Java 代码优化：提高数据插入效率

public void insertData(outqjSqlStruct pressure, String sqlname) { String sql = 'INSERT ignore into ' + sqlname + ' (entity_id, key, ts, dbl_v, json_v, device_name) VALUES (?, ?, ?, ?, ?, ?)'; try (Connection conn = new connection().getConnection2(); PreparedStatement pstmt = conn.prepareStatement(sql)) { pstmt.setString(1, pressure.getValue()); pstmt.setString(2, pressure.getValue1()); pstmt.setString(3, pressure.getValue3()); pstmt.setDouble(4, pressure.getValue2()); pstmt.setString(5, pressure.getValue5()); pstmt.setString(6, pressure.getValue4());

    pstmt.executeUpdate();
} catch (SQLException e) {
    e.printStackTrace();
}

}

// 简化了 try-with-resources 块，将连接和语句对象合并。 // 移除不必要的 connection.destroy() 方法调用。 // 添加了适当的缩进和间距，提高可读性。
