JAVA查询MYSQL时乱码错误
我用JAVA向MYSQL查询数据的时候，后台打印出的中文都没问题，可是编写SQL语句进行数据库查询时就提示乱码，我的语句是：String sql="set names 'gbk';select * from commitment where majorclass like '%"+department+"%' and tname='"+tname+"' and title='"+title+"' ;";其中的department和tname以及title在后台打印都正常显示，可是执行的时候就提示乱码了。我的MYSQL编码是前台用GBK编码，后台存储用UTF8，my.ini文件是这样的
[client]

port=3306

[mysql]

default-character-set=gbk  


# SERVER SECTION
# ----------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.
#
[mysqld]

# The TCP/IP Port the MySQL Server will listen on
port=3306


#Path to installation directory. All paths are usually resolved relative to this.
basedir="D:/MyFile/MYSQL/"

#Path to the database root
datadir="C:/ProgramData/MySQL/MySQL Server 5.1/Data/"

# The default character set that will be used when a new schema or table is
# created and no character set is defined
default-character-set=utf8




这个该怎么解决呢

------解决方案--------------------
1 SET NAMES utf-8;
2 将你的SQL 字串字段转为 utf-8 编码...
------解决方案--------------------
页面编码和数据库编码保持一致就可以了。
