通过DynamoDBMapper在条件写入中使用NOT_CONTAINS

DynamoDBMapper mapper = new DynamoDBMapper(dynamoDBClient);

// 创建一个条件对象
DynamoDBQueryExpression<MyItem> queryExpression = new DynamoDBQueryExpression<MyItem>()
    .withIndexName("IndexName")
    .withConsistentRead(false)
    .withKeyConditionExpression("partitionKey = :partitionValue")
    .withFilterExpression("NOT contains(attributeName, :substringValue)")
    .withExpressionAttributeValues(Map.of(":partitionValue", "partitionValue", ":substringValue", "substringValue"));

// 执行查询
List<MyItem> results = mapper.query(MyItem.class, queryExpression);
