JMeter JDBC连接Mysql时的乱码问题

1、Mysql如果编码为：

mysql> show variables like 'char%';

+--------------------------+-----------------------------+

| Variable_name            | Value                       |

+--------------------------+-----------------------------+

| character_set_client     | utf8                        |

| character_set_connection | utf8                        |

| character_set_database   | latin1                      |

| character_set_filesystem | binary                      |

| character_set_results    | utf8                        |

| character_set_server     | latin1                      |

| character_set_system     | utf8                        |

| character_sets_dir       | /apps/mysql/share/charsets/ |

+--------------------------+-----------------------------+

8 rows in set (0.04 sec)

那么在JMeter这边通常无法插入中文：

Incorrect string value: '\x85\x85????...' for column 'c1' at row 1

服务端需要修改：

mysql> set names 'gbk';

Query OK, 0 rows affected (0.00 sec)

mysql> show variables like 'char%';

+--------------------------+-----------------------------+

| Variable_name            | Value                       |

+--------------------------+-----------------------------+

| character_set_client     | gbk                         |

| character_set_connection | gbk                         |

| character_set_database   | latin1                      |

| character_set_filesystem | binary                      |

| character_set_results    | gbk                         |

| character_set_server     | latin1                      |

| character_set_system     | utf8                        |

| character_sets_dir       | /apps/mysql/share/charsets/ |

+--------------------------+-----------------------------+

8 rows in set (0.00 sec)

2、JMeter JDBC定义的连接池URL需要增加参数：characterEncoding=UTF-8

另外，mysql表的编码查询方法：

show full columns from xxx;
