java - 为什么无法解析符号 TransactionWriteRequest 或 TransactionLoadRequest？

Question

我正在研究 dynamodb，并运行示例代码。我已经导入了所有依赖项，但它说

Cannot resolve symbol 'TransactionWriteRequest', 'TransactionLoadRequest','TransactionCanceledException' or 'DynamoDBTransactionWriteExpression'.

pom.xml:

xml
    <dependencies>
        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk</artifactId>
            <version>1.11.327</version>
        </dependency>
    </dependencies>

java:

import com.amazonaws.services.dynamodbv2.datamodeling.TransactionWriteRequest;
import com.amazonaws.services.dynamodbv2.datamodeling.TransactionLoadRequest;
import com.amazonaws.services.dynamodbv2.model.TransactionCanceledException;
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBTransactionWriteExpression;
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBTransactionLoadExpression;
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMappingException;
import com.amazonaws.services.dynamodbv2.model.ResourceNotFoundException;
import com.amazonaws.services.dynamodbv2.model.InternalServerErrorException;

尝试将 aws-java-sdk-dynamodb 依赖项版本升级到 1.11.590。
