示例1: insert

/**
 * use JDBC template PreparedStatement to insert records
 * require record to have getAllValues() and optional getDbColumnNames() method
 * @return boolean if the insert is successful
 * @throws SQLException
 */
public boolean insert() throws SQLException, IllegalAccessException {
  if (records.size() == 0 || !(records.get(0) instanceof AbstractRecord)) {
    logger.debug("DatabaseWriter no record to insert or unknown record Class.");
    System.out.println("DatabaseWriter no record or unknown record Class: " + records.size() + " | " + records.get(0) + " | " + (records.get(0) instanceof AbstractRecord));
    return false;
  }

  final AbstractRecord record0 = (AbstractRecord) records.get(0);
  final String[] columnNames = record0.getDbColumnNames();
  final String sql =
      (columnNames != null) ? PreparedStatementUtil.prepareInsertTemplateWithColumn(tableName, columnNames)
          : PreparedStatementUtil.prepareInsertTemplateWithoutColumn(tableName, record0.getAllFields().length);
  logger.info("sql string: " + sql);
  logger.error("columnNames: " + columnNames);
  System.out.println("sql: " + sql + " | " + columnNames);
  //logger.debug("DatabaseWriter template for " + record0.getClass() + " : " + sql);

  for (final Record record : records) {
    jdbcTemplate.update(sql, ((AbstractRecord) record).getAllValuesToString());
  }
