1. 代码
SHOW VARIABLES LIKE 'character_set_%'; 查看一下 显示
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8|
| character_set_connection | utf8|
| character_set_database | latin1 |
| character_set_results | utf8|
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /home/jh/mysql/share/mysql/charsets |
2. 代码
SHOW VARIABLES LIKE 'collation_%';
+----------------------+-------------------+
| Variable_name | Value |
+----------------------+-------------------+
| collation_connection | utf8_swedish_ci |
| collation_database | latin1_swedish_ci |
| collation_server | latin1_swedish_ci |
+----------------------+-------------------+
红色字体部分为问题部分，解决方法如下：
set character_set_database =utf8;
set character_set_results =utf8;
set character_set_server =utf8;
set character_set_system =utf8; --此处utf-8也可以
然后执行：
SET collation_server = utf8_general_ci;
SET collation_database = utf8_general_ci;
执行完以后，请检查mysql数据库下的每个库，表，字段是否都是utf8，如果不是话，改成utf8格式;3. 修改mysql安装目录下的my.ini文件
[mysql]
default-character-set=utf8
配置好后，重启mysql。
另外存储过程也需要注意一下。
