調整mysql字元設定解決kettle ETL時出現的亂碼

從生產環境抽取資料至倉庫時，發現目標庫中的漢字是亂碼。我的環境是從mysql至mysql，暫時沒有異構資料庫，架構比較簡單。解決這個問題方法是調整mysql伺服器的字元集，確保如下：

 mysql> show variables like 'char%';

+--------------------------+--------------------------------------------------------+
| Variable_name            | Value                                                  |
+--------------------------+--------------------------------------------------------+
| character_set_client     | utf8                                                   |
| character_set_connection | utf8                                                   |
| character_set_database   | utf8                                                   |
| character_set_filesystem | binary                                                 |
| character_set_results    | utf8                                                   |
| character_set_server     | utf8                                                   |
| character_set_system     | utf8                                                   |

 如果在設定之後，仍然出現亂碼時就需要檢查建庫指令碼中的字條集是否也是utf8。
