1.使用 schemaExport(hibernate5.2.3)创建Mysql表
@Test public void testSchemaExport() { ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().configure().build(); Metadata metadata = new MetadataSources(serviceRegistry).buildMetadata(); SchemaExport schemaExport = new SchemaExport(); schemaExport.create(EnumSet.of(TargetType.DATABASE), metadata); }
2.使用上面的代码可以生成SQL但是建表别没有成功;
Hibernate: create table User ( id integer not null, age integer, name varchar(255), primary key (id) ) type=InnoDB
把hibernate生成的SQL语句在Navicat中执行出现错误;
[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘Hibernate: create table User ( id integer not null, age ‘ at line 1
3.经过查找发现是hibernate里的dialect和Mysql的版本不匹配,SQL语句里的type=InnoDB使用在MySQL5.0之前,5.0之后就要是使用engine=InnoDB
MySql5.0之前的配置 <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> 5.0之后需要使用 <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
4.修改后的hibernate生成SQL语句如下,建表成功;
Hibernate: create table User ( id integer not null, age integer, name varchar(255), primary key (id) ) ENGINE=InnoDB
