Hibernate操作Mysql数据库乱码问题
|||
Mysql数据库：
安装时选择字符集为gbk；
配置时选择字符集为gbk；
创建数据库选择字符集为utf8
create database eschool default charset utf8 collate utf8_unicode_ci;
创建表时支持中文
CREATE TABLE `xtuser` (
`id` int(10) NOT NULL,
`username` varchar(50) NOT NULL,
`password` varchar(50) NOT NULL,
`logintime` date default NULL,
`enable` int(1) default NULL,
`grade` int(2) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=gbk
上述操作后,通过client客户端可以正常insert中文。
Hibernate连接配置时勿忘加
<property name="url" value="jdbc:mysql://localhost:3306/sim?useUnicode=true&characterEncoding=UTF-8"></property>
保证与数据库字符集对应。
附：查看数据库、表字符集设置命令
mysql> show variables like '%chara%';
