 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/ |+--------------------------+------------------------------------------------+
