如何将DynamoDB表映射到Java中？

import com.amazonaws.services.dynamodbv2.datamodeling.*;

@DynamoDBTable(tableName = "your_table_name")
public class YourTableItem {
    private String id;
    private String name;

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

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

    @DynamoDBAttribute(attributeName = "name")
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

// 在代码中使用DynamoDBMapper执行操作
DynamoDBMapper mapper = new DynamoDBMapper(dynamoDBClient);

// 保存项到DynamoDB表
YourTableItem item = new YourTableItem();
item.setId("1");
item.setName("John Doe");
mapper.save(item);

// 从DynamoDB表加载项
YourTableItem loadedItem = mapper.load(YourTableItem.class, "1");
System.out.println(loadedItem.getName());

// 更新项
loadedItem.setName("Jane Smith");
mapper.save(loadedItem);

// 删除项
mapper.delete(loadedItem);
