今日重点设计了HBase后端数据插入模块，基于Java API实现了高性能的写入方案。以下为关键代码实现及技术要点：
HBase数据插入工具类
支持单条插入和批量写入操作
public class HBaseInserter {
private static final Logger logger = LoggerFactory.getLogger(HBaseInserter.class);

/*** 单条数据插入方法* @param tableName 表名* @param rowKey 行键* @param columnFamily 列族* @param qualifier 列限定符* @param value 数据值*/
public void insertData(String tableName, String rowKey, String columnFamily, String qualifier, String value) throws IOException {try (Connection connection = ConnectionFactory.createConnection();Table table = connection.getTable(TableName.valueOf(tableName))) {Put put = new Put(Bytes.toBytes(rowKey));put.addColumn(Bytes.toBytes(columnFamily),Bytes.toBytes(qualifier),Bytes.toBytes(value));table.put(put);logger.info("数据插入成功 - RowKey: {}", rowKey);} catch (IOException e) {logger.error("HBase插入失败: {}", e.getMessage());throw new IOException("数据写入HBase失败", e);}
}/*** 批量插入数据* @param tableName 表名* @param dataList 数据列表*/
public void batchInsert(String tableName, List<HBaseData> dataList) throws IOException {try (Connection connection = ConnectionFactory.createConnection();Table table = connection.getTable(TableName.valueOf(tableName))) {List<Put> puts = new ArrayList<>();for (HBaseData data : dataList) {Put put = new Put(Bytes.toBytes(data.getRowKey()));put.addColumn(Bytes.toBytes(data.getColumnFamily()),Bytes.toBytes(data.getQualifier()),Bytes.toBytes(data.getValue()));puts.add(put);}table.put(puts);logger.info("批量插入完成，共{}条数据", dataList.size());} catch (IOException e) {logger.error("批量插入失败: {}", e.getMessage());throw new IOException("批量写入HBase失败", e);}
}

}

/**

  class HBaseData {
  private String rowKey;
  private String columnFamily;
  private String qualifier;
  private String value;
  }
