latin1即是iso8859-1, 所以在插入之前需要将内容转换为iso8859-1, 如下:
代码如下 复制代码
encoding iso88591 = encoding.getencoding(iso8859-1);
encoding df = encoding.default;
byte[] gb2312bytes = df.getbytes(content);
//byte[] asciibytes = encoding.convert(df, iso88591, gb2312bytes);
tring str = iso88591.getstring(gb2312bytes);
这样转换之后 ，source中不用加入charset参数 ，程序中也不需要先执行set names **, 即可正常插入
如果是mysql服务器我们不知道编码可参考下面方法解决
mysql的字符集是utf8的，光看这点害人不浅。登录，mysql -uroot -p,进入mysql。
命令：show variables like 'character_set_%';
代码如下 复制代码
+--------------------------+----------------------------+
| variable_name | value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
只有character_set_system是utf8。
vi /etc/my.cnf
mysql的默认配置文件以及目录
编辑如下：
[mysqld]
代码如下 复制代码
default-character-set=utf8
之后：service mysql stop
service mysql start
重启后，再次查看show variables like 'character_set_%';
代码如下 复制代码
+--------------------------+----------------------------+
| variable_name | value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
此时，character_set_database已经是utf8，工程已经不再乱码。
可以再添加如下一句：
代码如下 复制代码
[client]
default-character-set=utf8
也可登录的时候， 要用以下命令：mysql --default-character-set=utf8 -u root -p
则：
代码如下 复制代码
+--------------------------+----------------------------+
| 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 | /usr/share/mysql/charsets/ |
最后如果你是php连接mysql中文乱码可参考下办法解决
就是在mysql_connect后面加一句set names utf8，即可使得utf8的消除乱码，对于gbk的则使用set names gbk，代码如下：
代码如下 复制代码
$mysql_mylink = mysql_connect($mysql_host, $mysql_user, $mysql_pass);
mysql_query(set names 'gbk');
