解决Mysql5.7中文乱码的问题

 在使用mysql5.7时,会发现通过web端向数据库中写入中文后会出现乱码,但是在数据库中直接操作SQL语句插入数据后中文就显示正常,这个问题怎么解决呢?此处不对MySQL的数据编码过程和原理进行讲解,如果有兴趣的同学可以自己百度。

下面我们就直接使用如下操作解决:

一、打开mysql控制台,输入命令show variables like 'character%';

  显示如下:

 +--------------------------+-------------------------------------------+
| Variable_name      | Value                   |
+--------------------------+-------------------------------------------+
| character_set_client   | latin1                  |
| character_set_connection | latin1                  |
| character_set_database  | utf8                   |
| character_set_results  | latin1                  |
| character_set_server   | utf8                   |
| character_set_system   | utf8                   |
| character_sets_dir    | C:\MySQL\MySQL Server 5.0\share\charsets\ |
+--------------------------+-------------------------------------------+

二、修改my.ini文件

 [client]

  default-character-set=utf8

  [mysqld]
  default-storage-engine=INNODB
  character-set-server=utf8
  collation-server=utf8_general_ci

三、重启后使用第一步的命令查看,如下:

  +--------------------------+----------------------------+
| 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 | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

还有character_set_database和character_set_server的默认字符集还是latin1。

四、输入命令:set names utf8;

  重启后,使用第一步命令查看:

+--------------------------+------------------------------------------------+
| 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 |
| character_sets_dir | C:\wamp64\bin\mysql\mysql5.7.9\share\charsets\ |
+--------------------------+------------------------------------------------+

除了character_set_filesystem是binary外,其他都是utf8了,

这样在web端也设置成utf8编码就可以正常输入数据库了。
