Amazon web services 使用AWS DynamoDB时无法映射实体

我从dynamoDB开始。我使用注释映射，如下所示：

@DynamoDBTable(tableName = "ProductCatalogz")
public static class Book {
    private int id;+
    private String title;+
    private String ISBN;+
    private Set<String> bookAuthors;+

    // private DimensionType dimensionType;

    @DynamoDBHashKey(attributeName = "Id")
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    @DynamoDBAttribute(attributeName = "Title")
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    @DynamoDBAttribute(attributeName = "ISBN")
    public String getISBN() {
        return ISBN;
    }

    public void setISBN(String ISBN) {
        this.ISBN = ISBN;
    }
}

请帮助我

消息

未找到请求的资源

表示未找到Dynamo DB表。您应该首先通过AWS控制台、API或CLI创建它。

确保已在客户端上设置端点

BasicAWSCredentials b = new BasicAWSCredentials("Access Key ID","Secret Access Key");           
AmazonDynamoDBClient client = new AmazonDynamoDBClient(b);
client.setEndpoint("dynamodb.ap-northeast-1.amazonaws.com");    

请参阅DynamoDB端点的完整列表
