如何获取HBASE中每个列族的列数

import org.apache.hadoop.conf.Configuration;

import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.client.Admin;
import org.apache.hadoop.hbase.client.Connection;
import org.apache.hadoop.hbase.client.ConnectionFactory;

public class HBaseColumnCount {
    public static void main(String[] args) {
        Configuration config = HBaseConfiguration.create();
        try (Connection connection = ConnectionFactory.createConnection(config);
             Admin admin = connection.getAdmin()) {
            TableName tableName = TableName.valueOf("your_table_name");
            HTableDescriptor tableDescriptor = admin.getTableDescriptor(tableName);
            HColumnDescriptor[] columnFamilies = tableDescriptor.getColumnFamilies();
            for (HColumnDescriptor columnFamily : columnFamilies) {
                String columnFamilyName = columnFamily.getNameAsString();
                int columnCount = columnFamily.getValues().size();
                System.out.println("Column Family: " + columnFamilyName);
                System.out.println("Column Count: " + columnCount);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
