通过修改字符集编码为utf8，彻底解决中文问题。
一. 登录MySQL查看用SHOW VARIABLES LIKE ‘character%’；下字符集，显示如下：
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
character_set_database和character_set_server的默认字符集还是latin1。
二. 修改mysql的my.cnf文件中的字符集键值
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
collation-server = utf8_unicode_ci
init-connect=’SET NAMES utf8′
character-set-server = utf8
或者直接命令行修改：
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;
重启mysql服务即可。
注意：命令行修改只对当前状态有效，重启失效。彻底解决请修改文件。
