您提前提供任何帮助。
@Configuration
@EnableDynamoDBRepositories(basePackages = "com.ronone")
public class AWSConfig {
@Value("${amazon.aws.accesskey}")
private String amazonAWSAccessKey;
@Value("${amazon.aws.secretkey}")
private String amazonAWSSecreyKey;
@Bean
public AWSCredentials awsCredentials(){
return new BasicAWSCredentials(amazonAWSAccessKey, amazonAWSSecreyKey);
}
@Bean
public AmazonDynamoDB amazonDynamoDB(AWSCredentials awsCredentials){
AmazonDynamoDB amazonDynamoDB = AmazonDynamoDBClientBuilder.standard()
.withCredentials(new AWSStaticCredentialsProvider(awsCredentials))
.withEndpointConfiguration(
new AwsClientBuilder.EndpointConfiguration("http://localhost:8080", "us-east-2"))
.build();
return amazonDynamoDB;
}
}
控制器
@RestController
public class CountryController {
private DynamoDBMapper dynamoDBMapper;
@Autowired
private AmazonDynamoDB dynamoDB;
@RequestMapping("/")
public String test(){
Country testCountry;
dynamoDBMapper = new DynamoDBMapper(dynamoDB);
testCountry = dynamoDBMapper.load(Country.class, "Algeria");
return "Country was: " + testCountry.getCountryName().toString();
}
}
