如何在java中获取bigquery表模式？

<dependency>

import com.google.cloud.bigquery.BigQuery;
import com.google.cloud.bigquery.BigQueryOptions;
import com.google.cloud.bigquery.Field;
import com.google.cloud.bigquery.Schema;
import com.google.cloud.bigquery.Table;
import com.google.cloud.bigquery.TableId;

public class BigQuerySchemaExample {
    public static void main(String[] args) {
        // 创建BigQuery客户端实例
        BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();

        // 定义表的ID
        TableId tableId = TableId.of("project-id", "dataset-id", "table-id");

        // 获取表的元数据
        Table table = bigquery.getTable(tableId);

        // 获取表的模式
        Schema schema = table.getDefinition().getSchema();

        // 遍历模式中的字段
        for (Field field : schema.getFields()) {
            System.out.println("字段名：" + field.getName());
            System.out.println("字段类型：" + field.getType());
            System.out.println("字段模式：" + field.getMode());
            System.out.println("--------------");
        }
    }
}
