Hibernate + MySQL:如何设置数据库和表的utf-8编码
Hibernate + MySQL:如何设置数据库和表的utf-8编码
提问于 2012-10-25 15:08:54
我的系统运行在Linux Mandriva，RDBMS - MySQL 5上。我需要在UTF-8中创建数据库和表。
以下是hibernate.cfg.xml的一个片段-
...
<property name="hibernate.hbm2ddl.auto">create-drop</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.characterEncoding">utf8</property>
...my.cnf -
# The MySQL server
[mysqld]
...
default-character-set=cp1251
character-set-server=cp1251
collation-server=cp1251_general_ci
init-connect="SET NAMES cp1251"
skip-character-set-client-handshake
...
[mysqldump]
...
default-character-set=cp1251
...例如，某些类-
@Entity
@Table(name = "USER")
public class User {
@Id
@Column(name = "USERID")
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Column(name = "USERNAME")
private String name;
@Column(name = "USERPASSWORD")
private String password;
@Column(name = "USERIP")
private String ip;
// getter's and setter's here
...但是当生成这些表时，我看到了latin1的编码示例-
SHOW CREATE TABLE USER;
USER | CREATE TABLE `user` (
`USERID` int(11) NOT NULL auto_increment,
`USERIP` varchar(255) default NULL,
`USERNAME` varchar(255) default NULL,
`USERPASSWORD` varchar(255) default NULL,
PRIMARY KEY (`USERID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |如何将编码更改为UTF-8
如果您能提供信息，我将不胜感激！谢谢!
..。
这很奇怪，我已经全部改成了utf8 -
# The MySQL server
[mysqld]
...
default-character-set=utf8
character-set-server=utf8
collation-server=utf8_general_ci
init-connect="SET NAMES utf8"
skip-character-set-client-handshake
...
[mysqldump]
...
default-character-set=utf8
...现在-
SHOW CREATE TABLE USER;
USER | CREATE TABLE `USER` (
`USERID` int(11) NOT NULL auto_increment,
`USERIP` varchar(255) default NULL,
`USERNAME` varchar(255) default NULL,
`USERPASSWORD` varchar(255) default NULL,
PRIMARY KEY (`USERID`)
) ENGINE=MyISAM DEFAULT CHARSET=cp1251 |页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
