1.使用 schemaExport(hibernate5.2.3)建立Mysql表 sql
@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.使用上面的代码能够生成SQL可是建表别没有成功;ui
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;spa
[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.通过查找发现是hibernate里的dialect和Mysql的版本不匹配,SQL语句里的type=InnoDB使用在MySQL5.0以前,5.0以后就要是使用engine=InnoDBhibernate
MySql5.0以前的配置 <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> 5.0以后须要使用 <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
4.修改后的hibernate生成SQL语句以下,建表成功;code
Hibernate: create table User ( id integer not null, age integer, name varchar(255), primary key (id) ) ENGINE=InnoDB
